Purpose. To determine the outcome of Molteno3 implantation as primary glaucoma surgery and to analyze the factors influencing the surgical outcome.Methods. This is a retrospective clinical study of 106 consecutive eyes (97 patients) with no previous glaucoma surgery. Surgical failure was defined as an IOP > 21 mmHg or less than a 20% reduction below baseline, or IOP ≤ 5 mmHg, on two consecutive visits after 3 months follow-up, or reoperation for glaucoma or loss of light perception.Results. At the end of the follow-up (mean, 35 months; range, 12–71 months), the mean postoperative IOP (14.2 ± 4.4 mmHg) was statistically significantly lower than the preoperative IOP (35.2 ± 9.7 mmHg) (P<0.001). Life-table success rates were 97%, 94%, and 91% after follow-up of 12, 24, and 36 months, respectively. Success rate for an IOP ≤ 18 mmHg was 77% at the last visit. Success was not influenced by previous cataract surgery, sex, age, laser trabeculoplasty (LTP), preoperative IOP, or number of antiglaucoma medications. Forty-seven eyes had 66 postoperative complications.Conclusions. The primary Molteno3 implant provided significant IOP lowering with minimal and manageable complications in uncontrolled glaucoma. Neither previous cataract surgery nor LTP had any detrimental effect on surgical success.

Aim: To check the short-term tonometric results of SLT in the treatment of primary glaucoma at the open angle and in charge of ocular hypertonias in Togolese people. Methods: A retrospective study was carried out in an ophthalmology center. The first 130 eyes of 72 patients benefited from the SLT laser procedure. The tonometric controls work object focus on follow-up at 1, 3, and 6 months post laser treatment. Results: 130 eyes of 72 patients were collected. The average age of the patients was 49.74 years (± 17.45) and the ages vary between 10 and 85 years. The average IOP of the laser before the laser (J0) was (24.99 ± 8.41) mm Hg. The mean IOP at the post-laser control at 1 month was (18.79 ± 3.73) mm Hg. The average IOP for the post-laser control at 3 months was (18.44 ± 3.81) mm Hg. The mean IOP at the post-laser control at 6 months was (18.13 ± 3.63) mm Hg. The percentage reduction in intraocular pressure compared to IOP was pretreated from 20.2% to 1 month; 22.1% at 3 months; and 23.3% at 6 months. In 1 month, 49.2% of the eyes we treated showed a reduction in IOP of less than 20% compared to IOP pretreatment. After 3 months and 6 months, it was 55.4% higher. Also, 52.3% have a PIO reduction percentage which is greater than or equal to 20% compared to pre-treatment IOP. Discussion: Selective laser trabeculoplasty, most especially, is interesting in ocular hypertonies. Treatment of over 180 ° allows one patient out of two to have a pressure reduction that is greater than or equal to 20%. Conclusion: The SLT presents a significant advantage for our glaucomatous patients.

