Retinologist: Who They Are, What They Do, and When to See One

You were told: "see a retinologist." It sounds serious, but it's actually simpler than it seems. A retinologist is a doctor who specializes in the retina: the thin light-sensitive membrane at the back of the eye that captures light and sends signals to the brain.

Retinologist: Who They Are

The retina covers about 72% of the inner surface of the eyeball, and its thickness at the thickest point is no more than 0.5 mm. This membrane is responsible for letting you see clearly both in dim light and in bright light. When something goes wrong in this thin structure, blurring, distortion, flashes, or missing areas of the visual field appear.

A retinologist is a doctor who can examine this specific area, recognize changes, and decide whether further testing or observation is needed.

How a Retinologist Differs from an Ophthalmologist

Retinal examinations are performed by eye specialists—referred to in English-language sources as eye care providers. They examine the fundus with dilated pupils and, if necessary, order additional tests.

What Retinal Diseases a Retinologist Detects

The range is broad. Common conditions affecting the retina include:

• age-related macular degeneration—breakdown of the central retina responsible for fine detail;
• diabetic retinopathy—damage to the small blood vessels of the retina in diabetes;
• retinal detachment and tears—emergencies;
• macular pucker and macular hole—scar tissue or a small defect in the center;
• retinitis pigmentosa—a hereditary group of disorders with loss of night and peripheral vision.

Risk factors for retinal diseases include diabetes, high blood pressure, smoking, eye trauma, and family history. Symptoms of retinal disorders may include blurred or distorted vision, loss of central or peripheral vision, flashes of light, floaters and threads, and difficulty seeing in the dark.

How a Fundus Examination Is Performed

First, the doctor instills drops that dilate the pupil, making the retina visible. Then they examine the fundus and assess the vessels, macula, and periphery to identify signs of damage.

What Tests a Retinologist Orders

In addition to a dilated-pupil examination, there are optical coherence tomography (OCT)—detailed images of the inner layers of the eye, fluorescein angiography to check retinal vessels, and visual field tests to assess peripheral vision. This is diagnostics, not treatment: based on the results, the doctor decides what to do next.

When a Retinologist Consultation Is Needed

Reasons include suddenly appearing or sharply increasing "floaters," flashes of light, a dark "curtain" or shadow in the visual field, or sudden blurring. With such symptoms, you need to seek help quickly: retinal detachment requires treatment within a short time frame to avoid permanent vision loss. If you smoke, have diabetes or high blood pressure, have had eye trauma, or have a family history of retinal diseases, regular eye examinations are useful.

This alone is not a reason to call an ambulance; 103 or 112—if vision has dropped sharply, a dense dark curtain has appeared before the eye, or flashes and "floaters" have arisen suddenly and in a flood.
