BACKGROUND The purpose of this study was to evaluate the efficacy of a quantitative analysis method for comitant exotropia using video-oculography (VOG) with alternate cover. METHODS Thirty-four subjects with comitant exotropia were included. Two independent ophthalmologists measured the angle of ocular deviation using the alternate prism cover test (APCT). The video files and data of changes...

BACKGROUND Dissociated horizontal deviation is one of several conditions that manifest unequal horizontal deviations depending on which of the 2 eyes is fixating. PURPOSE To describe the reversed fixation test as an essential tool to establish the diagnosis of dissociated horizontal deviation. METHODS Analysis of 4 case scenarios depicting the utility of the reversed fixation test. RESULT...

An 11-year-old boy developed generalized tetanus complicated by a supranuclear gaze palsy and exotropia. This case led us to include supranuclear palsy in an expanded definition of cephalic-tetanus.

We report the effects of unilateral recession-resection surgery of the horizontal recti muscles with inferior displacement and augmented anterior transposition of the inferior oblique muscle with a posterior intermuscular suture in a patient with large exotropia and considerable hypertropia.

OBJECTIVE To report that maximum weakening of lateral rectus muscles can improve significant exotropia in primary position, abnormal head posture, retraction, narrowing of palpebral fissure and downshoot in exotropic duannes retraction syndrome. CASE A 12-year-old boy with exotropic Duane syndrome presented with downshoot and globe retraction in attempted adduction. Squint surgery was underta...

The aim of this study was to evaluate the efficacy of slanted recession of the lateral rectus muscle for intermittent exotropia with convergence insufficiency. This prospective study included 31 patients who underwent slanted lateral rectus recession for intermittent exotropia with convergence insufficiency between June 2010 and June 2012. Following parameters were recorded and analyzed: patien...

Partially accommodative esotropia is an acquired strabismus characterized by high hyperopia, a normal AC/A ratio, and a deviation that responds only partially to spectacle correction. Surgery is done for the non-accommodative portion of the deviation. Over-corrections are managed by reducing the hyperopic power of the spectacles. This retrospective study was done to determine the risk factors f...
