✍️ Sample AOA Questions & Answers

1. Bitemporal hemianopia is most commonly caused by a lesion at which anatomical location?
Optic chiasm

Bitemporal hemianopia results from compression of the crossing nasal fibers at the optic chiasm, most often by a pituitary adenoma.

2. Which anti-VEGF agent is FDA-approved for neovascular (wet) AMD treatment by intravitreal injection?
Aflibercept (Eylea) and ranibizumab both approved

Both aflibercept (Eylea) and ranibizumab (Lucentis) are FDA-approved for neovascular AMD; bevacizumab is widely used off-label due to cost differences.

3. The ciliary muscle contraction during accommodation causes which change to the crystalline lens?
The lens becomes more convex as zonular tension decreases

When the ciliary muscle contracts, it moves anteriorly and inward, releasing zonular tension and allowing the elastic lens to assume a more spherical (convex) shape, increasing its power for near focus.

4. Topical antihistamine-mast cell stabilizer combinations (e.g., olopatadine) are first-line treatment for:
Allergic conjunctivitis

Dual-acting antihistamine/mast cell stabilizers like olopatadine block H1 receptors and prevent mast cell degranulation, providing rapid and sustained relief from allergic conjunctivitis symptoms.

5. Low vision rehabilitation is indicated when a patient's best-corrected visual acuity is:
20/70 or worse in the better eye with reduced functional ability

Low vision rehabilitation is appropriate for patients with best-corrected VA of 20/70 or worse that limits daily functioning and cannot be further improved by optical correction or treatment.

6. The vitreous humor is composed primarily of which substance?
Hyaluronic acid and collagen fibrils

The vitreous is approximately 99% water, with the structural framework provided by a network of hyaluronic acid (providing viscosity) and collagen fibrils (type II and IX).
