Does acetylsalicylic acid have a negative influence on photodynamic therapy?
Lw U; Kohlhof JK; Ruprecht KW Augenklinik, Universität Homburg (Saar), Kirrberger Strasse 1, 66424 Homburg. aurupr@med-rz.uni-saarland.de BACKGROUND: Non-thermal photodynamic therapy (PDT) is presently being used for the treatment of certain forms of age-related macular degeneration (AMD). This therapy results in selective occlusion of newly growing vessels. Due to this effectiveness of PDT the question came up whether inhibitors of platelet aggregation have an influence on PDT. PATIENTS AND METHODS: Our retrospective study included 60 patients with mainly classic subfoveal choroidal neovascularizations (CNV) due to AMD. All patients were treated by PDT. Thirty patients took acetylsalicylic acid (aspirin) because of their general disease before and during treatment. In the control group none of the patients took acetylsalicylic acid. RESULTS: Best corrected visual acuity and measured dimension of the choroidal neovascularization showed before beginning PDT no statistically significant
