Prcis: Gonioscopy-assisted transluminal trabeculotomy (GATT) provided effective intraocular pressure (IOP) control in primary congenital glaucoma (PCG). Also, approximately two third of patients did not need antiglaucoma medication at an average follow-up of 1 year after surgery., Purpose: The purpose of this study was to assess the safety and efficacy of GATT surgery in eyes with PCG., Materials and Methods: This study is a retrospective review of patients who underwent GATT surgery for PCG. Outcome measures were changes in IOP and number of medications at all time points (1, 3, 6, 9, 12, 18, 24, and 36 mo after surgery), and success rates. Success was defined as IOP<21 mm Hg with at least a 30% reduction from the baseline, complete if without medications, or qualified if with or without medications. Cumulative success probabilities were analyzed using the Kaplan-Meier survival analyses., Results: Twenty-two eyes of 14 patients diagnosed with PCG were enrolled in this study. The mean IOP reduction was 13.1 mm Hg (57.7%) with a mean decrease of 2 glaucoma medications at the final follow-up. All mean IOP readings during postoperative follow-up were significantly lower than baseline ( P <0.05 for all). Cumulative probability of qualified success was 95.5% and the cumulative probability of complete success was 66.7%., Conclusion: GATT was safe and successfully lowered IOP in patients with PCG with the advantage of avoiding conjunctival and scleral incisions., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Prcis: This study demonstrates that a baseline corneal diameter >12.25, initial age <4 months at diagnosis, higher baseline IOP than 24 mm Hg, bilaterality, or inability to perform circumferential trabeculotomy, increases the risk of surgical failure of trabeculotomy in patients with primary congenital glaucoma (PCG)., Purpose: The aim of this study was to identify clinical predictive factors for surgical failure and to evaluate potential prognostic factors affecting surgical success in patients with PCG who underwent trabeculotomy., Patients and Methods: The medical charts of 123 eyes of 75 patients who underwent trabeculotomy surgery for the treatment of PCG were retrospectively reviewed. At baseline and each visit, intraocular pressure (IOP), corneal diameter, cup to disc ratio, axial length, number of medications, and need for further glaucoma surgery were noted. Surgical success was defined as an IOP ≤18 mm Hg and 20% IOP reduction from baseline with (qualified) or without (complete) medication and without any further IOP-lowering surgery., Results: The mean age at surgery was 4.2±6.6 months and the mean follow-up time was 60.0±37.6 months. The receiver operating characteristic curve showed 4 following best cutoff values to predict surgical failure: the first for age at surgery was 4.5 months; the second baseline IOP was 24.0 mm Hg; the third for baseline cup to disc ratio was 0.4; and the fourth for baseline corneal diameter was 12.25 mm. Multivariate logistic regression analysis revealed that baseline IOP more than 24 mm Hg increased the risk of surgical failure by 2 times, baseline mean corneal diameter >12.25 mm did by 4.2 times, younger age than 4 months did by 2.5 times, bilaterality did by 1.5 times., Conclusions: A higher baseline IOP, younger age, larger corneal diameter, and bilaterality were identified as risk factors for trabeculotomy failure in congenital glaucoma. The presence of one or more of these should be considered in the decision-making process when considering surgical options to manage glaucoma in these patients., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Prcis: Gonioscopy-assisted transluminal trabeculotomy (GATT) provides greater intraocular pressure (IOP) reduction in pseudoexfoliative glaucoma (PXG) than in primary open angle glaucoma (POAG) in the first year of surgery; however, the difference between groups equalizes in the long term., Purpose: To compare outcomes of GATT in eyes with POAG and PXG., Methods: Single-center, retrospective, comparative case-series. A total of 202 eyes (91 eyes of POAG; 111 eyes of PXG) were included. GATT was performed as a standalone procedure or in combination with cataract extraction. Outcome measures were change in IOP and number of medications at all time points (1, 3, 6, 9, 12, 18, 24, and 36 mo after surgery), success rate (IOP reduction ≥20% from baseline or IOP between 6 and 21 mmHg, without further glaucoma surgery), and complication rate. Cumulative success probabilities were compared using Kaplan-Meier survival analyses., Results: The mean IOP decreased by 8.8 mmHg (34.4%) in the POAG group with a mean decrease of 2 glaucoma medications at final visit. In the PXG group, the mean IOP decreased by 12.8 mm Hg (44.6%) on 2.3 fewer medications. Mean IOP reduction was significantly higher in PXG than POAG at all time points up to 2-year visit ( P <0.05 for all), after which the difference was not significant. Cumulative success probability during the first year was significantly higher in PXG (97.6%) than in POAG (86.8%) ( P =0.01); no significant difference was found at 2-year ( P =0.07) and 3-year visits ( P =0.24)., Conclusion: GATT was safe and effectively reduced the IOP and medication burden in patients with POAG and PXG. In the first year after GATT, a significantly higher success rate was noted in PXG compared with POAG; however, in subsequent years, the success rate was similar at ~75%., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Prcis: The present study demonstrates that surgical success rates of gonioscopy-assisted transluminal trabeculotomy (GATT) with a target intraocular pressure (IOP)≤21 mm Hg are 93.3% (for qualified success) and 26.7% (for complete success) in vitrectomized patients exhibiting secondary open-angle glaucoma (SOAG) after silicone oil (SO) removal, for an average follow-up of 37.5 months., Purpose: To report the long-term outcomes of GATT in vitrectomized patients exhibiting SOAG after SO removal., Setting: Retrospective case-series study., Patient Population: This retrospective case-series study enrolled vitrectomized patients who underwent uneventful GATT surgery between May 2014 and May 2019 at Gazi University Hospital for the treatment of medically uncontrolled SOAG after SO removal., Main Outcome Measures: At baseline and at each postoperative visit, a detailed ophthalmic examination consisting of slit-lamp biomicroscopy, indirect ophthalmoscopy, macular optical coherence tomography, and Goldmann applanation tonometry was performed in all patients. Baseline demographic and clinical characteristics, duration between pars plana vitrectomy and SO removal, duration between SO removal and onset of SOAG, follow-up time, need for antiglaucoma medication, visual acuity, and IOP measurements were noted. Surgical success was defined as an IOP≤21 and ≥6 mm Hg with (qualified success) and without (complete success) IOP-lowering medication., Results: A total of 15 patients had a history of pars plana vitrectomy with 1000 centistoke SO tamponade before the GATT surgery. GATT was performed in all patients with SOAG after SO removal. The mean age and follow-up of the patients were 53.6±11.8 years (range, 34 to 72 y) and 37.5±15.1 months (range, 12 to 61 mo), respectively. The average duration of SO tamponade in the vitreous cavity was 7.5±1.6 months (range, 5 to 10 mo). The average duration between the SO removal and the development of SOAG was 14.1±13.2 months (range, 2 to 46 mo). The mean IOP decreased from 31.0±4.1 mm Hg at baseline to 15.6±4.6 mm Hg at final visit. The mean final logMAR BCVA was 0.92±0.58 (range, 2 to 0.045). Qualified surgical success was achieved in 14 (93.3%) patients, whereas complete success was achieved in only 4 (26.7%) patients (P<0.001)., Conclusions: GATT seems to be safe and successful procedure for controlling IOP in patients exhibiting SOAG after SO removal. However, most patients may require antiglaucoma medication during the follow-up, particularly within the first 2 postoperative years., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2020 Wolters Kluwer Health, Inc.

