divergence insufficiency double vision

published a case series of long-term follow up for 29 patients with divergence insufficiency esotropia underwent lateral rectus resection. RDInternuclear ophthalmoplegia in giant cell arteritis. Diplopia following cataract surgery: a review of 150 patients Divergence fusion amplitude had been measured in most patients by first neutralizing their distance esotropia using a handheld loose prism. Concussion: Understanding Vision Problems Post-Injury - bocatc.org Ductions should be tested with the fellow eye covered. Divergence insufficiency can also result in headaches, motion sickness and sensitivity to bright lights. 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. No signs of orbital ischemia were present in the second patient. Accordingly, a patient with divergence insufficiency who has additional neurologic symptoms or signs should undergo a comprehensive neurologic evaluation that includes neuroimaging. In those patients without an established disorder, additional clinical clues indicated the need for neuroimaging or additional diagnostic studies, independent of the signs of divergence insufficiency. Chaudhuri Z, Demer JL. Actually it's not synonymous with divergence paralysis, but it is a separate clinical entity None of the patients initially classified as having primary divergence insufficiency developed additional neurologic dysfunction during the period of follow-up. They concluded that these surgeries are less effective for correcting cyclotorsion in patients with restriction or prior strabismus surgery.[14]. If the patient is still symptomatic, combining prism and vision therapy may help improve convergence and divergence ranges. Upon examination, she had a small exophoria and a 3 PD right hyperphoria at distance and near. Extraordinary symptoms equivalent to diplopia 2.3.1. Eye - Diplopia following cataract surgery . Divergence insufficiency is associated with systemic and neurological disorders, so we must rule out any underlying conditions that may be causing it. Sensory Anomalies. SHarbison The remainder of the neurological examination should be normal, without any cranial neuropathies. Vergence - Wikipedia AmblyoPlay is a vision therapy solution that is performed through playing therapeutic games and exercises on your tablet or computer for 30 minutes per day. J AAPOS. Divergence insufficiency is a rare ophthalmologic disorder manifesting itself among older adults. Bruce Divergence insufficiency revisited: natural history of idiopathic cases and neurologic associations. Her cover test revealed a 25 PD constant right esotropia with a 2 PD constant right hypotropia. 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. Primary and secondary forms exist, with the latter more urgently addressed due to neurologic comorbidities. 2016. The patient with divergence insufficiency presents himself complaining of double vision for distance, which increases with distance. Divergence Insufficiency: An Ongoing Challenge - Review of Ophthalmology 2012. Call our optometrists at 302-299-1286 or. Bender Audio blog post. Conclusions Reference: 1. Sagging Eye Syndrome. In some circumstances, individuals with convergence insufficiency will also suffer from high exophoria or exotropia, meaning the eyes like to sit in an outward position. Antireflective coating is also beneficial for patients wearing prism lenses. Six patients underwent CT and 10 underwent MRI. 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. 12. In addition, patients with SES usually have normal horizontal saccades and normal horizontal ductions. 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. reported a case series of 9 patients with vertical strabismus incomitant in horizontal gaze positions and cyclotorsion who underwent Adjustable small-incision selective tenotomy and plication. Another area of controversy concerns whether divergence insufficiency is a localizing sign referable to injury of a "divergence center," or is a nonlocalizing sign associated with a variety of focal and diffuse brain insults. Stern RVD states that esotropic patients of magnitude 6 to 20 PDs should be left with 4 to 6 PDs of residual vergence demand. These exercises were discussed in detail in Part 6 of this series. Of the 20 patients with primary divergence insufficiency, 19 (95%) were older than 50 years. More advanced exercises for vergence insufficiencies include Vectograms, Tranaglyphs, and Stereoscopes. Through her full plus spectacles, she still had a 14 PD constant right esotropia and a 2 PD constant right hypotropia. All patients with primary divergence insufficiency had been specifically asked whether their double vision was preceded by a specific event. Prism can be a powerful treatment for many conditions and for many patients, specifically for those who suffer from asthenopia or diplopia. Chaudhuri Z, Demer JL. 134.

