Strabismus is a condition in which the two eyes are not parallel but one is deviated with respect to the other, horizontally and/or vertically. The cause of childhood strabismus is generally unknown, although weakness of one or several of the eye muscles may be present as will be shown in the case presentation below. The most common type of strabismus, without any obvious dysfunction of the eye...

The causes of manifest (strabismus) and latent (phoria) misalignment of the visual axes are incompletely understood. We calculated genetic and environmental contributions to strabismus based upon a critical review and quantitative meta-analysis of previous strabismus twin studies (n=3418 twin pairs) and calculated contributions to phoria based upon a new twin study (n=307 twin pairs). Our resul...

Purpose: To study the prevalence, characteristics, indications for and results of strabismus treatment secondary to congenital cataracts. Materials and methods: This was a retrospective study of 21 cases from 29 with congenital cataracts with strabismus (unilateral in 11 and bilateral in 10 cases). In 20 patients surgery on the cataracts was performed, with an intraocular lens inserted in 15 pa...

OBJECTIVE To assess whether outcomes of strabismus surgery are improved by using the adjustable suture technique and to determine which subgroups of strabismus patients benefit most from the adjustable suture technique. DESIGN A retrospective chart review. PARTICIPANTS A total of 535 adults who underwent strabismus surgery between 1989 and 2010. METHODS Success was defined as ≤10 prism di...

BACKGROUND The impact of strabismus on visual function, self-image, self-esteem, and social interactions might decrease health-related quality of life (HRQoL). This study aimed to evaluate the psychometric properties and clinical applications of two strabismus-specific HRQoL questionnaires in the cultural context of China. METHODS The Chinese versions of the Adult Strabismus Quality of Life Q...

PURPOSE OF REVIEW This review includes updated information regarding adjustable suture strabismus surgery for children and adults. RECENT FINDINGS Main themes in the literature reviewed in this article include the appropriate timing for the adjustment technique, appropriate anesthesia, recent modifications in adjustable strabismus surgery techniques, and future developments. SUMMARY Improve...

Purpose: To investigate the clinical significance of ocular torsion in children by analyzing associated ophthalmic diseases.Methods: Fundus images were used to detect one or both eyes 83 aged 2-12 years at a pediatric ophthalmology clinic. In cases with torsion, diseases, including strabismus, amblyopia, and refractive errors, investigated.Results: Among patients, 59 (71.2%) 45 (54.2%) had stra...

Strabismus is one of the common vision disorders. For people with mild strabismus, many evidences showed that doing eye muscle exercise would be very helpful to straighten the weak eyes and improve eye performance eventually. In this paper, we propose aneye-trackingaided training system for strabismus therapy. We aim at helping strabismus people train eye muscle movements with a real-time train...

Age related binocular vision disorders (age related strabismus) could include all types of spontaneous strabismus appearing along the lifetime, which are directly connected with the aging process. Neurological strabismus is excluded. Functional and structural changes related to the aging process can induce phoria decompensation, convergence insufficiency decompensation and new onset strabismus ...
