What are the main causes of cataracts?
Most cataracts are caused by normal changes in your eyes as you get older. When you’re young, the lens in your eye is clear. Around age 40, the proteins in the lens of your eye start to break down and clump together. This clump makes a cloudy area on your lens — or a cataract.
What causes congenital cataract?
Cataracts present from birth (congenital cataracts) are sometimes caused by a faulty gene being passed to a child from their parents. This fault means that the lens does not develop properly. It’s estimated there’s a family history of congenital cataracts in around 1 in every 5 cases of the condition.
How can you tell the difference between mature and immature cataracts?
Mature cataract: This is a cataract that is opaque, totally obscuring the red reflex. It is either white or brunescent. Immature cataract: This is a cataract characterized by a variable amount of opacification, present in certain areas of the lens.
What is age related cataract?
Cataracts are when the lens, a small transparent disc inside your eye, develops cloudy patches. Over time these patches usually become bigger causing blurry, misty vision and eventually blindness.
What are cataracts?
A cataract is the clouding of the normally clear lens that sits in the eye behind the pupil. Most cataracts are related to aging. More than half of all Americans have had a cataract or cataract surgery by age 80.
What is a trauma cataract?
Traumatic cataract is a clouding of the lens that may occur after either blunt or penetrating ocular trauma that disrupts the lens fibers. Most traumatic cataracts are intumescent, but their type and clinical course depend on trauma mechanism and the integrity of the capsular bag.
Which is the most common cataract in age old patient?
Cortical cataracts are most likely to affect older patients with diabetes. When a cortical cataract is present, the most common symptom is excessive glare. Like any other cataract, it’s important to catch a cortical cataract early!
What stage should cataracts be removed?
The operation can be performed at any stage of cataract development. There is no need to wait until your cataract is “ripe” before removing it. Most people choose to have their cataracts removed when the change in their vision starts to cause them difficulties in everyday life.
What is the latest treatment for cataracts?
Laser-Assisted Surgery is Revolutionizing Cataract Treatment
That probe emits ultrasonic energy to break up the damaged lens. A second probe is then used to suction out the tiny fragments, followed by a third probe used to insert and position the new artificial intraocular lens implant.
Should an 80 year old have cataract surgery?
By age 80, more than half of all Americans either have a cataract or have had cataract surgery. A cataract needs to be removed only when vision loss interferes with everyday activities, such as driving, reading, or watching TV. Sometimes a cataract should be removed even if it does not cause problems with your vision.
What is the difference between cortical and nuclear cataract?
Nuclear cataracts form in the middle of the lens and cause the nucleus, or the center, to become yellow or brown. Cortical cataracts are wedge-shaped and form around the edges of the nucleus.
