Surgical results of combined trabeculotomy-trabeculectomy for congenital glaucoma

Combined trabeculotomy-trabeculectomy was used in 40 eyes of 32 patients with primary congenital glaucoma [20 patients were females and 12 were males, their ages ranged between 7 months and 3 years with a mean of 1.42 years]. Primary combined trabeculotomy-trabeculectomy was the chosen intervention. No previous surgical intervention was done to any patient. All patients underwent thorough history taking and ophthalmic examination. The average follow up period was 8.9 months [6-12 months]. The main outcome measures were postoperative intraocular pressure [IOP], corneal clarity and diameter, bleb characteristics, time of surgical failure and complications. The success criteria included intraocular pressure inferior to 16 mm Hg under general anesthesia. The mean preoperative IOP was improved from 28.9 mm Hg to 14.1 mm Hg at 12 months postoperatively. A progressive improvement of the outcome parameters was observed in 37 out of 40 eyes. None of the patients had any sight-threatening intra or postoperative complications
