Determine whether pursuit movements are conjugate. Pursuit eye movementsare used to followa moving target. Rothbaum, B.O., Astin, M.C., & Marsteller, F. (2005). For example, perception of timbre, such as hearing differences in the way different musical instruments sound, involves comparison of different intensities across frequencies. (2005). The ability to consciously locate an object or target amongst a complex array of stimuli has been Most characteristic of nuclear involvement is unilateral palsy of the third cranial nerve in conjunction with weakness of bilateral superior recti muscle and bilateral ptosis. Heins et al. Journal of EMDR Practice and Research, 2, 51-56. Twenty-one patients with single-event PTSD (average IES: 49.5) received three consecutive sessions of EMDR with three different types of auditory and kinesthetic stimulation. Data from successful treatment at other disaster sites are also reported. (2004). Eye movement desensitization reprocessing facilitates attentional orienting. (2006). Perkins, B.R. Puffer, M.; Greenwald, R. & Elrod, D. (1997). Homer, S. R., Deeprose, C., & Andrade, J. Journal of EMDR Practice and Research, 2, 239-246 Treating post-traumatic stress disorder in patients with multiple sclerosis: A randomized controlled trial comparing the efficacy of eye movement desensitization and reprocessing and relaxation therapy. 2. (2011). Shapiro, F. (2007). Corrections? Does the patient falter at certain positions of gaze? (2014). Results indicated that patients receiving EMDR had significantly fewer therapy sessions over 10 weeks but had significantly greater gains in their PCLM scores than did individuals not receiving EMDR. Emotional Freedom Techniques, J Nerv Ment Dis199:372378. The development of a cognitive self is also Clinical Case Studies. Eye movement includes the voluntary or involuntary movement of the eyes. It is a highly vascular structure that projects into the vitreous humor. New York: Guilford Press. Examination of ocular movements involves the assessment smooth pursuit movements followed by saccades. Efficacy of the eye movement desensitization procedure in the treatment of traumatic memories. Journal of Clinical Psychology and Psychotherapy, 9, 299-318. http://dx.doi.org/10.1037/tra0000120. http://www.istss.org/treating-trauma/new-istss-prevention-and-treatment-guidelines.aspx. Journal of EMDR Practice and Research, 5, 34-41. However, alternating stimulation appeared to confer an additional benefit to the EMDR procedure. Kemp M., Drummond P., & McDermott B. Sometimes the mind is not able to plan in advance and the speech is rushed out. EMDR was superior to both control conditions in the amelioration of both PTSD symptoms and depression. Lilley, S.A., Andrade, J., Graham Turpin, G.,Sabin-Farrell, R., & Holmes, E.A. The peak angular speed of the eye during a saccade reaches up to 700/s in humans for great saccades (25 of visual angle); in some monkeys, peak speed can reach 1000/s. 3. (Torsion is clockwise or counterclockwise rotation around the line of sight when the eye is at its central primary position; defined this way, Listing's law says that, when the head is motionless, torsion is kept at zero. (2007). Trauma characterized by intention to harm is associated with childrens reports of psychotic symptoms. Relative to the control condition (imagery only), those who made eye movements whilst holding a mental image of this scenario in-mind demonstrated a significant decrease in heart rate, which acted as a measure of emotionality. Our data suggest a high and continuous number of life events prior to affective episodes. Twenty-one patients with single-event PTSD (average IES: 49.5) received three consecutive sessions of EMDR with three different types of auditory and kinesthetic stimulation. In addition, the counting task had no effect on vividness compared to exposure only, suggesting that the eye-movement task had a specific effect rather than serving as a general distractor (p. 317). Novo, P. et al. The effects of saccadic bilateral eye movement were compared to vertical eye movements and no eye movements on the retrieval of item, associative and contextual information. Fifteen-month follow-up of eye movement desensitization and reprocessing (EMDR) treatment of post-traumatic stress disorder and psychological trauma. However, since EMDR achieves clinical effects without the need for homework, or the prolonged focus used in exposure therapies, attention has been paid to the possible neurobiological processes that might be evoked. Smooth pursuit helps an individual track moving targets in the environment and stabilize gaze. Pursuit eye movements allow us to follow an object as it moves. Devilly, G.J., & Spence, S.H. The double Maddox rod test helps identify and quantify torsional misalignment when vertical diplopia is present. Perhaps EMDR reduces distress thereby activating a cholinergic effect known to improve ocular pursuit. In skew deviation, which is related to otolith dysfunction, supine