Purpose:  To determine the outcomes of conventional trabeculectomy in terms of decrease in Intra Ocular Pressure (IOP) and improvement in visual acuity in patients of primary open glaucoma, coming to a tertiary care hospital. Study Design:  Retrospective case series. Place and Duration of Study:  Ophthalmology department of a tertiary care hospital from January 2017 to December 2018. Methods:  Patients undergoing trabeculectomy for Primary open angle glaucoma were included. Patients with repeated trabeculectomy, failed argon laser trabeculoplasty, advance cataract, corneal opacities and absolute glaucoma were excluded. All the trabeculectomies were done under retrobulbar anaesthesia after taking all aseptic measures. Primary outcome measures were preoperative and postoperative visual acuity, intraocular pressure, number of antiglaucoma medications and failed or successful trabeculectomy. Results:  Total 52 patients underwent trabeculectomy. There were 36 (69.2%) males and 16 (30.8%) females. Mean age was 56.73 years ± 10.9 SD. Mean preoperative IOP was 30.96 ± 6.71 mm Hg, post operatively IOP at 1 year it was 15.6 ± 4.2 mm Hg. P value was <.000. Mean number of antiglaucoma medications was 3.03 and 1.19, pre and post-operatively respectively (p value <.000). Improvement in visual acuity after trabeculectomy was seen in 32 (61.5%) patients. Complete Surgical success was seen in 28 (53.8%) and qualified success in 21 (40.4%) patients. Failed trabeculectomy was seen in 3 (5.8%) patients. Conclusion:  Conventional trabeculectomy is effective in lowering IOP in primary open angle glaucoma patients. It maintains IOP within normal range with and without anti-glaucoma medications at 1 year follow-up. Trabeculectomy significantly reduces number of anti-glaucoma medications. Key Words:  Intraocular pressure, Primary open angle glaucoma, Trabeculectomy.

To study the efficacy of Timolol Maleate Vs Timolol-Brimonidine combination in lowering the intraocular pressure (IOP) in primary open angle glaucoma (POAG) at a tertiary care hospital. To study any adverse effects of both drug therapies in treatment of POAG. Computerized simple randomization was followed in allocating the patients for the two groups. In each group, n=20, is the total number of patients, and N=30, is the total number of eyes tested, since both eyes were involved in some patients. The concentration of the monotherapy was 0.5% w/v Timolol Maleate and concentration of the combination therapy was 0.2% w/v Brimonidine Tartrate and 0.5% w/v Timolol Maleate. Both drugs were administered twice daily and IOP was recorded every 3 days, for a period of 4 weeks. Monotherapy of Timolol is seen to lower the IOP at 25% in 3 days, whereas the Timolol-Brimonidine combination therapy lowers the IOP at twice the rate that is 50% in 3 days. After reaching a IOP of 12mmHg, which is the normal IOP, both the drugs are used for maintenance therapy. Adverse effects were reported with both groups. Timolol monotherapy is also priced lower, when compared to Timolol-Brimonidine combination therapy. Timolol monotherapy provides the same result as the Timolol-Brimonidine combination therapy and is also comparatively cheaper. Hence, Timolol monotherapy is better suited for the treatment of POAG.

Purpose: To find the visual outcome of ocular trauma presenting in a tertiary care hospital in Sahiwal. Study Design: Descriptive observational study. Place and Duration of Study: This study was conducted at District Headquarter Teaching Hospital affiliated with Sahiwal Medical College, Sahiwal from January 2016 to June 2019. Material and Methods:  Four hundred and thirty five patients were included in the study by convenient sampling technique. Patient’s age, gender, occupation, activity at the time of injury, nature of object causing trauma, duration of trauma, visual acuity at the time when patient reported to hospital, the time delay before coming to the hospital were recorded. Ocular injuries were classified according to Birmingham ocular trauma terminology. Detailed ocular examination was performed. Patients were managed and post-management visual acuity at three months was recorded. Results: Mean age of patients was 29.07 ± 12.53 years. There were 219 (50.3%) closed globe and 216 (49.7%) open globe injuries. In 59 (13.6%) cases, cause of injury was metal object. In 146 (33.6%) cases injury was classified as contusion. In 164 (37.7%) cases cornea was involved. Majority of the patients were male. Eighty-seven patients presented within 1 day after trauma. In 154 (35.4%) patients, visual acuity at the time of presentation was 6/12 or better while in 171 (39.3%) cases it was less than 6/60. Chi-square test was used to calculate the difference between pre and post-management visual acuity. This difference was statistically significant with p-value less than 0.05 Conclusion:  Ocular trauma cases, if properly and timely managed, have a statistically significant increase in visual acuity.