Only 2 patients were followed up for less than 6 months. Sagging Eye Syndrome: Connective Tissue Involution as a Cause of Horizontal and Vertical Strabismus in Older Patients. RMTomsak From there, basic vergence exercises will be added in. If the patient is only using one eyethe image will not be formed correctly. What is convergence insufficiency? FEDivergence paresis: a nonlocalizing cause of diplopia. Patients will be able to work on fusing the images of one card and move on to a more difficult card as their fusional vergence ranges expand. Patients and methods. 13.119). Bothun ED, Archer SM. Patients with sagging eye syndrome can be treated surgically if they do not respond to or do not desire prism therapy. Beginning treatment, the patient suppressed on Worth Dot testing and had no RDS stereoacuity, even with corrective prism in place. Long-term follow-up and clinical features of the 2 groups were compared. Each card contains a partial view of the complete image. Convergence Insufficiency. Common symptoms include: headaches; blurred vision ; double vision Moore [5], MRI measurements of horizontal EOM lengths in SES were approximately 40%, or 14 mm, longer than the EOMs of nonstrabismic younger and older controls. Vision therapy exercises aimed at strengthening and normalizing accommodation can be found in Part 4 of this series. Nonparetic Diplopia - EyeWiki 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 . Divergence insufficiency is the opposite problem of convergence insufficiency. Lepore Randomised clinical trial of the effectiveness of base-in prism reading glasses versus placebo reading glasses for symptomatic convergence insufficiency in children. With one eye covered, the patient is able to move the open eye laterally and the pupil will dilate. Tamler 13.121). Divergence insufficiency patients are often symptomatic for diplopia and asthenopia at distance and may present with a decompensated distance phoria. Educating patients on the benefits of prism wear is key in helping get them on board in these cases. What lesion location is likely in the presence of horizontal conjugate deviation of the eyes to one side? The information below is from Neuro-ophthalmology Illustrated-2nd Edition. This distinction is especially problematic in patients with other neurologic signs, most importantly those associated with intracranial hypertension. What is convergence spasm? fine-tuned to work on strengthening either negative fusional vergence or positive fusional vergence. A recent review in January 2020 supported the evidence that when the symptoms of diplopia are burdensome to the patient, surgery is the only treatment that can eliminate the . When you try to focus on something close to your eyes, you may have: Tired eyes. HMDivergence paralysis following head trauma. Neuroimaging was not performed in 4 of these patients so it is possible that some of them had unsuspected lesions. Results: In high-myopia patients with divergence insufficiency, ocular axis measurements ranged from 24.8 to 31.0 (mean SD: 27.6 1.6) mm. The procedure is performed under topical anesthesia in the presence of an anesthesiologist. The clinical neurologic evaluation is a powerful tool that distinguishes those with a primary disorder from those harboring an underlying neurologic or systemic condition. The tool itself can be calibrated to work on increasing divergence or convergence, depending on what it is set to. 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]. The differential includes: It can be difficult to adjudicate small angle deviations such as HES and SES from mild myasthenia gravis, incompletely resolved sixth nerve palsy, thyroid eye disease, and decompensated prior phorias. Convergence Insufficiency/Vision Therapy - Eye Docs For Kids I prescribed 12 PDs base-out and 3 PDs vertical prism, split between her eyes. To register for email alerts, access free PDF, and more, Get unlimited access and a printable PDF ($40.00), 2023 American Medical Association. RMDiagnosis and management of divergence paresis. ALDemer As her vision improved with amblyopia treatment, I continued to monitor her sensory fusion. Once the two images have been combined into one, the patient will be asked to hold the image in place for 10-15 seconds. Then, a horizontal prism bar was used to place increasing strengths of base-in prism over the other eye until fusion could no longer be maintained, as assessed subjectively using a distant target for fixation. Her cycloplegic retinoscopy was +3.00sph OD and +2.25sph OS.

