Divergence Insufficiency Revisited: Natural History of Idiopathic Cases and Neurologic Associations | Neurology | JAMA Ophthalmology | JAMA Network ObjectivesTo determine the natural history of primary divergence insufficiency and to identify clinical features that distinguish patients with this neurologica [Skip to Navigation] Patients with non-strabismic binocular vision disorderssuch as divergence insufficiency, basic esophoria and vertical heterophoriacan often benefit from treatment with prism, particularly relieving prism, while othersincluding those with convergence excess, convergence insufficiency, divergence excess or basic exophoriaare better managed with other treatment modalities, such as vision therapy or lenses.1 An option for prism patients is prescribing prism to relieve diplopia and asthenopia and concurrently having the patient do vision therapy to attempt to decrease or eliminate the amount of prism needed. Over a period of several months, the diplopia becomes more constant and is noticed while driving, watching television, and in other long-distance vision situations. The EOM angles in these patients ranged from 100 to . Her cover test revealed a 25 PD constant right esotropia with a 2 PD constant right hypotropia. Progressive supranuclear palsy. When considering whether it is appropriate to prescribe vertical prism for a patient with combined horizontal and vertical deviations, particularly for a patient with intermittent strabismus, first identify whether the vertical deviation is primary or secondary. Dr. Jenewein is an assistant professor at Salus University, Salus Universitys Principal Site Investigator for the Pediatric Eye Disease Investigator Group, a Fellow of the American Academy of Optometry and a Diplomate of the Binocular Vision, Perception and Pediatric Optometry Section of the Academy. If the patient gives a fusion response with or without prism but movement on the unilateral cover test is seen, then anomalous correspondence is suspected and relieving or corrective prism is not an appropriate management option. . The diverse conditions and sites of associated lesions of the patients with secondary divergence insufficiency in this series imply that secondary divergence insufficiency is not particularly localizing, nor is it necessarily specific for intracranial hypertension. All patients with primary divergence insufficiency had been specifically asked whether their double vision was preceded by a specific event. In this example, the patient will be asked to either relax his or her eyes to put the lion in the cage (diverge) or stimulate his or her eyes to put the lion in the cage (converge). Bilateral medial rectus muscle recession for divergence insufficiency pattern esotropia. Heavy Eye Syndrome in the Absence of High Myopia: A Connective Tissue Degeneration in Elderly Strabismic Patients. Weird vision divergence upon waking at night User Name: Remember Me: Password . All patients with primary divergence insufficiency had been specifically asked whether their double vision was preceded by a specific event. They concluded that GVRT performed with intraoperative monitoring under topical anaesthesia, precise correction of hypertropia up to 10 can be achievable. Relieving prism is often prescribed for patients with intermittent strabismus and sometimes for those with constant strabismus. PDF Divergence Insufficiency - Jama Classic causes of divergence insufficiency include the following: Raised intracranial pressure Chiari malformation From there, basic vergence exercises will be added in. Patients with convergence insufficiency will often complain of eye strain when looking at near objects (reading, writing, computer work, etc. Questions: 125. SHarbison METraviesa Antireflective coating is also beneficial for patients wearing prism lenses. Of note among this cohort of patients without strabismus, noncontinuous LR-SR bands were found in 5% of cases, and superotemporal bowing in 24% of cases. After identifying a patient who stands to benefit from a prism prescription, the next step is deciding how much prism to prescribe. All patients with double vision routinely were assessed for the speed of saccades and for the presence of nystagmus to identify signs of abducens nerve palsy or internuclear ophthalmoplegia. GBTobin Graded Vertical Rectus Tenotomy For Small Angle Cyclovertical Strabismus in Sagging Eye Syndrome. One study successfully treated 87 patients with divergence insufficiency between two and 18 prism diopters (PDs) with prism with none of the patients in the study requiring additional treatment or surgery.3 Another study found that 100% of patients with divergence insufficiency (30 patients) had success with prism.4. LBSharpe [2] A common a daily, home rehabilitation technique is to have the patient do push-up exercises (looking at an object intermittently moved in and out from the bridge of the nose) to decrease the near point of convergence. 126. Results from this study also supported previously published evidence of normal age-related connective tissue degeneration as there was a positive age effect in correlation to supero-temporal bowing of the LR-SR band.[9]. J AAPOS. Six patients underwent CT and 10 underwent MRI. Lets continue the conversation over on your social network of choice. However, they had a recurrence rate of almost 7% over their mean follow-up period of 39 months. Many of these patients had an established underlying disorder (eg, cerebellar degeneration) and were referred because of double vision. To begin therapy, many therapists will focus first on normalizing the accommodative system. reported a series of 57 patients underwent unilateral lateral rectus resection for distance esotropia deviations of 530 with 96.5% did not require further surgery.