What Is the Retina?
The retina is the light-sensitive layer of tissue lining the back of your eye. It contains millions of photoreceptors (rods and cones) that convert light into electrical signals sent to the brain via the optic nerve. Without a healthy retina, clear vision is impossible.
Common Retinal Conditions
Diabetic Retinopathy
High blood sugar damages the tiny blood vessels in the retina. In advanced stages, new fragile vessels grow and bleed into the eye, causing severe vision loss. Annual eye exams are essential for all diabetic patients.
Age-Related Macular Degeneration (AMD)
AMD affects the macula — the central part of the retina responsible for sharp, detailed vision. Dry AMD progresses slowly; wet AMD can cause rapid vision loss if untreated.
Retinal Detachment
When the retina separates from the tissue beneath it, it is a medical emergency. Warning signs include a sudden increase in floaters, flashes of light, or a shadow across your visual field.
Retinal Vein Occlusion
A blockage in the retinal vein restricts blood flow and can cause sudden blurred or lost vision. Risk factors include high blood pressure, diabetes, and high cholesterol.
Warning Signs — See Us Immediately If You Notice:
- Sudden increase in floaters (dark spots or strings)
- Flashes of light (especially in peripheral vision)
- A curtain or shadow across part of your vision
- Sudden blurred or distorted central vision
Modern Treatment Options
| Condition | Treatment |
|---|---|
| Wet AMD | Anti-VEGF injections (ranibizumab, aflibercept) |
| Diabetic retinopathy | Laser photocoagulation, anti-VEGF, vitrectomy |
| Retinal detachment | Pneumatic retinopexy, scleral buckle, vitrectomy |
| Retinal vein occlusion | Anti-VEGF injections, corticosteroids |
Early Detection Is Everything
Many retinal diseases cause no symptoms until significant damage has occurred. Our state-of-the-art imaging technology — including optical coherence tomography (OCT) and fundus photography — can detect subtle retinal changes years before symptoms appear.