Purpose. To evaluate thein vivochanges in Schlemm’s canal (SC) and the trabecular meshwork (TM) in patients with primary open-angle glaucoma (POAG) after phacocanaloplasty using anterior segment optical coherence tomography (AS-OCT).Methods. Ten eyes of nine patients with POAG (6 men and 3 women) who underwent phacocanaloplasty. Preoperative and postoperative visual acuity (VA), intraocular pressure (IOP), and use of glaucoma medications were evaluated. The main outcome measures were the area of SC and TM thickness assessed using AS-OCT before and 12 months after surgery.Results. We found statistically significant reduction in IOP (from 26.4 (8.6) mmHg to 12.9 (2.5) (p<0.05) mmHg), increase in VA from 0.7 (0.4) to 0.9 (0.2), and decrease in glaucoma medication from 2.6 (1.2) to 1.1 (1.3) at 12 months postoperatively. There was a significant increase in the SC area (3081.7 (842.8) μm2versus 5098.8 (1190.5) μm2,p<0.001) and a decrease in mean TM thickness (91.2 (18.6) μm versus 81.3 (15.1) μm,p=0.001) after surgery. We found negative correlations between SC area and IOP before surgery (r=-0.67,p=0.03) and also between SC area before and IOP reduction 12 months after the phacocanaloplasty (r=-0.80,p=0.005).Conclusions. Our results showed statistically significant dilation of SC area and reduction of TM thickness after phacocanaloplasty in POAG patients. The degree of SC expansion was related to the IOP decrease.

The purpose of this study was to evaluate the location and pattern of visual field defects as measured by Humphrey Field Analyzer (HFA 24-2) in newly diagnosed primary open angle glaucoma (POAG) attending tertiary care hospital. This was a cross sectional, descriptive study. One hundred and four eyes of 52 patients who fulfilled the inclusion criteria during one year were included. They were classified as mild, moderate and severe glaucoma according to severity. Paracentral scotoma in superotemporal and superonasal region was the most frequent visual field defect observed in mild glaucoma. Superior arcuate defect and double arcuate defect was commonly seen among moderate and severe stages of POAG respectively. There was a significant association between severity of glaucoma and pattern of visual field defect (p=0.000). The superior hemifield was affected twice more than the inferior hemifield in newly diagnosed cases of POAG.

The aim of this work was to identify risk factors for the occurrence of primary open-angle glaucoma in patients with diabetic retinopathy and type 2 diabetes mellitus by conducting a regression analysis of the mutual influence of these diseases. We examined 649 patients (649 eyes), among whom 301 patients (301 eyes) had diabetic retinopathy and glaucoma; 164 patients (164 eyes) had diabetic retinopathy only; 81 patients (81 eyes) had only glaucoma and 103 patients (103 eyes) did not have these diseases (control). The construction of logistic regression models was carried out in the GLZ module of the Statistica 10 software (StatSoft, Inc. USA). It was found that the development of primary open-angle glaucoma directly depended on the duration of diabetes and the intraocular pressure level, and vice versa — on visual acuity (p < 0.001). The development of diabetic retinopathy did not depend on the presence of glaucoma, but it was directly dependent on the blood content of glucose and glycated hemoglobin. Men had a lower risk of developing diabetic retinopathy than women(OR = 0.800; 95% CI 0.76-0.84). Also, men had a lower risk of glaucoma (OR = 0.95; 95% CI 0.94–0.96). Stratification by stages of diabetic retinopathy showed the effect of intraocular pressure, decreased visual acuity and glaucoma stages on the development of proliferative diabetic retinopathy (p < 0.001). Increased intraocular pressure was an independent factor in the development of retinopathy. The development of glaucoma of the initial stage was directly influenced by an increase of blood glycated hemoglobin and by the stage of diabetic retinopathy. The occurrence of stage 2 glaucoma was influenced by the duration of diabetes and visual acuity, stage 3 glaucoma — by visual acuity, and stage 4 glaucoma – by the age and duration of diabetes. Independent risk factors for glaucoma were duration of diabetes, increased intraocular pressure, and low visual acuity. When stratified by stage, there was no evidence of a reduction in the risk of developing diabetic retinopathy and glaucoma in men. Thus, the features of the mutual influence of the development of diabetic retinopathy and primary open-angle glaucoma in type 2 diabetes mellitus have been established.