positioning may reduce the vertical deviation due to decrease in firing of the vestibulo-ocular reflex. Eye movements were superior to control conditions in reducing within-session image vividness and emotionality. At about seven months, infants are able to perceive depth in a flat, two-dimensional picture. A special type of eye movement, rapid eye movement, occurs during REM sleep. The function's main purpose is to prevent an otherwise significant smearing of the image. Visual search can take place with or without eye movements. Perhaps EMDR reduces distress thereby activating a cholinergic effect known to improve ocular pursuit. Specifically citing the hypothesis that EMDR induces processing effects similar to REM sleep (see also Stickgold, 2002, 2008), polysomnograms indicated a change in sleep patterns post treatment, and improvement on all measures including anxiety, depression, and quality of life after a mean of five sessions. Advance online publication. (2002). Irritation of the eye surface; Alteration in the tear film; Visual hallucinations; Decreased eye convergence; Blepharospasm; Abnormalities in ocular pursuit, ocular fixation and saccadic movements; Difficulties opening the eyelids This can have particular relevance when driving. Bilateral eye movements, attentional flexibility and metaphor comprehension: The substrate of REM dreaming? Increased memory retrieval in two experiments support the possibility that alternating bilateral activation of the left and right hemispheres exerts its effects on memory by increasing the functional connectivity between the two hemispheres. Interestingly, patients preferences did not follow this pattern: the perceived effectiveness was higher for tones than for EMs. Vol. Tested their theory that eye movements change the somatic perceptions accompanying retrieval, leading to decreased affect, and therefore decreasing vividness. Uribe, M. E. R., & Ramirez, E. O. L. (2006). Both EMDR and exposure therapy plus cognitive restructuring (with daily homework) produced significant improvement. Of the different psychotherapies, EMDR and CBT were stated to be the treatments of choice for trauma victims. Whereas low spatial frequencies (the 'fuzzier' parts) are attenuated, higher spatial frequencies (an image's fine details) that would otherwise be blurred by the eye movement remain unaffected. Eye-movements and visual imagery: a working memory approach to the treatment of post-traumatic stress disorder. https://eyewiki.org/w/index.php?title=Basic_Approach_to_Diplopia&oldid=84040. Jarero, I., & Artigas, L. (2010). Bilateral eye movements enhance the retrieval of episodic memories. Smooth pursuit, which uses cones, is how we pull the trigger. (2015). Osorio, A., Perez, M., Tirado, G., Jarero, I., Givaudan, M. (2018). A school- based EMDR intervention for children who witnessed the Pirelli building airplane crash in Milan, Italy. Utrecht, Netherlands. Practice Guideline for the Treatment of Patients with Acute Stress Disorder and Posttraumatic Stress Disorder. Vergence eye movements allow us to move our eyes in different directions 2 Marcus, S., Marquis, P. & Sakai, C. (2004). [13][14][15] Although, depending on the demands on timing accuracy, acceleration-based methods are more precise. Structure. Pursuit eye movements are especially important in driving and sports. (2003). (2016). . Journal of Psychotraumatology and Psychological Medicine, 1, 47 -57. Infants first become sensitive at about two months to kinematic, or motion-carried information for distance, as when one surface moves in front of another. For example, During right gaze, the right lateral rectus and left medial rectus receive equal and simultaneous innervation. Even an initial glimpse of a scene has an influence on subsequent eye movements. Thus, in this example, this three step test implicates paresis of the right superior oblique muscle. Journal of Behavior Therapy and Experimental Psychiatry, 44, 447483. (1997). European Journal of Psychotraumatology, 7. Infants are able to recognize familiar faces despite variations in expression and perspective. The EMDR group also improved on all standardized measures at 18 months follow up (Edmond & Rubin, 2004, Journal of Child Sexual Abuse). Research indicates that CBT and EMDR therapy are superior to all other treatments. Neuroanatomical changes after EMDR in posttraumatic stress disorder. The alternate cover test is useful for detecting underlying deviations kept in check by fusion. Marcus, S., Marquis, P. & Sakai, C. (1997). Bilateral saccadic eye movements were compared to vertical and no eye movements. Ohta ni, T., Matsuo, K., Kasai, K., Kato, T., & Kato, N. (2009). A review of trauma protocols. Sleep-dependent memory processing and EMDR action. In patients with chronic psychotic disorders PE and EMDR not only reduced PTSD symptoms, but also paranoid thoughts. Assess for pupil constriction during accommodation and for relative afferent pupillary defect to look for associated optic neuropathy. Based