title: [OCT and neovascular glaucoma].
abstract: BACKGROUND
  Neovascular glaucoma is a chronic and sight-threatening disease. Four different grades have been described. Anterior chamber optical coherence tomography (OCT) is a new imaging technique allowing the visualization of the anterior segment. The purpose of our study was to describe the appearance of the different neovascular glaucoma grades with the OCT in order to refine the clinical analysis of this disease.
  
  
  METHODS
  Eleven patients (nine men and two women) with different grades of neovascular glaucoma were analyzed in this study. Neovascular glaucoma complicated central retinal vein occlusion in seven patients and diabetic retinopathy in four patients. All patients had bilateral biomicroscopical examination and OCT analysis. OCT images and clinical examination were then compared.
  
  
  RESULTS
  No modifications could be observed using OCT in patients with grade 1 neovascular glaucoma. For grade 2, a slightly hyper-reflective linear iris secondary to neovascularization was observed. For grade 3, OCT images showed a thickened hyper-reflective iridocorneal angle with possible iridocorneal synechiae. For grade 4, the iridocorneal angle was closed and associated with iris contraction and uveae ectropion.
  
  
  CONCLUSIONS
  OCT is a new promising technique for the precise analysis of different grades of neovascular glaucoma. It certainly helps in the management of such cases.
