Visual acuity assessment in diabetes.

Optometric or visual acuity assessment is an essential part of ophthalmologic examination. Visual acuity measurement serves as a tool for screening of ophthalmic disorders, as well as diagnosis and monitoring of refractive errors and other causes of reduced acuity. Persons with diabetes may experience situations which impair visual acuity, or which impact the utility of refractive visual acuity assessment.
