Cataract is clouding of the eyes
Cataracts occur when there is a buildup of protein in the lens that makes it cloudy. This precludes light from passing clearly through the lens. This causes loss of vision. Since new lens cells form on the outside of the lens, all the older cells are covenanted into the center of the lens resulting in the cataract.
The cloudy lens blocks the passage of light through the eye.
Types:
Age related: This type develops as a result of aging.
Secondary: This type develops due to medical conditions such as exposure to toxic substances, diabetes, ultraviolet radiation, certain drugs or radiation.
Congenital: This type is developed in babies who are sometimes born with it as a result of injury, infection, or poor development before they were born. This may also develop during childhood.
Traumatic: This form due to injury to the eye.
Symptoms:
They usually form slowly and cause few presages. The symptoms embrace:
• Vision becomes cloudy, foggy, blurry or filmy.
• Problems driving at night
• Trouble with glare during the day
• Sudden changes in glass prescription
• Double vision
• Advanced nearsightedness in the older people
Diagnosis:
Doctor dilates your eye pupil in order to examine the condition of the lens and other parts of the eyes. An eye exam will also be conducted to test how well you can see. If you already have glasses remember to bring it when you come for the appointment.
Treatment:
• If the vision can be corrected at the acceptable level with a change in prescription then eyeglasses including bifocal or contacts may be recommended. This will eliminate the need for surgery at that time.
• If cataracts intervene with your daily life and the vision cannot be corrected with the new glasses then you may have to undergo a surgery. The surgery involves removing the clouded lens and replacing it with a clear and artificial one.
• The surgery is very successful in restoring vision.
Prevention:
• As the cause of this not known hence there is no proven method to prevent it. It is important to have the eyes examined on a regular basis as cataracts are common in older adults.
• It is important to have regular eye checkup if you have risk factors or a family history of eye problems.
• People with a history of eye issues or other medical conditions increase the risk of eye disease.
• Disease such as diabetes may also need eye exams more frequently.
