The Potential Acuity Meter is used to determine the potential acuity of a patient who has which condition?

• A. Glaucoma
• B. Cataracts
• C. Macular Degeneration
• D. Diabetic Retinopathy

Answer: (B)

Potential Acuity Meter is used when an eye has a media opacity, such as a cataract, to estimate the best possible vision after that opacity is removed. The device helps predict how well the patient could see postoperatively, guiding whether cataract extraction is likely to improve vision. In contrast, glaucoma, macular degeneration, or diabetic retinopathy affect the optic nerve or retina themselves rather than the clarity of the ocular media, so PAM wouldn’t provide a meaningful postoperative acuity estimate for those conditions.