Abstract Background To report the efficacy of ab externo canaloplasty by exclusively using only a nonabsorbable suture as a standalone operation or combined with phacoemulsification in terms of mean intraocular pressure (IOP), medication reduction, and intra- and postoperative complication rates as well as additional glaucoma surgery. Patients and Methods Forty-eight patients with primary open-angle glaucoma (POAG) and 50 eyes were divided into two groups according to the operation performed (Group A canaloplasty, n = 34 and Group B canaloplasty combined with phaco, n = 16), respectively. The success criteria were evaluated between three IOP ranges: a) IOP ≤ 16 mmHg, b) ≤ 18 mmHg, and c) ≤ 21 mmHg. Complete success was considered the percentage of eyes reaching these goals with no medication and qualified success with or without medication. Groups A and B were compared with the Kaplan-Meier test. Mean IOP and medication reduction as well as additional glaucoma surgery were also evaluated. The follow-up time was 6 months. Statistical importance was given at p < 0.05. Results Fail rate and intraoperative conversion of canaloplasty to other surgery (trabeculotomy due to extensive cheese-wiring) accounted for 12% (6 eyes), while a mandatory usage of the iTrack 250A microcatheter to successfully overcome intracanalicular bridging of the Schlemmʼs canal accounted for 20% (10 eyes). The most common early postoperative complications in both groups were hyphema, cheese wiring, and transient IOP rising. The mean IOP in Group A reduced from 23.67 ± 6.06 mmHg to 13.35 ± 4.23 mmHg and in Group B, it reduced from 23.55 ± 6.19 mmHg to 12.75 ± 1.5 mmHg at 6 months (p < 0.001). Group Aʼs absolute success rates accounted for a) 44%, b) 47.1%, and c) 52.9% in comparison to Group B [a) 50%, b) 50%, and c) 56.3%] at 6 months (p < 0.05). Qualified success with or without medication showed no statistical differences between the groups. The mean medication reduction was significantly lower (p < 0.001) in both groups (Group A from baseline 3.2 ± 1.23 to 0.95 ± 1.35 and Group B from 3.12 ± 0.88 to 1.12 ± 0.75 at 6 months, respectively). Five eyes (10%) required additional glaucoma surgery. Conclusions Ab externo canaloplasty by exclusively using only a nonabsorbable suture as a standalone operation or combined with phacoemulsification seems to lower the mean IOP and medication sufficiently. However, they pose a greater surgical challenge and intraoperative complication rate. Additional glaucoma surgery or medication following both procedures may be necessary to achieve an optimal target IOP.

Purpose. To report the outcomes of combined surgery using femtosecond laser-assisted cataract surgery (FLACS) and sutureless 27-gauge pars plana vitrectomy with intravitreal tamponade. Methods. This retrospective clinical study involved 23 eyes of 23 patients on whom combined vitreoretinal surgery was performed. Patients were initially given the femtosecond laser treatment that was performed after selection of capsulotomy and lens fragmentation patterns. The capsulotomy diameter was chosen as 4.9 mm in all patients. After the femtosecond laser, the sutureless phacovitrectomy procedure was performed. At the end of surgery, perfluoropropane or sterile air tamponade was applied. Results. The mean age of patients was 66.43 ± 7.61 (range, 54–83) years. Fifteen patients were females (65.2%). The mean follow-up was 16.09 ± 4.71 (range, 9–25) months. The most common surgical indication was epiretinal membrane (65.3%). The mean preoperative best-corrected visual acuity (BCVA) was 0.71 ± 0.44 (range, 1.7–0.3) logMAR, and the mean postoperative BCVA at 6 months was 0.16 ± 0.14 (range, 0.4–0) logMAR p<0.001. The mean target sphere refractive error was −0.24 ± 0.16 (range, −0.50–0.11) D, and the mean postoperative spherical equivalent refractive error was −0.14 ± 0.39 (range, −1.00–0.50) D at 6 months p=0.196. All intraocular lenses (IOLs) remained well centered in the capsular bag during surgery and follow-up. There was no iris capture, posterior synechiae, capsular opacification, or pseudophakic cystoid macular edema. The only complication related to femtosecond laser was two cases of subconjunctival haemorrhage related with suction. Conclusions. FLACS is a safe and effective technique providing the advantage of repeatable, precise capsulorhexis shape and size to achieve a well-centered and stable IOL postoperatively. These advantages can certainly improve the results of vitrectomy, especially in gas-filled eyes. FLACS and 27-gauge sutureless combined surgery may be a future trend in appropriate cases.

