Visual Field Test Tips

Even something as small as an eyeball has multiple parts within it. The retina at the back of the eyeball is responsible for the clarity of vision. The central area of the retina is known as the macula. Macular degeneration is the deterioration of this part of the retina. Macular degeneration is age-related and considered an incurable condition. People suffering from macular degeneration experience blurred vision, black spots and may eventually lose central vision while retaining peripheral visi...more

Pupil dilation or dilated eyes simply mean a widening of the pupils. If you go for a comprehensive eye exam, your doctor will most probably conduct a dilated eye exam by using a special magnifying glass to observe the retina, optic nerve and the macula that is responsible for your normal vision clarity and colour vision.

How is it done?

The doctor will closely inspect each eye to detect any signs of common vision problems. He/she will put drops in each eye to widen the pupil (t...more

This is not a good practice since the best way to avoid severe eye complications is to detect them in their early stages. Since some eye conditions are asymptomatic in their early stages, these conditions cannot be detected without a compre...more

Clouding of normally transparent eye structures

Age-related macular degeneration, also known in brief as AMD or ARMD is one of the most common age-related causes for vision loss. It causes blind spots in vision, causing difficulty in activities requiring central vision like reading, sewing, driving, watching TV, computer usage, etc.

How it happens?

The centre portion of the eye is known as retina which has a screen in the posterior portion. For proper vision, light falls on this screen and is then processed to enable visi...more

While we usually consider the eye to be a single element, it does, in fact, have a number of smaller parts each which play a distinct role in helping us see. The retina covers more than half the interior surface of the eye and can be described as the light-sensitive layer that converts light into optic signals that are then carried to the brain. Retinal detachment is a serious condition that causes the retina to be separated from the supportive tissue. If not treated immediately, it could lead t...more

Retinal detachment is an emergency eye condition in which the retina at the back of the eye gets separated from the surrounding tissue and pulls away from its normal position. The retina acts as a light-sensitive wallpaper in the eye, providing a lining for the inside of the eyewall and sending visual signals to the brain. As the retina can't work properly under these conditions, one can permanently lose vision if the detached retina is not repaired immediately.

During the retinal detac...more

Most of the time it is harmless and does not create a problem. But, if a person is facing problems for more than three months in...more

A cataract is a clouding of the normally clear lens of your eye. For people who have cataracts, seeing through cloudy lenses is a bit like looking through a frosty or fogged-up window.

Clouded vision caused by cataracts can make it more difficult to read, drive a car (especially at night) or see the expression on a friend's face.

Most cataracts develop slowly and don't disturb your eyesight early on. But with time, cataracts will eventually interfere with your vision.
