Purpose: To describe the clinical and multimodal imaging features in a case of resolution of pre-macular fibrosis after photodynamic therapy (PDT) of retinal hemangioblastoma (RH) not related to von-Hippel-Lindau (VHL). Observations: A 25-year-old man presenting with blurred vision and central metamorphopsia in his left eye (LE) due to macular epiretinal membrane secondary to a peripheral RH. The patient had a comprehensive ophthalmic examination, including best corrected visual acuity (BCVA), wide-field fundus photography and autofluorescence (FAF), wide-field optical coherence tomography (OCT) and OCT angiography (OCTA), fluorescein angiography (FA) and indocyanine green angiography (ICGA) and ocular ultrasound. Baseline BCVA was 20/200 in his LE, and it improved to 20/40 nineteen months after anti-VEGF and photodynamic therapy were performed. The treatment led to a progressive shrinkage of the tumor and associated intraretinal exudation, and to a progressive resolution of the epiretinal membrane. Conclusions and importance: Treatments performed on the peripheral retina may result in changes at the level of the vitreo-retinal interface in the macular region. In our patient, after an intravitreal anti-VEGF associated with PDT, a posterior vitreous detachment (PVD) was induced resulting in auto-peeling of the macular epiretinal membrane secondary to a peripheral RH. An accurate assessment of the macular area by OCT is highly recommended in the first days following treatments.
