Injections into the eye, specifically into the vitreous or gel-filled cavity of the eye, are called intravitreal injections.

Anti-vascular endothelial growth factors (anti-VEGF) are probably the most commonly injected agents. They are used to treat wet age-related macular degeneration (ARMD), diabetic retinopathy, and retinal vein occlusion.

In these conditions, there are abnormal leaky blood vessels that cause fluid and blood to accumulate in and under the retina. This accumulation of fluid results in loss of central vision. The role of anti-VEGF agents is to shrink...

One of the most commonly asked questions in an eye exam comes right after the refraction, or glasses prescription check: “What is my vision?”

Almost invariably, people know the term “20/20”. In fact, it’s a measure of pride for many people. “My doctor says I have 20/20 vision.” Or, on the other side of that same coin, having vision that is less than 20/20, say 20/400, can be a cause of great concern and anxiety. In this discussion I will describe what these terms actually mean.

To lay the foundation, let’s discuss some common terms. Visual acuity (VA) is clarity or sharpness of vision. Vision can be measured both corrected (with glasses or contact lenses) and uncorrected...
