Age-related macular degeneration: update for primary care

Age-related macular degeneration is the leading cause of severe vision loss among the elderly. In this condition, central vision is lost, but peripheral vision almost always remains intact. Affected persons rarely require canes or guide dogs. The diagnosis of age-related macular degeneration is based on symptoms and ophthalmoscopic findings, and the disease can be classified into atrophic and exudative forms. The two currently proven treatments are laser photocoagulation and photodynamic therapy, but these measures are effective in only a small fraction of eyes with the exudative form of macular degeneration. Vision rehabilitation can help patients maximize their remaining vision and adapt so that they can perform activities of daily living. Families need encouragement in providing support and helping patients adjust to being partially sighted.
