Li L, Wang X, Liu C, Wang S, Wang X. Incidence Rate of Secondary Glaucoma Following Congenital Cataract Surgery: An In-Depth Systematic Review and Meta-Analysis. Am J Ophthalmol 2024; 265:176-188. [PMID: 38679355 DOI: 10.1016/j.ajo.2024.04.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Revised: 04/17/2024] [Accepted: 04/22/2024] [Indexed: 05/01/2024]
Abstract
PURPOSE To assess the incidence of secondary glaucoma in children following congenital cataract surgery. DESIGN Systematic review and meta-analysis. METHODS The PubMed, Embase, Cochrane Library, and Web of Science databases were searched from inception through March 16, 2023. Studies reporting congenital cataract surgery and glaucoma were enrolled. The quality of the selected studies was assessed using the Newcastle Ottawa Scale, and data analysis was executed utilizing R software. RESULTS A total of 36 published studies with 3151 patients (4717 eyes) were included in the analysis. The incidence rate of glaucoma following congenital cataract surgery was 6.6% (95% CI: 3.9%, 9.9%). The incidence of secondary glaucoma in the primary intraocular lens (IOL) implantation group (3.3% [95% CI: 1.5%, 5.8%]) and the secondary IOL implantation group (3.5% [95% CI: 0%, 11.4%]) were lower compared to the aphakia group (13.5% [95% CI: 7.7%, 20.6%]). The incidence rate among children with congenital cataracts from Asia (6.9% [95% CI: 4.1%, 10.4%]) was higher than that in European children (0.9% [95% CI: 0%, 3.0%]; P < .01). A correlation was identified between the age at cataract surgery and the incidence of secondary glaucoma (P = .02). CONCLUSIONS This meta-analysis found that the incidence of secondary glaucoma following congenital cataract surgery is approximately 6.6%. Children with IOL implantation exhibit a lower incidence of secondary glaucoma, with a lower incidence noted in European children compared to their Asian counterparts. The age at cataract surgery is an important risk factor to consider.

Abstract
For four decades, investigations of the biological basis of critical periods in the developing mammalian visual cortex were dominated by study of the consequences of altered early visual experience in cats and nonhuman primates. The neural deficits thus revealed also provided insight into the origin and neural basis of human amblyopia that in turn motivated additional studies of humans with abnormal early visual input. Recent human studies point to deficits arising from alterations in all visual cortical areas and even in nonvisual cortical regions. As the new human data accumulated in parallel with a near-complete shift toward the use of rodent animal models for the study of neural mechanisms, it is now essential to review the human data and the earlier animal data obtained from cats and monkeys to infer general conclusions and to optimize future choice of the most appropriate animal model. Expected final online publication date for the Annual Review of Vision Science, Volume 8 is September 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

The effect of retaining intact posterior capsule in congenital cataract surgery in children aged 4-8 years. BMC Ophthalmol 2021; 21:332. [PMID: 34511057 PMCID: PMC8436493 DOI: 10.1186/s12886-021-02098-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2021] [Accepted: 09/01/2021] [Indexed: 11/18/2022] Open
Abstract
Background The present study sought to observe the effect of retaining intact posterior capsule in congenital cataract surgery in children aged 4–8 years. Methods This is a retrospective case control study. Seventy-seven children (130 eyes) aged from 4 to 8 years who underwent cataract surgery were divided into two groups. In Group A, 50 eyes underwent phacoemulsification, intraocular lens implantation and posterior capsule capsulotomy combined with anterior vitrectomy. In Group B, 80 eyes underwent cataract phacoemulsification and intraocular lens implantation. The postoperative visual acuity and the rate of complications were compared. Results In all patients, cataract surgeries were performed evenly without intraoperative complications. The follow-up time ranged from 6 months to 42 months. No apparent visual axis opacity was detected in group A during the follow-up. By the last visit, apparent visual axis opacity was detected in 31 eyes (38.75%) in group B. Among them, 9 eyes (29.03%) with mild posterior capsule opacification (PCO) were treated with Nd:YAG laser, 3 eyes (9.68%) with thick proliferative membranes were treated with posterior capsule capsulotomy combined with anterior vitrectomy and proliferative membranes in 19 eyes (61.29%) were completely aspired and the posterior capsule was retained. During follow-up, only 2 (6.45%) eyes had PCO recurrence and were treated with Nd:YAG laser. The visual acuity was significantly higher than that before surgery in all patients. Conclusions For older children, the incidence of PCO will be low even if intact posterior capsule is retained. Either Nd:YAG laser or surgical treatment for PCO will be able to maintain good vision.

Abstract
Purpose To study the safety of sutureless cataract surgery and risk factors for wound leak of clear corneal incision in children affected with congenital or developmental cataract. Methods It is a retrospective, noncomparative interventional case study involving children in the age group of 2 to 16 years, who underwent cataract surgery with intraocular lens implantation with the minimum follow up of 1 month. Results Out of 1000 eyes studied, lens matter aspiration with intraocular lens implantation with or without primary posterior capsulorhexis and anterior vitrectomy was done in 609 and 391 eyes, respectively. Incisions of 943 eyes did not require sutures while sutures were applied for wound leak in 57 eyes on the table and in 5 eyes on postoperative day 1. Risk of wound leak for suture application was found to be greater in patients; having age less than 5 years (P < 0.0001), surgeries performed by junior surgeons (P < 0.0003), wound problems (P < 0.0001), intraocular lens (IOL) related factors (P < 0.0001), use of iris hooks (P < 0.0001), and anterior capsulorhexis extension (P < 0.0001). On the first postoperative day, anterior chamber reaction (P < 0.0001) and fibrinous membrane (P = 0.0007) were significantly more in the sutured group. Incidence of postoperative complications was 0.98 per sutured eyes (59 complications in 60 eyes). One patient developed endophthalmitis after suture removal. Conclusion Sutureless clear corneal incision in pediatric patients undergoing cataract surgery can achieve stable wound. However, after hydro closure, every wound should be checked for water tightness and the leaky wound should be sutured.

