AOA Low Vision and Geriatric Optometry 2

Question 1

A telescope is used as a low vision device to improve:

Accepted Answer

Distance visual acuity

Answer

Telescopes magnify distant objects and are prescribed to improve distance VA for activities like TV viewing, classroom use, and navigation in low vision patients.

Question 2

The most significant risk factor for falls in elderly low vision patients is:

Accepted Answer

Reduced contrast sensitivity and peripheral field loss

Answer

Contrast sensitivity loss impairs detection of steps and curbs, while peripheral field loss reduces obstacle detection — both are major fall risk factors in elderly patients.

Question 3

Electronic magnification devices (CCTV or video magnifiers) offer which advantage over optical magnifiers?

Accepted Answer

Variable magnification, enhanced contrast, and reverse polarity viewing

Answer

Video magnifiers allow continuous variable magnification, high-contrast display modes, and white-on-black reverse polarity, which optical magnifiers cannot provide.

Question 4

Pseudoexfoliation syndrome is associated with which significant systemic risk?

Accepted Answer

Cardiovascular disease and increased risk of myocardial infarction

Answer

Pseudoexfoliation syndrome is now recognized as a systemic fibrillopathy associated with elevated cardiovascular risk, including myocardial infarction and aortic aneurysm.

Question 5

A patient with moderate AMD and an absolute central scotoma should first be trained to use:

Accepted Answer

An eccentric viewing technique with a preferred retinal locus

Answer

When the fovea is destroyed, rehabilitation begins with identifying and training a stable PRL in the peri-central retina for fixation and visual tasks.
