Some rare and common eye disease that can be inherited.
There are many genetic eye disorders which are inherited that a person should watch out for. Some are commonly known and some are very rare. If you know of family members that have certain eye diseases or disorders, you should always be on the look out for them in yourself.
Listed below are some rare and some common eye disorders that every person should watch for. If you think you may have one of these disorders, contact your eye doctor as soon as possible.
Cataracts are a common eye disorder. Many people don’t know that cataracts can be inherited. A cataract is a clouding of the eye’s clear lens. A cataract prevents light rays from easily reaching the retina and causes blurred and hazy vision.
Cataracts usually develop as part of the aging process but may also come from injury, certain diseases, medications, or genetic inheritance.
Common symptoms of a cataract are cloudy or blurry vision, problems with light, faded colors, double vision, and frequent changes in contacts or glasses. Double vision will go away as the cataract grows.
Cataracts are detected by one of three tests. There is a visual acuity test which is an eye chart test to see how well you can see at various distances. A pupil dilation is when the pupil is widened with eyedrops. This allows the doctor to see more of the retina and look for other problems. The last test is a tonometry test which measures fluid pressure inside the eye. Increased pressure may be a sign of glaucoma.
If your vision is only slightly blurry, the cataract may require no treatment at all. You may need a change in your eyeglass prescription which may provide improvement for awhile. Once a cataract has formed, there are no medications, eye drops, exercises or glasses that will cause it to disappear. Once your vision becomes impossible to handle with a change in your eyeglass prescription, surgery should be considered. Under a microscope, a small incision is made into the eye. The cloudy lens is removed from the eye and a plastic intraocular lens is inserted. The incision is then closed. This usually takes care of the cataract.
Glaucoma is also a common eye disorder. Glaucoma is a group of diseases that can lead to damage to the eyes’ optic nerve and result in blindness. Glaucoma damages the optic nerve because of increased pressure inside of the eye.
In a congenital type of glaucoma, children are born with defects in the angle of the eye that slow the normal drainage of fluid.
There are usually obvious symptoms such as sensitivity to light, cloudy eyes, and excessive tearing. This is usually treated with surgery. Medications may have unknown effects in infants and be difficult to give them. Eye surgery is safe and there is an excellent chance of good vision.
In nearsigntedness or Myopia, the eyeball is egg-shaped rather than round. Light focuses in front of the retina instead of directly on it.
In rare cases, nearsightedness is caused by eye problems such as cataracts and keratoconus. People who are nearsighted have an increased risk of retinal detachment and of developing glaucoma.
Retinitis Pigmentosa (RP), is a rare eye disease. The light-sensitive retina of the eye slowly and progressively degenerates, eventually causing blindness. There is no known reason for RP. If neither parent has RP then at least one parent must be a carrier for a child to get this disease.
There is no treatment for RP. Some think that Vitamin A may slightly delay vision loss. Occupational therapy may help before much of the vision is lost.
Retinal Detachment is usually caused by Posterior Vitreous Detachment or PVD. PVD is when a thick fluid, or vitreous gel, fills the center of the eye then shrinks and separates from the retina.
There are many exams and tests that can be done to detect if you have a higher chance of a retinal detachment in the future. First learn about the symptoms, problems associated with, and risk factors of retinal detachment. Test near and distance vision and side vision. If RD is not detected, identify problems that could lead to or result from RD.
The direct causes of RD are tears or holes in the retina, traction on the retina, and fluid buildup under the retina.
If you think any of these things may have happened to you, go to the doctor immediately.
These are some common and uncommon eye disorders which can be inherited. If you have any questions about the eye disorders listed, please contact an eye doctor. You don’t want to take a chance of losing your sight.
