title: Inverse levels of pigment epithelium-derived factor and vascular endothelial growth factor in the vitreous of eyes with rhegmatogenous retinal detachment and proliferative vitreoretinopathy.
abstract: OBJECTIVE
  To determine the vitreous levels of pigment epithelium-derived factor and vascular endothelial growth factor in eyes with rhegmatogenous retinal detachment and proliferative vitreoretinopathy.
  
  
  METHODS
  Prospective, noncomparative case series.
  
  
  METHODS
  Pigment epithelium-derived factor and vascular endothelial growth factor concentrations were measured by enzyme-linked immunosorbent assay in 26 eyes with retinal detachment, 6 with proliferative vitreoretinopathy, and 14 with an idiopathic macular hole.
  
  
  RESULTS
  Pigment epithelium-derived factor concentration in proliferative vitreoretinopathy (0.57 +/- 0.05 microg/ml) was lower (P =.0069), and retinal detachment (2.37 +/- 0.34 microg/ml) was higher (P =.16) than that in macular hole (1.71 +/- 0.22 microg/ml). Vascular endothelial growth factor concentration (168 +/- 139 microg/ml) in proliferative vitreoretinopathy was significantly higher than that in retinal detachment (11 +/- 11 microg/ml, P =.0084) and macular hole (not detectable, P =.0095).
  
  
  CONCLUSIONS
  Lower levels of pigment epithelium-derived factor and higher levels of vascular endothelial growth factor may be related to ocular cell proliferation.