[11]. Retrospective survey of patients with divergence insufficiency. Cunningham Prism prescriptions often greatly improve the quality of life of your patients by reducing asthenopia and diplopia. Prism is gradually increased until a patient is able to appreciate the forms on the RDS test. To begin therapy, many therapists will focus first on normalizing the accommodative system. JLSharpe the accommodative and vergence systems are tightly correlated. 131. Vision therapy uses various exercises to train the connection between the eyes and the brain as more than 50% of the brain is dedicated to visual function. Diplopia Developed in Later Life, An Ophthalmologic Approach J AAPOS. Randomised clinical trial of the effectiveness of base-in prism reading glasses versus placebo reading glasses for symptomatic convergence insufficiency in children. Patients with DI typically complain of gradual onset, variable frequency, homonymous diplopia, which is worse at distance. There are many different ways to do this, but the best method to use depends on the type of binocular vision disorder for which you are prescribing. This ocular misalignment has two main types: esotropia and exotropia. It is most often related to raised intracranial pressure or Chiari malformation. Their symptom was controlled using prisms. With a trial frame, she was not able to appreciate RDS stereoacuity in-office. The additional literature on the subject of divergence insufficiency largely consists of small series of patients mainly reported in the precomputed tomography (CT) era and patients with neurologically isolated divergence insufficiency mixed with those who additionally had other signs of intracranial hypertension or a structural brain lesion.15,18-21 The purpose of my study was to describe a large series of patients with divergence insufficiency evaluated in the post-CT era to determine the natural history of neurologically isolated cases, to determine the spectrum of neurologic associations, and to identify clinical features that might be helpful in distinguishing those patients with an isolated disorder from those harboring neurologic disorders. [10] In 2013, Stager et al. Through her full plus spectacles, she still had a 14 PD constant right esotropia and a 2 PD constant right hypotropia. None of these patients developed signs of an underlying neurologic disorder during follow-up. No signs of orbital ischemia were present in the second patient. [5] Initially, most patients only notice intermittent binocular diplopia at long distances, such as in the theater or while driving. Convergence insufficiency | AOA A similar technique is used for rehabilitation: the patient is instructed to do push-up exercises (looking at an object intermittently moved in and out from the bridge of the nose) daily at home to decrease the near point of convergence.Divergence InsufficiencyDivergence insufficiency is characterized as follows: Comitant esotropia is present at distance but not at near. Ductions and versions are full. It is most often related to raised intracranial pressure or Chiari malformation.Classic causes of divergence insufficiency include the following: Raised intracranial pressure Chiari malformation Head trauma Intracranial hypotension (low CSF pressure syndrome) Cerebellar lesions Midbrain massAbnormal Horizontal Conjugate DeviationsGaze deviations are relatively common in large cerebral and pontine lesions (Fig. Lewis Divergence insufficiency patients are often symptomatic for diplopia and asthenopia at distance and may present with a decompensated distance phoria. Divergence fusion amplitude had been measured in most patients by first neutralizing their distance esotropia using a handheld loose prism. If you will recall, convergence insufficiency is the inability for one or both eye(s) to converge appropriately to a given target. This recommendation is based on the small size of the study population, the problems inherent in a retrospective investigation, and the grave consequences of failing to identify other neurologic signs. Therapists can make this activity more advanced by increasing the amount the, changing the target) or by using multiple, and making the patient look from one to another, , however instead of there being two different transparent image, that need to be fused into one, there is one image. To be enrolled in the study, patients had to meet the following 5 criteria: 1) relatively sudden onset of double vision at far vision, 2) no double vision at near vision, 3) high myopia >6.0 diopters (D) in both eyes, 4) no other neurological symptoms, and 5) a normal . Patients with 20 to 30 PDs of exotropia should be left with 10 to 15 PDs of residual vergence demand, and patients with a vertical strabismus of 3 to 10 PDs should be left with 2 to 4 PDs of residual vergence demand.7 RVD is best used in patients who have vergence ranges that have been maximally trained through vision therapy but still need prism to maintain binocular vision in free space.12. Divergence insufficiency - definition of divergence insufficiency by Divergence insufficiency is associated with systemic and neurological disorders, so we must rule out any underlying conditions that may be causing it. If the patient is still symptomatic, combining prism and vision therapy may help improve convergence and divergence ranges.

