[Disease perception in patients with wet age-related macular degeneration]. / Krankheitswahrnehmung bei Patienten mit einer feuchten altersabhängigen Makuladegeneration.

ABSTRACT

BACKGROUND: The disease perception of the patients treated with intravitreal injections of anti-vascular endothelial growth factor due to wet age-related macular degeneration was investigated. PATIENTS AND METHODS: 177 questionnaires focusing on the development of the perceived visual acuity and the quality of life were evaluated. The subgroup 1 included 125 patients (70.6%) with a unilateral wet age-related macular degeneration. The subgroup 2 included 52 patients (29.4%) with a bilateral wet age-related macular degeneration. RESULTS: Patients would almost always recommend the therapy to a friend (97.2%). The critical remarks are related to the uncertain course of the disease (22.8%) and the uncertain duration of the treatment (19%). There was a discrepancy between the measured visual outcome and the perceived one in 5.6% in the subgroup 1, and in 38.5% in the subgroup 2. This difference was statistically significant (chi-square test with p<0.01). CONCLUSIONS: The treatment of wet age-related macular degeneration with intravitreal injections of anti-vascular endothelial growth factor is judged positively. Binocular affected patients have a higher disease perception and therefore a poorer self-assessment of their visual acuity and their quality of life compared with monocular affected patients.
