Background: We evaluated the safety and efficacy of endoscopic cyclophotocoagulation (ECP) for eyes with primary open-angle glaucoma (POAG). Methods: We included a total of 104 pseudophakic eyes treated with ECP. Visual acuity and intraocular pressure (IOP, mmHg) measurements were evaluated preoperatively and on days 1 and 7 and 2 and 12 months postoperatively. IOP ≤ 15 or ≥30% reduction from baseline were defined as therapeutic success. Results: The mean baseline IOP was 23.89 ± 8.63, and it decreased significantly at the day 1 (16.25 ± 7.32, p < 0.0001), day 7 (17.81 ± 6.37, p < 0.0001), 2nd month (17.77 ± 8.54, p < 0.0001) and 12th month (16.42 ± 7.05, p < 0.0001) follow-up visits. Therapeutic success was achieved in 55 (61.80%) eyes at the 12-month follow-up. Patients with POAG duration longer than 10 years or those using alpha agonist eye drops had a lower rate of therapeutic success (odds ratio: 0.52, 95% CI = 0.32–0.85, p < 0.05 and odds ratio: 0.92, 95% CI = 0.55–0.95, p = 0.024, respectively). A longer disease course was associated with higher IOP values (Rs =+0.281; p = 0.024) postoperatively. The number of antiglaucoma medications decreased significantly from 2.55 ± 1.16 to 2.11 ± 1.14 (p = 0.003). The ECP complications included a minor IOP increase (9.37%), pupil irregularity (15.73%), and the presence of fibrin (3.29%). Conclusions: The ECP is an effective and safe option, especially in eyes with a shorter glaucoma course.

Background: The most common treatment for primary open-angle glaucoma (POAG) is the daily use of eye drops. Sustained-release drug delivery systems have been developed to improve patient adherence by achieving prolonged therapeutic drug concentrations in ocular target tissues while limiting systemic exposure. The purpose of this study is to compare the efficacy and safety of bimatoprost inserts with bimatoprost eye drops in patients with POAG and ocular hypertension (OH). Methods: We include OH and POAG patients aged between 40 and 75 years-old. Both OH and POAG patients had intraocular pressure (IOP) greater than 21 and ≤30 mmHg at 9:00 am without glaucoma medication and normal biomicroscopy. Five normal patients with IOP≤14 mmHg constitute the control group. A chitosan-based insert of bimatoprost was placed at the upper conjunctival fornix of the right eye. In the left eye, patients used one drop of LumiganTM daily at 10:00 pm. For statistical analysis, we used a two-way analysis of variance (ANOVA), Student t-test, and paired t-test. Results: Sixteen POAG and 13 OH patients with a mean age of 61 years were assessed. In both eyes, IOP reduction was similar during three weeks of follow-up (19.5±2.2 mmHg and 16.9±3.1 mmHg), insert, and eye drop, respectively; P=0.165). The percentage of IOP reduction in the third week was 30% for insert and 35% for eye drops (P=0.165). No intolerance or discomfort with the insert was reported. Among the research participants, 58% preferred the use of the insert while 25% preferred eye drops, and 17% reported no preference. Conclusions: Bimatoprost-loaded inserts showed similar efficacy to daily bimatoprost eye drops during three weeks of follow up, without major side effects. This might suggest a possible change in the daily therapeutic regimen for the treatment of POAG and OH.