Divergence insufficiency patients are often symptomatic for diplopia and asthenopia at distance and may present with a decompensated distance phoria. These studies were unrevealing in all patients. Many patients were first evaluated within 1 month of the onset of symptoms, far sooner than the expected time course for the spread of comitance to convert a sixth cranial nerve palsy to a comitant esotropia. Divergence insufficiency associated with high myopia I trialed 2 PDs of base-down prism using a Fresnel prism over the right eye and dispensed at the initial visit. ARKline Simultaneous injury of the medial longitudinal fasciculus has been postulated as another reason sixth cranial nerve palsy may appear comitant.4 However, none of the patients classified as primary had clinical signs of internuclear ophthalmoplegia. It is usually benign. In a Tranaglyph, the amount of convergence or divergence needed to fuse the image is pre-determined, i.e. Strabismus. Pencil pushups may be effective in some cases. The SR was chosen when hypertropia was greatest in sursumversion or absent in infraversion. A stereoscope is a tool used to help expand fusional vergence ranges once a baseline has been established. What is divergence insufficiency? Ghanchi Primary divergence insufficiency is generally a benign condition. In many of these cases, the initial management strategy is prescribing vertical prism.1 Often, if the vertical deviation is decreased or eliminated, the patient may be able to comfortably fuse the horizontal deviation. 10. The characteristics of the patients in this series who have an idiopathic disorder suggest that if certain rules of diagnosis are obeyed, divergence insufficiency can be distinguished from sixth cranial nerve palsy in most cases using clinical techniques. Chamlin No clear sex predilection has been identified for the primary form of the condition. A Maddox rod was also used to determine the near point of orthophoria in most patients. . Corresponding author: Daniel M. Jacobson, MD, Neuro-ophthalmology (4F-2), Marshfield Clinic, 1000 N Oak Ave, Marshfield, WI 54449 (email: jacobsod@mfldclin.edu). To determine the natural history of primary divergence insufficiency and to identify clinical features that distinguish patients with this neurologically isolated form of divergence insufficiency from those harboring neurologic disorders. Divergence insufficiency is characterized as follows: Comitant esotropia is present at distance but not at near. The aspect of divergence paralysis or divergence insufficiency is stated as esotropia or high esophoria at a distance with much lower esophoria or near to normal fixation. The remaining 6 patients with secondary divergence insufficiency had symptoms and obvious signs of intracranial hypertension (eg, papilledema) (Table 2). Drs. Neuro-ophthalmology Illustrated-2nd Edition. If hypertropia persisted, further 5%10% increments of GVRT up to a maximum of 90% were added with monitoring of alignment. By continuing to use our site, or clicking "Continue," you are agreeing to our, Clinical Features of Patients With Primary and Secondary Divergence Insufficiency, Disorders Associated With Secondary Divergence Insufficiency. Randomized clinical trial of treatments for symptomatic convergence insufficiency in children. In that study, strabismus surgery was performed in 50% of all SES cases. Optom Vis Sci. Terms of Use| 2000;118(9):1237-41. Lateral rectus resections in divergence palsy: Results of long-term follow-up. This means the eyes do not like to move outward toward the ears and is problematic when trying to view a distant target. Supported by A person with divergence insufficiency may have double vision at a distance, which mainly occurs with severe exhaustion and fatigue. What is congenital ocular motor apraxia? Any patient presenting with divergence insufficiency and neurological symptoms should undergo a full neurological evaluation and imaging.2, Vision therapy aims to decrease symptoms of vergence anomalies by increasing the compensating fusional vergence range (base-in for esophoria and base-out for exophoria). [5] In addition, patients may have had eyelid surgery, face lifting,[6] or even apparently uncomplicated refractive or cataract surgery.[6][8]. CI affects children and adults. Once this can be repeated multiple times, the amount of required divergence or convergence can be increased, thus expanding the vergence range and strengthening the problem area. Define divergence insufficiency. Stager DR, Sr, Black T, Felius J. PDF Divergence Insufficiency - Jama Caloroso E, Rouse MW. All rights reserved. 