Diabetic Retinopathy
What is Diabetic Retinopathy?
Diabetic retinopathy is a complication of diabetes that damages blood vessels inside the retina at the back of the eye. This damage can cause leakage of blood and/or fluid in the macula (macula oedema), abnormal blood vessel growth and restricted blood supply to the retina. People with Type 1, Type 2 or gestational (during pregnancy) diabetes are at risk.
Symptoms of Diabetic Retinopathy
Initially, you may not notice changes in vision even though you may have the early stages of diabetic retinopathy. However, as the diseases progresses you may start to notice:
- General reduction/blurriness in vision, one or both eyes
- Increased or new onset of floaters
- Having a dark or empty spot in part of your overall visual field
- Difficulty seeing well at night
Treatment options for Diabetic Retinopathy
Depending on the severity of diabetic retinopathy, different treatment options are available.
- Retinal laser therapy can be performed to shrink the abnormal blood vessel growth and prevent further bleeding or leaking
- Anti-VEGF injections to the eye to reduce macula oedema by blocking the production of the VEGF protein by the retina, thereby stopping the cycle abnormal blood vessel growth and fluid leakage
- Vitrectomy surgery if there is severe bleeding in the retina whereby the ophthalmologist will remove the vitreous gel (jelly-like substance that fills your eye) which is being clouded by blood
