A condition in which the cornea thins and bulges forward is known as

Explanation:
Keratoconus is the condition described: the cornea thins and bulges forward into a cone shape, causing irregular astigmatism and distorted vision. This differs from glaucoma, which affects the optic nerve usually due to high eye pressure; cataract, which is clouding of the lens; and macular degeneration, which damages the central retina. Keratoconus often begins in adolescence or early adulthood and is managed with corrective lenses initially, with more advanced options like rigid contact lenses or treatments such as corneal cross-linking to slow progression, and in severe cases, corneal transplant.
