Graefes Arch Clin Exp Ophthalmol 2024; 262:927-935. [PMID: 37843563 DOI: 10.1007/s00417-023-06265-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2023] [Revised: 09/24/2023] [Accepted: 09/28/2023] [Indexed: 10/17/2023] Open
Abstract
PURPOSE Intraocular pressure (IOP) spikes (IOP > 30 mmHg or > 10 mmHg above baseline IOP) are a common and worrisome complication of gonioscopy-assisted transluminal trabeculotomy (GATT). The purpose of this study is to identify risk factors for IOP spikes and to describe their characteristics, management, and clinical course in a large cohort of patients. METHODS A retrospective, single-center study which included 217 consecutive eyes of patients that underwent GATT between December 2019 and April 2022 with follow-up of at least 90 days. RESULTS IOP spikes occurred in 52 of 217 (24%) eyes. Spikes occurred in 15.5% of patients in whom pre-operative IOP-lowering medications were continued after surgery (90 eyes), and in 29.9% in whom IOP-lowering medications were stopped after surgery (127 eyes). Spikes were diagnosed at a mean of 7.7 ± 6.5 days after surgery. All IOP spikes occurred within the first month of surgery. The mean duration of a spike was 4.9 ± 5.4 days. Management of IOP spikes included adding a mean of 3.13 ± 1.7 groups of glaucoma medications. Thirty-seven (72.5%) eyes were treated with oral carbonic anhydrase inhibitor, 11 (21.6%) were treated with IV mannitol, and anterior chamber paracentesis was performed in 16 (31.4%). Six (11.8%) eyes underwent additional glaucoma surgery to control IOP. Patients that continued their pre-operative IOP-lowering medications after surgery were 2.3 times less likely to develop a spike as compared to patients who discontinued their medications (P = 0.016). Spikes were found to be a risk factor for failure of GATT. CONCLUSIONS IOP spikes are a common occurrence after GATT. They most commonly appear during the first two post-operative weeks and usually resolve with topical and systemic IOP-lowering treatment. The continuation of IOP-lowering medications after GATT is recommended to lower the risk of IOP spikes.

Lai J, Qiao Y, Tan C, Chen J. Outcomes of gonioscopy-assisted transluminal trabeculotomy in primary congenital glaucoma treatment: a retrospective study. BMC Ophthalmol 2024; 24:88. [PMID: 38408950 PMCID: PMC10898054 DOI: 10.1186/s12886-024-03351-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2023] [Accepted: 02/15/2024] [Indexed: 02/28/2024] Open
Abstract
BACKGROUND This retrospective study aimed to evaluate the efficacy and safety of gonioscopy-assisted transluminal trabeculotomy (GATT) in Chinese patients with primary congenital glaucoma (PCG) and identify factors influencing surgical success. METHODS Fourteen patients (24 eyes) diagnosed with PCG who underwent gonioscopy-assisted transluminal trabeculotomy were recruited, and data on intraocular pressure (IOP), antiglaucoma medication, surgery-related complications, and additional treatments were collected during preoperative and postoperative visits. Surgical success was defined as IOP ≤ 21 mmHg and a reduction of > 30% from baseline, with (partial success) or without (complete success) antiglaucoma medication. RESULTS Mean preoperative IOP was 30.41 ± 6.09 mmHg. At the final visit, mean IOP reduction was 16.1 ± 9.1 mmHg (52%), and 19 of 24 eyes were topical medication-free. IOP was significantly decreased at each postoperative visit compared with baseline (P < 0.05 for all time points). Cumulative proportions of complete and partial success were 79.2% and 95.8%, respectively, at three years postsurgery. Patients without prior antiglaucoma procedures, without postoperative IOP spikes, and those undergoing complete trabeculotomy exhibited improved surgical prognosis. No permanent vision-threatening complications occurred in the 24 eyes by the end of the respective follow-ups. CONCLUSION Gonioscopy-assisted transluminal trabeculotomy emerged as a safe and effective procedure for PCG treatment, characterized by outstanding IOP reduction efficacy and high surgical success rates.

Abstract
Gonioscopy-assisted transluminal trabeculotomy (GATT) has been used as a safe and effective procedure in the treatment of open angle glaucoma. In the present report, we demonstrated successful IOP control in two uveitic glaucoma cases secondary to juvenile idiopathic arthritis (JIA) following 360° GATT. Case 1 was a 7-year-old pseudophakic male with a preoperative IOP of 38 mmHg; his IOP stabilized at 17 mmHg with two topical antiglaucoma medications over 18 months. Case 2 was a 8-year-old aphakic male with a preoperative IOP of 42 mmHg; his IOP decreased to 12 mmHg over 15 months. We observed postoperative IOP spike in case 1 which was successfully controlled conservatively. Peripheral anterior synechia formation also occured in both cases during follow-up. One should be vigilant for possible complications after GATT in such cases. As glaucoma surgery success can have a tendency to decline with time in pediatric cases with uveitis-associated glaucoma, we believe that further evidence is still required to shed more light about the benefits of GATT technique in complex cases of pediatric secondary glaucoma subtypes like JIAU-induced glaucoma.

