RESUMEN
Purpose: The authors report three separate cases of type 1 retinopathy of prematurity (ROP) treated with intravitreal bevacizumab before, or at 34 weeks postmenstrual age (PMA), with subsequent development of secondary glaucoma. Observations: All three cases involve patients born ≤24 weeks and meeting the American Academy of Pediatrics criteria for ROP screening. Prior to treatment, each patient was noted to have normal anterior chamber structures with no signs of glaucoma. Each patient developed type 1 ROP and was treated with intravitreal bevacizumab, which was administered at or before 34 weeks PMA. Following the administration of intravitreal anti-vascular endothelial growth factor (VEGF), each patient developed a suspected open-angle glaucoma (OAG) within an approximate 4-week time frame. In these cases, the presentation of glaucoma differed from those that have been previously reported in the literature. Conclusion and importance: Based on similar timing of glaucoma development following intravitreal bevacizumab injections, we hypothesize that the administration of anti-VEGF agents to very premature infants (≤24 weeks) at or before 34 weeks PMA, may predispose them to the development of secondary glaucoma through an unknown and possibly novel pathway.
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.
