Abstract Background To compare the efficacy and safety of gonioscopy-assisted transluminal trabeculotomy (GATT) and Kahook Dual Blade (KDB) excisional goniotomy in patients with uncontrolled juvenile open-angle glaucoma (JOAG). Methods Thirty-three patients (46 eyes) were included in this single-center, retrospective, comparative study and treated with GATT (36 eyes) or KDB goniotomy (13 eyes). Intraocular pressure (IOP), number of glaucoma medications, adverse events, and additional anti-glaucoma procedures were collected during pre- and postoperative visits. Surgical success was defined as 6 mmHg ≤ IOP ≤ 18 mmHg and ≥ 20% IOP reduction from baseline with (partial success) or without (complete success) IOP-lowering medications. Results The mean ± SD preoperative IOP was 30.48 ± 12.9 mmHg and 26.08 ± 13.1 mmHg (P = 0.164) on 3.71 ± 0.46 and 3.08 ± 0.86 (P = 0.023) glaucoma medications in GATT and KDB group, respectively. At 3 months, the mean ± SD IOP was 15.48 ± 5.93 mmHg and 20.0 ± 10.8 mmHg after GATT and KDB, respectively (P = 0.072). The percentage of IOP lowering from baseline was 44.4 in the GATT group and 14.1 in the KDB group (P = 0.011). The mean reduction in medications was 2.6 ± 1.7 and 0.8 ± 1.2 three months after GATT and KDB, respectively (P < 0.001). Cumulative proportion of partial and complete success were 65.6 and 44.7% in the GATT group, 30.8 and 15.4% in the KDB group at 6 months. Additional procedures were required in 13.9% of cases after GATT and in 61.5% after KDB (P = 0.001). Patients in the GATT group with prior anti-glaucoma procedures and postoperative IOP spikes were more likely to fail, while those with complete trabeculotomy had a better prognosis. Conclusions Reduction of IOP and medications were greater after GATT in uncontrolled JOAG eyes. Whereas, more additional IOP-lowering procedures were required after KDB goniotomy. Trial registration This study was registered under the Chinese Clinical Trial Registry (ChiCTR2000034172, 27/06/2020).

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.

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 Background: Glaucoma surgery have been developed to lower intraocular pressure in a less invasive manner than traditional glaucoma surgery. The purpose of this article is to determine the outcome of using combined phacoemulsification technique, ab-interno trabeculectomy dual blade and endoscopic cyclophotocoagulation (ECP) surgeries in patients with primary open angle glaucoma. Methods: A retrospective case series was performed on 27 consecutive eyes with both primary open-angle glaucoma (POAG) and cataract; each eye was treated with combined phacoemulsification, ab-interno trabeculectomy-Kahook Dual Blade and Endocyclophotocoagulation at Instituto de ojos Oftalmosalud, Lima, Peru, between April 2017 and May 2017. Inclusion criteria: 1) Patients with uncontrolled mild to advanced POAG (according to Glaucoma Grading Scale HODAPP) 2) cataract condition 3) treatment with two or more glaucoma medications due to rapid progression in the visual fields (at least two in a short period of time). Intraocular pressure (IOP), best corrected visual acuity (BCVA) logMAR and number of glaucoma medications were recorded prior to the study, at day 1, week 1, and 1,3,6 and 9 months after surgery. Primary outcome measure was surgical success defined in terms of IOP <14 mmHg either with no medications (complete success) or with medications (qualified success). Results: A total of 27 eyes from 27 patients were included. The mean basal IOP was 17.0±3.7 mmHg and postoperatively was 11.6±1.9 mmHg and 11.4±1.8 mmHg (P<0.001) at 6 and 9 months respectively. Glaucoma medications decreased from 1.9±1.4 to 0.56±1.05 at 9 month follow-ups (P<0.001). Preoperative best corrected visual acuity (BCVA) showed and improvement from 0.4± 0.4 LogMAR to 0.2 ± 0.4 logMAR at 9 months. The main complication was blood reflux intra-operatively (66.7%), which resolved without re-operation. The mean IOP was reduced by 32.9% from baseline and the surgical success was 92,6%, (complete success 70,3% and qualified success 29,6%) at 9 months.Conclusions: In patients with POAG, combined treatment with phacoemulsification, ab-interno trabeculectomy and endoscopic cyclophotocoagulation effectively reduced IOP and glaucoma medication dependence.

Purpose. To investigate the efficacy and safety of 360° selective laser trabeculoplasty (SLT) on medically uncontrolled open-angle glaucoma (OAG) and to evaluate the effects of antiglaucomatous medications on the results of therapy. Materials and Methods. The medical records of 62 eyes of 51 patients with OAG, which did not reach the targeted intraocular pressure (IOP) with maximum antiglaucomatous medical therapy, were retrospectively reviewed. Results. A statistically significant decrease was observed in the mean baseline IOP at 1, 3, 6, and 12 months of followup (P<0.01). The success rate was 64.5% in all of the patients. The success rates did not vary significantly by taking 1, 2, 3, or 4 medications with the rates of 63.6%, 71.4%, 64.2%, and 58.3% (P=0.06). The success rate of eyes on medication more or less than 6 months was 62.5% or 66.7%, respectively (P=0.3). There was a positive correlation between mean baseline IOP and mean reduction in IOP from baseline (P<0.001, r=0.8). Conclusion. Application of 360° of SLT provided an effective and safe IOP reduction in medically uncontrolled OAG. Baseline IOP was found to be the most important factor in the efficacy of therapy.

