Cataracts are a very common condition that most people experience at some point in their lives. Cataracts slowly make the natural lens that sits behind the iris (the colored part of the eye) become yellow and hard. It slowly and progressively causes vision loss or blurring. Age-related cataracts are thought to be caused by the ultraviolet radiation from the sun. The sun's rays cause opacification of the fibers within the natural lens. There are several different types of cataracts besides the typical aging cataract. Presenile cataracts can be caused by diabetes, muscle dystrophy or skin problems.
Traumatic cataracts happen when the eye or head is exposed to blunt force or a penetrating force. Traumatic cataracts are known to form after ocular surgeries or car accidents and concussions. Toxic cataracts can form when the patient is taking certain medications like steroids, miotics, and antipsychotics. There are also secondary cataracts which can form after a patient has had some of the following conditions for a long time: anterior uveitis (inflammation of the colored part of the eye), a tumor in the colored part of the eye, acute angle closure glaucoma (loss of vision because of too much pressure inside of the eye ball) and several other conditions.
Posterior sub capsular cataracts are the most devastating to vision and forms along the back of the capsular bag the natural lens sits inside of. Cortical cataracts are spoke like projections that form in the front and back parts of the lens and can produce glare. 100% UV protection is always recommended to help slow down the progression of age related cataracts. Cataract surgery is also a possibility when it is the right time. Cataracts can be detected on your yearly routine examination and a proper treatment plan can be determined at that point.
