Purpose: Whereas its efficacy in preventing the progression of age-related macular degeneration (AMD) is yet established, the effect of photodynamic therapy (PDT) on quality of life and self reported patient satisfaction after the treatment is still under discussion. Therefore quality of life assessment after PDT seems appropriate.
Method: All patients, which underwent PDT in 2001 at the University Eye Hospital of Mainz, were interviewed using an AMD-specific modification of a standardised 32 items questionnaire on quality of life and patient satisfaction in ophthalmological patients. Information on the questionnaire's main aspects "private flexibility", "mobility", "flexibility in reading", "psychological stress" and "communicational flexibility" were derived as scores, which range from 1.0 (optimum self estimated quality of life) to 4.0 (worst). These scores were then related to clinical outcome parameters such as change in visual acuity during the PDT treatment period. Logistic regression models were used to assess significant associations (Likelihood Ratio test) between quality of life scores and clinical outcome parameters.
Results: 84 patients (50% female, median age 77 years) were interviewed, they underwent a median number of 3 PDT interve
