Diabetic Retinopathy

Diabetic Retinopathy

Diabetic retinopathy is a common diabetic eye disease - it damages the retinal blood vessels and causes vision loss. Diabetic retinopathy may cause the retinal blood vessels to swell, or cause fluid leakage. In other circumstances, this disease can cause abnormal blood vessels to grow.

Diabetic retinopathy normally does not have any early symptoms. But if this disease worsens, it poses severe risks. The severe symptoms may include: bleeding, swelling or macular edema.

Diabetes (Type 1 and Type 2) are the main causes. Detailed eye exams (e.g. visual acuity, pupil dilation, ophthalmoscopy) can often detect this disease. Laser surgery can be used to treat severe macular edema or proliferative retinopathy.
