Answer to Question 1

Ans:
C

Feedback:

Enlarging pituitary tumors can produce longitudinal damage through the optic chiasm with loss of medial fibers of the optic nerve representing both nasal retinas and both temporal visual half-fields. The loss of different half-fields in the two eyes is called a heteronymous loss. Metal fragments can get in the eye from welding. Hemorrhages in both eyes have numerous causes like uncontrolled hypertension and diabetes. Subarachnoid hemorrhages are usually trauma related.

Answer to Question 2

Ans:
A

Feedback:

Vitamin E, vitamin C (ascorbic acid), zinc, and beta carotene have shown promise at slowing the progression of the age-related macular degeneration in persons with the disease. Surgical options are not normally available for the dry variety of macular degeneration. Blood pressure control, cholesterol control, and cataract surgery are unlikely to be directly useful.
