From the Guidelines
To test for vision loss, a comprehensive eye examination with an optometrist or ophthalmologist is recommended, including visual acuity tests using an eye chart, such as the Snellen eye chart or the Early Treatment Diabetic Retinopathy Study (ETDRS) chart, as suggested by the US Preventive Services Task Force recommendation statement 1. The examination should also include peripheral vision tests, refraction assessment, and examination of eye structures using specialized equipment like a slit lamp. Some key points to consider when testing for vision loss include:
- The use of the pinhole test to detect refractive error, the Amsler grid to detect age-related macular degeneration (AMD), and fundoscopy to visualize the interior of the eye 1.
- Clinically significant cataracts can be visualized on physical examination as a change of color or opacities in the eye lens.
- Regular eye exams are crucial, especially for adults over 60 years or those with risk factors like diabetes or family history of eye disease, as early detection of vision problems can prevent permanent vision loss 1.
- The frequency of eye exams should be every 1-2 years for adults, and more frequently for those with risk factors.
- It is essential to seek professional care immediately if symptoms like blurry vision, difficulty seeing at night, seeing halos around lights, or sudden vision changes are noticed.