Abstract Purpose: To compare the efficacy of gonioscopy-assisted transluminal trabeculotomy combined with cataract surgery (PGATT) and trabeculectomy combined with cataract surgery (PTRAB) in open-angle glaucoma patients.Methods: A multicentered, retrospective, non-randomized study included 67 PGATT patients and 70 PTRAB patients. We compared preoperative intraocular pressure (IOP), best-corrected visual acuity (BCVA) compared with early and final IOP, medication numbers, and BCVA levels. Success was determined as IOP reduction >20% from baseline, IOP between 5-21 mmHg, preoperative IOP of higher than 21 mmHg with medication and postoperative IOP of less than 21 mmHg without medication for surgeries performed for intolerance to medication, postoperative IOP <21 mmHg as well as <18 mmHg separately without medications, and no need for further glaucoma surgery. Results: Preoperative IOP values were 28.61 ± 6.02 mmHg in PTRAB group and 23.99±8.00 mmHg in PGATT group (P<0.0001). Early postoperative IOP values were found lower in PTRAB group as 12.19 ± 3.41 mmHg and as 15.69 ± 4.67 mmHg in PGATT group (P<0.0001). Last follow-up IOP reading were lower in PGATT group (P=0.009). IOP difference values were found higher both in early and last postoperative periods in PTRAB group (respectively, P<0.0001, P=0.018). Success rates were found higher in both at lower than 21 and 18 mmHg levels in PGATT group (respectively, P=0.014, P=0.010).Conclusion: We found the PGATT combined procedure to be a well-tolerated, effective procedure that can lower IOP both early and late in the postoperative period with different rates of IOP success compared with the combined PTRAB procedure.

Introduction. To assess the safety and efficacy of selective laser trabeculoplasty (SLT) for ocular hypertension (OHT) induced by a dexamethasone (DEX) intravitreal implant. Materials and Methods. We performed a retrospective study of patients who underwent an SLT procedure for ocular hypertension induced by injection of a DEX intravitreal implant. Patients had, at least, one injection of the DEX-implant for symptomatic macular edema. SLT was delivered to 360° of the trabecular meshwork in two sessions. The primary outcome was a decrease in IOP, evaluated at one, three, and six months after the SLT procedure. Results. Twenty-six eyes of 22 patients were included. The mean intraocular pressure (IOP) measured after DEX-implant injection was 25.4 ± 5.4 mmHg, and the mean increase in IOP was 35.8 ± 14.6%. The mean follow-up after SLT was 18.3 ± 7.7 months. After SLT, the mean IOP dropped by 30.9% at one month (16.9 ± 4.5 mmHg, p = 0.01 ), 33.6% at three months (16.0 ± 2.7 mmHg, p < 0.01 ), and 34.9% at six months (15.6 ± 2.1 mmHg, p < 0.01 ). Each patient had a minimum follow-up of 6 months after SLT. Eight eyes (31%) received a second DEX-implant injection after the SLT procedure without experiencing an increase in the IOP above 21 mmHg or >20%. No glaucoma surgery was required during the follow-up. The mean number of medications (1.65 ± 1.36) was significantly reduced at one (1.19 ± 1.20, p = 0.04 ), three (0.96 ± 1.03, p < 0.01 ), and six months (0.77 ± 0.95, p < 0.01 ) after SLT. Conclusion. SLT is an effective and safe procedure to control OHT following DEX-implant intravitreal injection.

Purpose. To evaluate changes in flow density after the implantation of a trabecular microbypass stent (iStent) in combination with cataract surgery. Methods. A total of 48 eyes of 48 patients, who underwent either cataract surgery alone (cataract group) or cataract surgery with implantation of two iStent inject devices (iStent group), were prospectively included in this study. Intraocular pressure (IOP) and flow density data before and after surgery were extracted and analyzed. Results. In the iStent group, the mean IOP was 18.2 ± 3.3 mmHg prior to surgery and 13.2 ± 2.3 at follow-up, and this difference was statistically significant (p<0.001). The mean IOP in the cataract group also improved significantly after surgery (before: 17.1 ± 2.4; after: 15.1 ± 2.7 p=0.003). The flow density (whole en face) in the superficial and deep retinal OCT angiogram of the macula (superficial: p=0.002; deep: p=0.034) and in the ONH (p=0.011) improved significantly after surgery in the iStent group. The differences in the cataract group were not significant. Conclusions. Flow density of the macula and ONH, as measured by OCTA, improved significantly after cataract surgery with iStent. Noninvasive quantitative analyses of flow density provide a new parameter, which can help for the monitoring of therapy success after glaucoma surgery.

