Question

Mr. Gregory is a 62-year-old African-American male. In his youth he was an amateur boxer. He hadn't been to a doctor in over 10 years, but he's decided to make and appointment with an ophthalmologist. More and more he's losing his peripheral vision. There are no other symptoms; he just can't see as well as before. The doctor tested Mr.s Gregory and found his intraocular pressure (IOP) to be increased (normal: 12-22 mmHg). Based on Mr. Gregory's signs/symptoms, what is his most probable diagnosis? How did the doctor evaluate his IOP?

	a.	acute angle-closure glaucoma; tonometry
	b.	chronic open-angle glaucoma; tonometry
	c.	cataract; ophthalmoscopy with eye dilation
	d.	macular degeneration; fluorescein angiography

Answer 1

Chronic glaucoma, also known as primary open-angle glaucoma or POAG, is sometimes called "the silent thief of sight" because in the early stages of the disease there are no warning signs — no pain or vision loss or other hints that something is wrong.
