A Descriptive Study on Visual Outcome and Intraocular Pressure Control after Trabeculectomy with Manual Small Incision Cataract Surgery in Patients with Glaucoma and Cataract

Abstract

Context: Glaucoma is a optic neuropathy having multifactorial causes. Both cataract and glaucoma condition can influence management of the one another. Aims: To know the visual outcome and intraocular pressure control after combined trabeculectomy in patients with glaucoma and cataract. Settings and Design: It was a descriptive interventional study done for two years. All patients diagnosed to have significant cataract and diagnosed glaucoma were included in study. Methods and Material: After taking consent, combined surgery was performed and post-op follow up was done on 1st postoperative day and then on 1st week, 2weeks, 4weeks, 6weeks, 8weeks and 6 months. All parameters assessed and tabulated for statistical analysis. Results: Mean age of subjects was 59 years. 46.7% were males. Most of the patients (73.4%) were diagnosed as POAG. 26.7% were having PACG. Pre-operatively, 7 patients had vision better than 6/36. 13 patients had 6/36 and 10 patients had less than 6/36. At 6 weeks postoperatively, 76.7% had vision 6/9 or better, 16.7% had between 6/12 to 6/18, 6.7% less than 6/18. Mean IOP, Preoperatively among POAG and PACG was 19.90 and 33.25mmHg. Among POAG, Postoperatively at 6weeks, 8week, and 6months, IOP was 13.81, 13.91 and 12.72mmHg respectively. Postoperatively at 6weeks, 8week, and 6months, IOP was 19.75, 18.00 and 17.25mmHg in case of PACG. Conclusions: The study has showed the postoperative visual outcome and control of intraocular pressure is better with combined trabeculectomy with cataract surgery but still patients should be individualised according to their presentation.
