What condition is characterized by an increase in aqueous humor in the anterior chamber of the eye?

  1. Cataracts

  2. Glaucoma

  3. Macular degeneration

  4. Retinal detachment

The correct answer is: Glaucoma

Glaucoma is characterized by an increase in aqueous humor in the anterior chamber of the eye, which can lead to increased intraocular pressure. This condition arises when the drainage system for the aqueous humor becomes blocked or inefficient, preventing the normal outflow of fluid. The accumulation of aqueous humor can damage the optic nerve and potentially lead to vision loss if not managed appropriately. In contrast, cataracts involve the clouding of the lens of the eye, macular degeneration refers to the degeneration of the central portion of the retina, and retinal detachment involves the separation of the retina from the underlying tissue. None of these conditions are primarily associated with an increase in aqueous humor or the resultant intraocular pressure changes that define glaucoma.