PRéCIS:: Intravitreal anti-vascular endothelial growth factor therapy resulted in sustained elevation of intraocular pressure (IOP) in 18.6% of patients with coexisting age-related macular degeneration and pseudoexfoliation (PXF) syndrome. The development of sustained elevation of IOP after ~19 injections reflected the cumulative effect of anti-vascular endothelial growth factor injections on IOP., Purpose: The purpose of this study was to compare the long-term effect of intravitreal ranibizumab (IVR) and intravitreal bevacizumab (IVB) therapies on IOP in patients with and without PXF syndrome., Design: This was a retrospective comparative study., Patients and Methods: Data from 412 eyes of 206 patients diagnosed with unilateral neovascular age-related macular degeneration, treated with IVR or IVB, and followed-up for at least 6 months, were retrospectively reviewed. Seventy treated and 70 untreated fellow eyes of 70 patients with bilateral PXF syndrome, and 136 treated and 136 untreated fellow eyes of 136 patients without PXF syndrome were included in this study. Demographic information, clinical findings, total number of IVR and IVB injections, and IOP values at each visit were recorded. Sustained elevation of IOP (SE-IOP) was defined as either an IOP >21 mm Hg or a ≥5 mm Hg increase in IOP from baseline for at least 2 consecutive visits. Baseline and final IOP values in each group were compared using the paired sample t test, and IOP changes in the groups were compared using split-plot analysis of variance. Multivariate logistic regression analysis was used to evaluate the influence of variables on the development of SE-IOP., Results: The mean (±SD) age of the patients was 77.53±3.78 years (range, 70 to 83 y), and the mean follow-up was 28.50±16.51 months (range, 6 to 58 mo). The mean number of injections was 15.56±8.01 (range, 5 to 36). The mean baseline and final IOP in treated eyes were 14.82±3.08 and 16.50±3.11 mm Hg, respectively (P<0.001). A higher incidence of SE-IOP and higher final IOP values were observed in PXF-positive eyes receiving IVB compared with the other groups. Seven of the patients required antiglaucomatous treatment. Multivariate logistic regression analysis revealed an increased odds ratio (4.90; P=0.016) of SE-IOP in PXF-positive eyes compared with PXF-negative eyes., Conclusion: IVB therapy may cause greater increases in IOP in patients with PXF syndrome. The co-accumulation of PXF material and bevacizumab particles on the trabecular meshwork should be further investigated.

