Comparison of Surgical Outcomes of Sponge Application versus Subconjunctival Injection of Mitomycin-C during Combined Phacoemulsification and Trabeculectomy Surgery in Asian Eyes. J Curr Ophthalmol 2021; 33:253-259. [PMID: 34765811 PMCID: PMC8579788 DOI: 10.4103/joco.joco_57_20] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2020] [Revised: 07/03/2021] [Accepted: 07/03/2021] [Indexed: 11/17/2022] Open
Abstract
Purpose: To compare the outcomes of combined phacoemulsification–trabeculectomy surgery with intraoperative sponge-applied versus subconjunctival injection of mitomycin-C (MMC) in Asian eyes. Methods: This was a retrospective review of 95 eyes that consecutively underwent combined phacoemulsification–trabeculectomy surgery in a tertiary eye center in Singapore from January 2013 to June 2014. Data collected included intraocular pressure (IOP), best corrected visual acuity, and number of glaucoma medications. Outcome measures included postoperative IOP and complications at various timepoints up to 12 months after surgery. Results: Twenty eyes (21.1%) received 0.2 mg/ml subconjunctival MMC injection (“Group 1”) and 75 (78.9%) received 0.4 mg/ml sponge-applied MMC (“Group 2”). There was no difference between groups in demographics, IOP, and number of glaucoma medications preoperatively. There was a reduction in IOP at postoperative month (POM) 1, 6, and 12 in both the groups (POM12: Group 1, −2.8 ± 5.36 mmHg, P < 0.001; Group 2, −5.8 ± 6.29 mmHg, P = 0.054). At POM1, Group 2 showed a trend toward greater IOP reduction (−5.89 ± 7.67 mmHg vs. −1.55 ± 5.68 mmHg, P = 0.061). However, at both POM6 and POM12, there was no statistically significant difference in IOP reduction between the two groups. At POM12, complete success, defined as achieving an IOP of between 6 and 15 mmHg without the use of antiglaucoma medications, was achieved in 11 (55%) eyes in Group 1 and 48 (64%) in Group 2 (P = 0.9). There was a lower rate of postoperative hypotony in the Group 1 (0%) compared to Group 2 (8%) (P = 0.34). Conclusion: Combined phacoemulsification–trabeculectomy with subconjunctival MMC injection has comparable outcomes to that with sponge-applied MMC, with a similar reduction in IOP at 1, 6, and 12 months postoperatively and a lower postoperative complication rate.

Abstract
Purpose To objectively evaluate surgically induced astigmatism (SIA) after phacotrabeculectomy using keratometry and topography and to compare the magnitude of SIA and the refractive outcomes of single-site and twin-site phacotrabeculectomies. Methods Forty prospective subjects were enrolled in the study and were randomized into single-site and twin-site cohorts. SIA was objectively assessed using keratometry and Orbscan before and at three months after surgery. For both cohorts, the changes in SIA were assessed using power vector analysis compared at the third month after surgery. Results Each cohort consisted of 20 eyes. The preoperative parameters and postoperative IOP were comparable and similar, respectively, in both the cohorts (P = 0.1). Majority of the patients in both the cohorts had preoperative against-the-rule (ATR) astigmatism. The median change in SIA at the three-month postoperative visit was similar in both the cohorts, with a small increase in ATR astigmatism. Although the SIA change measured by keratometry in the J0 component was similar in both the groups (P = 0.54), that of J45 was significantly different (P = 0.01). However, the median change in SIA was similar in both the groups for both the J0 (P = 0.52) and J45 components (P = 0.94) when measured by Orbscan. The SIA in both the groups measured with keratometry (P = 0.62) and topography (P = 0.52) were clinically and statistically similar. In both the groups, the refraction was similar at 1 month and 3 months. Conclusion The SIA as measured with keratometry and topography was similar in the single-site and twin-site phacotrabeculectomy cohorts at the end of 3-months. The postoperative refraction was stabilized in 1-month in both the groups.

Abstract
AIMS To investigate the effect of intracameral triamcinolone acetonide (TA) on surgical success in 5-fluorouracil (5-FU) supported primary phacotrabeculectomy (PT) cases. MATERIAL AND METHODS This retrospective study included 23 eyes (study group) of 23 patients who underwent TA during PT and 26 eyes (control group) of 26 patients without TA. PT patients in the study group received 1 mg TA intraoperatively at the end of surgery. Pre- and postoperative visual acuity, intraocular pressure (IOP), and number of antiglaucoma drugs used were compared. Postoperative complications and need for 5-FU injection were evaluated for both groups. RESULTS Mean age was 64.1 2 ± 1.91 (48-86) years in the control group and 66.52 ± 2.02 (52-86) years in the study group (p = 0.824). Comparison of pre- and postoperative IOP values showed significant decreases in postoperative IOP levels at all-time points in both the control and study groups (p < 0.001). The only significant difference between groups was on postoperative first day (study group: 9.22 ± 1.41 mmHg; control group: 6.35 ± 2.17 mmHg, p < 0.001). Need for postoperative 5-FU injection was significantly more common in the control group (p = 0.023). CONCLUSION Intracameral injection of 1 mg TA at the end of PT surgery did not yield superior results in postoperative IOP compared to PT alone, and the two groups showed similar IOP reduction. When given as an adjunct to PT, 1 mg TA suppresses anterior segment inflammation and reduces the need for 5-FU injection.

