Objective: To determine the frequency of raised intraocular pressure in pseudophakic undergoing Nd YAG laser posterior capsulotomy. To compare the frequency of raised intraocular pressure in pseudophakic undergoing high and low energy Nd YAG laser posterior capsulotomy Methods: This Descriptive case series included 140 patients with pseudophakic posterior capsular opacity. After dilating the pupils with tropicamide Nd YAG laser posterior capsulotomy was performed and the total amount of energy used was noted. The frequency of raised IOP in post-laser patients and comparison of frequencies of raised IOP undergoing high and low energy Nd YAG laser posterior capsulotomies (≤ 50 MJ labeled as low energy and > 50 MJ labeled as high energy) were calculated Results: The mean age was 57.37 ±8.74. Mean pre laser IOP was 15.15 and post-laser IOP was 17.50. The rise in IOP was normal in 82.9% and raised in 17.1%. In lower energy group normal IOP was found in 35.7% and raised in 2.9%. In a higher energy group, normal IOP was found in 47.1%, and raised IOP was found to be 14.3%. Conclusion: Higher the energy used during the Nd YAG laser posterior capsulotomy procedure, more is the chance of a rise in post-laser intraocular pressure as compared to those in which lesser energy was being used.

Background: The transient increase of intraocular pressure (IOP) following neodymium YAG laser capsulotomy can occur in a significant number of patients, which requires prophylactic treatment with IOP reducing drugs, and in some patients, postoperative IOP monitoring. This study was performed to compare the efficacy of brimonidine 0.2% versus latanoprost0.005% (Xalatan) in preventing the IOP elevation after YAG laser posterior capsulotomy in patients visiting ophthalmology clinic in Alavi Hospital.Methods: This study was a randomized, double-blind clinical trial that included 100 patients who had developed posterior capsule opacification (PCO) as a result of previous cataract surgery and were candidate for undergoing YAG laser posterior capsulotomy. The patients were randomly divided into two groups of 50 patients. One group received brimonidine 0.2% one hour before surgery, and the other group received Xalatan 0.005% in the night before laser surgery. In both groups the patients' IOP was measured in baseline, 1, 2, 3, 24 hours, 3 days and one week after surgery. The gathered data were analyzed using statistical methods in SPSS.16.Results: The mean IOP, 1, 2, 3, and 24 hours, 3 days, and one week after surgery didn't show any significant difference between two groups. IOP one hour before surgery changed significantly compared to one hour after surgery and a statistically significant relationship was found between the two groups, though at other times of measurement, the differences were not significant.Conclusions: Results showed that using Brimonidine 0.2% or Latanoprost 0.005% as prophylactic before YAG laser posterior capsulotomy could be effective in preventing IOP after treatment.

Purpose: To describe our clinical experience with the efficacy and safety of micropulse transscleral cyclophotocoagulation as a treatment for glaucoma. Methods: In this retrospective case series, we reviewed the charts of 95 consecutive patients with various glaucoma subtypes who underwent micropulse transscleral cyclophotocoagulation. Patients were offered micropulse transscleral cyclophotocoagulation if they had perimetric glaucoma refractory to intraocular pressure–lowering topical medications and who were poor candidates for traditional filtering surgery. Eligible patients were treated with the Micropulse P3 device (IQ 810 Laser Systems; Iridex, Mountain View, CA, USA) at 2.0–2.5 W for a duration of 90 s per hemisphere at a 31.3% duty cycle. If a retreatment was needed, the power was increased to up to 3.0 W with other parameters remaining the same. Patients were considered successfully treated if their intraocular pressure was lowered by at least 20% compared to their baseline. The main outcome measure was post-operative intraocular pressure; secondary outcome measures included the number of adverse events and complications that occurred with treatment. Results: The glaucoma subtypes treated included primary open-angle glaucoma (n = 51), exfoliation glaucoma (n = 24), chronic angle-closure glaucoma (n = 15), and congenital/juvenile glaucoma (n = 5). The mean pre-operative intraocular pressure was 25.1 ± 5.3 mm Hg and the mean post-operative intraocular pressure at 12 months was 17.5 ± 5.1 mm Hg (p = 0.004). The mean number of intraocular pressure–lowering medications used preoperatively was 3.0 ± 1.1; the mean number of medications used at the 12-month post-operative visit was 1.4 ± 1.0 (p = 0.03). Success with one treatment was achieved in 73 (76.8%) of patients. With multiple treatments, all patients had significant intraocular pressure–lowering compared to baseline. The maximum number of treatments received by any single patient was 5. There were no instances of prolonged intraocular inflammation or long-term hypotony. Conclusion: Micropulse transscleral cyclophotocoagulation appears to be a safe and efficacious treatment for glaucoma. Given its improved safety profile compared to continuous-wave transscleral cyclophotocoagulation, it deserves consideration as a primary procedure.

We assessed the outcomes of the use of anterior chamber foldable lens for unilateral aphakia correction at the University Teaching Hospital of Yaounde. In this retrospective, non-comparative, consecutive case series study, we reviewed the records of patients who underwent an operation for aphakia correction by the means of injection of an angular supported foldable lens between January 2009 and December 2011 in the University Teaching Hospital Yaounde. Student's paired t-test was carried out to compare preoperative and postoperative visual acuity (VA) and intraocular pressure (TOP). P-values less than 0.05 were considered statistically significant. Twenty-one patients were included in the study; twelve were male (57.1%) and nine were female (42.9%). The mean age was 55.38 ± 17.67 years (range 9–75 years). The mean follow-up duration was 5.95 ± 3.14 months (range 2–12 months). The mean logMAR visual acuity was 1.26 ± 0.46 pre-operatively and 0.78 ± 0.57 post-operatively ( P = 0.003). The change in intraocular pressure was not statistically significant. Complications included intraocular hypertension (over 21 mmHg) in 3 patients (14.3%) and macular edema, pupillar ovalization, and retinal detachment in one patient each. The results indicate that injection of an angular support foldable lens in the anterior chamber is a useful technique for the correction of aphakia in eyes without capsular support. More extended follow-up, however, and a larger series of patients are needed to ascertain the effectiveness and safety of this procedure.
