Abstract Background This study evaluates the efficacy and safety of micropulse transscleral cyclophotocoagulation (MP-CPC) in paediatric patients. Methods This retrospective case-series recruited 44 eyes for glaucoma patients who were younger than 17 years and were treated with MP-CPC and followed for at least one year. Pre- and post-intervention intraocular pressure (IOP) was compared out to at least one year postoperatively. Success rates at 6 months and 1 year postoperatively were assessed. P

Background: This study evaluates the efficacy and safety of micropulse transscleral cyclophotocoagulation (MP-CPC) in paediatric patients. Methods: This retrospective case-series recruited 44 eyes for glaucoma patients who were younger than 17 years and were treated with MP-CPC and followed for at least one year. Pre- and post-intervention intraocular pressure (IOP) was compared out to at least one year postoperatively. Success rates at 6 months and 1 year postoperatively were assessed. P < 0.05 was considered statistically significant. Results: There were 35 (79.5%) eyes with a history of glaucoma surgery. IOP decreased statistically significantly from a baseline of 32.7 (standard deviation:8.7 mmHg) to 23.2 (8.6) and 21.7 (7.9) mmHg at the 6 months and 1-year follow-up, respectively (P < 0.0001, all comparisons). Overall success was noted in 19 (47.5%) eyes at the 6 months follow-up, and 23 (53.5%) eyes at 1 year. Conclusions: MP-CPC reduces IOP and the burden of medications in paediatric patients with glaucoma. Additionally, its safety profile favours the use of MP-CPC as an adjunctive modality for refractory glaucoma. [ABSTRACT FROM AUTHOR]

Purpose: The PAUL® glaucoma implant (PGI) is a novel glaucoma drainage device, which has not been previously reported in paediatric glaucoma management. This study aims to evaluate the safety and effectiveness of the PGI in a paediatric cohort. Methods: A retrospective evaluation of 25 cases of paediatric PGI surgery (age 8 months to 16 years) was performed at Manchester Royal Eye Hospital between September 2019 and July 2020. Primary outcome measures included failure (intraocular pressure (IOP) > 21 mmHg or < 20% reduction of IOP, removal of the implant, further glaucoma intervention or visual loss. Secondary outcomes included mean IOP, mean number of medications, logMAR visual acuity and complications. Results: Eleven eyes (48%) had a complete success and achieved an unmedicated IOP < 21 mmHg, and 21 eyes (84%) had a qualified success (with or without medications). Four failures were observed, 2 due to hypotony and 2 underwent further surgery (gonioscopy-assisted transluminal trabeculotomy). The mean preop IOP was 30.9 ± 5.9 mmHg (n = 25), falling to 13.5 ± 6.8 mmHg at 1 month, 17.9 ± 7.2 mmHg at 3 months, 13.4 ± 5.1 mmHg at 6 months, 13.2 ± 4.9 mmHg at 12 months and 11.8 ± 4.6 mmHg at 24 months. The mean change in IOP from the preoperative visit to the last visit was a reduction of 19.1 ± 7.7 mmHg. A significant reduction in the number of medications and IOP was demonstrated after PGI (p < 0.0001). Nine patients required removal of the intraluminal Prolene stent from the PGI for further pressure lowering. Conclusion: The one- to two-year results demonstrate paediatric PGI has high qualified success rates and effectively reduces IOP and the need for glaucoma medical therapy. [ABSTRACT FROM AUTHOR]

Abstract Background The primary aim was to estimate the incidence of primary and secondary childhood glaucoma in Scotland over a 2-year period. The secondary aim was to gauge the confidence and experience of ophthalmologists in Scotland in managing these patients. Methods A 7 question electronic survey was distributed to all consultant members of the Scottish Paediatric Club and Scottish Glaucoma Club. Respondents were asked to report the number of cases and types of childhood glaucoma they had managed in the last 2 years. Respondents were also asked about experience and confidence in a range of glaucoma procedures, number of patients requiring referral to specialist centres and interest in the development of a centre of excellence in Scotland. Results The survey returned a 56% response rate, reporting 85 new cases of paediatric glaucoma in Scotland over the preceding 2 years. 11 (12.9%) had primary glaucoma and 74 (87.1%) had secondary glaucoma. The most common subtype of secondary glaucoma was uveitic glaucoma (n = 29). None of the respondents declared confidence or experience in trabeculotomy or goniotomy procedures. Eleven children required referral to a specialist unit outside Scotland. 85.7% of respondents felt Scotland would benefit from a specialist unit for paediatric glaucoma. Conclusions This survey reflects an appetite for a specialist service for paediatric glaucoma in Scotland. However, further consideration is needed to determine if there is sufficient patient load to maintain such a service.

