Solution

The correct option is A Increased pressure of fluid in eye ball
Glaucoma is caused by blockage of tiny ducts that drain the excess aqueous humor from anterior compartment of eyeball causing buildup of aqueous humor. This causes compression of the arteries that serve the nerve fibers of the retina due to increased pressure of aqueous humor. The death of nerve fibers due to lack of nutrients makes the person partially blind. Thus, the correct answer is option A.
