“…Shi et al reported the success rate was 86.4% in a retrospective comparison of catheter-assisted trabeculotomy and traditional trabeculotomy with the same definition of success (Shi et al 2016). Park JH reported the success rate of 180degree suture trabeculotomy at 1, 3 and 5 years was 95.0%, 87.7% and 78.9%, respectively, and the success was defined as IOP < 22 mmHg and no evidence of progressive optic disc cupping (Park et al 2016). Lower cut-off of IOP was also reported in the literature, with reported success rate all around 90% (Temkar et al 2015;El Sayed & Gawdat 2017;Shakrawal et al 2017).…”

Purpose To compare the efficacy and safety of viscocanalostomy plus near‐360‐degree suture trabeculotomy (VST) with viscocanalostomy plus rigid probe trabeculotomy (VT) in treating primary congenital glaucoma (PCG) over a one‐year follow‐up. Methods This consecutive retrospective study included patients with PCG confirmed within 3 years of age from March 2017 to October 2019. Efficacy was evaluated by comparing the postoperative intraocular pressure (IOP) curve and the success rate at one year after surgery. Safety was assessed by comparing the postoperative complications. The number of anti‐glaucoma agents, horizontal corneal diameter (HCD) and cup‐to‐disc ratio (C/D) of the two surgical methods were also compared. Results Data of 90 eyes from 61 patients were analysed. The baseline parameters of the two groups were similar. The IOP at 12 months after surgery in the VST group was 12.7 ± 4.8 mmHg, while that in the VT group was 15.8 ± 6.5 mmHg. The IOP at 6, 9 and 12 months postoperatively in the VST group was significantly lower than in the VT group (p < 0.05). Viscocanalostomy plus near‐360‐degree suture trabeculotomy (VST) remained a significant favourable factor for complete one‐year success (93.6% versus 74.4%, p = 0.005) but not qualified one‐year success (97.9% versus 88.4%, p = 0.06). The number of anti‐glaucoma agents, HCD and C/D were reduced in both groups. Postoperative complications were not significantly different between the two groups. Conclusions In children with PCG, VST provides a more durable IOP control than VT over the one‐year follow‐up, with a similar safety profile.

“…It is well known that all signs and symptoms become intense and progress as the disease duration increases, which is a strong reason to perform TROC as soon as possible. In the first 6 months, the eyes of a child are more distensible than after 6 months of age due to low ocular rigidity and might suffer corneal, and iris changes as a consequence of elevated IOP (Huang et al, 2016; Kornblueth et al, 1962; Park et al, 2016; Sampaolesi & Caruso, 1982). Low ocular rigidity, mainly until 60 days of life, provides low resistance, consequently enhancing the penetration of the trabeculotome into Schlemm's canal.…”

Purpose In patients with primary congenital glaucoma (PCG), elevated intraocular pressure (IOP) causes abnormal eye growth. This study compared the outcomes of children with PCG who underwent ab externo trabeculotomy (TROC) at age ≤ 6 months (early TROC) and of those who underwent TROC at age > 6 months (delayed TROC). Methods Intraocular pressure, horizontal corneal diameter (HCD), central corneal thickness (CCT) and axial length (AL) were compared before TROC and at 1‐, 3‐, 6‐ and 12‐month follow‐up visits between the groups of children who underwent TROC until or after 6 months of age. The ALs of these groups were also compared with the ALs of healthy age‐matched eyes examined under the same conditions. Results Trabeculotomy was performed in 43 children: 18 (33 eyes) aged 6 months (group 1) and 25 (37 eyes) aged >6 months (group 2); the mean ages were 86.56 ± 53.64 and 504.48 ± 448.14 days, respectively. The mean pre‐ and 12‐month postoperative IOP values were 15.97 ± 4.78/16.62 ± 4.85 and 9.77 ± 2.88/10.93 ± 4.83 mmHg, respectively. Delayed TROC was associated with abnormal AL in 31 (88.6%) out of 37 eyes, while after early TROC, only 13 (41.9%) out of 33 eyes had abnormal AL (chi‐square, 8.00; p = 0.03). In multivariable analysis, each 1‐mmHg increase in preoperative IOP was associated with a 0.25‐mmHg increase at 12 months (p = 0.04). On average, the mean IOP of the delayed TROC group was higher than that of the early TROC group by 3.72 mmHg at postoperative month 12 (95% CI = 0.44–6.99; p = 0.02). Conclusion Compared with delayed TROC, early TROC is associated with reduced IOP and substantially reduced incidence of abnormal AL at postoperative month 12.

