achromatopsia

Front 13

defective curvature of the cornea and lens, which causes light rays to focus unevenly over the retina rather than being focused on a single point, resulting in a distorted image

astigmatism

Front 14

degenerative disease in which the lens of the eye becomes progressively cloudy, causing decreased vision

Front 16

condition in which aqueous humor fails to drain properly and accumulates in the anterior chamber of the eye, causing elevated intraocular pressure
