title: Ultrasound biomicroscopic patterns after glaucoma surgery in congenital glaucoma.
abstract: OBJECTIVE
  This study aimed to demonstrate specific morphologic patterns in congenital glaucoma after various surgical procedures by means of ultrasound biomicroscopy (UBM) and to investigate correlations between UBM morphology and the effectiveness of glaucoma surgery in reducing intraocular pressure.
  
  
  METHODS
  Observational case series.
  
  
  METHODS
  Thirty four eyes of 18 consecutive patients, not older than 18 years, with congenital glaucoma and with a history of previous antiglaucomatous surgery underwent UBM examination of the anterior chamber angle in the treatment area and in an untreated region.
  
  
  METHODS
  The morphology of the anterior chamber angle region and the tissue reflectivity were analyzed.
  
  
  RESULTS
  Specific UBM patterns of the anterior chamber angle in congenital glaucoma were observed after goniotomy, trabeculotomy, trabeculectomy, deep sclerectomy, and cyclodialysis. In the first months after surgery, a limited correlation was found between morphology and the success of filtering surgery. Adhesions of the iris or the ciliary processes to the trabeculectomy cleft were detected in 19 of 25 eyes after filtering procedures.
  
  
  CONCLUSIONS
  In cases of cloudy cornea and unknown previous glaucoma surgery, UBM can be used to identify the type and localization of previous surgery in congenital glaucoma, thus assisting surgical planning for subsequent glaucoma management. The correlation between UBM morphology and the effectiveness of filtering surgery is less convincing than previously demonstrated in adults, possibly underlining the importance of individual nonsurgical factors for prognosis in congenital glaucoma.
