In celebration of World Retina Week, it is important that we know more about the retina and find out the disorders that can affect the retina and possibly result in permanent loss of sight (blindness).

The retina is a thin layer of tissue found at the back of the eye on the inside. It is near the optic nerve. Its function is to receive light from objects that the lens has focused on, then send the light signals to the brain. The brain then decides what the picture is, which results in our ability to identify and recognise the images or objects that our eyes see. The retina is responsible for the sharp, central vision required for seeing fine details, driving and reading.

There are several retina problems and diseases which can affect the human vision. Here are some of them.

Macular degeneration.

It is the most common serious, age-related eye disease which destroys the sharp central vision of the eye.

Diabetic retinopathy

This is a retinal disease that occurs because of the effect of diabetes on the eyes. It causes damage to the blood vessels which supply the nourishment needed by the retina, thus resulting in significant loss of sight.

Hypertensive retinopathy

Serious high blood pressure can also damage the blood vessels that nourish the retina, resulting in severe vision problems. Those at risk of having this disease include individuals with obesity, stress, excessive salt consumption and lack of exercise.

Retinal detachment

This is a situation whereby the retina is pulled away from the layer of the eye where it gets nourishment. This is a severe medical emergency that requires immediate reattachment of the retina. Otherwise, it would cause permanent damage to the affected area leading to complete vision loss.


Individuals of all ages in the family should get routine and regular eye checks. This would help with early detection and treatment of eye diseases, thus preventing otherwise avoidable permanent damage to the eyes. Contact us for more information on treatment and care of the retina.
