    Abstract:
    BACKGROUND: The treatment of patients with subfoveal choroidal neovascular membrane in age-related macular degeneration is unsatisfactory because only a limited number of patients are eligible. The aim of this study was to prospectively evaluate a new perifoveal treatment technique in patients with subfoveal choroidal neovascular membrane. METHODS: Between April 1992 and January 1994, 385 patients underwent clinical examination and fluorescein angiography. Eligibility criteria were met by 21 (5.5%) patients (22 eyes): well or poorly defined subfoveal choroidal neovascular membrane (< or = 3.5 disc diameters), without fibrosis, with visual acuity < or = 0.25. Visual acuity, morphological findings and complications were studied. The follow-up period was 12-32 months. RESULTS: The visual acuity before laser treatment ranged from counting fingers up to 0.25 (median 0.06). At the end of the follow-up (median 18 months) 28% (6/21) of patients showed a better visual acuity, whereas 44% (9/21) were unchanged and 28% (6/21) had deteriorated compared to visual acuity before treatment. In 71% (15/21) of eyes, resolution of the choroidal neovascular membrane was achieved with development of an atrophic laser scar. CONCLUSION: The visual outcome and the morphological findings after perifoveal laser treatment of subfoveal choroidal neovascular membrane in age-related macular degeneration show it to be an alternative method of treatment with favourable results. Due to inclusion criteria it is suitable only for a limited number of patients.
