Question: What is fundus photography, and why do I need a photo of the back of my eye if I feel normal?
General Eye Health
Answer: Fundus photography is a detailed photo of the retina, optic nerve, and blood vessels at the back of the eye. These structures are extremely important because they can show signs of diabetes, high blood pressure, glaucoma, retinal degeneration, and other diseases. Even if you feel normal, these conditions may already be developing silently. The photo also allows future comparison over time.