Purpose: To evaluate the clinical characteristics and treatment outcomes of patients with childhood glaucoma. Methods: We retrospectively reviewed the data of patients with childhood glaucoma who visited the glaucoma clinics at the Queen Sirikit National Institute of Child Health and the King Chulalongkorn Memorial Hospital between January 2008 and January 2018. The diagnosis was based on the Childhood Glaucoma Research Network classification. We recorded their clinical characteristics and requirement of any glaucoma interventions. Results: A total of 691 eyes from 423 patients were included in this study. The patients predominantly comprised boys. The average follow-up duration was 71.3±63.8 months. The mean age at presentation was 3.9±4.4 years. Most patients presented with a high initial intraocular pressure (IOP). The average intial IOP of all patients was 28.5±11.2 mmHg. Glaucoma associated with non-acquired ocular anomalies (22.9%) was the most common subtype, followed by primary congenital glaucoma (20.8%). We recorded a family history of glaucoma in 6.4% of patients of the 234 patients with an available family history. Most patients had bilateral glaucoma (63.4%) and required at least one intervention (51.5%). The average IOP at the latest follow-up visit was 19.1±10.8 mmHg. All glaucoma types had significantly lower IOP, compared to that at their baselines (all p Conclusions: Secondary glaucoma associated with non-acquired ocular anomalies is the most common subtype of glaucoma. The majority of patients had unfavourable visual outcomes. These real-world findings are fundamental to acquire a better understanding of childhood glaucoma.

Purpose: To evaluate the epidemiological features, clinical interventions, and outcomes of paediatric glaucoma in Hong Kong. Study design: Retrospective chart review. Methods: Clinical data from the medical records of all patients under 18 years of age diagnosed with glaucoma from January 2008 to December 2017 at a university-affiliated, tertiary referral centre were collected. The patients' demographics, etiological distribution, clinical interventions, and outcomes were analysed. Results: A total of 33 subjects (53 eyes) were identified, 30 (49 eyes) of whom were Chinese. Primary glaucoma accounted for 21.2% of subjects, while 78.8% were diagnosed with secondary glaucoma. The most common subtype was juvenile-onset open angle glaucoma, followed by Sturge-Weber Syndrome related glaucoma. The most commonly performed surgical interventions were tube-shunt surgery (Ahmed Glaucoma Valve) and transscleral cyclophotocoagulation. Most eyes had significant reduction in intraocular pressure after medical or surgical intervention, but deterioration of visual acuity remained common. Conclusion: Most cases of childhood glaucoma in Hong Kong are secondary rather than primary, similar to other regions with low incidence of parental consanguinity. The large proportion of secondary glaucoma which generally has poorer prognosis, is reflected by the frequency of multiple surgery, and a high incidence of visual deterioration despite significant intraocular pressure reduction in most eyes.

Purpose: To investigate the role of early and prolonged administration of aqueous suppressants in reduction of hyperencapsulation and intraocular pressure (IOP) control after paediatric Ahmed glaucoma valve (AGV) implantation. Methods: A prospective randomized interventional study recruited children who had AGV implantation for paediatric glaucoma. All patients received postoperative Timolol 0.5% for either 12 months (Group A) or 3 months (Group B). Additional IOP‐reducing medications were added if IOP exceeded 21 mmHg or hyperencapsulation developed in either group. Primary outcome measures were rate of hyperencapsulation and reduction of IOP. Results: Eighty sex children completed the 12‐month follow‐up visits. Baseline IOP was significantly reduced from 31.95 ± 9.1 to 16.94 ± 3.4 mmHg at 12 months in Group A and from 32.7 ± 7.4 to 19.85 ± 6.9 mmHg at 12 months in Group B. IOP was significantly lower in Group A than B at 6‐, 9‐ and 12‐month follow‐up visits. In the first 4 months, the hyperencapsulation rate was similar in both Group A (six eyes, 13.3%) and Group B (seven eyes, 17.1%). However, the hyperencapsulation rate was significantly lower in Group A than B at both 6 months (22.5% versus 36.6%) and 12 months (31.1% versus 46.3%). Anti‐glaucoma medications were significantly lower in Group A than B at both 6 months (1.3 versus 3.2 drugs) and 12 months (1.5 versus 3.6 drugs). Conclusion: Early and prolonged use of aqueous suppressants significantly reduced the rate of hyperencapsulation and provided better IOP control after paediatric AGV implantation.