Objectives: To describe short-term efficacy of goniotomy with trabecular meshwork excision using the Kahook Dual Blade (KDB, New World Medical Inc., Rancho Cucamonga, CA) in patients with Primary Open Angle Glaucoma, (POAG) either as a standalone or plus Phacoemulsification (phaco). Method and Patients: A retrospective review of 12 eyes of 9 patients who had goniotomy with Kahook dual blade either as a standalone or combined with cataract surgery by phacoemulsification from April 2017 to July 2018 at Eye Foundation Hospital, Ikeja, Lagos. The patients were follow-up for a minimum of 6 months. Results: The mean age of the patients was 66.4±8.8 years. Mean preoperative intraocular pressure (IOP) for all eyes was 18.58±5.42mmHg. From day 1 through the 6th Month of postoperative follow-up, the mean IOP ranged from 18.58±9.26mmHg to 12.27±1.68mmHg representing reductions of 0-6.31mmHg (0-34%; p<0.05 at each time point versus baseline except for day 1). For the Phaco+KDB group, the baseline mean IOP was 19.25±4.56mmHg while the mean IOP postoperatively from day 1 to 6 months ranged from 19.13±8.99mmHg to 12.13±1.89mmHg representing reductions of 0.12mmHg to 5.13mmHg (0.6-30.2%; p<0.05 only from 1 month to 6 months). At baseline, the mean IOP for the eyes that had KDB goniotomy as a standalone was 17.25±7.45mmHg and postoperatively ranged from 17.50±11.09mmHg to 12.67±1.67mmHg representing reductions of -0.25-9.08mmHg (-1.45%-41.7%; p<0.05 at one week, 3 and 6 months only versus baseline). Conclusion: KDB either as a standalone or with phaco recorded at least 30% reduction in IOP after 6 months of followup in these series.

Purpose To evaluate the efficacy and safety of CO2-Laser Assisted Sclerectomy Surgery (CLASS) with 5-fluorouracil (5-FU) in treating open-angle glaucoma (OAG) in Chinese patients. Methods: This was a retrospective, uncontrolled, interventional case series. All patients from 2016 to 2017 who received CLASS were recruited in this study. The primary outcome was the change in intraocular pressure (IOP) and the number of IOP-lowering medications over a 12-month follow-up period. Adverse events were evaluated as secondary outcomes. Results: Data were collected from forty-two eyes of 31 patients. The average preoperative IOP was 31.33 ± 7.60mmHg. The mean percentage of IOP reduction from baseline at postoperative months (POM) 1, 3, 6, 9, and, 12 were 48.1% ± 24.6%, 51.4% ± 19.3%, 51.2% ± 17.2%, 50.9% ± 15.0%, 49.2% ± 16.3%, respectively (all P < 0.001). The number of glaucoma medications decreased from a baseline of 3.02 ± 0.81 to 0.05 ± 0.22, 0.10 ± 0.37, 0.12 ± 0.40, 0.17 ± 0.44, and 0.24 ± 0.58 at POM 1, 3, 6, 9, and 12, respectively (all P < 0.001). At POM 1, 3, 6, 9, and 12, complete success rates were 66.7%, 73.8%, 76.2%, 69.1%, and 71.4%, respectively. At POM 1, 3, 6, 9, and 12, qualified success rates were 71.4%, 82.0%, 85.3%, 83.3%, and 90.5%, respectively. Major postoperative complications include peripheral iris synechia, iris incarceration, and anterior chamber shallowing. Conclusions: CLASS with 5-FU shows safety and efficacy for decreasing IOP and the number of IOP-lowering medications over a 12-month follow-up period. It could be an alternative treatment for patients with OAG.

Glaucoma is the leading cause of irreversible blindness worldwide, with primary open angle glaucoma (POAG) accounting for the greatest number of total glaucoma cases. This study aimed to evaluate the efficacy and safety of micropulse transscleral cyclophotocoagulation (MP-TSCPC) as a primary procedure in POAG during the COVID-19 pandemic. We retrospectively analyzed 60 eyes of 52 patients, who were diagnosed with mild-to-end-stage POAG without previous glaucoma surgery and received MP-TSCPC between 1 January 2020 and 31 August 2020. The mean preoperative intraocular pressure (IOP) significantly decreased from 27.8 mm Hg to 19.8, 20.1, 20.3, 20.4, and 20.2 mm Hg at 1, 3, 6, 9, and 12 months, respectively (all p < 0.05). The mean number of IOP-lowering medications used significantly decreased from 3.3 at the baseline to 1.6, 1.8, 1.8, 1.9, and 1.9 at 1, 3, 6, 9, and 12 months, respectively (all p < 0.001). Total withdrawal of antiglaucoma medications was fulfilled in five patients. The main outcome was achieved in 81.7% at postoperative month 12. The most common adverse effect was transient mydriasis (28.3%). No major complications were encountered. MP-TSCPC seems to be an effective and safe treatment to reduce IOP and the medication burden with minimal vision-threatening complications in mild-to-end-stage POAG patients without previous glaucoma surgery.
