Retinal disease can take your vision slowly, and you may not notice until treatment is harder.

Find your condition below, read the symptoms and treatments, and book a free consultation with an interpreter.
In this guide
Macular degeneration
Macular degeneration damages the center of your retina, so reading and faces start to blur.
02Diabetic retinopathy
Long-term diabetes slowly damages the blood vessels in your eyes, often without early warning.
03Uveitis
Uveitis is inflammation inside the eye that can cause redness, pain, floaters and falling vision.
04Retinal detachment
Retinal detachment is an emergency: the retina lifts away from the eye wall and can cause blindness.
05Epiretinal membrane
An epiretinal membrane is a thin film on the retina that can bend straight lines and blur your sight.
06Retinal vascular disease
When a retinal artery or vein blocks, your vision can drop suddenly or blur.
07Glaucoma
Glaucoma damages the optic nerve and narrows your visual field, often without early symptoms.
Why early retina care matters
Retinal diseases cause gradual vision loss as the retinal nerves develop abnormalities. If your vision is already poor, you can miss the right time for treatment without knowing it. A retinal check finds problems early, when more options are open.
At Sky Eye Clinic, retina specialist Dr. Yu Hyeong-Gon sees patients directly. He is a former Seoul National University Hospital professor (2001 to 2022). You can read his credentials on the doctors page.

Three principles behind our retina care
- Consistent quality of care. We invest in medical technology and equipment dedicated to retina care, including OCT, wide-angle fundus imaging, VUNO Fundus AI and retinal laser equipment.
- Treatment for the patient, not for volume. We avoid unnecessary treatment and suggest the approach that fits each eye.
- Continuous improvement. We base our care on ongoing research and academic activity in eye health.
Our retina and vitrectomy tools include EVA Nexus vitrectomy equipment, EasyRet retinal laser, CLARUS and OPTOS wide-angle fundus imaging, and CIRRUS OCT 6000. Your doctor chooses the tests that match your symptoms.

- Retinal vascular disease: artery and vein occlusion, with sudden or blurred vision loss.
- Glaucoma treatment: optic nerve damage that narrows your visual field.
Warning signs that need a retinal exam
Retinal conditions often start quietly. See an eye doctor promptly if you notice any of the following.
- Floaters, or flashes of light like a camera flash
- A dark curtain across part of your vision
- Letters that look shaky or straight lines that look curved
- Sudden vision loss, even if temporary
- Gradually narrowing vision, or poor night vision
Sudden vision loss or a dark curtain in your sight can mean retinal detachment or vessel occlusion. Do not wait for it to pass.
