Solution

The correct option is C
glaucoma

Glaucoma is an eye disease that causes vision loss if left untreated. Glaucoma happens when fluid inside the eye (aqueous humour) does not drain or isn't reabsorbed by the blood properly. This causes an increase of pressure in the eye and can damage eyesight. This defect can be rectified by performing a laser surgery.
