PURPOSE: To evaluate pattern collapse and torsional changes following vertical transposition of horizontal recti in patients with V-pattern exotropia and no oblique dysfunction. METHODS: A prospective study was performed on patients who had V-pattern exotropia and no oblique dysfunction. Lateral recti were transposed upward half-tendon width in V-pattern of 25 prism diopters (PD) or less (n = 14) and full-tendon width in V-pattern of greater than 25 PD (n = 10)...

PURPOSE: To review and analyze the surgical outcomes of bilateral medial rectus recession with adjustable suture in acute concomitant esotropia of adulthood (ACEA). METHODS: The charts of all adults diagnosed as having ACEA between 2004 and 2017 were reviewed. Best corrected visual acuity, refractive error, ocular alignment measured in prism diopters (PD), and stereopsis were examined at presentation, 1 day postoperatively, and final follow-up visit (median: 10 months; range: 4 to 144 months)...

PURPOSE: We report the first case of congenital ocular neuromyotonia (ONM) and the results of strabismus surgery for this patient's co-existing cranial nerve (CN) III palsy. PATIENTS AND METHOD: The patient presented at 18 months with strabismus that had reportedly been present since the time of birth. On exam, she had persistent exotropia (RXT) and hypertropia (RHT) with episodes of esotropia in the right eye that could be evoked by sustained left gaze. A diagnosis of ONM with partial CN III palsy was made...

Purpose: We evaluate a smartphone application (app) performing an automated photographic Hirschberg test for measurement of eye deviations. Methods: Three evaluation studies were conducted to measure eye deviations in the horizontal direction. First, gaze angles were measured with respect to the ground truth in nonstrabismic subjects ( n = 25) as they fixated monocularly on targets of known eccentricity covering an angular range of approximately ±13°. Second, phoria measurements with the app at near fixation (distance = 40 cm) were compared with the modified Thorington (MT) test in normally-sighted subjects ( n = 14)...

Purpose: The aim of this article is to study the feasibility of a delayed adjustable technique of strabismus surgery in children using an optional adjustable suture technique. Methods: The retrospective study included patients <12 years of age. Recessions were done using an optional adjustable bow-tie technique and resections were done by the conventional technique. Patients were evaluated on the third postoperative day and adjustments done when needed. Statistical analysis was done using Microsoft Excel 2010®...

PURPOSE: To describe outcomes after partial scleral buckle removal at the time of strabismus surgery. METHODS: The medical records of consecutive patients with symptomatic diplopia who underwent strabismus surgery after scleral buckling by two surgeons were reviewed retrospectively. All patients underwent forced duction testing and had a segment of the scleral buckle removed intraoperatively. Pre- and postoperative ocular motility and alignment were compared. The outcome was considered successful if residual horizontal deviation was ≤8Δ , vertical deviation ≤2Δ , and cyclotropia <5°...

INTRODUCTION: Bupivicaine has been shown to stimulate ocular muscle structure and length after injection into ocular muscles. Bupivicaine 0.75% has been utilized in the treatment of strabismus to alter ocular alignment by strengthening an ocular muscle. This study is designed to report 5-year follow-up outcomes after bupivicaine injection. METHODS: A retrospective chart review of all bupivicaine treated strabismus patients with symptomatic intermittent exotropia of the convergence insufficiency type (CIXT) from 2009 through 2016...

BACKGROUND: Convergence insufficiency (CI) is not an uncommon entity but seems to be an ill-defined diagnosis that incorporates many near-vision symptoms. The current literature often varies in its criteria for diagnosis. Without a clear definition and standardization of the clinical examination, there is the potential for misdiagnosis and/or the inclusion of other diagnoses as CI. The purpose of this study was to assess the uniformity of diagnostic criteria in a well-defined practice environment...

PURPOSE: To report long-term outcomes of strabismus surgery for treatment of third nerve palsy. METHODS: We performed a 15-year retrospective study of patients who had undergone surgery. We analyzed preoperative mean deviation (at 6 months, 1 year after surgery, and at the end of follow-up), type of surgery, and factors predicting outcomes. A final deviation <10 prism diopters (pd) was considered a good esthetic outcome, and no diplopia in the primary position at the end of follow-up was considered a good functional outcome...

OBJECTIVE: To present a report of the ocular motility disorders, treatment and outcomes of myasthenia gravis (MG). MATERIAL AND METHOD: A retrospective study was performed on the data of patients with MG. An evaluation was made using mean age, gender, initial diagnosis, ocular deviation, time of onset of clinical characteristics, treatment and results. Resolution of diplopia and/or ocular deviation in primary and reading gaze was considered a good outcome at the end of follow-up...

BACKGROUND: To compare clinical characteristics according to the laterality of objective ocular torsion in patients with unilateral superior oblique palsy (SOP). METHODS: This retrospective study included all patients with a diagnosis of unilateral SOP. They were classified into subgroups according to correspondence between the paretic eye and the extorted eye using fundus photography. Ocular alignment and muscle action were tested by the prism and alternate cover tests and 4-scale movement measure...

BACKGROUND: Previous techniques resulted with low rates of successful fusion after the surgeries and high necessity of additional surgeries in the treatment of thyroid orbitopathy related strabismus. In this study, reviewing the results of our patients who had surgical correction with relaxed muscle positioning technique due to thyroid orbitopathy related strabismus to evaluate the effectiveness of the surgery was aimed. METHODS: The medical records of 8 patients who had surgical correction with intraoperative relaxed muscle positioning (IRMP) technique were studied retrospectively...

We evaluated the effect of dichoptic visual training based on a unique virtual reality (VR) platform mounted display in patients with intermittent exotropia (IXT). A total of 25 IXT patients (8 men, 17 women) with a mean age of 12.3 years (range, 5-39 year) were recruited. The Hirschberg test, prism and alternate cover testing (with accommodative targets for fixation at 33 cm in all patients), perceptual eye position (PEP), and stereopsis were evaluated after 1, 3, and 6 months of dichoptic visual neuroplasticity training with a computer-controlled perceptual examination evaluation system...

PURPOSE: To examine stereopsis in patients with comitant horizontal strabismus who had normal vision and were stereoblind following the strabismus surgery. METHODS: Twenty patients with primary comitant horizontal strabismus and normal corrected visual acuity were included in this study.

PURPOSE: To describe a new surgical technique for the treatment of complete third nerve palsy. METHODS: This study included patients with chronic complete third nerve palsy. The lateral rectus muscle was split, followed by disinsertion of the superior and inferior halves, which were passed between the sclera and superior and inferior rectus muscles, respectively. Then the medial rectus muscle was sutured as posteriorly as possible from its insertion and cut. Next, the distal stump of the medial rectus muscle was split into two halves and united with the superior and inferior halves of the lateral rectus muscle...

PURPOSE: To determine the possible predictors of the motor outcome after corrective surgery for acquired comitant esotropia. METHODS: The study included 40 patients with acquired comitant esotropia. After evaluation of the visual, sensory, and motor status; cycloplegic refraction; fundus examination; and spectacle prescription, all patients underwent corrective strabismus surgery. A successful motor outcome was defined as 0 to 10 prism diopters of horizontal tropia...
