title: Presumed combined hamartoma of the retina and retinal pigment epithelium with preretinal neovascularization.
abstract: OBJECTIVE
  To describe a case of presumed combined hamartoma of the retina and retinal pigment epithelium associated with preretinal neovascularization.
  
  
  METHODS
  Observational case report.
  
  
  METHODS
  We report clinical and angiographic findings of a 26-year-old woman.
  
  
  RESULTS
  The patient presented with mild vitreous hemorrhage and slowly decreasing vision in the right eye. A combined hamartoma of the midperipheral retina and retinal pigment epithelium with an epiretinal membrane causing traction to the macula was found. Fluorescein angiography showed areas of capillary nonperfusion and a large preretinal neovascularization peripheral to the hamartoma.
  
  
  CONCLUSIONS
  A combined hamartoma may be associated with retinal capillary nonperfusion and preretinal neovascularization, suggesting that significant retinal ischemia can occur with a combined hamartoma.
