Purpose: To determine if the deviation angle changes in subjects with intermittent exotropia as they alternate fixation between the right and left eye in primary gaze. Methods: In this prospective observational cohort study, 37 subjects with intermittent exotropia were tested for evidence of incomitance. The position of each eye was recorded with a video tracker during fixation on a small central target. A cover-uncover test was performed by occluding one eye with a shutter that passed infrared light, allowing continuous tracking of both eyes...

PURPOSE: Familial clustering of common forms of primary strabismus like esotropia (ET) and exotropia (XT) is observed in a proportion of the strabismus cohort. The genetic components of this remain unidentified. Linkage studies have demonstrated susceptibility locus for primary strabismus at the STBMS1 locus on 7p22.1 as well as other loci on 4q28.3 and 7q31.2. Recently next generation sequencing (NGS) technology has emerged as a powerful tool in discovery genomics and a large number of novel disease-causing variants are being reported...

A 16-year-old girl presented with left eye large-angle exotropia. On examination, we found bilateral limitation of adduction. CT orbit showed hypoplastic medial rectus bilaterally, but intraoperatively we found absent medial recti on both sides. This case report explains discrepancy between the imaging and the intraoperative findings and discusses the management dilemma in view of the risk of anterior segment ischaemia and how marked exodeviation and adduction limitation was tackled by the new technique of transposition myopexy, a modification of the procedure described by Nishida along with recession of lateral rectus to achieve good alignment...

A 4-year-old girl presented with decreased vision since 3 months. Visual acuity was 20/20 in right eye and counting fingers at 2 meters in the left. Left eye examination revealed exotropia, retinal telangiectasia, extensive subretinal exudation over the macula and exudative retinal detachment suggestive of Coats' disease. Fundus fluoroscein angiography highlighted the hallmark 'light bulb' retinal telangiectasias, macular retinochoroidal anstamosis and peripheral nonperfused retina. The patient was treated with focal laser photocoagulation to the retinal telangiectatic vessels and scatter laser photocoagulation of the non-perfused retina...

We report the histopathological and ultrastructural tissue analysis of extraocular muscle (EOM) obtained from a patient with seronegative myasthenia gravis (MG) with treatment-resistant ophthalmoplegia for 3.5 years. The EOM demonstrated predominantly myopathic features and ultrastructural evidence of mitochondrial dysfunction, but the most striking features were increased endomysial collagen and adipocyte replacement of muscle fibers. By contrast, control EOM from a patient undergoing strabismus surgery for a sensory exotropia in a nonseeing eye and a similar duration of deviation, showed normal muscle histology...

PURPOSE: To compare long-term surgical outcomes after bilateral lateral rectus recession (BLR) and unilateral lateral rectus recession-medial rectus resection (RR) for the treatment of basic-type intermittent exotropia. METHODS: Consecutive patients who underwent BLR or RR for treatment of intermittent exotropia between 1999 and 2010 and underwent ≥5 years of follow-up were recruited for this study. Surgical outcomes were grouped according to postoperative angle of deviation: overcorrection (esophoria/tropia >8 prism diopters [Δ]), success (esophoria/tropia ≤8Δ to exophoria/tropia ≤8Δ), and undercorrection/recurrence (exophoria/tropia >8Δ)...

Various ocular and systemic reactions have been associated with insect sting. However, insect stings have been rarely reported to cause exotropia and diplopia. We encountered exotropia in a 6-year-old child with rhabdomyolysis of the left lower extremities caused by an insect sting. Exotropia and diplopia developed within 1 day after the sting and improved completely 1 week after the onset of symptoms. Clinicians should be aware of the potential for the development of exotropia in patients with insect stings, which requires careful follow-up...

PURPOSE: The hypothesis that the extraocular muscle insertion distance and muscle width may be associated with the type and size of deviation was tested. METHODS: This was a prospective study of 129 patients who had surgery for horizontal strabismus or retinal detachment. The insertion distances and widths of the medial rectus (MR) and lateral rectus (LR) muscles were measured intraoperatively in esotropia, exotropia, and buckling surgery (control group) patients...

We evaluated effect of horizontal rectus surgery on sub-A or sub-V pattern intermittent exotropia. We enrolled patients with sub-A or sub-V pattern intermittent exotropia. The sub-A pattern was diagnosed when the eyes diverged less than 10 prism diopters (PD) from upgaze to downgaze, and sub-V pattern when the divergence was 14 PD or less from downgaze to upgaze. Patients had undergone horizontal rectus surgery without vertical transposition of horizontal rectus muscle or oblique muscle weakening. The patients were divided into two groups: sub-A pattern (group A) and sub-V pattern (group V)...
