PURPOSE To provide reference data for the measurement of ocular alignment and of angles of strabismus with a new stationary photographic apparatus at near and at distance fixation; to verify quantitative relations between the data by comparing experimental data with theoretical predictions. METHODS Use of Purkinje I and IV Reflection Pattern Evaluation in conjunction with a new stationary pho...

PURPOSE Structural abnormalities of extraocular muscles (EOMs) or their pulleys are associated with some forms of human strabismus. This experiment was conducted to investigate whether such abnormalities are associated with artificial or naturally occurring strabismus in monkeys. METHODS Binocular alignment and grating visual acuities were determined in 10 monkeys representing various species...

PURPOSE Abnormal torsion could be associated with cyclovertical strabismus, but torsion measurements are not reliable in children. To assess an objective fundus torsion evaluation in a paediatric population, we used Non-Mydriatic Fundus photography (NMFP) in healthy and cyclovertical strabismus patients to evaluate the disc-foveal angle over time and observers. METHODS We used a retrospective...

The goal of this study was to examine latency of horizontal eye movements in the natural space (saccades, vergence, and combined saccade-vergence movements) in children with early onset convergent or divergent strabismus. Ten children were tested (8-11 years old): three with divergent strabismus, seven with convergent strabismus. A paradigm was used to elicit pure lateral saccades at far and ne...

purpose: to report two sisters with congenital myasthenic syndrome (cms) masquerading as myasthenia gravis. patients and findings: two six and seven years old sisters presented with variable strabismus, ptosis, and fatigue. all symptoms were aggravated with exercise and improved with rest. intramuscular prostigmin injection decreased their symptoms. a diagnosis of cms was made according to earl...

Abstract Background To evaluate the distribution pattern and changes of strabismus surgery in northern China. Methods The records patients at Qingdao Eye Hospital from January 2014 to December 2019 were reviewed retrospectively. characteristics analyzed included gender, regional distribution, constituent ratio age type strabismus. Changes during periods 2014–2016 2017–2019 compared analyzed. Re...

AIM To describe the development and treatment of V-pattern and bilateral over-elevation in adduction in patients with cyclic esotropia. METHODS Three patients with cyclic esotropia are described in retrospect. All patients underwent bilateral medial recession, while one patient additionally had a weakening procedure of both inferior oblique muscles. RESULTS All patients developed a V-patter...
