title: Choroidal neovascularization in primary hyperoxaluria.
abstract: OBJECTIVE
  To report a case of primary hyperoxaluria in which choroidal neovascularization developed bilaterally.
  
  
  METHODS
  Observational case report.
  
  
  METHODS
  A 22-year-old man with a history of type I primary hyperoxaluria complained of a slow but progressive loss of vision in both eyes for the preceding 8 months. The clinical, fluorescein, and ocular coherence tomography findings are reported.
  
  
  RESULTS
  Fluorescein angiography confirmed the presence of choroidal neovascularization in both eyes at the edge of previous macular scars. Ocular coherence tomography scans were obtained to better characterize the clinical pathology.
  
  
  CONCLUSIONS
  In a patient with type 1 primary hyperoxaluria, the presence of choroidal neovascularization in both eyes outside but adjacent to an area of previous macular scarring is reported. These findings are in harmony with the assumption that mechanical factors from the oxalate deposition promote choroidal neovascularization.