Purpose: The aim of this study is to compare the outcomes of micropulse transscleral cyclophotocoagulation between primary open-angle glaucoma, pseudoexfoliation glaucoma, and other types of secondary glaucoma. Methods: Outcomes of 96 consecutive patients with refractory, end-stage glaucoma treated with micropulse transscleral cyclophotocoagulation were retrospectively reviewed. Follow-up examinations were performed on a regular basis until 12 months postoperatively. Surgical successes were defined as maintaining intraocular pressure ⩽18 mmHg and ⩾20% reduction in intraocular pressure (criteria A), ⩽15 mmHg intraocular pressure and ⩾25% reduction in intraocular pressure (criteria B), and ⩽12 mmHg intraocular pressure and ⩾30% reduction in intraocular pressure from baseline (criteria C). Results: Ninety-six eyes of 96 patients (50 (52%) females, 46 (48%) males) were included. Among all eyes, 32 were primary open-angle glaucoma, 30 were pseudoexfoliation glaucoma, and 34 were other types of secondary glaucoma. The mean age was 59.37 ± 11.45 (range: 20–91) years. The mean follow-up period was 14.2 ± 3.9 (range: 12–16) months. At 12 months, the success rates of primary open-angle glaucoma, pseudoexfoliation glaucoma, and secondary glaucoma group were 68.75%, 66.6%, and 64.7% (p = 0.185) for criteria A; 56.25%, 53.3%, and 50% (p = 0.153) for criteria B; and 43.75%, 43.3%, and 38.2% (p = 0.146) for criteria C. Four patients (12.5%) in primary open-angle glaucoma group, 5 patients (16.6%) in pseudoexfoliation glaucoma group, and 14 (41.2%) patients in other secondary glaucoma group required reoperation during the follow-up (p < 0.05). Conclusion: Micropulse transscleral cyclophotocoagulation is an equally effective method of lowering intraocular pressure in patients with primary open-angle glaucoma, pseudoexfoliation glaucoma, and other types of secondary glaucoma. The rate of reoperation was higher in refractory secondary glaucoma patients.

Primary open angle glaucoma is the most common form of glaucoma and it remains asymptomatic until the late stage of the disease. The purpose of this study is to compare the mean ocular perfusion pressure with the primary open angle glaucoma. A total of 60 study subjects were divided into two following groups: a) newly diagnosed patients with primary open angle glaucoma (case) and b) age and sex-matched healthy volunteers (control). The intraocular pressure and blood pressure were measured 3 hourly from 8:00 am to 11:00 pm. The mean ocular perfusion pressure of the right eyes in untreated primary open angle glaucoma was 39.9 ± 7.5 mm Hg whereas it was 47.7 ± 7.7 mm Hg in the control. The odds ratio was 6.6 (95% CI, 2.1-20.5; p=0.002). The right eyes of untreated primary open angle glaucoma had 6.6 times more risk compared to the control group. The mean ocular perfusion pressure of left eyes in untreated primary open angle glaucoma was 39.9 ± 7.5 mm Hg and 48.6 ± 4.0 mm Hg in the control group. The odds ratio was 5.7 (95% CI, 1.8-17.5; p=0.004). The left eyes of untreated primary open angle glaucoma had 5.7 times more risk compared to control group. The findings revealed the evidence of vascular mechanism in glaucoma pathogenesis: Reduction of mean ocular perfusion pressure ≤48 mm Hg, may lead to daily repetitive ischemic insult to the optic nerve.

PurposeTo characterise the genotype(s), phenotype(s) and age-related penetrance of glaucoma in a Chinese family with primary open-angle glaucoma (POAG).MethodsRecruited from a Chinese family spanning four generations, 7 individuals with POAG, 1 with ocular hypertension (OHT) and 14 unaffected individuals were included in this study. Genotypic investigation included sequencing of mutation sites using a glaucoma panel in combination with high-throughput sequencing and validated using Sanger sequencing. Phenotypic characterisation included investigation into patient medical history and physical examination.ResultsEight (36.4%) family members harboured heterozygous Y437H mutation, of whom seven (87.5%) were glaucomatous and one (12.5%) had OHT. The mean age of POAG diagnosis was 30.85±7.13 years. The mean highest recorded intraocular pressure (IOP) was 46.57±6.53 mm Hg. They all had complained of symptoms associated with vision and pain. Four (57.1%) patients presented blindness. Five eyes (62.5%) presented with severe and three eyes with moderate visual field defects. Most of them underwent surgery on average 1.29±2.36 years after diagnosis, and the mean IOP at study was 17.95±7.23 mm Hg, with an average of 0.92±0.86 eye-drops. The patient with OHT was treated with latanoprost only and her IOP was well controlled. Age-related glaucoma penetrance was 0% in individuals under the age of 20 years, 50% at ages 20–35 years, 75% at ages 31–35 years and 87.5% over 45 years.ConclusionA novel MYOC mutation (c.1309T>C, p.Y437H) in a Chinese family with POAG was identified which was associated with a phenotype characterised by severe visual impairment, frequent surgical intervention requirement and relatively high penetrance.