Abstract
AIM To compare efficacy of coaxial microincisions (1.8 mm, 2.2 mm) and small incisions (3.0 mm) on phacoemulsification combined with trabeculectomy for primary angle-closure glaucoma (PACG) with cataract. METHODS Ninety-six patients (96 eyes) with PACG and cataract were recruited and randomly divided into three groups between January 2015 and June 2017. Group A (3.0 mm incision), B (2.2 mm incision), and C (1.8 mm incision) comprised 30, 34 and 32 eyes respectively. All cases were treated with clear corneal incision phacoemulsification combined with trabeculectomy. Data including best corrected visual acuity (BCVA), corneal astigmatism, corneal endothelial cell counts (CECC), intraocular pressure (IOP), and complications were collected before the operation, and at postoperative 1d, 1 and 3mo. RESULTS All the patients were successfully treated with surgery. The BCVA of groups B and C were significantly improved as compared to group A at postoperative 1d, 1 and 3mo (all P<0.05), but there was no difference between groups B and C at each time interval (all P>0.05). The corneal astigmatism of group A was statistically higher than that of group B (P=0.026); corneal astigmatism of group B was statistically higher than that of group C at postoperative 1d (P=0.006). The corneal astigmatism of group A at postoperative 3mo was significantly higher than that before operation (P=0.003). At postoperative 1 and 3mo, corneal astigmatism of groups B and C were significantly lower than that of group A (all P<0.05). The CECC in group B was significantly higher than that of group A (P=0.020), and CECC in group C was significantly higher than that of group B (P=0.034) at postoperative 1d. At postoperative 1 and 3mo, CECC of groups B and C were significantly higher than that of group A (all P<0.05). In each group, postoperative mean IOP at each time interval was significantly lower than preoperative IOP (all P<0.05). CONCLUSION Coaxial microincision phacoemulsification combined with trabeculectomy for PACG with cataract has better curative efficacy in reducing postoperative corneal astigmatism and corneal endothelial cell injury than traditional small incision combined surgery, and the 1.8 mm microincision has better curative efficacy than 2.2 mm microincision in the early postoperative period.

Abstract
Phacotrabeculectomy is the preferred surgical management of coexisting visually significant cataract and moderate to advanced glaucoma. We report the surgical technique of a new modified fornix-based separate-site phacotrabeculectomy, with mitomycin C (MMC) application, in both primary open angle and angle closure glaucoma. In this new separate-site technique, both phaco and filtration are accommodated superiorly, side by side, hence called twin-site. This was achieved in an efficacious and safe manner with sparing of limbal stem cells without compromising safety. It is not only MMC-compatible but also has a low incidence of wound leak. The technique has no adverse consequence on the survival of the bleb, and we achieved complete success in 79.2% and total success in 93.1% in 130 eyes of 117 patients, in the intermediate term. Furthermore, the time taken for this separate-site surgical technique is comparable to published one-site procedures.

Abstract
Purpose To evaluate outcomes and factors associated with surgical failure in patients who underwent combined phacoemulsification and Ahmed glaucoma valve (AGV) implantation. Methods This retrospective and longitudinal study enrolled 40 eyes (38 patients) that underwent combined phacoemulsification and AGV implantation. Visual acuity, intraocular pressure (IOP), and number of antiglaucoma medications were evaluated preoperatively and postoperatively. Complete success was defined as a last follow-up IOP of 6 to 21 mmHg without medication, qualified success as an IOP of 6 to 21 mmHg with medication, and failure as an IOP of >21 or <6 mmHg. Results The mean follow-up period was 18 ± 10 months. Preoperative diagnoses were chronic angle closure glaucoma (35.0%), neovascular glaucoma (22.5%), uveitic glaucoma (17.5%), primary open-angle glaucoma (15.0%), and other (10.0%). IOP decreased from a mean of 30.5 ± 8.7 to 14.5 ± 3.7 mmHg at the last follow-up visit (p < 0.001). Treatment was classified as qualified success in 18 eyes (45%), complete success in 15 (37.5%), and failure in seven (17.5%). Twenty-two eyes (55%) showed improvement in visual acuity. The most common postoperative complication was a transient hypertensive phase (five eyes, 12.5%). Tube-iris touch was associated with surgical failure (hazard ratio, 8.615; p = 0.008). Conclusions Combined phacoemulsification and AGV implantation is an effective and safe surgical option for patients with refractory glaucoma and cataract. Postoperative tube-iris touch is an indicator of poor prognosis.