The most common symptoms are: Tired or sore eyes Blurry vision Double vision Headaches Trouble concentrating You may also have trouble reading. What is convergence spasm? This period included the duration of diplopia prior to the first evaluation in addition to the duration of diplopia until either resolution of it or until the last follow-up evaluation. Goldberg RDInternuclear ophthalmoplegia in giant cell arteritis. Objectives PDF CLINICAL SCIENCES Divergence Insufficiency Revisited - JAMA Scheiman M, Cotter S, Rouse M, et al. SEE RELATED: Binocular Vision Disorders: 6 Frequent Q&As Otherwise, neuroimaging can be deferred in patients with neurologically isolated divergence insufficiency, although careful follow-up is indicated to identify developing suspicious neurologic symptoms or signs. Some patients report double pictures, but when checked with the torch, only one light is seen. created image book. Head trauma 3. 8 (89%) had successful with postoperative vertical alignment and 4 (50%) were successfully corrected, with <5 of cyclotorsion postoperatively. These arguments do not preclude the possibility that some patients with comitant esotropia at distance and full-appearing ocular ductions might be suffering from sixth cranial nerve palsy, not divergence insufficiency. Clinical management of strabismus.

Primary divergence insufficiency is generally a benign condition. et al. In the 17 patients with primary divergence insufficiency who had adequate information to ascertain long-term follow-up, double vision persisted in 9 individuals. Some of the most common introductory exercises for vergence insufficiencies include Brock String, Barrel Cards, Stick-In-Straw, and Lifesaver cards. Divergence insufficiency is a rare ophthalmologic disorder manifesting itself among older adults. Reproduction in whole or in part without permission is prohibited. Other patients without known neurologic disorder (eg, midbrain metastasis) were referred to evaluate double vision. "The term divergence insufficiency implies a problem at the level of the brainstem, suggesting that there is decreased neural output to the extraocular muscles," said Prem S. Subramanian, MD, PhD, at the University of Colorado in Aurora. Ultimately, the diagnosis of DI, particularly in the primary form, tends to be elusive. Patients were categorized into 2 groups, primary (ie, neurologically isolated based on clinical criteria) and secondary (ie, associated with a neurologic or systemic disorder). Diplopia at Distance in Older Patients: Is It Sagging Eye Syndrome? During the total period of follow-up, none of the patients developed an alternative neurologic disorder. Patients with divergence insufficiency may complain of intermittent double vision (diplopia) when looking at something in the distance, frequent "wandering" of the eyes, headaches, motion sickness, and eye fatigue that comes and goes and can vary from day-to-day depending on how tired the individual is. Tamler Regardless of whether their underlying responsible disorder was established or not, additional neurologic symptoms and signs were readily apparent in all of these patients. Sagging Eye Syndrome. Clin Exp Optom. Recent trauma Br J Ophthalmol. Convergence and Divergence - Vivid Vision These conditions that affect convergence or divergence may cause symptoms such as seeing double at near or far while viewing an object. Any patient presenting with divergence insufficiency and neurological symptoms should undergo a full neurological evaluation and imaging. Many affected patients experience spontaneous resolution of double vision within several months. 133. HMDivergence paralysis following head trauma. Interestingly very little has been written on the mechanism of divergence insufficiency or frank paralysis in the above settings. Kerala J Ophthalmol. All rights reserved. Information obtained from direct telephone interviews with the patients and review of office records of referring physicians who continued to follow up some patients were included in the determination of follow-up.
