Isolated Retinal Capillary Hemangioblastoma: A Rare Case
Main Article Content
Abstract
Retinal Capillary Hemangioblastoma (RCH) generally has clinical onset in first two decades of life. It is associated with Von Hippel Lindau (VHL) disease because RCH is the most frequent and earliest manifestation of VHL disease. A 20 years-old-male presented with painless blurred vision in left eye since 2 weeks prior to the admision and no other complaint. He had no significant medical history, trauma and family history. His best corrected visual acuity was 20/20 in right eye and 20/400 in left eye with normal anterior segment. Fundus examination on left eye revealed a globular reddish lesion with dilated feeding vessel and turtous draining vein at the inferotemporal retina. The B-Scan Ultrasonography showed The B-Scan Ultrasonography showed dome shaped lesion. We performed abdominal ultrasonography and brain MRI to detect other lesion but showed the normal results. Argon laser photocoagulation has performed as a treatment. Retinal Capillary Hemangioblastoma is one type of Retinal Hemangioma. The pathogenesis may associated with Von Hippel Lindau Disease by “VHL tumor suppressor gene” which is located on chromosome 3p25–26. The radiological imaging has performed to detect systemic lesion and showed the normal results. After argon laser photocoagulation treatment, the visual aquity became 20/300 and fundus examination showed the scar in margin tumor with shrinkage feeding vessel. Based on ophthalmology and systemic examinations, we found a Retinal Capillary Hemangioblastoma as the hallmark manifestation in this case. Early diagnosis and argon laser treatment has benefit in controlling progression of disease. Systemic long term follow-up still needed to detect multisystem predisposing lesion.
