Eye Diseases


Eye Diseases
Some eye problems are minor and fleeting. But some lead to a permanent loss of vision. Common eye problems include
Cataracts - clouded lenses
Glaucoma - damage to the optic nerve from too much pressure in the eye
Retinal disorders - problems with the nerve layer at the back of the eye
Conjunctivitis - an infection also known as pinkeye

Your best defense is to have regular checkups, because eye diseases do not always have symptoms. Early detection and treatment could prevent vision loss. See an eye care professional right away if you have a sudden change in vision or everything looks dim or if you see flashes of light. Other symptoms that need quick attention are pain, double vision, fluid coming from the eye and inflammation.


At the age of 6, one child out of three has ametropia. This word refers to well-known disorders such as long-sightedness, astigmatism and short-sightedness. They can affect one eye or both of them. These disorders are easily corrected ! Besides, some can disappear as we get older, such as long-sightedness.



Long-sightedness :
The eye is too short : the image which is received gets impressed behind the retina and not on it. The eye needs to compensate by permanent accommodation which tires it.


Short-sightedness :
The eye is too long : the image which is received gets impressed in front of the retina and not on it. The distance between the retina and the cornea is too big and the eyes cannot focus on distant objects.
Astigmatism : The curvature of the cornea is very irregular. Instead of being round, it is oval, like a rugby ball ! In some rarer cases astigmatism is due to a fault in the crystalline lens. In both cases the objects appear distorted.

Maintaining Good Eyesight

Good eyesight plays an important role in your mobility and the enjoyment of life, so it's important to follow these basic steps to keep your eyes seeing clearly.

Visit Your Eye Doctor
You should visit your eye doctor for an eye exam at least once every one to two years to help maintain good eyesight. See your ophthalmologist if you experience eye infections or symptoms of disease like loss of or blurred vision, light flashes, eye pain, redness, itching, swelling and irritation around the eye or eyelid.

Practice Disease Prevention
Disease of the eye is the number one cause of blindness. Most diseases that cause blindness, like glaucoma and diabetes, can be treated or their progression slowed down with the proper diagnosis and management. While there is no cure for some eye conditions, there have been major medical advances for age-related macular degeneration, glaucoma, and cataracts. By visiting your eye doctor on a regular basis, you can catch any eye problems in their early stage when they are easier to treat.

Protect Your Eyes From the Sun's Harmful Rays
Constant exposure to ultraviolet light can damage your eyes. Too much exposure increases pigmentation in the eye, causing a discoloration known as "brown" or "sunshine" cataracts. Some eye diseases, such as macular degeneration, have been linked to UV exposure.

Wear Protective Gear and Eyewear During Work and Sporting Events
Wearing safety glasses and protective goggles while playing sports or working with hazardous and air-born materials lowers your risk for eye injury, impaired vision and complete loss of sight.
