Diabetic Retinopathy and treatment options available to reduce the risk of vision loss from diabetes

DIABETIC RETINOPATHY

Diabetes is the leading cause of blindness. The most significant problem with diabetes is diabetic retinopathy, which in-turn damages the blood vessels of the retina which is like a screen where the image of objects we visualize falls.

SYMPTOMS

•          Blurred, double or distorted vision or difficulty in reading

•          Floaters or spots in your vision

•          Partial or total loss of vision or a shadow or veil across your field of vision

•          Pain, pressure or constant redness of the eye

TREATMENT PLAN

The choice of treatment depends on the stage of the disease, age of the patient and the recommendations of the ophthalmologist.

LASER PHOTOCOAGULATION

The most common line of action. But remember, this can only save the existing sight level and cannot make it better.

INTRAVITREAL INJECTIONS

Help patients with gross swelling in the macula. It may require eye injections in the form of vascular endothelial growth factor (VEGF) inhibitor drug or steroid to reduce the growth of abnormal blood vessels and leakage of fluid from them. Multiple injections may be required and help improve or stabilize vision.

VITRECTOMY

Vitreous hemorrhage can lead to a sudden loss of vision. If the vitreous hemorrhage is persistent then a procedure called vitrectomy is recommended. Many patients have improved vision after vitrectomy.

Regularretina screening is essential for all diabetics
