Cataract Diagnosis A diagnosis of cataracts is made by a full eye examination – this will also check for other problems such as glaucoma or retinal disease. Patient’s with cataracts should be able to point the the position of a light and their pupils should react normally. In advanced cataracts, the lens may appear a milky white or light brown. Cataracts can be definitively diagnosed with an ophthalmoscope. In a normal eye, when light, from the ophthalmoscope, is shone into it from a distance of about 2 feet the pupil lights up with a red reflex. In eyes with cataracts this red reflex is absent or diminished with the pupil retaining its dark appearance. All infants should be examined at birth and at six to eight weeks for cataract and eye conditions. Congenital cataracts must be treated within the first 3 months of life, if delayed vision may not develop normally. Prognosis Cataracts tend to grown in size over time and eventually may cause blindness. By blocking the view to the inside of the eye to medical examination, they may also prevent the diagnosis of other treatable eye

Occasionally after a lens is replaced the capsule sometimes thickens causing a progressive deterioration in vision however this condition may be treatable with laser correction. Prevention Although cataracts have no scientifically proven prevention, it is sometimes said that wearing ultraviolet-protecting sunglasses may slow the development of cataracts. Regular intake of antioxidants (such as vitamin A, C and E) is theoretically helpful, but taking them as a supplement has been shown to have no benefit. The less well known antioxidant N-acetylcarnosine has been shown in randomized controlled clinical trials to treat cataracts, and can be expected to prevent their formation by similar mechanisms. N-acetylcarnosine is a proposed treatment for other ocular disorders that are instigated, or exacerbated by oxidative stress including glaucoma, retinal degeneration, corneal disorders, and ocular inflammation....
