Active clinical trials for "Anisometropia"

Visual screening is necessary among pre-school children as they found themselves in a critical period of visual developement. To date, there are no national vision screening program that has been implemented nationwide. Vision is a pilot feasibility multicentric cluster study comparing the sensitivity of "AFSOP 3 dimensional visual screening protocol in a population of 3 to 4-year-old pre-school children conducted in 4 kindergarten preschools in Paris with gold-standard ophthalmic examination confirmation.

"Adaptica" (Padova, Italy) designed a fixed-distance, dark portable tube with power and remote control for the "2WIN: photoscreener. GoChecksKids designed a flash-concentrating case for the iPhone 7+ to more quickly achieve two-axis photoscreen. These devices were compared to confirmatory exams in children and young adults in a remote Burma clinic and in an Alaskan pediatric ophthalmology practice.

Population 1: Measure the effect of size glasses from1-9% on stereopsis Population 2: Measure the effect of size glasses from 1-9% on stereopsis in two settings: before and after cataract surgery after dilation of the eye

Our study has three parts has three parts, and the main aim of the study is to find out if corneal hysteresis was associated with myopia or even a predictor of myopia poor control predictor: Part 1 of our study: patients with anisomeropia whose spherical equivalent refraction as measured by cycloplegic autorefraction between the two eyes differ greater than 1.5 D. Part 2 of our study: Minus spherical equivalent refraction as measured by cycloplegic autorefraction. Part 3 of our study: patients with minus spherical equivalent refraction as measured by cycloplegic autorefraction who are under regular atropine for the treatment of myopia;patients who are prescribed with atropine treatment are in need of myopia control instead of for research interest
