astigmatism |
|
- The three most common reasons people need glasses are far sightedness, near sightedness and astigmatism. Many people think astigmatism is a disease or neurological problem. It is not. It is an abnormality in the optical part of the eye. It produces a blurred image. |

|
blepharitis |
|
- Blepharitis is an inflammation of the eyelid. It develops at the place where the mucous membrane on the underside of the lid joins the skin on the top of the lid. It occurs in both children and adults. The condition can be chronic and recur. |
|
|
ectropion |
|
- Ectropion is an outward turning, or eversion, of the eyelid margin. It may be mild or a total eversion, which exposes the mucous membrane lining underneath the lid. It usually involves the lower lid and not the upper. |
|
|
scleritis |
|
- The sclera is the white, outer coat of the eye. When this area becomes inflamed, the condition is called scleritis. |
|
|
corneal injury |
|
- The cornea (corn-ee-ah) is the clear window on the front of the eye that covers the coloured iris and pupil. Injury to the cornea causes hazy vision and scarring. It can also cause a loss of vision. |
|
|
corneal transplant |
|
- The cornea is the clear covering of the eyeball. With corneal transplantation, a part of a person's cornea is removed. It is then replaced with a portion of a cornea from a donor eye. In some cases, only the surface portion of the cornea needs to be removed. This is referred to as lamellar keratoplasty. In the majority of cases, however, the entire thickness of the cornea must be replaced. This is called penetrating keratoplasty. |
|
|
dry eye |
|
- Some people do not produce enough tears to keep the front surface of the eye lubricated and comfortable. This condition is known as dry eye. |

entropion |
|
- Entropion is a condition in which the eyelid margin turns in against the eyeball, or inverts. This inversion causes the eyelashes to rub against the surface of the eye. |
|
|
retinal detachment |
|
- The retina is the nerve layer that lines the inside of the back of the eye. It senses light and sends images on to the brain. When the retina is separated from the layer beneath the retina that gives it nourishment, called the choroids, this is called retinal detachment. The retina does not work when it is detached. This is a very serious problem and, if untreated, almost always leads to blindness. |
|
|
Sjogren syndrome |