PRéCIS:: The present study demonstrates that the surgical success rate of circumferential trabeculotomy is 64.7% according to target intraocular pressure (IOP) ≤21 mm Hg and ≥30% reduction from baseline in patients with neonatal-onset primary congenital glaucoma (PCG), with an average follow-up of 35.1 months., Purpose: The aim of the study was to evaluate the surgical success rate and applicability of circumferential trabeculotomy compared with converted traditional trabeculotomy in patients with neonatal-onset PCG in Turkey., Patients and Methods: A retrospective study enrolled 42 eyes of 42 patients with an average age of 34.0±6.7 (14 to 59) days at the time of the surgery, who underwent 5/0 prolene suture-assisted circumferential trabeculotomy or rigid probe-assisted traditional trabeculotomy for the treatment of neonatal-onset PCG. IOP at baseline, 1st, 2nd, 3rd, 6th, 9th, 12th, 24th, and 36th months of follow-up, need of glaucoma eye drop, need of further glaucoma surgery, cup to disc ratio, axial length, corneal diameters, and presence of corneal clouding were recorded. Surgical success was defined as IOP <21 mm Hg and ≥30% reduction from baseline without any further glaucoma surgery., Results: Seventeen eyes underwent circumferential trabeculotomy and 25 eyes with a failure in completing circumferential trabeculotomy underwent traditional trabeculotomy. The applicability rate of circumferential trabeculotomy was 40.4%. The mean preoperative IOP value was 33.2±7.6 mm Hg. The average follow-up time was 35.1±21.7 (12 to 95) months. Surgical success rates of circumferential trabeculotomy at the first, second, and third year of follow-up were 70.6%, 64.7%, and 64.7%, respectively. Surgical success rates of traditional trabeculotomy at the first, second, and third year of follow-up were 60%, 48%, and 44%, respectively., Conclusions: Circumferential trabeculotomy seems to be a safer and more successful procedure than traditional trabeculotomy for the treatment of neonatal-onset PCG. Unlike the traditional procedure, the IOP-lowering effect of circumferential trabeculotomy could be maintained up to ~36 months.

Purpose: The purpose of this study was to report 2 cases experiencing a transient decrease in their vision due to the development of acute myopia after an uneventful prolene gonioscopy-assisted transluminal trabeculotomy (GATT) surgery., Methods: A 52-year-old woman with primary open-angle glaucoma and an 8-year-old boy with juvenile glaucoma underwent uneventful GATT surgery., Results: On the postoperative first day, both patients had mild shallow anterior chamber and intraocular pressures measured as 19 and 16 mm Hg, respectively. Both patients had myopia measured as -4.5 and -6.0 D, respectively. Fundus examination was unremarkable in the first patient, whereas it showed bilateral optic disc cupping and retinal nerve fiber layer atrophy in the second patient. In the first patient, supraciliary effusion was detected by using ultrasound biomicroscopy. Ultrasound biomicroscopy could not be performed in the second patient, but ocular ultrasonography revealed a thin layer of suprachoroidal fluid. Myopia was completely regressed, and visual acuity increased within 1 week of the follow-up in both patients. At the sixth month of the follow-up, intraocular pressures in both patients were under control without any antiglaucoma medications., Conclusion: Transient decrease in vision after the GATT surgery might occur secondary to supraciliary effusion leading to acute, transient myopia.

