Primary congenital glaucoma clinical presentation and evaluation of modified trabeculectomy

Primary congenital glaucoma is a relatively rare condition. A study on this subject to observe the mode of clinical presentation in our country and to evaluate the role of modified technique of trabeculectomy was undertaken. 30 eyes of 17 patients having primary congenital glaucoma were studies. The examination under general anaesthesia included (a) Anterior segment examination under operating microscope, (b) Corneal diameter measurement, (c) Fundus examination (d) IOP measurement and (e) Gonioscopy. The patients were subject to modified trabeculectomy operation. The assessment of the surgery was done during post-operative examination carefully. This paper includes an analysis of various clinical features of this condition. The observations revealed that the presenting symptoms are slightly different in our country compared to those in the developed countries. The overall success rate with our modified technique of trabeculectomy was 72.4 percent. Since most of our patients present with corneal opacity, we feel that modified trabeculectomy is a very effective surgical method for such cases.