on strong evidence and a preponderance of harm over benefit, clinicians should not include voluntary saccadic or smooth-pursuit eye movements in isolation (ie, without head movement) as specific exercises for gaze stability. Because the standardized IE procedures used were those employed in-session during [prolonged exposure] the results are also instructive regarding the relative efficacy of both treatments without the addition of homework. Eye movement desensitization and reprocessing: Basic principles, protocols and procedures (2nd ed.). An example is speech, which can be simultaneously heard and seen in a talking face. Two example trials, in which the target either accelerated (Fig. Kapoula Z, Yang Q, Bonnet A, Bourtoire P, & Sandretto J (2010). Most intermodal relations in the world, however, are quite specific rather than arbitrary. Errebo, N. & Sommers-Flanagan, R. (2007). Andrade, J., Kavanagh, D., & Baddeley, A. This national registry (NREPP) cites EMDR as evidence-based practice for treatment of PTSD, anxiety and depression symptoms. At four-month follow up, teachers reported that all but two children evinced a return to normal functioning after treatment. Tracking Deficit: Eyes jump backward and forwardand fall on lines above or below during return sweeps. This is followed by longer fixations and shorter saccades in the latter phases of scene viewing processing. Convergence insufficiency relates to exo-deviation greater at near than at distance fixation. Multiple neuropathies are worrisome as they can be suggestive of brainstem, subarachnoid, cavernous sinus disease, or if involving the optic nerve can reflect orbital apex disease. Treating traumatic amputation-related phantom limb pain: A case study utilizing eye movement desensitization and reprocessing (EMDR) within the armed services. Factors which affect top-down processing (e.g. primates, rodents, flies, birds, fish, cats, crabs, octopus) to fixate, inspect and track visual objects of interests. Saccades involve anyshift in gaze, such as from road sign to speedometer, board to paper, notes to computer screen. The Substance Abuse and Mental Health Services Administration (SAMHSA) is an agency of the US Department of Health and Human Services (HHS). . The alternate cover test detects phorias by breaking fusion. The functions of each type of eye movement are introduced here; in subsequent sections, the neural circuitry responsible for three of these types of movements is presented in more detail (see Chapters 14 and 19 for further discussion of Two example trials, in which the target either accelerated (Fig. The eyes are the visual organs of the human body, and move using a system of six muscles. Using an Adaptive Information Processing conceptualization a wide range of family problems and impasses can be addressed through the integration of EMDR and family therapy techniques. Psychotherapy and Psychosomatics,85(6), 357-365. Twenty-six children (average age 10.4 years) with behavioral problems were randomly assigned to receive either 4 sessions of EMDR or CBT. Eye movement in music reading may at first appear to be similar to that in language reading, since in both activities the eyes move over the page in fixations and saccades, picking up and processing coded meanings. Journal of Forensic Psychiatry and Psychology, 17, 538-562. It is also thought that perceptual memory is updated during saccades so that information gathered across fixations can be compared and synthesized. The masking of an image[27] and other degradations, such as a decrease in luminance, during fixations (factors which affect bottom-up processing), have been found to increase the length of fixation durations. The superior oblique muscle and inferior oblique muscle attach at angles to the eyeball. EMDR in the treatment of chronic phantom limb pain. The impact of taxing working memory on negative and positive memories. SAMHSA's National Registry of Evidence-based Programs and Practices (2011). Look for lag in eye movements. Jarero, I., Artigas, L., Lopez-Lena, M. (2008). Russell, M.C. Their review of the evidence also indicated that EMDR leads to an improvement in mental health functioning. . But infants do not always prefer speech. When adults hear a syllable while looking at a face producing a different syllable, they tend to perceive the sound associated with the lip movements rather than the actual phoneme that they heard. Processing of etiological disturbing memories, triggers and templates resulted in complete remission of Major Depressive Disorder in two teenagers. Eye movement measurements are also used to investigate psychiatric disorders. Three cranial nerves carry signals from the brain to control the extraocular muscles. Copyright 2020 - 2021 Optography, Anatomy and physiology of ocular movement, Electro optical devices in low vision - Optography, EXTENDED WEAR CONTACT LENS INTRODUCTION - Optography. This enhances color accuracy, reduces eye fatigue, increases depth perception, and provides