AimTo analyse long-term visual outcomes across different subtypes of primary congenital glaucoma (PCG).MethodsPatients with PCG with a minimum of 5-year follow-up post surgery were included in the study. Snellen visual acuity recordings taken at their last follow-up were analysed. We evaluated the results using Kaplan-Meier curves to predict the probability of maintaining good vision (as defined by a visual acuity of 6/18 or better) in our patients after 30-year follow-up. The results were also analysed to determine whether there were any differences in the long-term visual acuities with time between the neonatal and infantile PCG. We also analysed the reasons for poor visual outcomes.ResultsWe assessed a cohort of 140 patients with PCG (235 eyes) with an average follow-up of 127±62.8 months (range 60–400 months). Overall, the proportion of eyes with good visual acuity was 89 (37.9%), those with fair visual acuity between 6/60 and 6/18 was 41 (17.4%), and those with poor visual acuity (≤6/60) was 105 (44.7%). We found a significant difference (p=0.047) between neonatal and infantile patients with PCG whereby the neonatal cohort fared worse off in terms of visual morbidity. On Kaplan-Meier analysis, the cumulative probability of survival of a visual acuity of 6/18 or better was more among the infantile PCG in comparison to the neonatal PCG (p=0.039) eyes, and more among the bilateral than the unilateral affected eyes (p=0.029). Amblyopia was the most important cause for poor visual acuity as shown on a Cox proportional-hazards regression model .ConclusionsLong-term visual outcomes of infantile are better than neonatal PCG. Eyes with unilateral have worse visual outcomes compared with those with bilateral PCG because of the development of dense amblyopia.

Aim To determine the long-term outcomes of a cohort of complex patients with primary congenital glaucoma, aniridia and anterior segment dysgenesis. Methods Retrospective consecutive series between 1990–2021 in two UK tertiary centres: Guy's and St Thomas’ NHS Foundation Trust and King's College Hospital NHS Foundation Trust. We recorded the number and types of surgical and laser treatments along with preoperative and postoperative data, including intraocular pressures (IOP) and anti-glaucoma medications. Results A total of 41 eyes of 21 patients were included. Primary diagnoses were primary congenital glaucoma in 16 eyes (39.0%), aniridia in 14 eyes (34.2%), and anterior segment dysgenesis in 8 eyes (19.5%). Sixteen eyes (39.0%) had one or more glaucoma surgery or laser procedures for advanced glaucoma, and the long-term follow-up was 12.8 ± 3.6 years. There was a significant decrease in postoperative IOP (mmHg) at 3 months (16.5 ± 1.6; p = 0.0067), 6 months (18.7 ± 2.1; p = 0.0386), 12 months (18.6 ± 1.7; p = 0.0229), 3 years (14.7 ± 1.2; p = 0.0126), 5 years (15.5 ± 1.8; p = 0.0330) and 10 years (15.4 ± 2.3; p = 0.7780), compared to preoperatively (24.1 ± 2.6). Surgical success (complete and qualified) was 62.5%, 50.0%, 43.8%, 46.2%, 45.5% and 28.6% at 3 months, 6 months, 12 months, 3 years, 5 years and 10 years, respectively. There was no significant change in the number of anti-glaucoma drugs postoperatively ( p > 0.05). Four eyes (25.0%) had postoperative complications (hyphaema, hypotony) that resolved after conservative management. Conclusions Surgical management of these complex eyes with advanced glaucoma is challenging. Overall, the cohort had good surgical outcomes with a significant decrease in IOP by 36.1% after long-term follow-up.

Purpose To assess the long-term results of viscotrabeculotomy in infants with primary congenital glaucoma and to compare its outcome with conventional trabeculotomy. Patients and methods A prospective randomized comparative study included infants with primary congenital glaucoma younger than 2 years. Patients were divided into two groups: viscotrabeculotomy group and conventional trabeculotomy group. Preoperative and postoperative intraocular pressures, corneal diameter, intraoperative and postoperative complications, and success rates were compared between two groups. All the patients were followed up for 5 years. Results The study included 154 eyes of 92 infants distributed randomly among the two groups; 78 and 76 eyes in viscotrabeculotomy and conventional trabeculotomy groups, respectively. In both groups, there was a statistically significant intraocular pressure reduction at all time points of the follow-up periods compared to the preoperative values (p < 0.0001). At 5 years, viscotrabeculotomy group showed significant reduction of the mean postoperative intraocular pressure (49.47%) than conventional trabeculotomy group (48.64%) (p < 0.0001). Intraocular pressure was statistically lower in viscotrabeculotomy starting from 12th month and till the end of the follow-up. At 5 years, the total success rate of viscotrabeculotomy group was 89.74% compared to 85.53% in conventional trabeculotomy group without significant difference (p = 0.487). The postoperative mean values of the cup/disk ratio in viscotrabeculotomy group showed statistically lower values compared to conventional trabeculotomy group (p = 0.019). Postoperative hyphema was statistically higher in conventional trabeculotomy group (p < 0.0001). All eyes that underwent a reoperation before 5 years follow-up were excluded from the statistical workup of the study after reoperation, except for calculation of success/failure. Conclusion Viscotrabeculotomy and conventional trabeculotomy proved to be effective in cases of primary congenital glaucoma. Viscotrabeculotomy appeared to have prolonged stability in controlling the intraocular pressure with higher success rates and lower complications.

