title: Adenoma arising from nonpigmented ciliary epithelium concomitant with neovascularization of the optic disk and cystoid macular edema.
abstract: OBJECTIVE
  To report a case of adenoma of the nonpigmented ciliary epithelium concomitant with marked neovascularization of the optic disk and cystoid macular edema (CME).
  
  
  METHODS
  Observational case report.
  
  
  METHODS
  A 34-year-old woman presented with a nonpigmented, vascularized tumor behind the iris and neovascularization of the optic disk (NVD). Visual acuity decreased gradually as a result of the development of CME.
  
  
  RESULTS
  Iridocyclectomy to excise the tumor was performed 8 months after initial examination. Histopathologic study revealed an adenoma arising from the NPCE. The levels of vascular endothelial growth factor were significantly elevated in both aqueous and vitreous humor obtained at surgery. The NVD and CME regressed after surgery, and the postoperative visual acuity improved to 20/40.
  
  
  CONCLUSIONS
  NVD and CME may develop secondary to adenoma of the nonpigmented ciliary epithelium. Increased levels of vascular endothelial growth factor in intraocular fluids may play a role in NVD and CME development.