Abstract
PURPOSE To report the outcomes of a 120-degree goniotomy (GT) with or without secondary intraocular lens (IOL) implantation in glaucoma following cataract surgery (GFCS). DESIGN Prospective, observational study. METHODS Pediatric patients with GFCS who underwent standalone 120-degree GT or 120-degree GT combined with secondary IOL implantation (GT+IOL) from March 2022 to August 2022 at the Zhongshan Ophthalmic Center were recruited. Primary outcomes were intraocular pressure (IOP) and the number of ocular hypotensive medications. A secondary outcome was the surgical success rate. Success was defined as a postoperative IOP within the range of 5-21 mm Hg. Complete and qualified successes were defined, as the above, without and with ocular hypotensive medications, respectively. RESULTS Thirty-two eyes of 22 patients were included. The mean age at the time of GT was 68.5 ± 29.3 months. The mean follow-up duration was 12.2 ± 2.3 months (9-15 mo). Mean IOP decreased from 30.9 ± 4.8 mm Hg on 2 (interquartile range = 1) medications at baseline to 15.8 ± 3.6 mm Hg on 0 (interquartile range = 1.5) medication at the latest visit in all eyes. The overall complete and qualified success rates were 68.8% and 90.6%, respectively. There were no significant differences in IOP, number of medications, and complete and qualified success rates between the standalone GT and GT+IOL groups at the latest follow-up at 9 months postoperatively. CONCLUSIONS To reduce the need for additional surgery, 120-degree GT was a safe and effective surgical treatment for GFCS in children, which could be combined with secondary IOL implantation in aphakic eyes with GFCS.

Abstract
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.

Abstract
PURPOSE To quantitatively assess the development of peripheral anterior synechia (PAS) formation rate and PAS locations on gonioscopic examination following gonioscopy-assisted transluminal trabeculotomy (GATT) surgery and investigate the surgical outcomes. METHODS A total of 35 eyes from 31 patients with open angle glaucoma who underwent GATT or combined GATT and phacoemulsification surgery were analyzed. Presence of PAS was assessed on gonioscopy in nasal, temporal, superior and inferior quadrants at months 1, 3 and 6 following surgery. Surgical outcomes were also noted. RESULTS Frequencies of PAS formation were 38.3%, 25.3%, 17.0% and 19.1% at postoperative 1 month, 34.0%, 26.4%, 17% and 22.6% at postoperative 3 months and 32.3%, 25.8%, 16.1% and 25.8% at postoperative 6 months, in nasal, temporal, superior and inferior quadrants, respectively. The highest amount of PAS involvement was 3 clock hours in the study which was identified only in nasal and inferior quadrants. Frequency of PAS formation did not significantly differ between nasal, temporal, superior and inferior quadrants at all time points (p > 0.05). No significant differences of mean IOP levels were observed between patients who developed PAS and who did not develop PAS at postoperative 1 month (p = 0.72), 3 months (p = 0.21) and 6 months (p = 0.59). The mean IOP and mean number of antiglaucoma medications decreased from 31.5 ± 7.2 mmHg and 3.6 ± 0.6 at baseline to 13.8 ± 3.1 mmHg and 1.6 ± 1.3 at postoperative 6 months, respectively (p < 0.001, for both). Cumulative success rate (95% confidence interval) was 74.3% (69.9-78.6%) at the end of the study. Mild to moderate degrees of hyphema occurred in all cases postoperatively. CONCLUSION Although PAS formation was observed to be relatively higher in nasal quadrant, PAS frequency was not statistically different between the angle quadrants.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:2759. [PMID: 36768125 PMCID: PMC9914959 DOI: 10.3390/ijerph20032759] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/04/2022] [Revised: 01/30/2023] [Accepted: 02/01/2023] [Indexed: 06/18/2023]
Abstract
AIM The aim of the study was to retrospectively evaluate the efficacy and safety of GATT during a 6-month observation period. MATERIAL AND METHODS The studied group consisted of 69 open-angle glaucoma patients treated with GATT as the only procedure or in combination with cataract surgery. Patients were assessed 1 day, 10 days, 1 month, 3 months, and 6 months after the surgery via standard ophthalmic examination including VF, IOP, and BCVA. The number of medications taken daily and possible complications were checked. Two criteria of success were established (S1: IOP decrease by 30% and S2: IOP lower than 18 mm Hg). RESULTS Before the surgery, the mean IOP was 26.94 mmHg and significantly decreased after GATT to 15.59 mmHg at 6M. BCVA did not significantly differ between the visits. The mean MD did not change significantly within the 6-month observation period (-8.20 dB vs. -8.16 dB, p = 0.9824), similar to the mean VFI (64.31% vs. 63.05%, p = 0.8571). A 30% IOP decrease at 6M visit was obtained in 95.6% of patients, and 37.7% needed medications to stabilize IOP. An IOP lower than 18 mmHg at 6M was obtained in 91.3% of studied patients after the GATT procedure, and in 58.0% without additional medications. The mean number of medications received daily decreased significantly at 6M compared to preoperative results (2.59 at inclusion vs. 0.76 at 6M, p = 0.0004). The most frequent complication after surgery was hyphema, which resolved spontaneously within 10 days. CONCLUSION The 6-month observation showed that GATT is a minimally invasive glaucoma-surgery technique that enables an effective and safe IOP decrease.

Abstract
Glaucoma following cataract surgery (GFCS) remains a serious postoperative complication of pediatric cataract surgery. Various risk factors, including age at lensectomy, intraocular lens implantation, posterior capsule status, associated ocular/systemic anomaly, additional intraocular surgery, and a family history of congenital cataract and GFCS, have been reported. However, the optimal surgical approach remains unclear. This review evaluates the diagnostic criteria, classification, risk factors, mechanism, and surgical management, especially the efficacy of minimally invasive glaucoma surgery, in GFCS, and aims to propose an optimal clinical management strategy for GFCS. The results of our review indicate that ab interno trabeculotomy (goniotomy) may be the most appropriate first-line treatment for GFCS.
