Ulcers and perforations of the cornea are some very serious clinical conditions, which threaten vision rapidly and progressively and disintegrate the eye globe. They need to be taken care of immediately to prevent irreparable damage to the eyes. In spite of the advanced medical research and practice, severe injuries, infections, and diseases of cornea can lead to serious corneal perforations, which require surgery necessarily as the ultimate solution.

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

Anything that enters the eye from outside and causes inflammation or irritation, or even an abrasion, among varied other problems, can be termed as a foreign body. This foreign body usually ends up having an effect on the conjunctiva or the cornea. While the cornea is the outer layer that protects the eye, the conjunctiva is the membrane that covers the white portion of the eye. Here are a few ways for understanding and treating the entry of foreign objects into the eye.

Anterior most transparent layer of the eye is called cornea. It is an extremely useful layer for refraction and protection of the eye.

Any trauma, foreign body or chemical etc can invade the integrity of this layer and can be invaded by bacteria, fungus or virus, resulting in the corneal ulcer. Sometimes, due to hypoxia induced by contact lenses too can result in a corneal ulcer.

Depending on the clinical presentation, a doctor diagnoses the cause of the ulcer and start the the...more

Refraction is a test for an eye examination, which measures prescription for eyeglasses or contact lenses for individuals. The test can be performed by either an ophthalmologist or optometrist or in layman terms, an eye doctor.

Procedure for the test
In this test, the individual sits on a chair, which has a special device attached to it, called the refractor or phoropter. The individual has to look through the device and properly focus on an eye chart which is exactly 6 meters or 20...more

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.

Glaucoma is a disease that damages your eye's optic nerve. It usually happens when fluid builds up in the front part of your eye. That extra fluid increases the pressure in your eye, damaging the optic nerve. Glaucoma is the second largest cause of eye blindness in the world.

There are several types of Glaucoma:

Open-angle Glaucoma
Normal-tension Glaucoma
Angle-closure Glaucoma
Congenital Glaucoma
Secondary Glaucoma

The most common vision problems are shortsightedness and farsightedness. Shortsightedness is when a person sees close objects clearly while distant objects appear blurry. It is more common than farsightedness and affects about 70% of the Asian population.

When there is a refractive issue, the prescription usually has a plus/minus with it and also a number. A minus symbol is used to represent shortsightedness; the greater the number of the glasses, the higher the shortsightedness. High...more