Aim To determine the incidence and predictors of glaucoma following surgery for congenital and infantile cataract in an Australian population. Design Retrospective cohort study. Participants Infants (<12 months) having had lens extraction between January 1992 and May 2006, from two tertiary referral centres. Methods Children with uveitis, anterior segment dysgenesis, aniridia, retinopathy of prematurity, and lens subluxation were excluded. Potential predictors of incident glaucoma were examined using Cox proportional hazards regression with adjustment for clustering between eyes. Main Outcome Measures Incidence and predictors of secondary glaucoma. Results One hundred and forty-seven eyes of 101 patients (46 bilateral cataract; 55 unilateral cataract) were included, with median follow-up of 9.9 years (range 1.2-18.9 years). Cumulative incidence of glaucoma was 32.0% for eyes ( n = 47) and 30.7% ( n = 31) for subjects. Incidence was higher in children with bilateral cataract (38.9 vs. 17.1%, p = 0.004). There were 3.9 cases of glaucoma per 100 person years of follow-up, the incidence rate being highest for surgery performed in the first month of life. Children with glaucoma had longer median follow-up (11.8 vs. 9.3 years, p = 0.005). Risk of glaucoma decreased with increasing months of age at operation: hazard ratio 0.79, 95% confidence interval 0.69-0.91, p = 0.001. Median visual acuity was worse in children with unilateral cataract ( p < 0.001). Conclusions We identified an increased risk of glaucoma when cataract surgery was performed in younger infants, and in those with bilateral cataract. As glaucoma may develop over a decade following lens extraction, life-long surveillance is needed to prevent glaucoma-associated vision loss. [ABSTRACT FROM AUTHOR]

PurposeTo evaluate clinical outcomes after Ahmed valve implantation in refractory paediatric glaucoma.MethodsA retrospective review was conducted on 34 eyes from 29 patients with refractory glaucoma, who were younger than 18 years of age and who underwent Ahmed valve implantation. The main outcome measures were intraocular pressures (IOPs) and the number of glaucoma medications used. Qualified success was defined as IOP 21 mm Hg regardless of the number of glaucoma medications. Complete success was defined as IOP 21 mm Hg without glaucoma medication.ResultsMean age at operation was 5.5 years (range, 0–16). Fifteen eyes (44.1%) had undergone previous glaucoma surgery before Ahmed valve implantation. Mean follow-up time was 29.1 months (range, 3–31). IOP was reduced from a preoperative mean of 37.5±7.3 to 18.4±7.3 mm Hg at 6 months postoperatively (P<0.01). At 12 months after surgery, the success rates were 63.3% (qualified success) and 13.3% (complete success). The cumulative probabilities of qualified success at 6, 12, and 24 months after Ahmed valve implantation were 89.0, 68.6, and 45.7%, respectively. The median time of survival was 19.6±0.9 months.ConclusionsAhmed valve implantation is effective in lowering IOP in refractory paediatric glaucoma, with limited survival after long-term follow-up. Addition of a second Ahmed valve may be effective in the management of failure after primary implantation.Eye (2009) 23, 1427–1435; doi:10.1038/eye.2008.261; published online 29 August 2008 [ABSTRACT FROM AUTHOR]

The paediatric glaucomas present some of the greatest clinical challenges. We review the advances in the management of the paediatric glaucomas, which have improved the outlook for these patients and their families. These advances include improvements in diagnosis, investigations, anaesthetic techniques, medical, surgical, and laser therapies.Eye (2007) 21, 1319–1325. doi:10.1038/sj.eye.6702850 [ABSTRACT FROM AUTHOR]

Abstract Corticoteroid-induced glaucoma can result from either topical or systemic corticosteroid use. Compared with adults, the corticosteroid response in children is less well known. The case is reported of a child who developed glaucoma after receiving topical corticosteroids following a scleral re­inforcement procedure. The raised intraocular pressure was controlled after cessation of the corticosteroids and with the use of antiglaucoma therapy. As many forms of cortico­steroids are widely used, children on corticosteroids should have regular intraocular pressure measurements as part of their management. [ABSTRACT FROM AUTHOR]

Case Report: The case concerns a 22 day-old male child with juvenile xanthogranuloma (JXG), which manifested as a unilateral glaucoma and with fibrinous haemorrhagic exudate in the anterior chamber affecting the angle of the right eye. Despite a high level of suspicion, the definitive diagnosis was not possible until the infant reached the age of 10 months, after the appearance of the skin lesions typical of this condition and histopathological study of them., Conclusion: JXG is a rare disease, characterised by yellowish skin lesions on the trunk, neck, or head. Up to 10% of cases will have ocular involvement, which is the most common extracutaneous manifestation of the disease., (Copyright © 2017 Sociedad Española de Oftalmología.
