title: [Optical Coherence Tomography Angiography in Diagnosis and Post-Treatment Assessment of Hemangioblastomas in Hippel-Lindau Disease].
abstract: BackgroundOptical coherence tomography angiography (OCTA) offers the possibility to visualize, non-invasively, blood vessels of the retina. In vascular tumors, especially hemangioblastomas in Hippel-Lindau disease, new information can be obtained with OCTA concerning structure of the tumor, tumor activity and treatment success.PatientsTen eyes of 10 patients with retinal hemangioblastoma in Hippel-Lindau disease were included. The age of the patients ranged from 19 years to 65 years (median 44 years).ResultsA total of 10 active and one inactive hemangioblastomas were examined with OCTA. In larger tumors, only the superficial blood flow could be visualized. Four hemangioblastomas were not treated due to their location near the optic nerve head. Six hemangioblastomas in the peripheral retina were treated with laser photocoagulation. In 4 eyes, a reduced blood flow could be shown directly after the treatment. The visualization of the perfusion was partially blocked after laser treatment.ConclusionOCTA enables innovative methods of pre- and postoperative assessment of retinal hemangioblastomas. It has the potential to give new information about the morphology, activity and effects of treatment. Prospective studies with longer follow-up are needed to evaluate the therapeutic relevance of this new imaging method.
