Assessment of Stereoacuity in Patients with Strabismus
… To analyze the stereoacuity in patients with strabismus using various stereotests. METHODS: Stereoacuity was assessed in children diagnosed as intermittent exotropia or refractive accommodative esotropia using Titmus stereotest, TNO stereotest, and Lang stereotest. Patients with amblyopia or …

Development of the ocular motor system in mouse embryos
… development in the ocular system leads to strabismus, amblyopia, and impaired vision. Strabismus alone affects up to 2% of the population, and studies have shown that it greatly affects self-image, employment, and public perception. Studying the development of the ocular motor system can …

Growth factors in extraocular muscles: effects on contractile properties
… extraocular muscles are imbalanced, this causes strabismus, which is an urgent situation in infancy because it disrupts the development of normal neurovisual circuits and binocular vision. In this dissertation, I examined the effects of three growth factors, IGF1 (Insulin-like Growth Factor 1), …

Neuromuscular junction formation in Extraocular muscles of embryonic mice
… disorders result. One of these disorders is strabismus, a misalignment of the eyes. Despite the importance of the oculomotor system, little is known about the migration and innervation of extraocular muscles embryonically in mice. When a nerve innervates a muscle, a chemical synapse, referred …
