4 Clinical Trials for Various Conditions
"GoCheck Kids" has added to its iPhone 7+ smart phone with flash concentrator a non-accommodating glow box fixation target. In pediatric eye patients, the "GCK" with glow box is compared to cycloplegic refraction as well as School Bus Accommodation-relaxing skiascopy, "2WIN" photoscreener and "Retinomax."
Photorefractive keratectomy (PRK) with excimer laser has been used successfully to treat myopia, hyperopia, and astigmatism in adults for over 35 years. Children with high refractive errors that go untreated will develop severe amblyopia. PRK can normalize high refractive errors and potentially improve the visual acuity in affected children. The purpose of this study is to investigate whether children with high anisometropia or isoametropia with amblyopia that are nonresponsive to standard therapy and receive PRK develop better longterm visual acuity.
The purpose of this study will be to: * Determine the amount of visual acuity improvement with treatment of presumed bilateral refractive amblyopia * Determine the time course of visual acuity improvement with treatment
The purpose for this study is to investigate spectacle compliance and treatment outcome in bilateral and unilateral refractive amblyopia in children age 3 to \<10 years old. Specifically, how frequently and for what duration is spectacle wear necessary to maximize best-corrected visual acuity by spectacle correction alone.