greater visual detail. A different recovery pattern was observed with the EMDR group demonstrating a more rapid decline in self-reported distress. The frontal eye fields (FEF) are a region located in the frontal cortex, more specifically in Brodmann area 8 or BA8, of the primate brain.In humans, it can be more accurately said to lie in a region around the intersection of the middle frontal gyrus with the precentral gyrus, consisting of a frontal and parietal portion. The FEF is responsible for saccadic eye movements for the Divergence insufficiency refers to esodeviation that is greater at distance than near fixation. Shapiro, F. (2012). (2008). Journal of Consulting and Clinical Psychology, 71, 330-338. The findings suggest that therapy aimed at processing memories of past dental events can be helpful for patients with dental phobia. However, the entire visual image is not updated during each saccade. The relationship between efficacy and methodology in studies investigating EMDR treatment of PTSD. Eye movement desensitization and reprocessing (EMDR): Treatment for psychologically traumatized individuals. EMDR therapy: An overview of current and future research. Significant differences were obtained and maintained at 3-month follow up. The avian retina is highly developed. Some scientists believe that this is the same as visual working memory, but as in spatial updating the eye movement has to be accounted for. A multidimensional meta-analysis of psychotherapy for PTSD. Discordance in psychotic illness across related individuals can be traced to differential exposure to trauma. Special Issue Call for Papers: Metabolic Psychiatry. Funded by Kaiser Permanente, follow-up evaluation indicates that a relatively small number of EMDR sessions result in substantial benefits that are maintained over time. Traumatology, 12, 121-129. Shapiro, F. (2014). Madrid, A., Skolek, S., & Shapiro, F. (2006). Four sessions of Eye Movement Desensitization and Reprocessing (EMDR) led to elimination of PLP, and a significant reduction in PTSD, depression, and phantom limb tingling sensations. Participants reported a greater decline in emotionality and concentration after eye movements in comparison to recall-only and recall-with-music. (2004). Unlike CBT with a trauma focus, EMDR does not involve (a) detailed descriptions of the event, (b) direct challenging of beliefs, (c) extended exposure, or (d) homework." Time-course of eye movement-related decrease in vividness and emotionality of unpleasant autobiographical memories. International Journal of Stress Management, 13. A saccade is a rapid, conjugate, eye movement that shifts the center of gaze from one part of the visual field to another. . Kowal, J. doi:10.1016/j.jpsychires.2009.10.014. Pursuit eye movements are especially important in driving and sports. Perception of low frequencies is poor in young infants relative to high frequencies. 53. The efferent ocular motor pathway is divided into supranuclear, nuclear and internuclear segments. Parents: If your childhas difficulty with these activities, it could indicate he/she has an undetected vision problem. All were clinically useful. Soberman, G. B., Greenwald, R., & Rule, D. L. (2002). Sack, M., Lempa, W., & Lemprecht, W. (2007). EMDR processing of experiential contributors to bonding disruption, in addition to current triggers, and a memory template of an alternative/problem free pregnancy and birth resulted in the repair of maternal bonding, analogous to the positive findings with the repair of disrupted attachment. [21] In these cases, it was noticed that the patients would make hypometric (small) saccades with the affected eye, and that they were able to correct these errors over time. 1. Polanczyk, G. Moffitt, T.E. There was significant difference between the mean YaleBrown scores of the two groups after treatment and EMDR was more effective than citalopram in improvement of OCD signs. The six muscles are the lateral, medial, inferior and superior recti muscles, and the inferior and superior oblique muscles. If a child cannot control these eye movements, hell lose his place and comprehension becomes a problem. (2018). (2017). (2008). Neuropsychopharmacology, 29, 641648. & Lee, H. (1997). Landin-Romero, R., et al. Journal of behavior therapy and experimental psychiatry, 50, 77-82. [citation needed], Eye movement in scene viewing refers to the visual processing of information presented in scenes. The three-pronged protocol includes processing of the past events that have set the foundation for the pathology, the current triggers, and templates for appropriate future functioning to address skill and developmental deficits. Adults experience the world through the integration of sensory impressions. Neuroscience. & Lee, H. (1997). Comitant misalignment is typically found in patients with congenital or early-onset strabismus patients typically do not report double vision because of cortical suppression of one of the images. Faretta, E. (2013). From the two