This issue includes reviews of drugs for glaucoma, age-related macular degeneration (AMD), bacterial conjunctivitis, and dry eye disease. Allergic conjunctivitis is reviewed in a separate issue.

The results of the Age-Related Eye Disease Study 2 (AREDS2) have now been published. The primary purpose of the study was to evaluate the efficacy and safety of the carotenoids lutein and zeaxanthin and the omega-3 polyunsaturated fatty acids (PUFAs) docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) in reducing the risk of developing advanced age-related macular degeneration (AMD). A secondary goal was to test the effects of reducing the amount of zinc and eliminating beta carotene from the original AREDS formulation. Beta carotene has been shown to increase the risk of lung cancer in smokers and former smokers.

Drugs for glaucoma, age-related macular degeneration, bacterial conjunctivitis, and dry eyes are reviewed here. Ophthalmic drugs can have local and systemic adverse effects. In addition, for some elderly patients, the complexity of self-administering numerous ophthalmic drugs may be the limiting factor in their ability to care for themselves. Drugs for the treatment of allergic conjunctivitis will be reviewed in a future issue of Treatment Guidelines on Drugs for Allergic Disorders.

Cataracts are the leading cause of blindness worldwide because cataract surgery is not available to most people in developing countries.
