title: Comparison of 360-Degree Circumferential Trabeculotomy and Conventional Trabeculotomy in Primary Pediatric Glaucoma Surgery: Part 1.
abstract: OBJECTIVE
  To quantify the outcomes of a single circumferential trabeculotomy versus a single conventional trabeculotomy after 2 years of follow-up in patients who underwent primary pediatric glaucoma surgery.
  
  
  METHODS
  This was a retrospective study of patients aged 1 day to 3 years who underwent primary pediatric glaucoma surgery. A total of 45 patients (79 eyes) were followed up for 2 years. There were two groups: the 360-degrees circumferential trabeculotomy with illuminated catheter group and the conventional trabeculotomy group.
  
  
  RESULTS
  Mean age was 5.37 ± 6.32 months. There were 41 eyes with circumferential trabeculotomy and 38 eyes with conventional trabeculotomy. In the circumferential group, the technique could not be completed in 3 eyes (7.31%) because of severe canal malformations. Mean intraocular pressure and corneal diameter decreased in both groups postoperatively. At 2 years' follow-up, intraocular pressure (IOP) decreased, with 13.61 mm Hg in the circumferential group and 9.09 mm Hg in the conventional group. At 6 months postoperatively, corneal diameter decreased, with 0.52 mm in the circumferential group and 0.27 mm in the conventional group. Axial length remained the same.
  
  
  CONCLUSIONS
  Both procedures were successful, but circumferential trabeculotomy was better than the conventional procedure for lowering IOP, with an average of 4.52 mm Hg at 2 years' follow-up. The decrease in postoperative corneal diameter was also better in the circumferential group. The mean preoperative and postoperative axial lengths were similar in both groups; thus, the surgery did not influence this measurement in the studied cases.
