Patient knowledge concerning age-related macular degeneration: an AMD questionnaire.

BACKGROUND: Age-related macular degeneration (AMD) is a disease with rising prevalence. This study evaluates patients' knowledge and the need for more patient information. METHODS: 271 patients with AMD were asked to complete a questionnaire concerning their knowledge about AMD. 150 patients were interviewed by a physician and 121 patients completed the questionnaire on their own. RESULTS: 79.4 % of patients had previous knowledge about AMD. Most patients, 97.3 %, got their information from physicians. 58 % of patients find their knowledge concerning AMD adequate. Only 23.9 % knew about aid organizations for patients with visual impairments. DISCUSSION: Though the majority of patients had good knowledge concerning AMD, there was a large percentage of patients who seemed to lack information. Physicians should actively ask their patients if they have any questions related to their disease. Medial focus on AMD and information about aid organizations could help patients to cope with their disease. CONCLUSION: A large number of patients seemed to need additional information. We suggest that ophthalmologists provide general information concerning AMD to their patients every 3 to 5 years. Information about aid organizations specializing in visual impairment could also be provided. Well-informed patients would be better able to follow their physician's instructions and would have a better understanding of their disease, particularly for the sake of therapy.

Level of knowledge about glaucoma in Vienna.

BACKGROUND: Glaucoma is a chronic and serious disease calling for consistent lifelong therapy. The patient's compliance requires that he/she be well informed about the disease. The purpose of the present study was to determine the level of knowledge about glaucoma, and compare young patients with older ones as well as glaucoma patients with nonglaucoma ones. METHODS: A total of 1110 questionnaires were distributed to patients and their relatives at the outpatient eye clinic of Hietzing Hospital (Vienna), of which 1041 were returned. The questionnaire comprised 18 questions. Patients were divided into two groups: group 1 consisted of those aged 18-60 years, while group 2 consisted of those older than 61 years. RESULTS: In total, 941 questionnaires were evaluated; 72.8% of the respondents were older than 60 years, and one-half of the respondents had glaucoma (51%). The majority of patients had "moderate knowledge" of the disease (41.87%), followed by "poor knowledge" (32.52%). Glaucoma patients had considerably better knowledge of the disease (p < 0.01) than did nonglaucoma patients. Younger patients were significantly better informed than older ones (p < 0.01). Nonglaucoma patients with a positive diagnosis of glaucoma among their circle of friends or family were significantly better informed (p < 0.01) than those without such persons in their circle of friends. CONCLUSION: Persons with glaucoma are much better informed about the disease than nonglaucoma patients, but the general level of knowledge is very low. Notably, younger patients were better informed than older ones. The present study, comprising a large number of patients, revealed poor knowledge of glaucoma among patients with the disease and especially among nonglaucoma patients in Vienna.
