BACKGROUND Little is known about the aetiological factors underlying strabismus. We undertook a large cohort study to investigate perinatal risk factors for strabismus, overall and by subtype. METHODS Orthoptists reviewed ophthalmological records for Danish National Birth Cohort (DNBC) children examined for strabismus in hospital ophthalmology departments or by ophthalmologists in private pra...

IMPORTANCE In strabismus, the fixating eye conveys the direction of gaze while the fellow eye points at a peripheral location in space. The stability of the eyes may be reduced by the absence of a common target. OBJECTIVE To quantify the stability of eye position in strabismus and to measure variability in the ocular deviation. DESIGN, SETTING, AND PARTICIPANTS From 2010 to 2014, a prospect...

From a study of a large number of brothers and sisters suffering from concomitant squint, the following data were obtained: (1) 42-9% of the patients showed congenital strabismus. (2) In 96-5% of the sibs strabismus was of the same type. (3) The presence of a significant refractive error occurred in 82-8% of the patients. (4) In all twins strabismus appeared at the same age in both twins, and t...

Reports are conflicting on the presence of increased drift in amblyopic eyes. Furthermore, the individual effects of either amblyopia or strabismus alone on ocular drift have not been systematically investigated. We therefore used a photoelectric method to record horizontal eye position during monocular and binocular fixation in patients having amblyopia without strabismus, intermittent strabis...

Purpose. The Pediatric Vision Scanner (PVS) detects strabismus by identifying ocular fixation in both eyes simultaneously. This study was undertaken to assess the ability of the PVS to identify patients with amblyopia or strabismus, particularly anisometropic amblyopia with no measurable strabismus. Methods. The PVS test, administered from 40 cm and requiring 2.5 seconds of attention, generated...

Morning glory syndrome is a congenital optic disc anomaly in which much of the excavated colobomatous optic disc is filled with glial tissue. Ocular complications may include strabismus, reduced visual acuity and retinal detachment and it may have systemic associations as in Aicardi's syndrome. A patient with monocular morning glory syndrome and reduced visual acuity is reported. The pattern re...

We report a 6 year old male with a pattern of malformations and anomalies including intrauterine growth retardation, microcephaly, psychomotor retardation, a pattern of craniofacial anomalies (flat face, hypertelorism, epicanthic folds, strabismus, short nose, low set ears), hypospadias and cryptorchidism, bilateral partial cutaneous syndactyly between fingers 2 to 5 and toes 2 to 4, postaxial ...

PURPOSE To examine the effects of strabismic amblyopia and strabismus only, without amblyopia, on the temporal patterns of eye-hand coordination during both the planning and execution stages of visually-guided reaching. METHODS Forty-six adults (16 with strabismic amblyopia, 14 with strabismus only, and 16 visually normal) executed reach-to-touch movements toward targets presented randomly 5°...

OBJECTIVE To present strabismus data for premature infants with prethreshold retinopathy of prematurity (ROP) enrolled in the Early Treatment for Retinopathy of Prematurity study. DESIGN The prevalence of strabismus was tabulated for all of the infants with high-risk prethreshold disease who participated in the randomized trial of the Early Treatment for Retinopathy of Prematurity study and w...

OBJECTIVES To examine deficits in monocular and binocular vision in adults with amblyopia and to test the following 2 hypotheses: (1) Regardless of clinical subtype, the degree of impairment in binocular integration predicts the pattern of monocular acuity deficits. (2) Subjects who lack binocular integration exhibit the most severe interocular suppression. METHODS Seven subjects with anisome...
