title: Ultrasound biomicroscopy in the diagnosis of persistent hypotony after vitrectomy.
abstract: OBJECTIVE
  To describe a case of persistent hypotony after an otherwise successful vitreous surgery for epiretinal membrane, in which ciliochoroidal detachment was detected by ultrasound biomicroscopy but not by ophthalmoscopy.
  
  
  METHODS
  We used ultrasound biomicroscopy to determine the cause of persistent postoperative hypotony.
  
  
  RESULTS
  Ultrasound biomicroscopy clearly disclosed ciliochoroidal detachment. In an attempt to resolve ciliochoroidal detachment, we performed vitrectomy and fluid-gas exchange combined with diathermy around the sites of sclerotomy. Postoperatively, the regression of ciliochoroidal detachment was confirmed by ultrasound biomicroscopy.
  
  
  CONCLUSIONS
  Using ultrasound biomicroscopy, we were able to visualize ciliochoroidal detachment and its regression clearly, which we had not observed during ophthalmoscopy.