Purpose: To evaluate the long-term visual outcomes of ab externo trabeculotomy for primary congenital glaucoma (PCG) at a single pediatric ophthalmology center. Methods: In this retrospective single-center case series, data from 63 eyes of 40 patients who underwent ab externo trabeculotomy between September 2006 and June 2018 were included. The data were analyzed for best corrected visual acuity (BCVA), stereopsis, and surgical success. Kaplan–Meier analysis was performed using the surgical success criteria defined as intraocular pressure (IOP) ≤ 21 mmHg and ≥ 20% below baseline without the need for additional glaucoma surgery. Results: BCVA at the time of diagnosis was 0.37 ± 0.48 logMAR, which changed to 0.51 ± 0.56 logMAR at the final follow-up (P = 0.08). Twenty-five percent of patients had BCVA equal to or better than 20/40 at the final visit. The mean refraction at baseline was –4.78 ± 5.87 diopters, which changed to less myopic refraction of –2.90 ± 3.83 diopters at the final visit. Optical correction was prescribed in 66% of eyes at the final visit. The average final stereopsis was 395.33 sec of arc. The linear regression model showed a significant association between the surgery success rate and final BCVA as well as stereoacuity (Pvalues: 0.04 and 0.03, respectively). Intraocular pressure (IOP) decreased significantly from 29.79 ± 7.67 mmHg at baseline to 16.13 ± 3.41 mmHg at the final follow-up (P = 0.001). Conclusion: Patients with PCG can achieve an acceptable visual acuity and stereoacuity, particularly in cases of timely intervention and close follow-up.

Purpose: The purpose of this study was to report the long-term efficacy and clinical outcomes of microcatheter-assisted circumferential trabeculotomy (MCT) in children with primary congenital glaucoma (PCG). Methods: This is a single-center retrospective study including consecutive children with PCG who underwent MCT with > two years follow up. The primary outcome was surgical success, defined as intraocular pressure (IOP) ≤ 21 mmHg with (qualified) or without (complete) medications, measured at six months, one year, and then annually. Secondary outcomes were visual acuity (VA), refraction, axial length (AXL), complications, reinterventions, and number of medications. Results: Twelve eyes of ten patients were included. In eight children only one eye was affected. The mean ± standard deviation (SD) age at surgery was 6.3 ± 4.1 months. The mean postoperative follow-up was 66 ± 35 months. The mean IOP was 34.3 ± 9.6 mmHg preoperatively and 14.6 ± 2.3 mmHg postoperatively at the last visit (p < 0.001). Complete success was achieved at all time points in 10 out of 12 eyes, while 2 eyes had a qualified success. At three years of age, the mean VA of the operated eyes was 0.25 ± 0.12 logMAR, the mean spherical equivalent was −0.78 ± 1.43 diopters, and the mean AXL was 23.78 mm. Transient hyphema was the only complication observed. None of the children required additional glaucoma surgery. Conclusions: Circumferential trabeculotomy for PCG effectively lowers the IOP at more than two years after surgery. Following this procedure, the prognosis for the visual function is good, and the refractive error is low. Postoperative complications were not significant.

A 13-year-old female patient with refractory primary congenital glaucoma (PCG) in the right eye who had a history of multiple glaucoma operations underwent ab interno 180-degree trabeculectomy with the Kahook Dual Blade (KDB) targeting the nasal and inferior angles. On postoperative day 1, the intraocular pressure (IOP) of the right eye reduced from 43 to 15 mmHg while on medical therapy. The patient maintained this IOP level throughout the 6-month follow-up. Ab interno KDB trabeculectomy targeting both nasal and inferior angles may be an effective and safe procedure for the treatment of PCG even in eyes with a history of previously failed glaucoma procedures.

Objective: To assess incidence and risk factors of cataract extraction in patients with primary congenital glaucoma, surgical outcome, and complications. Material and method: Retrospective cohort study, in which 108 patients with primary congenital glaucoma were included. Data collected were need for cataract extraction and at what age, intraocular pressure at diagnosis of primary congenital glaucoma, required antiglaucomatous surgeries, possible mutation in the CYP1B1 gene, and final visual acuity. Among the patients who required cataract extraction were visual acuity, intraocular pressure, and complications, evaluated preoperatively and postoperatively. The data were analysed with STATA. Results: A total of 198 eyes of 108 patients were included, with a median follow-up of 8 years (range: 5–53). In all, 32 eyes (16.2%) of 24 patients (22%) required cataract extraction. The median age for cataract extraction was 12.94 years (interquartile range: 2.42–22). The main identified risk factors associated with cataract extraction were antiglaucomatous surgeries (hazard ratio 1.48, p < 0.001) and valvular implant (hazard ratio 2.78, p < 0.001). Lens was implanted in 30/32 eyes and the main complications were intraocular pressure decontrol ( n = 13), capsular fibrosis ( n = 7), corneal decompensation ( n = 4), lens subluxation ( n = 4), and endophthalmitis ( n = 1). Visual acuity improvement was observed after cataract extraction in 66.67% of eyes. Conclusions: There is a high incidence of cataract surgery in patients with primary congenital glaucoma, but generally outside of pediatric age. A greater risk of cataract extraction was identified in those patients with a greater number of antiglaucomatous surgeries, especially after valvular implantation. Despite the high rate of complications related to cataract extraction in primary congenital glaucoma, good visual improvement was observed after surgery.
