[Histological findings in bilateral asymmetrical vasoproliferative retinal tumor].

We present a case of a bilateral vasoproliferative tumor of the retina in a young man. The first symptom was visual impairment due to vitreous hemorrhage. The right eye showed small tumors which were successfully treated by repeated cryocoagulation, photocoagulation and bevazicumab injection. The tumor in the left eye was larger and eventually led to a painful secondary glaucoma. After enucleation, this tumor was examined histologically and immunohistochemically. The clinical and histological differential diagnoses and therapeutic options are discussed.
