Guide To Diagnosing And Treating Cataracts

Retinal Exam

A patient's cataracts can be detected and diagnosed with a retinal exam or retinal imaging. A retinal exam allows an ophthalmologist or optometrist to see a patient's retina, blood vessels, and optic disk. The digital retinal imaging technique commonly used to carry out a retinal exam in modern-day medicine enables specialists to take a digital photo of the inside of a patient's eye. This photograph contains the macula, blood vessels, optic nerve, and retina. If signs of cataracts are present on a digital retinal imaging test, the ophthalmologist or optometrist will carry out the same test with the use of higher resolution and higher quality imaging referred to as fundus photography. Some characteristics of diseases that affect the eye may not be able to be seen with the use of a comprehensive eye exam with dilation. Certain subtle changes in the characteristics of a patient's eye can be seen better with the use of a digital retinal exam.
