Question 1

A patient with primary open-angle glaucoma on maximum tolerated medical therapy continues to show progressive visual field loss. What is the most appropriate next step in management?

Question 2

Which class of glaucoma medications works by decreasing aqueous humor production through inhibition of carbonic anhydrase?

Accepted Answer

Dorzolamide

Answer

Laser peripheral iridotomy is the definitive treatment for acute angle-closure glaucoma to prevent recurrence.

Question 4

Which visual field defect is most characteristic of early glaucomatous damage?

Accepted Answer

Nasal step

Answer

A nasal step, where there is a difference in sensitivity across the horizontal midline nasally, is a classic early glaucomatous field defect.

Question 5

What is the primary mechanism of action of selective laser trabeculoplasty (SLT) in lowering intraocular pressure?

Accepted Answer
