AIM: To analyze the therapeutic effect of combined ab-interno trabeculectomy and cataract surgery on intraocular pressure (IOP) levels in supine and sitting postures during a 24-hour IOP profile. METHODS: Twenty-six eyes of twenty-six patients receiving ab-interno trabeculectomy using electroablation of the trabecular meshwork combined with cataract surgery or stand-alone were included in this retrospective analysis. IOP change during 24-hour IOP profiles within two years postoperatively were analyzed for eyes receiving surgery (“study eyes”) and compared to fellow eyes, which had not received surgery. Clinical data including mean sitting IOP (siIOP), mean supine IOP (suIOP) and the number of topical antiglaucomatous medications (TAM) were extracted from patients’ files. RESULTS: Preoperatively, siIOP was 17.6±5.3 mm Hg in study and 17.1±4.7 mm Hg in fellow eyes (P=0.347). Patients were treated with an average of 2.8±1.0 TAM. Best corrected visual acuity (BCVA) was significantly worse in study eyes (P<0.001), visual field function was marginally not significantly different (P=0.057). After surgery 9.6±6.8mo, study eyes had a mean siIOP of 14.5±3.6 mm Hg (IOP reduction: -3.2 mm Hg, P=0.009), a mean suIOP of 18.0±3.5 mm Hg, and an average of 1.3±1.34 TAM (P<0.001), while in fellow eyes, mean siIOP was 16.2±3.4 mm Hg and mean suIOP was 20.5±5.1 mm Hg. Postoperatively, the relative IOP increase between sitting and supine postures was approximately 30% in both study and fellow eyes (P=0.99). CONCLUSION: IOP after ab-interno trabeculectomy shows a comparable relative reduction in both supine and sitting position. Classical trabeculectomy is known to lower suIOP overproportionally.

Abstract Background: malignant glaucoma after cataract surgery is still one of the serious complications, if not handled properly，it may lead to serious consequences. It is notoriously difficult to treat. 25G vitrectomy was performed to evaluate the safety and efficacy for the treatment of malignant glaucoma in pseudophakia. Methods: This is a retrospective, comparative case series study. A total of 20 eyes of 20 patients with malignant glaucoma after phacoemulsification were analyzed retrospectively in The First Affiliated Hospital Of Anhui Medical University from May 2015 to January 2018. All Medical Data including the best corrected visual acuity (BCVA), Change of intraocular pressure (IOP), the length of eye axis, and the depth of anterior chamber were recorded. SPSS 17.0 statistical software was used for analysis .Before surgery, the best corrected visual acuity (BCVA) was 1.8±0.6. The intraocular pressure was between 18-57mmHg, with an average of 35.2±10.4mmHg.The depth of anterior chamber was between 0.9-1.9mm, with an average of 1.3±0.2mm.The length of eye axis was 19.7-22.5mm,with an average of 20.6±0.5mm.All the patients were accomplished with 25G vitrectomy. Besides, anterior chamber inflammatory reaction and other complications were also observed postoperation. Results: The patients were followed up for 6-12 months with an average of 9 months. BCVA at the last follow up improved to 0.8±0.1, and there was significant difference compared to that before operation (P<0.01).IOP was from 12-19mmHg, an average of 16.1±2.5mmHg, there was significant difference compared to that before operation (t=7.6, p<0.01).Only one patient occurred low IOP (6mmHg) after surgery, IOP returned to normal level (14mmHg) after conservative treatment. No serious complications including corneal endothelium decompensation, intraocular lens (IOL) capture, intraocular hemorrhage, endophthalmitis and uncontrolled IOP were observed. Conclusions: 25G minimally invasive vitrectomy can treat malignant glaucoma after cataract surgery safely and effectively

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.

