BACKGROUND The etiology of strabismus has a genetic component. Our study aimed to localize the candidate causative gene mutant in a Chinese family with strabismus and to describe its underlying etiology. MATERIAL AND METHODS Genomic DNA was extracted from the affected individual and his parents in a Chinese pedigree with strabismus. The resulting exomes were sequenced by whole-exome sequencing....

Background: Sore throat after endotracheal intubation during general anesthesia is a common complaint of patients especially in children. Strabismus surgery in one of the common procedures in child patients. The present study investigates the use of intratracheal ketamine administration in reducing sore throat after strabismus surgery. Methods: This study was performed on 60 patients undergoin...

The purpose of the study was to examine spatio-temporal characteristics of horizontal eye movements in the natural space (saccade, vergence and combined movements) in young subjects with early onset convergent or divergent strabismus. Nine young subjects (8-20 years old) were tested: three with divergent strabismus, six with convergent strabismus. A standard paradigm was used to elicit pure hor...

Competition between the two eyes for synaptic space is thought to play a crucial role in the developmental plasticity of ocular dominance in the primary visual cortex. This competition should be disrupted if geniculocortical afferents from the two eyes are spatially segregated. In kittens, strabismus was induced in one eye before the onset of the critical period; the effects of a brief period o...

BACKGROUND/AIMS Health-related quality of life (HRQoL) measures are used in healthcare to help inform clinical decision-making and policy-making decisions. A number of disease-specific or condition-specific measures have been developed and applied in ophthalmology; however, their use in the specific fields of amblyopia and strabismus are not as established. The purpose of this study is to ident...

OBJECTIVE To describe surgical strategies in a series of patients with diplopia following implantation of a glaucoma drainage device. METHODS Retrospective review of 9 consecutive patients who underwent strabismus surgery because of strabismus and diplopia after implantation of a glaucoma drainage device. RESULTS Seven patients with marked limitation to ocular rotations and incomitant strab...

The role played by the extraocular muscles (EOMs) in the etiology of concomitant infantile strabismus is still debated and it has not yet definitively established if the sensory anomalies in concomitant strabismus are a consequence or a primary cause of the deviation. The commonest theory supposes that most strabismus results from abnormal innervation of the EOMs, but the cause of this dysfunct...

BACKGROUND/AIMS Prematurely born infants are known to have an increased rate of ophthalmological morbidity. The aim of the present study was to investigate visual acuity and ocular alignment in a population of preterm infants in a geographical area, in infants with and without retinopathy of prematurity (ROP). METHODS A prospective population based study of ophthalmological status of preterm ...

We congratulate Yu et al. for their successful results where they evaluated the pattern distribution and the changes of strabismus surgery in pediatric population [1]. The authors observed that surgery for childhood exotropia was more common than surgery for esotropia in China and they stated that strabismus type and onset age were found to be associated with binocular function for subjects wit...

The American Association for Pediatric Ophthalmology and Strabismus (AAPOS) issued a 2021 update of Guidelines instrument-based vision screeners. Manufacturers need evidence to the Instrument Referral Criteria (IRC) in their devices.
