Measuring visual acuity with a potential acuity meter is useful for patients with

1. Glaucoma

2. Diabetic retinopathy

3. Cataracts

4. Macular degeneration

The correct answer is: Cataracts

Measuring visual acuity with a potential acuity meter is especially useful for patients with cataracts. This tool helps assess the potential visual acuity that a patient could achieve post-cataract surgery. Cataracts can cause significant visual impairment by clouding the natural lens of the eye, leading to blurry or dim vision. By using a potential acuity meter, eye care professionals can estimate the level of improvement in visual acuity that may be achievable with cataract surgery, aiding in surgical decision-making and patient counseling. Glaucoma, diabetic retinopathy, and macular degeneration may affect visual acuity but are generally not conditions where a potential acuity meter would be the primary tool used for assessment and management.
