The retina is the third and innermost layer of the eye that catches the light and helps us focus on things so that we can see clearly. This is one of the most important parts of the eye. The retina is made up of a number of light-sensitive cells that are connected to nerve fibres. These nerve fibres help in transmitting the images formed through neuro-impulses that reach the brain. There are many conditions and diseases that can affect this part of the eye.

Fortunately, with early diagnosis and treatment, more than 98% of chi...more

This can cause a number of symptoms including slight vision impairment and blurred vision as well as pain. The retina is a light sensitive part that can be found in the rear portion of the eye.

This part is responsible for sending visual signals to the brain which helps in forming the images that we see when we set our eyes on an object. If a pe...more
