Retina & Vitreous Service
What is a retina: The retina is the third and inner coat of the eye which is a light-sensitive layer of tissue. Diseases of the retina, the vitreous, and the optic nerve can cause serious vision problems. Fortunately, most of them can now be managed satisfactorily with modern methods of diagnosis and treatment.

Vitreo retinal surgeries : If the vitreous is too clouded with blood or there is traction retinal detachment, laser treatment will not work. In this situation, a surgical procedure called VITRECTOMY needs to be performed.
LOSS OF VISION FROM DIABETIC RETINOPATHY IS LARGELY PREVENTABLE. Early Detection of diabetic retinopathy is the best protection against sight loss