We compared surgical outcomes in patients with either primary open-angle glaucoma or exfoliation glaucoma after undergoing combined phacoemulsification with either a 120° or 180° incision during a Schlemm’s canal microhook ab interno trabeculotomy (μLOT-Phaco). This retrospective comparative case series examined 52 μLOT-Phaco eyes that underwent surgery between September 2017 and December 2020. Surgical qualified success was defined as an intraocular pressure (IOP) of ≤20 mmHg, ≥20% IOP reduction with IOP-lowering medications, and no additional glaucoma surgery. Success rates were evaluated by Kaplan-Meier survival analysis. The number of postoperative IOP-lowering medications and occurrence of complications were also assessed. Mean preoperative IOP in the 120° group was 16.9 ± 7.6 mmHg, which significantly decreased to 10.9 ± 2.7 mmHg (p < 0.01) and 11.1 ± 3.1 mmHg (p = 0.01) at 12 and 24 months, respectively. The mean number of preoperative IOP-lowering medications significantly decreased from 2.8 ± 1.4 to 1.4 ± 1.4 (p < 0.01) at 24 months. Mean preoperative IOP in the 180° group was 17.1 ± 7.0 mmHg, which significantly decreased to 12.1 ± 3.2 mmHg (p = 0.02) and 12.9 ± 1.4 mmHg (p = 0.01) at 12 and 24 months, respectively. The mean number of preoperative IOP-lowering medications significantly decreased from 2.9 ± 1.2 to 1.4 ± 1.5 (p < 0.01) at 24 months. The probability of qualified success at 24 months in the 120° and 180° groups was 50.4% and 54.6%, respectively (p = 0.58). There was no difference observed for hyphema formation or IOP spikes. Surgical outcomes were not significantly different between the 120° and 180° incisions in Schlemm’s canal.

Abstract Purpose To compare clinical success rates and reductions in intraocular pressure (IOP) and IOP-lowering medication use following suture trabeculotomy ab interno (S group) or microhook trabeculotomy (μ group). Methods This retrospective review collected data from S (n = 104, 122 eyes) and μ (n = 42, 47 eyes) groups who underwent treatment between June 1, 2016, and October 31, 2019, and had 12-month follow-up data including IOP, glaucoma medications, complications, and additional IOP-lowering procedures. The Kaplan–Meier survival analysis was used to evaluate treatment success rates defined as normal IOP (> 5 to ≤ 18 mm Hg), ≥ 20% reduction of IOP from baseline at two consecutive visits, and no further glaucoma surgery. Results Schlemm’s canal opening was longer in the S group than in the μ group (P < 0.0001). The Kaplan–Meier survival analysis of all eyes showed cumulative clinical success rates in S and µ groups were 71.1% and 61.7% (P = 0.230). The Kaplan–Meier survival analysis of eyes with preoperative IOP ≥ 21 mmHg showed cumulative clinical success rates in S and μ groups were 80.4% and 60.0% (P = 0.0192). There were no significant differences in postoperative IOP at 1, 3, and 6 months (S group, 14.9 ± 5.6, 14.6 ± 4.5, 14.6 ± 3.9 mmHg; μ group, 15.8 ± 5.9, 15.2 ± 4.4, 14.7 ± 3.7 mmHg; P = 0.364, 0.443, 0.823), but postoperative IOP was significantly lower in the S group at 12 months (S group, 14.1 ± 3.1 mmHg; μ group, 15.6 ± 4.1 mmHg; P = 0.0361). There were no significant differences in postoperative numbers of glaucoma medications at 1, 3, 6, and 12 months (S group, 1.8 ± 1.6, 1.8 ± 1.5, 2.0 ± 1.6, 1.8 ± 1.5; μ group, 2.0 ± 1.6, 2.0 ± 1.6, 2.1 ± 1.6, 2.2 ± 1.7; P = 0.699, 0.420, 0.737, 0.198). Conclusion S and µ group eyes achieved IOP reduction, but μ group eyes had lower clinical success rates among patients with high preoperative IOP at 12 months.