Abstract
PURPOSE To evaluate the efficacy of polyglactin use along with nylon suture in scleral tunnel closure after single-site phacotrabeculectomy. METHODS This retrospective case series included 139 eyes of 139 patients who had scleral tunnel closure with 1 polyglactin and 1 nylon suture after single-site phacotrabeculectomy with a low dose of mitomycin C between 2002 and 2005. The intraocular pressure (IOP), the visual acuity, the number of glaucoma medications, postoperative complications, and interventions were the outcomes measured. RESULTS The majority of them had primary open-angle glaucoma (93 eyes, 67%), 93 eyes (67%) had severe glaucomatous optic neuropathy, and 77 eyes (55.3%) had severe visual-field loss. The IOP decreased from a mean preoperative value of 18.1±5.3 mm Hg on a mean number of 1.8±0.8 glaucoma medications to mean IOPs of 13.3±4.6, 14.0±4.3, and 11.8±3.9 mm Hg on a mean number of 0.2±0.6, 0.3±0.7, 0.5±1.0 glaucoma medications (P<0.001) at 1-, 3-, and 5-year follow-up visits, respectively. An IOP of <21 mm Hg with or without medication was achieved in 96±2% at 1 year, in 88±4% at 3 years, and in 73±8% at 5 years. Shallow anterior chamber was the most common early postoperative complication (3 eyes, 2.1%). Nylon suturelysis with laser was performed in 16 eyes (11.5%). CONCLUSIONS The technique used here seems to be effective in controlling the IOP and has very minimal associated complications.

Abstract
Objective To evaluate the efficacy and tolerability of limbus-based (LBCF) compared with fornix-based conjunctival flaps (FBCF) for trabeculectomy in the treatment of patients with uncontrolled glaucoma. Methods A comprehensive literature meta-analysis was performed according to the Cochrane Collaboration methodology to identify controlled clinical trials comparing LBCF with FBCF in trabeculectomy. The efficacy measures were the weighted mean differences (WMDs) for intraocular pressure reduction (IOPR), the reduction in glaucoma medications, and the relative risks (RRs) for success rates. Tolerability estimates were measured by RR for adverse events. The pooled effects were calculated using the random effects model. Results Sixteen controlled clinical trials meeting the predefined criteria were included in the meta-analysis. A total of 1,825 eyes from 1,392 patients with medically uncontrolled glaucoma were included. The WMD of the IOPR from baseline was 1.12 (95% CI: −0.88 to 3.12) when comparing LBCF with FBCF. LBCF was associated with numerically greater but non-significant IOP lowering efficacy than FBCF (P = 0.270). LBCF was comparable with FBCF in the reduction of glaucoma medication, with a WMD of 0.15 (−0.05 to 0.36) at the follow-up endpoint (P = 0.141). The pooled RR comparing LBCF with FBCF were 1.08 (0.94, 1.23) for the complete success rate and 1.01 (0.92, 1.10) for the qualified success rate. Rates of adverse events did not differ significantly between LBCF and FBCF. Conclusions There is no significant difference in IOP lowering, number of glaucoma medications, or proportion of patients who reached the IOP target between LBCF and FBCF trabeculectomy. Both incision techniques may contribute equally to adverse events.

Abstract
PURPOSE To evaluate the safety of a new suprachoroidal device, the Cypass micro-stent, for the surgical treatment of open-angle glaucoma (OAG) implanted in conjunction with cataract surgery. SETTING Multicenter clinical study. DESIGN Prospective interventional case series. METHODS This is an interim report of an ongoing safety study. Patients with OAG glaucoma (Shaffer grade 3 and 4) who were also candidates for cataract surgery in the affected eye had standard phacoemulsification followed by micro-stent implantation in the supraciliary space. Included were patients with uncontrolled (≥ 21 mm Hg, Cohort 1) or controlled (<21 mm Hg, Cohort 2) medicated intraocular pressure (IOP) at baseline. Glaucoma medications were discontinued at surgery and resumed at the discretion of each investigator. Measures included adverse events/complications and postoperative changes in IOP or medication. RESULTS The mean baseline medicated IOP was 21.1 mm Hg ± 5.91 (SD); the mean number of IOP-lowering medications was 2.1 ± 1.1 (N = 184). There were no major events such as retinal or choroidal detachment or endophthalmitis. The most common complications were transient early hypotony (13.8%) and transient IOP increase (10.5%). Uncontrolled patients (n = 57) had a 37% IOP reduction (P<.001), with more than a 50% reduction in glaucoma medications at 6 months (P<.001). Intraocular pressure-controlled patients (n = 41) had a 71.4% reduction in glaucoma medications (P<.001). CONCLUSION Initial clinical experience with the new micro-stent showed a low rate of surgical complications with concomitant decreases in IOP and/or glaucoma medications.
