JUXTAPAPILLARY CAPILLARY RETINAL ANGIOMA AND EPIRETINAL MEMBRANE MANAGEMENT IN A MONOCULAR PATIENT WITH VON HIPPEL-LINDAU SYNDROME.

Purpose: To report a case of von Hippel-Lindau syndrome in a monocular patient with progressive vision loss due to a juxtapapillary capillary retinal angioma and an epiretinal membrane (ERM) formation.

Patient: We describe a 37-year-old white male patient with von Hippel-Lindau syndrome who presented for retinal evaluation. The right eye was blind with no light perception vision. The left eye had a best-corrected visual acuity of 20/30 and exhibited a peripheral capillary hemangioblastoma at 12 o'clock and a juxtapapillary capillary hemangioma with an ERM covering the fovea. The patient underwent two sessions of fluorescein-potentiated argon laser treatment to the peripheral capillary hemangioblastoma with initial stabilization of vision. After 18 months of follow-up, the ERM contracted causing decline in vision to 20/50. Intravitreal injection of bevacizumab was given without improvement in vision or distortion. Twenty-five-gauge pars plana vitrectomy with ERM peeling and internal limiting membrane removal was performed with immediate improvement in vision and distortion.

Conclusion: This case suggests that pars plana vitrectomy is a reasonable treatment option for vision loss due to a juxtapapillary capillary retinal angioma and ERM formation.
