Retinal Eye Disorders Tips

Keratoconus is the thinning and bulging of the cornea due to weakening of the bonds between the collagen layers in its structure. The normally round cornea becomes thin and cone-shaped, and bulges out, deflecting the light entering the eye leading to a distorted and blurry vision. While it has a genetic tendency in some instances, it can also be produced by vigorous and long term eye rubbing especially in people with chronic eye allergy.

The diagnosis is suspected on clinical examinatio...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.

Cataract surgery is performed to remove the lens of the eye and replace it with an artificial one. The surgery is undertaken to cure cataract, which makes the lens of the eyes cloudy, making it difficult to see. The surgery is not considered to be a major one and is performed on an outpatient basis, meaning that the patient can go home the very same day without having to spend the night at the hospital. The procedure is very normal and is undertaken when cataract starts to affect the day-to-day ...more

There are many kinds of conditions that affect the eyes and make vision difficult - temporarily or even permanently. Uveitis is one such condition that causes eye inflammation in the middle layer of the tissue that resides in the wall of the eye - also known as the Uvea. The progression of the condition is sudden and the symptoms, quite painful.

Astigmatism is an eye condition where there is an imperfection in the cornea's curvature. The cornea and lens are smooth and equally curved in all directions, which helps to focus the light rays to the retina. But if there is an imperfection in the curvature, then you will suffer from a refractive error. Astigmatism is not an eye disease. It is simply a condition where the eye is not able to focus the light.

CAUSES:

Irregular shape of the cornea is the main cause for astigmati...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

LASIK or laser in situ keratomileusis, is a form of corrective surgery that help patients who are suffering from nearsightedness (Myopia), farsightedness (Hypermetropia) and even astigmatism (cylindrical power in glasses). This procedure aims at correcting the shape of the cornea, which is the transparent layer that lines the front of the eye. Through this procedure, the cornea is reshaped so that the retina receives a focused light.

So what are the health tips for people going through ...more

The cornea is the front layer of eyes that helps in focusing light to see objects clearly. In a cornea transplant surgery, the damaged cornea tissue is replaced by a healthy donor tissue. In medical terms, it is known as keratoplasty for corneal graft. The cornea needs to be clear, smooth, and healthy for a good vision. An unhealthy cornea leads to blurry vision.

Before transplanting cornea, doctors also try to treat the problem with other methods. However, if the condition is not gett...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
Glaucoma suspect
