Harindersingh Sethi, Mayuresh Naik, Mukesh Joshi
The measurement of the amount and nature of deviation is the essence of diagnostic workup of a patient with strabismus and also has important therapeutic implications while planning the amount of surgery or prescribing therapeutic prisms. Although Krimsky test is a useful method, it cannot be used to measure deviation in patients with scarred and irregular cornea with an anechoic posterior segment making it difficult to see the corneal reflex. We hereby take the opportunity to present a modification of the original Krimsky test which is extremely helpful in determining the deviation in patients with irregular opaque corneas...

Purpose: Strabismus correction surgery is well documented in both the literature and practice with varying levels of success and permanence. Our goal was to characterize longitudinal changes in eye alignment and eye movements following strabismus correction surgery in a monkey model for developmental strabismus. Methods: We studied two juvenile rhesus monkeys with exotropia previously induced via an optical prism-rearing paradigm in infancy. Eye misalignment was corrected via a resection-recession surgery of the horizontal rectus muscles of one eye...

PURPOSE: Patching for double vision is a common palliative treatment for head-trauma patients with acquired strabismus when prisms are not feasible. METHODS: We review literature on spatial neglect and discuss possible effects of monocular occlusion on spatial attention. RESULTS: Patching the left eye has been shown to worsen spatial judgments in some brain-injured patients with left neglect by inhibiting the right superior colliculus further impairing contralateral leftward orienting (the Sprague Effect)...

INTRODUCTION: Acute acquired distance esotropia (AADE) is a poorly understood moderate-angle strabismus, affecting young adult myopes and determining bothersome diplopia. Symptoms can be intermittent in the early stages, becoming constant in long-lasting disease. Symptomatic therapy includes prism correction, while surgery is the only curative treatment. However, the latter is affected by high rate of symptoms recurrence with the frequent need for reoperation. HYPOTHESIS: We hypothesize that AADE could be caused by the increase of the accommodative demand, often secondary to a myopic overcorrection...

The major goal of extraocular muscle surgery for nystagmus is to reduce the abnormal head turn (AHT) which is caused by an eccentric null zone of the nystagmus. Shifting the null zone to the primary gaze position will eliminate the AHT. The Kestenbaum procedure consists of bilateral recession of the yoke muscles opposite to the AHT, combined with bilateral resection or plication of their antagonists. The Anderson procedure is confined to bilateral recession of the yoke muscles and is therefore less invasive...

AIM: To assess strabismus control and motor ocular alignment for basic exotropia surgery at 5y follow-up. METHODS: The medical records of 80 consecutive patients aged less than 17 years of age, who underwent surgery for basic exotropia by a single surgeon between years 2000 to 2009 and completed a minimum of 5y follow-up post-operatively were reviewed. Pre- and post-operative characteristics were documented at 1wk, 6mo, 1, 3 and 5y follow-up. Subjects at 5-year follow-up were assigned to the success group if they had a post-operative angle of deviation within 10 prism diopters of exotropia or within 5 prism diopters of esotropia for distance on prism cover test, and had moderate to good strabismus control...

The purpose of this study was to evaluate the reliability of the fixation preference testing with 10 and 20 diopter prisms ((Δ)) in children without strabismus in order to extrapolate its utility to preverbal children and to determine interexaminer agreement. Fourty children (24 girls, 16 boys) aged between 5 and 16 years with normal ophthalmological examination except refractive errors were included in the study. The visual acuity, refractive errors, and orthoptic findings were recorded. The base-down prism fixation test was performed by two experienced examiners with 10(Δ) and 20(Δ)...

INTRODUCTION: Surgical rehabilitation of thyroid orbitopathy involves reducing proptosis, treating strabismus, lengthening the eyelids, and managing aesthetic changes. Not all are necessary in each patient; however, they often are. The current investigation intends to describe postdecompression changes that may influence the staging of these procedures. METHODS: In this retrospective cohort study, records of 169 patients who underwent orbital decompression between 1983 and 2001 were reviewed...

BACKGROUND: Cyclic strabismus is a very rare condition of ocular motility characterized by alternating strabismus and orthotropia. We report a patient with a 48-h cycle of vertical deviation associated with dysthyroid ophthalmopathy that spontaneously resolved. CASE PRESENTATION: A 40-year-old woman experienced sudden onset vertical double vision. She had already been diagnosed with hyperthyroidism. Asymmetric enlargement of the inferior and medial rectus muscles was demonstrated in her left eye on computed tomography, and was compatible with dysthyroid ophthalmopathy...
