Final answer:
Long-term blockage of the canal of Schlemm can induce glaucoma, a condition characterized by a buildup of fluid in the lens of the eye.
Step-by-step explanation:
Long-term blockage of the canal of Schlemm can induce glaucoma, not cataracts, macular degeneration, or retinal detachment.
Glaucoma is a condition in which there is a buildup of fluid in the lens of the eye, resulting in an enlargement of the eye. It can be treated with medication such as 'acetazolamide'.
Intraocular pressure, which is the fluid pressure in the eye, is responsible for maintaining the shape of the eye. When the circulation of fluid in the eye is blocked, it leads to a buildup in pressure and the development of glaucoma.
