Abstract

PURPOSE - MATERIAL AND METHODS - RESULTS - CONCLUSION; Primary optic disc tumors are often a challenge for ophthalmologists. They have very different appearances, and many primary optic disc tumors are associated with syndromic diseases (especially phakomatoses). Because of the rarity of primary optic disc tumors, classification and assessment are often difficult.; A systematic search in the electronic patient files (period 01.01.2015 - 01.06.2022) of the Department of Ophthalmology of the University of Münster Medical Center for patients with primary optic disc tumors was performed. For each tumor entity, exemplary cases were selected, which are presented here in detail. The criteria for the exemplary case selection were a clear diagnosis, the presence of suitable image material and follow-up examinations in our clinic.; The search yielded seven cases with three different primary tumor entities in the optic disc region (capillary hemangioblastoma, astrocytic hamartoma and melanocytoma). Four patients were selected as examples and are presented here: two cases for capillary hemangioblastoma (one isolated and the other in the context of Von-Hippel-Lindau syndrome) and one case each for astrocytic hamartoma and melanocytoma). We outline the further diagnosis and the course of the disease and we give an overview of the essential features of the underlying tumors in each case.; The knowledge of the different primary tumors of the optic disc is necessary for a correct diagnosis and for the differentiation from malignant processes and optic disc anomalies. In many cases, further interdisciplinary diagnostics are necessary. Multimodal imaging is helpful and a referral to a center for ocular tumors is worth considering.
