Photocoagulation for diabetic retinopathy
Article Abstract:
A 30-year-old patient with diabetes complained of blurred vision, and was found to have diabetic retinopathy, a disorder caused by new growth of retinal blood vessels (neovascularization), a common complication of diabetes. The patient was at high risk for severe loss of vision, and was therefore treated with photocoagulation, which delivers tiny burns by laser or other techniques to the retina. After treatment the patient's vision returned to normal, and remained so at follow-up five months later. Two clinical trials have found that photocoagulation is effective in preventing loss of vision in patients at high risk for loss of sight from retinopathy. For patients with less severe retinopathy, the choice is less clear because of the risk of side effects. A study comparing early and deferred treatment did not find a difference between the two. Adverse effects of photocoagulation on vision were evident in the posttreatment period, but less extensive photocoagulation produces less damage. It is concluded that, as long as the patient can be monitored, patients with mild to moderate retinopathy should not be treated with photocoagulation, but treatment should not be delayed for patients at high risk. Limited treatment should be considered when the macula (a part of the cornea) is at risk. Regular examinations by an ophthalmologist to ensure early detection and treatment of diabetic retinopathy is the best method of preserving good eyesight.

Antioxidants and zinc to prevent progression of age-related macular degeneration. (ABSTRACTS AND COMMENTARY)
Article Abstract:
Antioxidant vitamins such as vitamin C and E combined with the mineral zinc can slow the progression of aged-related macular degeneration. However, the same combination of nutrients does not appear to slow the progression of cataract.
