Retinal Diseases

 Vitreo-Retinal Services

The eye is like a camera with a lens in front and a film (retina) at the back. The cornea and lens in the front of the eye focus the rays of light onto the retina which then converts the image into electrical signals that are sent to the brain through the optic nerve.

The retina is a thin sheet of tissue which lines 2/3rds of the back of the eye. Fibers from all over the retina join to form the optic nerve which is in the center of the retina.

Parts of the eye are the Retina and Vitreous

The eye is like a camera with a lens in front and a film (retina) at the back. The cornea and lens in the front of the eye focus the rays of light onto the retina which then converts the image into electrical signals that are sent to the brain through the optic nerve.

The retina is a thin sheet of tissue which lines 2/3rds of the back of the eye. Fibers from all over the retina join to form the optic nerve which is in the center of the retina. A little to one side of the optic nerve is the main part of the retina called the macula. The macula is a very small area but is responsible for the detailed, central vision that we have (i.e. reading, writing, recognizing faces, seeing the watch, mobile numbers etc. The rest of the retina gives us peripheral vision essential for walking and driving.

The vitreous is the clear jelly like substance that fills the eye- from the lens in the front to the retina at the back. Its function is not well defined. With age it undergoes degeneration, liquefies and shrinks in size. As it occupies less space it cannot fill the entire eye and detaches from the retina posteriorly.

There are common Vitreo-Retinal diseases

The common Vitreo-retinal diseases seen are:

    Diabetic Retinopathy
    Occlusions of the Retinal Veins
    Age Related Macular Degeneration
    Retinal Detachment
    Myopic Retinal Degeneration
    Floaters / Posterior Vitreous Detachment

Diabetic Retinopathy

Diabetic retinopathy (DR) is a disorder of the small blood vessels of the retina (Angiopathy) as a result of prolonged high blood sugars. It is part of the Angiopathy occurring in the entire body that results in the other complications of diabetes such as kidney problems (Nephropathy), nerve problems (Neuropathy) and several others. When severe it can result in blindness.
