    Effectiveness of trabeculectomy on glaucoma patients in Ibadan
    (2001) Agbeja-Baiyeroju, A. M.; Omoruyi, M.; Owoaje, E. T.
    This study was designed to determine the effectiveness of trabeculectomy on African patients. All patients who underwent trabeculectomy over a 10-year period, January 1987 to December 1996 were included in the study. Information extracted from their case notes included age, sex, type of glaucoma, number of years of glaucoma before surgery, eye involved, and visual acuity pre-operatively and postoperatively. Intraocular pressures at presentation, preoperatively and post operatively (2 days, 1 week, 3 months, 6 months, 12 months and last clinic visit) were also recorded. Other data collected included pre-operative anti glaucoma therapy, additional techniques at surgery, complications of surgery, presence of a filtering bleb and follow-up period post operatively. A success rate of 91.2% was obtained from 433 eyes operated upon, The most significant outcome was the presence of a filtering bleb which had a better success rate than the absence of a bleb. High success rates were recorded in the age groups “>60 years and 20-40 years", the lowest success rate was in the “less than 20 years of age". All the patients with developmental glaucoma had a successful outcome (100%) while only 50% of the secondary glaucoma were successful. Patients with open angle glaucoma had 92% success rate. Complications of surgery were mostly transient. It was concluded that the presence of a bleb was a good indication of the control of intraocular pressure and that early surgery gave a more successful outcome than late surgery.

    Trabeculectomy in young Nigerian patients
    (2002) Agbeja-Baiyeroju, A. M.; Owoaje, E. T.; Omoruyi, M.
    The results of 89 trabeculectomies performed on 56 patients under the age of 30 years were reviewed. Data collected included age, sex, type or glaucoma, number of years of glaucoma before surgery, visual acuity, intraocular pressure, complications of surgery, presence of a filtering bleb and follow-up period. Complete success, denoted by a postoperative lOP of 21mmHg or less without medical therapy, occurred in 50 eyes (56.2%). Qualified success, in which lOP was 21mmHg or less with additional medical therapy occurred in 31 eyes (34.9%) and failure, in which lOP was greater than 21mmHg in spite of medical treatment occurred in 8 eyes (8.9%). Success was therefore achieved in 91.1 % attaining an lOP of 21mmHg or less, with or without additional medical therapy. The most statistically significant factor was age groups in which the highest success rate of I00% was achieved in the age group 20-29 years. The difference in the success rate across the age groups was statistically significant (x2 = 8.04, p = 0.0 I). Fornix based conjunctival flaps were also found to be associated with a statistically significant higher success rate (97.9%) as opposed to limbal based flaps (85.4%), X2= 4.81, p = 0.03. Males in the study group had a significantly higher success rate (97%) than females (78.3%), X2= 5.86, P = 0.011. A success rate of 100% was recorded in patients with developmental glaucoma, 86.1% in congenital glaucoma and 33.3% in secondary glaucoma. All the repeat trabeculectomies had congenital glaucoma. The presence of a bleb, although it had a higher success rate (93.4%) compared with the absence of a bleb (84.6%), was not statistically significant (x2 = 1.19, P = 0.27). Complications of surgery were mostly transient.