128. Most trial lens sets come with prism lenses, but for larger angles of strabismus, it may be helpful to use a Fresnel prism trial set. 4 Binocular Vision Problems that Cause Eyestrain 134. Convergence describes the way our eyes move together and point inward when we look at near objects. Instead they turn their head briskly (head thrust) to shift fixation. Smooth pursuit and vertical eye movements are usually preserved. Eye movements are usually bilateral and symmetric in the horizontal plane. It is often idiopathic, but it has also been associated with several cerebral malformations and genetic disorders.Acquired Ocular Motor Apraxia Occurs in older children Associated with mostly metabolic disorders (Gaucher disease, ataxia-telangiectasia, spinocerebellar ataxias, NiemannPick disease) Convergence SpasmAlso called spasm of the near triad (Fig. 1993, Oxford, UK: Butterworth Heinemann Books. [5] Initially, most patients only notice intermittent binocular diplopia at long distances, such as in the theater or while driving. In many individuals with, Normalizing accommodation is important because. None of these patients underwent strabismus surgery. If you have not read the previous portions of the vision therapy series it is highly advisable that you check them out first as they cover basics not explained here. [1]SES should be differentiated from heavy eye syndrome (HES) which is an association of axial high myopia, esotropia, and hypotropia. These patients often present with horizontal and vertical deviations. use an approach called the SILO affect to work on increasing divergence or convergence ranges. Although no unsuspected neurologic disorder surfaced during the period of follow-up in these patients, I strongly recommend that a patient with isolated divergence insufficiency be followed closely to detect, for example, signs of developing intracranial hypertension or abducens nerve palsy. 132. Sagging eye syndrome (SES) was first described by Rutar and Demer in 2009, as a potential leading cause of strabismus in older adult population as a combination of horizontal and vertical strabismus in addition to bilateral blepharoptosis (ptosis with high lid creases) and deepening of the sulcus. Heavy Eye Syndrome in the Absence of High Myopia: A Connective Tissue Degeneration in Elderly Strabismic Patients. Intermittent convergence 2. with accommodation 3. pupillary constriction When the patient is asked to look to each side, the eyes do not move. They had experienced double vision for 5 weeks, 5 months, and 6 months, respectively, up to the time of their last evaluation, but did not return for further follow-up. Bothun and Archer reported a series of 8 patients who underwent bilateral medial rectus recessions for distance esotropias of 1235; 5 patients had satisfactory results with collapse of the distance-near deviation from 15 pre-operatively to 5 postoperatively. Divergence insufficiency is associated with systemic and neurological disorders, so we must rule out any underlying conditions that may be causing it. Theme, Congenital Ocular Motor Apraxia It affects young children. Defective or absence of voluntary horizontal saccades to visual stimuli: they cannot move their eyes horizontally to look at a target. None of these patients developed signs of an underlying neurologic disorder during follow-up. [15]Linear regression analysis of hypertropia correction with tenotomy showed that for a 36 hypertropia, a 3090% tenotomy is recommended. GNCurrent concepts in giant cell (temporal) arteritis. Thomson Relieving prism is often prescribed for patients with intermittent strabismus and sometimes for those with constant strabismus. With exercises that adapt to each patient and their specific needs, it is an ideal solution for problems such as lazy eye, strabismus, convergence insufficiency, double vision, or other binocular problems. Unilateral lateral rectus resection for horizontal diplopia in adults with divergence insufficiency. Heavy eye syndrome versus sagging eye syndrome in high myopia. GMOcular divergence: its physiology and pathology. The radiographic and laboratory evaluation of the 20 patients with primary divergence insufficiency did not reveal any unsuspected disorders. Keep moving to the next dot along the card, gradually getting closer to the nose. 2011;31(3):206-9. An affected patient experiences double vision when viewing distant objects, but not when viewing objects up close. Convergence and Divergence - Vivid Vision Other patients without known neurologic disorder (eg, midbrain metastasis) were referred to evaluate double vision. 