Purpose: To compare the efficacy and safety of bimatoprost (0.03 %) and travoprost (0.004 %) in patients with primary open angle glaucoma (POAG). Subjects and methods: Patients with POAG were randomized to receive either bimatoprost or travoprost once daily. Detailed ocular examination was done and intraocular pressure (IOP) was measured at 9.00 am, 1.00 pm and 4.00 pm at the baseline and at 1, 2, 4, 6 and 12 weeks of therapy. Results: A total of 31 patients were analysed. The patients were randomly divided into two groups (Bimatoprost group = 16; Travoprost group = 15). Both the groups had a statistically significant reduction from the baseline IOP at all follow up visits at 9.00 am, 1.00 pm and 4.00 pm. The mean IOP decreased from a baseline of 25 ± 2.32 mm Hg to 15.93 ± 1.79 mm Hg after 12 weeks in the bimatoprost group (p < 0.001), and from 24.2 ± 1.60 mm Hg to 16.53 ± 1.56 mm Hg in the travoprost group (p < 0.001). A better mean reduction of IOP was obtained with bimatoprost than with travoprost at the end of the study at 12 weeks (p = 0.03). Mild ocular redness was the commonest side effect in both the groups but was not significant in either group. Conclusion: Both drugs lowered IOP effectively but bimatoprost showed a greater reduction in the mean IOP than did travoprost at 12 weeks and both are safe for ocular use.

AIM: To evaluate the safety and efficacy of augmented trabeculotomy with Ologen versus perfluoropropane in management of pseudophakic glaucoma. METHODS: This is a comparative randomized study included 57 pseudophakic eyes of 57 patients with medically uncontrolled open angle glaucoma (OAG). Twenty-nine patients were allocated in group I (trabeculectomy with Ologen; trab-ologen group), while 28 patients were assigned in group II (trabeculectomy with perfluoropropane gas bubble; trab-C3F8 gas bubble group). RESULTS: The intraocular pressure (IOP) was significantly reduced in both study groups at all postoperative follow up intervals (1wk, 3, 6, 12, 18, 24, 30 and 36mo, P&#x0026;#x003C;0.001). The differences between the mean IOP values of both groups remained statistically insignificance during the early 12 months of follow up. However, the trab-ologen group achieved a statistically significant reduction over the trab-C3F8 gas bubble group during the last 24 months of follow up. CONCLUSION: Augmentation of trabeculectomy with either Ologen implant or perfluoropropane gas bubble are associated with strict long term IOP control and evident safety in medically-uncontrolled pseudophakic eyes with OAG.

Purpose: To compare the therapeutic efficacy and safety of dorzolamide/timolol fixed-combination in newly diagnosed primary open angle glaucoma patients. Methods: In this prospective, interventional case series, newly diagnosed primary open angle glaucoma (POAG) patients that had not been treated for glaucoma were included. Patients were started on Cosopt twice a day (BID) for 1 month and then switched to three times a day (TDS) for additional 1 month. Patients underwent comprehensive ophthalmic examination, diurnal intraocular pressure (IOP), blood pressure (BP) and 24-hours heart rate (HR) measurements at baseline, month 1( BID), and month 2( TDS). IOP, systolic and diastolic pressures were measured at 8:00 AM,12:00 AM, 4:00 PM, 8:00 PM and 12:00 PM. Throughout the study, all adverse events were recorded and monitored by the investigators. Results: In 31 POAG patients that completed the study ,mean baseline IOP was 23.1&plusmn;3.15 mmHg . IOP was decreased significantly 16.5 &plusmn; 2.21 at 1 month (P &lt; 0.0001) and 13.9 &plusmn; 2.23 mmHg at 1 and 2 month follow up. (P &lt; 0.0001) IOP was significantly lower in month 2 compared to month 1 (P = 0.0004). While Cosopt BID significantly reduced the mean 24-hour systolic BP and mean 24-hour HR from baseline (P &lt; 0.0001), the mean 24-hour systolic BP and HR remained unchanged 2ith Cosopt TDS compared to BID (P = 0.62). Conclusions: Cosopt TDS has a superior IOP-lowering effect than Cosopt BID in POAG patients with comparable safety profile.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;

