Question

Glaucoma is due to

• A. Blocking of canal of Schlemm
• B. Drying up of vitreous humor
• C. Increased size of eye
• D. Opacity of lens

Answer 1

The correct option is A Blocking of canal of Schlemm

Glaucoma is a disorder of eye in which the optic nerve is damaged and this leads to blindness. It occurs due to increase in pressure of eye (intraocular pressure) when a fluid is built up in the front part of eye. The fluid builds up when it fails to get drained out due to blockage of canal of Schlemn. Canal of Schlemn is a circular canal that lies at the junction of sclera and cornea, through which excess aqueous humour is drained out from the anterior chamber.

So, the correct answer is 'Blocking of canal of Schlemn'.