Abstract
INTRODUCTION The leading cause of childhood blindness globally is paediatric cataract. Bilateral cataract surgery can help to improve visual performance and to diminish the burden of childhood blindness. OBJECTIVE To report in a retrospective observational cohort study the long-term outcomes of 298 children who had bilateral cataract surgery with IOL implantation from 2001-2016 in Kinshasa. METHODS A standardized surgical treatment of paediatric cataract was practiced on 298 children. Patient's follow-up, complications, and visual outcomes were recorded and analysed. RESULTS The mean age was 5.7 ± 4.3 years and males were predominant (64.9%). Most of children were living mainly in urban poorest areas (96.3%). Strabismus, nystagmus and microcornea were encountered in 20.1%, 25.1% and 8.7% of children, respectively. Using WHO criteria most of patients were classified as blind preoperatively and 81.9% of them had improved visual outcomes after surgery. Main reasons for reduced vision during follow-up were secondary cataract (5.7%), IOL decentration (1.2%), retinal detachment (1.2%), and secondary glaucoma (1.5%). CONCLUSION In spite of the post conflict challenges, elimination of cataract blindness in children remains a priority. Children present at a late age for surgery and long term follow-up is poor. There is need for program strengthening in these areas.

Abstract
Purpose To find out the sociodemographic, sociocultural, and socioeconomic factors leading to delay in pediatric cataract surgery and its impact on final visual outcome. Methods A prospective interview-based analytical cohort study was conducted on 156 children aged 0-16 years with either unilateral or bilateral congenital/developmental cataracts. Caregivers were interviewed using a pretested validated questionnaire. Time intervals between recognition by a caregiver to consultation were denoted as Delay-1 and between consultations to surgical intervention as Delay-2. Spearman's rank correlation was used to determine the presence of correlation between causes of delay and visual outcome. Results The mean age of presentation was 7.78 ± 4.34 years. Mothers were the first informant of the problem (n = 110, 70.5%). Out of 156 children, only 8 (5.1%) children presented to the hospital within 1 month by caregivers and 26 (16.7%) children underwent surgery within 2 months of advice. About 22 (14.1%) children had total cumulative delay of 1-6 months, 11 (7%) had delay of 6-12 months, and 115 (73.71%) had delay of >12 months. The most common cause identified for Delay-1 was unawareness in 41 cases (26.28%), however, for Delay-2 major factor responsible was cost (n = 38, 24.35%). The median preoperative visual acuity was 1.31 logMAR and median postoperative visual acuity at 4 weeks was 0.61 logMAR. (P < 0.001) Less age at surgery, upper socioeconomic status, less time delay, and better preoperative vision were positively correlated to better visual outcomes. Conclusion Delay in presentation for childhood cataract surgery remains a significant problem in central rural India. Delay in surgery is multifactorial which includes unawareness, cost, misdiagnosis, self-treatment, distance from the hospital, lack of family support, and poor socioeconomic status.

Abstract
Children who are treated for congenital cataracts later exhibit impairments in configural face analysis. This has been explained in terms of a critical period for the acquisition of normal face processing. Here, we consider a more parsimonious account according to which deficits in configural analysis result from the abnormally high initial retinal acuity that children treated for cataracts experience, relative to typical newborns. According to this proposal, the initial period of low retinal acuity characteristic of normal visual development induces extended spatial processing in the cortex that is important for configural face judgments. As a computational test of this hypothesis, we examined the effects of training with high-resolution or blurred images, and staged combinations, on the receptive fields and performance of a convolutional neural network. The results show that commencing training with blurred images creates receptive fields that integrate information across larger image areas and leads to improved performance and better generalization across a range of resolutions. These findings offer an explanation for the observed face recognition impairments after late treatment of congenital blindness, suggest an adaptive function for the acuity trajectory in normal development, and provide a scheme for improving the performance of computational face recognition systems.

Abstract
Purpose To determine and to analyze the outcome of pediatric cataract surgery. Methods A retrospective chart review of individuals aged up to 10 years who underwent cataract surgery between January 1, 2004, and December 31, 2014, at the UniversityHospital Zurich, Switzerland. Results 63 children (94 affected eyes) with bilateral (68/94) or unilateral (26/94) cataract were identified. Surgery was performed at a median age of 1.5 months (IQR: 1.3–2.6 months) for the aphakic group (45/94) and of 50.7 months (IQR: 38.0–78.4 months) for the IOL group (49/94). At the last follow-up visit (median 31.1 months, IQR: 18.4–50.2 months), visual acuity was better in bilateral than in unilateral cataract cases. Posterior capsular opacification (PCO) was diagnosed in 30.9% of eyes without a significant difference in the IOL and aphakic groups (p = 0.12). Aphakic glaucoma was diagnosed in 12/45 eyes at a median of 6.8 months (IQR 2.1–13.3 months) after surgery. Microcornea (5/12) and anterior segment anomalies (8/12) were associated with glaucoma development (p < 0.05). Conclusion Laterality and timing of surgery influence the outcome of pediatric cataract surgery. PCO was the most frequent postoperative complication. Aphakic glaucoma is often associated with ocular developmental abnormalities and a poor visual outcome.
