For proper vision, eyes need to focus exactly on images. The two main determinants of refraction are focus power of cornea and the eye's axis length. In normal eyes, images are formed exactly on retina (emmetropia), but farsightedness (hyperopia) is the situation in which, the eye forms images in
Gyrate atrophy of the choroid and retina (GA) is a rare autosomal recessive chorioretinal degeneration characterized by myopia, cataract, varying degrees of night blindness, and progressive constriction of visual fields associated with chorioretinal atrophy resulting in blindness. The objectives of
