Diabetic Eye Disease (Retinopathy): symptoms, causes & treatment in Nigeria
Also known as diabetes eye problem.
This page is general health information, not a diagnosis. Always consult a licensed clinician about your own health.
Overview
Diabetic retinopathy is damage to the small blood vessels at the back of the eye caused by years of high blood sugar — a leading cause of blindness in working-age adults. It is silent until vision is already threatened, which is why every diabetic needs a dilated eye check at least yearly. Caught early, laser and injection treatments protect sight.
Symptoms
No symptoms in early stages
Gradual blurring of vision
Floating spots or cobweb-like shapes
Dark or empty patches in vision
Sudden vision loss from bleeding (advanced)
Difficulty reading or seeing detail
Causes & risk factors
Long duration of diabetes
Poorly controlled blood sugar
Uncontrolled blood pressure and cholesterol
Kidney disease and smoking accelerating damage
Pregnancy can worsen existing retinopathy
Treatment & self-care
Strict control of blood sugar and blood pressure slows the disease; eye specialists treat sight-threatening stages with laser or injections into the eye that preserve vision. A dilated retinal examination every year — even with perfect vision — is the safeguard. Sudden floaters or vision loss in a diabetic is an emergency.
See a doctor urgently if
Diabetic and no eye exam in the past year
New floaters, flashes or a curtain over vision — same day
Any drop in vision
Pregnant with diabetes (eyes need closer monitoring)