remaining muscles isolated from steps 1 and 2 of the three step test however, only the left superior rectus and right superior oblique remain. (2011). In addition, significantly more people in the DSM trauma-incongruent group met criteria for PTSD than those in the DSM trauma-congruent group. Ahmad A, Larsson B, & Sundelin-Wahlsten V. (2007). It is concluded that eye movements are effective when negative memories pertain to loss and grief. Traumatology, 12. Accurate, smooth pursuit eye movements allow us to make spatial judgments as to the speed and position of the moving target. Journal of Traumatic Stress Studies, 2, 199223. British Journal of Clinical Psychology, 48. All participants initially met two or more PTSD criteria. Eye movement desensitization and reprocessing treatment of Vietnam war veterans with PTSD: Comparative effects with biofeedback and relaxation training. This text provides description and clinical transcripts and an elucidation of the guiding Adaptive Information Processing model. Abduction ( Lateral Movement) Occurs However, in a process analysis, Rogers et al. It was found that bilateral eye movements increased true memory for the event, increased recollection, and decreased the magnitude of the misinformation effect. This study supports hypotheses regarding effects of interhemispheric activation and episodic memory. Traumatology-e, 3(2), Article 6. Results indicate that information processing during EMDR is followed by during-session decrease in psychophysiological activity, reduced subjective disturbance and reduced stress reactivity to traumatic memory. Ocular MG findings include ptosis, fatigability of muscles, and orbicularis weakness, Orbicularis peek sign (scleral show after short period of lid opposition to gentle closing pressure), the Cogans lid twitch sign (twitching of eyelid after downgaze and return to primary position), or enhancement of ptosis may suggest MG. Diplopia is a common symptom in neuro-ophthalmology. Results indicate efficacy of EMDR when effect sizes are based on comparisons between EMDR and non-established trauma treatment or no-treatment control groups, and incremental efficacy when effect sizes are based on comparisons between EMDR and established (CBT) trauma treatment. Ptosis and diplopia from ophthalmoplegia with an ipsilateral mydriatic pupil may suggest a third nerve palsy versus an ipsilateral miotic pupil and mild ptosis which may suggest a concomitant Horner syndrome. (2013). Barrowcliff, A.L., Gray, N.S., MacCulloch, S., Freeman, T. These changes were significantly greater compared to the control group. (2010). The medial rectus causes the eyeball to look inwards; the inferior rectus downwards and the superior rectus upwards. Dutch National Steering Committee Guidelines Mental Health Care (2003). Russell, M.C., & Silver, S.M. Journal of EMDR Practice and Research, 2, In this study the EMDR-IGTP was used with 16 bereaved children after a human provoked disaster in the Mexican State of Coahuila in 2006. [23] As noted in the WHO (2013) guidelines and the American Psychiatric Association Practice Guidelines (2004, p.18), in EMDR therapy traumatic material need not be verbalized; instead, patients are directed to think about their traumatic experiences without having to discuss them. Given the reluctance of many combat veterans to divulge the details of their experience, this factor is relevant to willingness to initiate treatment, retention and therapeutic gains. Kearns, M, Engelhard I. M. (2015). Efficacy of eye movement desensitization and reprocessing (EMDR) on depression in patients with myocardial infarction (MI) in a 12-month follow up. Schneider, J., Hofmann, A., Rost, C., & Shapiro, F. (2008). 50-56. Traumatology, 13, 4-10. An eye tracker is a device for measuring eye positions and eye movement.Eye trackers are used in research on the visual system, in psychology, in psycholinguistics, marketing, as an input device for human-computer interaction, and in 127135, Sherrington's law of reciprocal innervation, Eye movement desensitization and reprocessing, "The control of voluntary eye movements: new perspectives", "Eye fields in the frontal lobes of primates", https://www.ncbi.nlm.nih.gov/books/NBK10793/, "Artificial intelligence can predict your personality simply by tracking your eyes", "Visual Fixation Durations and Saccade Amplitudes: Shifting Relationship in a Variety of Conditions", "The maturation of eye movement behaviour: scene viewing characteristics in children and adults", "Modeling the role of salience in the allocation of overt visual attention", "The Contributions of Image Content and Behavioural Relevancy to Overt Attention", "Cultural variation in eye movement during scene perception", "Eye movements during scene viewing: Evidence for mixed control of fixation durations", "Asymmetrical control of fixation durations in scene viewing", http://www.utdol.com/online/content/topic.do?topicKey=neuro_op/2892&selectedTitle=1~150&source=search_result, Software system for