ABSTRACT Objective: To compare levobunolol and travoprost for lowering the intra-ocular pressure (IOP) in patients of ocular hypertension and primary open-angle glaucoma. Materials and Methods: A Quasi experimental study was conducted in the ophthalmology department of Khyber Teaching Hospital, Peshawar. 120 patients of both genders and age between 18-80 years with ocular hypertension or primary open angle glaucoma requiring single pressure lowering drug were enrolled in the study. Subjects were divided into two groups (60 in each). One group was treated with travoprost eye drops (0.004%, OD) while other group with levobunolol eye drops (0.5%, OD). After initial screening visit where demographic data and baseline IOP was recorded on structured proforma, three follow-up visits were arranged each at 02 weeks interval. At each follow-up visit, IOP was recorded by standard protocols to evaluate and compare the ocular hypotensive efficacy of study drugs by calculating mean IOP change from the baseline. Only patients with no missing IOP measurements for all visits were considered eligible for the efficacy evaluation. Results: A total of 120 patients were observed having age range from 18 years and above with mean age 52.16 ± 9.56 and predominance of male gender. Upon comparative analysis, no significant statistical difference (p value >0.05) was observed in the ocular hypotensive efficacy of levobunolol and travoprost measured at each follow-up visit, indicating both the drugs equally effective. Moreover, age groups did not reveal any significant statistical impact on the treatment outcome of patients treated with either study drug. Conclusion: Though both the drugs are equally effective, levobunolol is better option than travoprost for the treatment of glaucoma because of its fast onset of action, cost effectiveness and easy availability.

AIM: To describe the safety and efficacy of patterned laser trabeculoplasty (PLT) as an adjunctive treatment in primary open angle glaucoma (POAG) and ocular hypertension (OHT) after 18-month follow-up in Hispanic population. METHODS: A single-center, retrospective study was conducted. All patients with OHT or POAG undergoing PLT from June 2016 to August 2016 were included in the study. Investigated parameters were intraocular pressure (IOP), the number of IOP-lowering medications, best corrected visual acuity (BCVA), laser parameters and postoperative adverse events. Primary efficacy outcome measures were the proportion of eyes achieving an IOP reduction ≥20% at 18mo versus baseline medicated IOP or a reduction in the number of medications while maintaining IOP values. RESULTS: From 40 PLT-treated eyes (mean baseline IOP 20.3±1.7 mm Hg), 24 patients were analyzed (age 63.4±7.3y). The mean IOP reductions from baseline across visits (months 1, 3, 6, 9, 12, and 18) ranged from 14.1% to 20.8%. Success rate after 18-month follow-up was 61.7% with a mean IOP of 16±3.2 mm Hg (P<0.001). The number of glaucoma IOP-lowering medications per eye (preoperative 2.1±1.1 and postoperative 2.3±1.1, P=0.86) and the mean BCVA (preoperative 0.10±0.22 and postoperative 0.11±0.22 logMAR, P=0.42) remained stable. Adverse events comprised transitory IOP spikes in 4 eyes (10%) and peripheral anterior synechiae in 7 eyes (17.5%). CONCLUSION: Mid-term results of PLT show that this procedure may be an efficacious and safe technique to approach medically uncontrolled OHT or POAG patients.
