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...

Strabismus is the misalignment of the eyes and is estimated to be present in ~2% to 4% of the North American infant population. Surprisingly, to date, there is no consensus regarding the cause of strabismus. While it is commonly thought to be the result of dysfunctional orbital and/or eye muscle properties (reviewed in Refs. 1, 2), recent work emphasizes that strabismus can also be caused by th...

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...

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...

BACKGROUND Strabismus and amblyopia are known to cause visual dysfunction, self-image disorders, difficulty in seeking employment and social and emotional barriers. These factors can have a serious and detrimental effect upon the patients' health-related quality of life (HRQOL). Presently, a condition-specific questionnaire is not available for assessing the HRQOL in Chinese patients. This stud...

Strabismus surgeons continually seek to achieve the best results from their surgery, which means stable motor alignment and sensory improvement with a minimum number of procedures. But the tables and algorithms that we employ for the number of muscles to be included in the surgery, and for the doses of surgery, are often not appropriate for difficult or unpredictable cases. The ability to modif...

From an analysis of the cases in the Strabismus Clinic in the New Haven Dispensary some facts are presented concerning: 1) the different types of squint; 2) amblyopia; 3) the incidence of surgical advisability; and 4) hypertropias. Muscle cases in the New Haven Dispensary were segregated into a special strabismus clinic, carried on in connection with the regular clinic, during 1933-34. The stra...

Objective: To translate and validate the Adult Strabismus Quality of Life Questionnaire into Brazilian Portuguese. Methods: A cross-sectional study for linguistic cross-cultural validation in order to assess quality life patients with strabismus. We have followed previous published guidelines on translation process ensure equivalence between original translated versions. The final version was a...
