Answer to Question 1

D
Glaucoma is a slowly progressing increase in intraocular pressure that causes pressure against the optic nerve, resulting in peripheral visual loss, decreased visual acuity with difficulty adapting to darkness, and a halo effect around lights if untreated. A cataract is a cloudy or opaque area in part of the lens or the entire lens that causes problems with glare and blurred vision. Diabetic retinopathy occurs when pathological changes occur in the retina, causing a decrease in vision.

Answer to Question 2

C
The sclera is the white part of the eye. The cornea is the anterior convex part of the eye.
Tears flow through the lacrimal duct.
