title: Juxtapapillary capillary hemangioblastoma.
abstract: BACKGROUND
  Juxtapapillary capillary hemangioblastomas are vascular lesions that occur on the optic nerve head or immediately adjacent to the optic disc. Although juxtapapillary capillary hemangioblastomas may appear as an isolated clinical finding, they are more likely to be a precursor to the diagnosis of von Hippel-Lindau (VHL) disease. When associated with VHL, the ocular complications from hemangioblastoma are generally greater, and subsequently the prognosis is poorer than for isolated entities.
  
  
  METHODS
  A 67-year-old white male presented to our clinic complaining of decreased vision in both eyes at distance and near. A dilated fundus examination revealed a swollen left optic nerve. Visual field testing revealed an inferior arcuate defect in the left eye. Laboratory and radiological testing were normal. Fluorescein angiography showed filling during the retinal arterial phase with late diffuse leakage. Based on these results, a diagnosis of juxtapapillary capillary hemangioblastoma was made. This was later confirmed when fundus photographs taken 7 years earlier were obtained, revealing a stable appearance to the nerve.
  
  
  CONCLUSIONS
  Potential ocular complications of juxtapapillary capillary hemangioblastomas include vision loss secondary to subretinal and intraretinal fluid, as well as epi-retinal membrane formation and, rarely, exudative retinal detachment. Management ranges from observation to surgical intervention, although definitive treatment guidelines have yet to be established. In addition, it is important for the eye care practitioner to be aware of the association with VHL disease, so that patients may be appropriately referred and managed for other possible systemic complications of the disease.