PRéCIS:: The present study demonstrates that surgical success rate of gonioscopy-assisted transluminal trabeculotomy (GATT) is 83.7% according to target intraocular pressure (IOP) ≤21 mm Hg and ≥20% reduction from baseline in patients with moderate to advanced glaucoma, with an average follow-up of 19.4 months., Purpose: The aim of the study was to assess the outcomes of GATT in eyes with moderate to advanced open-angle glaucoma., Patients and Methods: A retrospective study included 104 eyes of 104 patients, with a mean age of 58.9±18.5 (15 to 87) years, who underwent GATT using the 6/0 prolene suture to treat open-angle glaucoma. The GATT procedure was carried out alone or in combination with phacoemulsification. IOP at baseline, third, sixth, ninth, 12th, and 18th months of follow-up; need of antiglaucoma medication; need of further glaucoma surgery; cup/disc ratio; and best-corrected visual acuity (BCVA) were recorded. Patients with prior incisional glaucoma surgery were excluded. Surgical success was determined for both IOP <21 and <18 mm Hg and also ≥20% reduction from baseline without further glaucoma surgery., Results: A total of 65 patients with primary open-angle glaucoma (POAG) and 39 patients with secondary open-angle glaucoma (SOAG), including pseudoexfoliative, pigmentary, uveitic, and steroid-induced glaucoma underwent GATT. Preoperative mean IOP was 25.0±7.3 mm Hg. Preoperative average number of antiglaucoma medications was 3.4±0.6. The average follow-up time was 19.4±8.1 (6 to 37) months. Preoperative average BCVA was 0.51±0.24, and cup/disc ratio was 0.85±0.14. Surgical success was achieved in 87 of 104 (83.7%). Seven patients had medically uncontrolled glaucoma after GATT surgery, and they underwent further surgery. Patients with POAG had a higher percentage of IOP reduction than patients with SOAG at 18th month of follow-up (40.1% vs. 27.6%). Need for medication at final visit was similar between POAG and SOAG., Conclusion: GATT procedure is a safe and successful option for the treatment of moderate to advanced open-angle glaucoma. Surgical success could be maintained up to ∼18 months.

Purpose: The main purpose of this study was to report a case of panscleritis after gonioscopy-assisted transluminal trabeculotomy (GATT)., Methods: We describe the case of a 33-year-old man with a history of unilateral anterior uveitis and glaucoma, who developed panscleritis after GATT surgery., Results: Uneventful GATT surgery was performed in a glaucomatous left eye. On the second postoperative day, the patient developed tenderness on palpation of the eye. Ophthalmic examination revealed significant diffuse hyperemia, elongated and tortuous upper bulbar conjunctival/scleral vessels, and exudative retinal detachment at the superior nasal quadrant, with diffuse scleral thickening. The patient was diagnosed as having panscleritis, which was attributed to the GATT surgery. Although the scleritis resolved completely with intravenous and oral methylprednisolone treatment, localized retinal detachment persisted., Conclusions: Surgery-induced posterior scleritis may occur following minimally invasive glaucoma surgeries such as GATT. Control of uveitis for at least 3 months before surgery is indicated in patients with uveitis if GATT surgery is planned.

Purpose: To evaluate the effect of erythropoietin (EPO) treatment on retinal nerve fiber layer (RNFL) parameters in patients with chronic renal failure (CRF) undergoing peritoneal dialysis (PD)., Methods: Fifty-eight eyes of 29 patients with CRF undergoing PD were evaluated. Fifteen patients have been treated with EPO (group 1), 14 patients without EPO treatment (group 2), and 30 eyes of 15 age-matched normal control subjects were assessed in group 3. A complete ophthalmologic examination and RNFL measurements were performed for each patient after PD. Anemia parameters were also measured. RNFL thickness protocol was used to acquire circular scans of 3.4 mm in diameter around optic nerve. RNFL thicknesses were evaluated in 4 quadrants. Only the left eyes were recruited for statistical analysis. The mean and quadrantal RNFL thickness values in group 1 were compared with those of groups 2 and 3., Results: The mean RNFL thickness values in patients undergoing PD were statistically lower than the control group at superior, inferior, nasal, and temporal quadrant, respectively (P=0.03, 0.04, 0.04, and 0.03). Differences between the RNFL thickness values in group 1 and group 2 were statistically significant only in the temporal quadrant (P=0.02)., Conclusions: In patients with CRF undergoing PD, RNFL thickness parameters were found to be significantly reduced. The effect of EPO on RNFL parameters was statistically significant only in the temporal quadrant.

Purpose: The purpose of the study was to report a patient with Seckel syndrome associated with high intraocular pressures despite intensive antiglaucoma treatment., Methods: Case report., Results: High intraocular pressure readings in both eyes measured with the Goldman applanation tonometer, bilateral pigmentary retinopathy and total cupping of optic discs were found. The patient underwent bilateral trabeculectomy surgery as he had medically uncontrolled glaucoma., Conclusions: Childhood glaucoma may be associated with Seckel syndrome.
