Abstract:

Purpose: To evaluate outcomes of trabeculectomy in terms of IOP control and its safety in terms of peroperative and post-operative complications in Primary Congenital Glaucoma. Material and Methods: Thirty eyes of 17 patients were included in this case series after diagnosis of primary congenital glaucoma. Patients with secondary congenital glaucoma due to trauma, surgery, inflammation, Sturge Weber Syndrome, Neurofibromatosis, cataract, uveitis, aphakia and pseudophakia were excluded from the study. Informed consent was taken from parents. Examination under anesthesia was done before surgery to record preoperative IOP, corneal diameter and anterior and posterior segment abnormalities. Primary trabeculectomy was done. Post-operative IOP and corneal diameter was recorded at 1st, 3rd and 6th month and every 6 months thereafter under general anesthesia. IOP at 12th month of surgery was the final outcome which was considered significant if IOP was less than 21 mm Hg with stable corneal diameters. Results: Mean preoperative IOP was 25.8 mm Hg. Twenty-three (76.66%) eyes out of 30 eyes were considered successful with mean IOP of 15.3 mm Hg at last follow-up while 7 (23.33%) cases of failure were observed with postoperative mean IOP of 27.71 mm Hg. These patients underwent additional surgeries to control IOP. Hyphema was the only complication observed in this study. Postoperative cataract developed in 5 eyes. Conclusion: Primary trabeculectomy is an effective operation and safe surgery for primary congenital glaucoma.