8. Therefore, it forces the patient to use both eyes properly to see the image. J AAPOS. Weird vision divergence upon waking at night - Retirement -Social Her research interests include strabismus and binocular vision disorders. Patients who wear contact lenses the majority of the time or who have undergone refractive, cataract or strabismus surgery may not be happy with the idea of moving or going back to spectacle wear even if it relieves asthenopia or diplopia. Although the entity of divergence insufficiency was described as early as 1886 by Duane, it has received relatively little attention in the literature. AOcular divergence mechanisms. In high-myopia patients without double vision, the ocular axis length was 27.6 1.3 mm. . Magnetic resonance imaging did not identify hydrocephalus or involvement of the lesion along the anatomic course of the abducens nerve. While none of the patients had other symptoms to suggest giant cell arteritis or myasthenia gravis, erythrocyte sedimentation rate (performed in 7 patients) and acetylcholine receptor antibody assay (performed in 6 patients) were tested, and the results were normal in all. GTDJohnston 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. Symptoms resolved in 8 (40%) of 20 patients after a median of 5 months. make average daily distance tasks more manageable with less frequent symptoms. Convergence Insufficiency (CI): Symptoms, Diagnosis - Cleveland Clinic 2. American Academy of Ophthalmology. It is also stated that primary divergence insufficiency does not possess any other neurological symptoms as well as signs. 4. METraviesa Fresnel membrane prisms can be very useful for many aspects of prescribing prism. "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. 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. They include: double vision (diplopia) headaches blurry vision while reading squinting or closing one eye while reading words appearing to move around or float on the page while reading eyestrain or fatigue (asthenopia) Although prescribing it can seem intimidating at first, with practice and a bit of trial and error, you can perfect your ability to prescribe prism for your patients in no time. Only 1 of these patients, the one with a frontal lobe tumor, had a focal lesion. 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. Demer JL. In the 2 patients with temporal arteritis, the rapid resolution of esotropia coincident with initiation of corticosteroid treatment, along with the development of posterior ischemic optic neuropathy in 1 case, point to ischemic injury of extraocular muscles as the cause of ophthalmoplegia. It can also decrease distance judgement, coordination, and sports performance. Similarly, another dense band is found from the Superior rectus to the lateral rectus pulleys (LRSR band). Common symptoms include: headaches blurred vision double vision eye strain or fatigue sore or watery eyes after a near or far task American Academy of Ophthalmology. Patients will be able to work on fusing the images of one. In normal cases, the ocular axis length was 23.5 1.0 mm. Patients were categorized into 2 groups, primary (ie, neurologically isolated based on clinical criteria) and secondary (ie, associated with a neurologic or systemic disorder). Double vision is a troublesome complication of otherwise successful cataract surgery. ISOphthalmoplegia in cranial arteritis. [13]In their case series patients with lateral incomitance, the adjustable suture was generally placed on the MR opposite the horizontal direction of the greatest ET. Patel SH, Cunnane ME, Juliano AF, Vangel MG, Kazlas MA, Moonis G. Imaging appearance of the lateral rectus-superior rectus band in 100 consecutive patients without strabismus. Divergence Insufficiency Revisited: Natural History of Idiopathic Cases and Neurologic Associations. As a . . Clin Exp Optom. LMDivergence paralysis with increased intracranial pressure: further observations. Demer JL et al. These conditions that affect convergence or divergence may cause symptoms such as seeing double at near or far while viewing an object.