simulating eye motility disorders and their surgical correction, https://en.wikipedia.org/w/index.php?title=Eye_movement&oldid=1104332206, Articles with dead external links from August 2019, Articles with permanently dead external links, Short description is different from Wikidata, Articles with unsourced statements from May 2022, Creative Commons Attribution-ShareAlike License 3.0, the involvement of one or both eyes; involving one eye they may be classified as, Patients with eye movement disorders may report, Maldevelopment (e.g. Ems outperformed tones while it remained unclear if tones add to recall only. The FEF is responsible for saccadic eye movements for the Cvetek, R. (2008). EMDR in the treatment of panic disorder with agoraphobia. At follow-up, 49% were no longer diagnosed with PTSD. Clinical Case Studies, 5, 403-420. Additional Neurobiological Evaluations (2008). Updates? Internuclear ophthalmoplegia (INO) is characterized by a slowed adducting saccadic velocity in one eye with abducting nystagmus in the fellow eye on horizontal gaze. Pursuit eye movements are especially important in driving and sports. The flocculus is contained within the flocculonodular lobe which is connected to the cerebellum. (2006). Psychological medicine,46(12), 2583-2593. & McGreenery, C.E. Journal of Clinical Psychology, 58, 77-97. Spierer A. Monocular diplopia is usually attributable to refractive or media abnormalities. Samson, J.A., Sheu, Y-S, Polcari, A. Onset, offset, variability and progression of symptoms can aid in diagnosis and direction of workup depending on etiology (e.g., infectious, inflammatory, neoplastic). Findings support a working memory account of EMDR and suggest that effects of beeps on negative memories are inferior to those of eye movements. Hurley, E.C. Tell-tale signs oftracking problems in school include frequent loss of place, skipping or transposing words,omitting entirelines, using a finger to follow print, moving the head rather than just the eyes, and poor comprehension because of scrambled text. Paresis reduces saccadic velocity, however, restrictive conditions should not. Comparison of EMDR and PE Both groups showed significant improvements in PTSD symptoms. The infranuclear pathway includes the peripheral ocular motor cranial nerves (CN III, IV, VI), the neuromuscular junction (e.g., MG), and the extraocular muscles themselves (e.g., thyroid eye disease). [2] The cover-uncover test is used to demonstrate a tropia. Do horizontal saccadic eye movements increase interhemispheric coherence? Nordic Journal of Psychiatry, 61, 54-61. The debilitating and costly effects of Results were maintained at 2.8-year follow-up. Look for movement of the uncovered eye to pick up fixation. A different recovery pattern was observed with the EMDR group demonstrating a more rapid decline in self-reported distress. A special type of eye movement, rapid eye movement, occurs during REM sleep. Once different types of auditory information have been received, they need to be organized into perceptually meaningful elements. . : (2010). (2002). In the second trimester of pregnancy, the inner ear becomes fully developed, allowing the fetus to have limited auditory experiences in the womb. On the other hand, opsoclonus or ocular flutter are composed purely of fast-phase saccadic eye movements. Childhood trauma and childrens emerging psychotic symptoms: A genetically sensitive longitudinal cohort study. These muscles arise from the common tendinous ring (annulus of Zinn) in the orbit (eye cavity), and attach to the eyeball. When the eye is abducted, the recti muscles are the prime vertical movers. Ask where the image separation is the greatest in order to define which extraocular muscles are involved. Levin, P., Lazrove, S., & van der Kolk, B. If there is no improvement with pinhole, one could consider cerebral monocular diplopia or polyopia which is bilateral and extremely rare. Annals of the New York Academy of Sciences, 821, 99-113. Results indicate that information processing during EMDR is followed by during-session decrease in psychophysiological activity, reduced subjective disturbance and reduced stress reactivity to traumatic memory. Changes in psychological symptoms and heart rate variability during EMDR treatment: A case series of subthreshold PTSD. EMDR treatment of autobiographic worries causing moderate distress resulted in an increase in the smoothness of pursuit [which] presumably reflects an improvement in the use of visual attention needed to follow the target accurately. Vergence eye movements allow us to move our eyes in different directions 2 The impact of eye movements and tones on disturbing memories of patients with PTSD and other mental disorders. Upon termination of therapy, the EMDR group continued to improve while the Fluoxetine participants again became symptomatic. Neurobiological studies have indicated significant effects, including changes in cortical, and limbic activation patterns, and increase in hippocampal volume.