The aim of this study is to compare the surgical efficacy and safety between microhook ab-interno trabeculotomy (µLOT) and iStent trabecular micro-bypass stent implantation when both were combined with cataract surgery in both eyes of patients. Sixty-four glaucomatous eyes (32 participants; mean age, 75.9 ± 7.6 years; 15 men, 17 women) were included retrospectively. Intraocular pressure (IOP), number of antiglaucoma medications, best-corrected visual acuity (BCVA), anterior chamber flare (ACF) and corneal endothelial cell density (CECD) were evaluated preoperatively, as well as 2, 3, 6, and 12 months postoperatively. Surgical complications and interventions were compared between the procedures. The preoperative IOP and medications with µLOT (18.8 ± 5.7 mmHg and 3.0 ± 1.2, respectively) were higher than with the iStent (15.5 ± 3.4 mmHg and 2.7 ± 1.2, respectively) (p = 0.0001 and p = 0.0437, respectively). At 12 months, the µLOT values (12.6 ± 2.3 mmHg and 2.3 ± 0.9, respectively) were identical to iStent (12.8 ± 2.5 mmHg and 2.3 ± 0.9, respectively) (p = 0.0934 and p = 0.3251, respectively). At 12 months, the IOP decreased more with µLOT (6.2 mmHg, 29.5%) than iStent (2.7 mmHg, 15.6%) (p = 0.0003). The decrease in medications was greater with µLOT (0.7) than iStent (0.4) (p = 0.0437). Survival rate of IOP control ≤15 mmHg and IOP reduction ≥20% was significantly higher after µLOT (40.6% at 12 months) than iStent (18.8%) (p = 0.0277). The frequency of layered hyphema was significantly greater with µLOT (8 eyes, 25%) than iStent (0 eyes, 0%) (p = 0.0048). The increase in the ACF at 2 weeks postoperatively was significantly greater with µLOT than iStent (p = 0.0156), while changes in the BCVA and CECD were identical between groups. The fellow-eye comparison showed that the IOP reduction was greater with µLOT than iStent when combined with cataract surgery.

Objective- To evaluate and compare efficacy and safety of topical Difluprednate ophthalmic emulsion 0.05% with Nepafenac ophthalmic suspension 0.1% in patients of uneventful cataract surgery with respect to postoperative macular thickness and volume. Design- A prospective, single centric, tertiary care centre based, comparative, interventional study from August 2013 to July 2014 Subjects- Total 206 ( Group N=106, Group D=100) patients were followed up who completed their 12 weeks follow up Methodology- Surgery was performed by phacoemulsification technique by clear corneal incision with foldable PCIOL implantation by a single surgeon having 10 years of surgical experience. Post operative patients were divided into 2 groups. Group N were given topical treatment with Nepafenac ophthalmic suspension  0.1% TID starting 24 hours before surgery  and continued post-op 4 weeks. Group D were given Difluprednate ophthalmic emulsion 0.05% QID post surgery for 2 weeks followed by BID for 2 weeks.  Main outcome measures: Postoperative assessment of patients were done on 1st day and on 1st, 8th and12th  weeks  after the surgery for best corrected visual acuity (BCVA) by logMAR, intraocular pressure by Applanation tonometry and macular thickness and volume by SD-OCT. Statistical test used was sample Unpaired and paired ‘t’ test  and statistical analysis was done with SPSS 20.0 ( IBM, USA). Results- There was increase in the measured mean central subfield thickness( CST) at 8 and 12 weeks as compared to 1 week , in both the study groups (P<0.05). On comparing the volume (in mm3) and average thickness (in µm) at 1 week, it was observed that thickness of group N (266.82±25.06 µm) was statistically higher than that of group D (253.14±22.21µm) (P= 0.03). The comparison of best corrected visual acuity (LogMAR) and the intraocular pressure recordings showed no difference between the patients of two studied groups recorded at 1 week and 8 weeks and 12weeks. Conclusion- Both Nepafenac ophthalmic suspension 0.1% and Difluprednate ophthalmic emulsion 0.05% are equally effective in controlling macular thickness change after uneventful cataract surgery.