“…7 Different techniques of CT are now available in PCG management with improved success including illuminated microcatheter-assisted CT, 360degree suture trabeculotomy, visco-circumferential-suturetrabeculotomy (VCST), and rigid-probe double-entry trabeculotomy. [10][11][12][13][14] Therefore, in PCG patients CT may be considered a first-line surgery, and rigid-probe trabeculotomy is reserved as an alternative surgery if CT fails. 7 Several studies revealed that younger age at the time of surgery might contribute to the surgical failure-perhaps related to the more severe disease in the very early-onset cases-and therefore it may be wise to postpone surgery in such young infants until after the first month of age to increase the chances of success.…”

“…Circumferential trabeculotomy (CT) provides complete rupture of the TM and Schlemm canal (SC) inner wall, with better improvement in IOP reduction than rigid-probe single-entry trabeculotomy 7 . Different techniques of CT are now available in PCG management with improved success including illuminated microcatheter-assisted CT, 360-degree suture trabeculotomy, visco-circumferential-suture-trabeculotomy (VCST), and rigid-probe double-entry trabeculotomy 10–14 . Therefore, in PCG patients CT may be considered a first-line surgery, and rigid-probe trabeculotomy is reserved as an alternative surgery if CT fails 7 .…”

Précis: Angle procedures are safe and relatively effective for neonatal onset PCG. Watchful delay in intervention to close to the second month of life is helpful in ensuring diagnosis and making surgery more successful and easier. Purpose:The purpose of this study was to compare the surgical outcomes of visco-circumferential-suture-trabeculotomy (VCST) to rigid-probe double-entry viscotrabeculotomy (DEVT) and rigidprobe single-entry viscotrabeculotomy (SEVT) in infants with neonatal-onset primary congenital glaucoma (PCG).Design: This was a retrospective chart review. Patients and Methods: Retrospective chart review of 64 eyes of 64 infants with neonatal-onset PCG referred to Mansoura Ophthalmic Center in Mansoura, Egypt between February 2008 and November 2018. Study groups included VCST, DEVT, and SEVT, and followup covered 4 postoperative years. Complete (qualified) success was defined as intraocular pressure (IOP) ≤ 18 mm Hg and with 35% IOP reduction from baseline without (with) IOP-lowering medications or further surgical interventions, and without any sign of progression in corneal diameter, axial length, or optic disc cupping and without visual devastating complications.Results: The mean ± SD age at presentation and at the surgery of the study children was 3.63 ± 1.74 and 55.23 ± 1.60 days, respectively. The mean ± SD IOP and cup/disc ratio of all study eyes at presentation and at final follow-up were 34.91 ± 0.82 mm Hg and 0.70 ± 0.09 and 17.04 ± 0.74 mm Hg and 0.63 ± 0.08, respectively. Complete success was achieved in 54.5%, 43.5%, and 31.6% in the VCST, DEVT, and SEVT groups, respectively. A self-limited hyphema was the commonest complication in all groups.Conclusions: Angle procedures are safe and marginally effective for the surgical treatment of neonatal-onset PCG, bringing IOP under control for at least 4 years of follow-up. Circumferential trabeculotomy as a first-line treatment has more favorable outcomes than rigid-probe SEVT. Rigid-probe viscotrabeculotomy offers an alternative to the noncompleted circumferential procedure.
