RESUMEN
PURPOSE: The authors describe a case of a Retinal capillary hemangioblastoma (RCH) in a pediatric patient with von Hippel-Lindau (VHL) syndrome that was successfully treated with systemic belzutifan. METHODS: Case report - The Clinical course was documented with serial fundus exams and multimodal imaging, including Optos wide field fundus photography and optical coherence tomography. A literature review was conducted to look for similar cases and/or discussion. RESULTS: A left RCH was noted on a standard VHL surveillance retinal exam of a then 15-year-old male with VHL syndrome. Over the course of 17 months this RCH was treated with focal laser therapy, photodynamic therapy (PDT), cryotherapy, bevacizumab injection, and endo laser ablation. Complications of these treatments included sub retinal fluid (SRF) and vitreomacular traction (VMT) necessitating laser retinopexy, scleral buckle, and pars plana vitrectomy with membrane stripping. After a 6-month interval from the last local therapy (endo laser treatment), there was minimal regression of the lesion and many concerning features persisted. At 22 months from presentation, the patient started belzutifan 120 mg PO daily with subsequent regression in size and less perfusion to the hemangioblastoma within 4 months. The patient is tolerating the systemic belzutifan with only the expected normocytic anemia and has not required transfusion therapy after 12 months of treatment. CONCLUSION: VHL disease is a rare and serious condition associated with multiple types of benign and malignant tumors. Belzutifan is tolerated in the adolescent population and can provide a systemic treatment alternative for VHL associated RCH.
RESUMEN
PURPOSE: To present a case of idiopathic retinal vasculitis, aneurysms, and neuroretinitis syndrome that was successfully managed with serial intravitreal aflibercept injections. METHODS: Ophthalmic imaging and visual acuity were used to monitor disease state and track treatment methods to determine the most valuable combination of treatment medication and treatment interval. RESULTS: A 28-year-old woman with idiopathic retinal vasculitis, aneurysms, and neuroretinitis syndrome status after panretinal photocoagulation of both eyes presented with bilateral cystoid macular edema. We demonstrate successful management of retinal cystoid macular edema associated with idiopathic retinal vasculitis, aneurysms, and neuroretinitis syndrome using serial intravitreal aflibercept injections. CONCLUSION: Intravitreal aflibercept has a useful role in managing the potential retinal complications associated with idiopathic retinal vasculitis, aneurysms, and neuroretinitis syndrome and provides further insights into treatment of the later stages of this rare disease.