Intraoperative Parathyroid Hormone Assay

The role of the intraoperative parathyroid hormone (IOPTH) assay in patients with tertiary hyperparathyroidism (3HPT) is not well defined. To evaluate the utility of the IOPTH in 3HPT, we compared its use in 72 patients with primary hyperparathyroidism (1HPT) and 3HPT undergoing parathyroidectomy. Sixty-three patients with 1HPT and nine patients with 3HPT were identified. There were 30 men and 42 women (mean age, 58 years). The mean serum calcium and preoperative intact PTH levels in 1HPT were 11.1 mg/dL and 214 pg/mL compared with 11.2 mg/dL and 849 pg/mL in 3HPT (Ca, non significant; PTH, P < 0.05). Intraoperatively, a solitary abnormal gland was found in 62 of 72 (86%) patients. Seven patients with 3HPT had three- or four-gland hyperplasia. The two groups were compared to determine if a 10-minute postexcision IOPTH decline >50 per cent would have similar success rates. Seventy-one of 72 (98.6%) patients had a >50 per cent decline from the baseline IOPTH at the end of the operation. The average reduction from baseline was 85.3 per cent in 1HPT and 88.6 per cent in 3HPT (not significant). Average follow-up was 9.8 months for 1HPT and 11.1 months in 3HPT. Three of 63 patients (4.8%) with 1HPT and five of nine patients (55.6%) with 3HPT had inappropriate elevations in PTH ( P < 0.05). All patients with 3HPT were normocalcemic compared with 62 of 64 (97%) patients with 1HPT (not significant). The IOPTH assay can be used in 3HPT in an identical fashion with an equivalent rate of normocalcemia compared with its applications in 1HPT.

Abstract Precis: Phacoemulsification combined with MicroPulse transscleral cyclophotocoagulation appears to provide significantly greater long-term IOP reduction than phacoemulsification combined with endoscopic cyclophotocoagulation without compromising safety.Purpose: To compare the effectiveness and safety of phacoemulsification combined with endoscopic cyclophotocoagulation (phaco/ECP), phacoemulsification combined with MicroPulse transscleral cyclophotocoagulation (phaco/MP-TSCPC), and phacoemulsification alone (phaco) in the treatment of coexisting cataract and glaucoma. Methods: Retrospective cohort study of consecutive cases at Massachusetts Eye & Ear. The main outcome measures were the cumulative probabilities of failure between the phaco/ECP group, phaco/MP-TSCPC group, and the phaco alone group with failure defined as reaching NLP vision at any point postoperatively or the inability to maintain ≥20% IOP reduction from baseline with IOP between 5-18 mmHg. Additional outcome measures included changes in average IOP, number of glaucoma medications, and complication rates. Results: 64 eyes from 64 patients (25 phaco/ ECP, 20 phaco/ MPTSCPC, 19 phaco alone) were included in this study. The groups did not differ in age (mean 71.04 ± 6.7 years) or length of follow-up time. Primary open-angle glaucoma was the most common type of glaucoma in the phaco alone (42%) and phaco/ECP (48%) groups while mixed-mechanism glaucoma was the most common type in the phaco/MP-TSCPC group (40%). The mean IOP reductions at 1 year were 3.07 ± 5.3 mmHg from a baseline of 15.78 ± 4.7 in the phaco/ECP group, 6.0 ± 4.3 mmHg from a baseline of 18.37 ± 4.6 in the phaco/MP-TSCPC group and 1.0 ± 1.6 from a baseline of 14.30 ± 4.2 mmHg in the phaco alone group. Surgical failure was less likely in eyes in the phaco/MP-TSCPC and phaco/ECP groups compared to phaco alone based on the Kaplan-Meier survival criteria, with failure defined as the inability to maintain an IOP reduction of 20% or more with IOP between 5-18 mm Hg long term. There were no differences in complications among the three groups. Conclusions: Phaco/MP-TSCPC appears to provide for greater long-term IOP control than phaco alone and phaco/ECP. All three procedures had similar safety profiles.
