RESUMO
BACKGROUND: Inherited retinal diseases (IRDs) refer to a heterogeneous group of rare disorders that potentially lead to blindness. Emerging therapeutic options have led to a growing interest in IRDs; however, there are insufficient systematic studies on IRDs in Germany characterizing the demographics and management in clinical practice. OBJECTIVE: To characterize the care for IRD patients in Germany, to assess the applied diagnostics, the use of databases and the implementation of education in ophthalmic genetics. METHODS: The anonymous online survey (SoSci Survey GmbH) was sent to all German ophthalmology departments listed on the website of the German Ophthalmological Society and to three practices focusing on IRDs. RESULTS: The overall response rate was 44.8%. Almost all institutions (93.6%) reported seeing IRD patients, but university and non-university hospitals differed in the number of patients. Databases are used in 60% of universities but only in 5.9% of non-university hospitals. Regarding the number of patients with genetic diagnostics, 53% of the non-university and 12% of the university sites reported that 20% at most of their patients had received a molecular genetic diagnosis. The results of the IRD practices are comparable with the university hospitals. Patients with biallelic RPE65 mutations-associated IRD, potential candidates for treatment with voretigene neparvovec (Luxturna®), were followed in 9/25 participating university departments. CONCLUSION: This survey highlights the deficits in the management of IRD patients. In particular, we found a clear difference between university and non-university hospitals in the rate of patients with known molecular genetic results. Improvements should be initiated in the latter, especially because of existing and emerging therapeutic options.
