AIMS: To establish and evaluate predictive models for glaucoma-related adverse events (GRAEs) following secondary intraocular lens (IOL) implantation in paediatric eyes. METHODS: 205 children (356 aphakic eyes) receiving secondary IOL implantation at Zhongshan Ophthalmic Center with a 3-year follow-up were enrolled. Cox proportional hazard model was used to identify predictors of GRAEs and developed nomograms. Model performance was evaluated with time-dependent receiver operating characteristic (ROC) curves, decision curve analysis, Kaplan-Meier curves and validated internally through C-statistics and calibration plot of the bootstrap samples...

We assessed the 10-year postoperative outcomes of pediatric cataract patients who underwent surgery at the age of 6 years or younger. A retrospective review of medical charts was conducted for 457 eyes of 277 patients, with the age at surgery averaging 1.3 ± 1.5 years (mean ± SD) and the follow-up duration averaging 12.8 ± 2.4 years (ranging from 10 to 17 years). The cohort included 250 eyes of 125 cases with bilateral aphakia (age at surgery 0...

INTRODUCTION: The use of the neodymium:yttrium-aluminum-garnet (Nd:YAG) laser to treat malignant glaucoma (MG) has been described in the literature since the 1980s. However, the technique has been reported to have a short-term effect, with a notable relapse rate. In the present study, we report the efficacy and durability of a modified Nd:YAG laser treatment methodology for treatment of pseudophakic or aphakic MG. METHODS: Patients with chronic angle-closure glaucoma and deemed at high risk of developing post-operative MG received prophylactic peripheral iridectomy during their conventional operation beginning in 2017...

PURPOSE: To evaluate the clinical applicability of intraoperative predictors for surgical outcomes after gonioscopy-assisted transluminal trabeculotomy (GATT) and microincisional trabeculectomy (MIT). METHODS: Consecutive patients with primary, or secondary glaucoma (trauma, aphakic, or status post-retinal surgeries) with uncontrolled IOP>21mm Hg, who were scheduled to undergo GATT or MIT with or without significant cataract surgery, at a tertiary eye centre in East India between September 2021 to March 2023, were included...

PURPOSE: To report 5-year outcomes after surgery for cataract associated with persistent fetal vasculature (PFV). DESIGN: Clinical cohort study using pediatric cataract registry data collected annually from medical records. METHODS: This study included 64 children <13 years of age who were undergoing surgery for unilateral, nontraumatic cataract associated with PFV. Proportions with age-normal visual acuity (VA) and VA better than 20/200 at 5 years' follow-up were estimated...

Glaucoma Following Cataract Surgery (GFCS) remains a menace, so parents must be counseled prior to cataract removal in children. Age less than 7 months at the time of surgery increases this risk, and IOL placement has no effect. To lower IOP in GFCS, start with drops and before you escalate to surgery, consider phospholine iodide. Then, proceed cautiously with angle surgery and shunts, mixing in cycloablative procedures where appropriate in your hands. With patient-centered models for access, follow-up & adherence to treatment, GFCS can be controlled...

BACKGROUND AND OBJECTIVES: Descemet's stripping endothelial keratoplasty (DSEK) has emerged as the preferred method for posterior lamellar keratoplasty, as it enables the replacement of the compromised host endothelium with a viable donor lamella. The objective of this study was to assess the impact of DSEK on surgical outcomes and visual acuity. METHODS: The research was carried out from November 2019 to October 2021, encompassing a sample of 18 patients (18 eyes) who satisfied the inclusion criteria for DSEK...

PURPOSE: To evaluate the efficacy of XEN® -45 gel stent ab interno implantation for medically uncontrolled uveitic glaucoma. METHODS: Retrospective analysis of 25 eyes receiving XEN® gel stent for medically uncontrolled uveitic glaucoma from February 2019 to February 2023 with recording of intraocular pressure (IOP) values, ocular hypotensive medication, requirement for revision or secondary surgery and complications. Prerequisites for XEN® implantation were a clear cornea, an open iridocorneal angle and an unscarred, mobile conjunctiva at the implantation site...

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...

INTRODUCTION: After lens extraction, if the capsular bag insufficiency occurs, there are different IOL implantation techniques. IOL implantation in the posterior chamber is safer in eyes with low endothelial cell count, peripheral anterior synechiae, shallow anterior chamber, and glaucoma. Alternative approaches for scleral fixation techniques, both with and without sutures, continue to undergo development. In this study, we aimed to compare the postoperative outcomes of the sutured scleral fixation (SSF), haptic flanged intrascleral fixation (HFISF) and four flanged intrascleral fixation (FFISF) IOL implantation techniques in eyes with the absence of capsular support...

PURPOSE: Description of safety and efficacy of micropulse Transscleral cyclophotocoagulation as a treatment option for refractory glaucoma. METHODS: This is a prospective study including 39 eyes of 31 patients followed for refractory glaucoma, who benefited from transscleral cyclophotocoagulation using a microplused laser. The main indication for the procedure was increased ocular pressure refractory to quadritherapy in various types of glaucoma. The patients were treated using iridex Cyclo G6 laser with a Micropulse P3 infrared probe with a wavelength of 810 ​nm...

Unilateral congenital cataracts lead to deprivation amblyopia, which can be severe. Until the 1970s, they were believed to be always associated with poor visual outcomes. However, advances in our understanding of the plasticity of the infant brain and the development of better surgical techniques allowed good visual outcomes to be obtained in a few of these patients. The Infant Aphakia Treatment Study (IATS) was conducted to provide empirical evidence regarding the best type of optical correction to be used following surgical extraction of the cataract...

INTRODUCTION: The purpose of this study was to evaluate the capabilities of large language models such as Chat Generative Pretrained Transformer (ChatGPT) to diagnose glaucoma based on specific clinical case descriptions with comparison to the performance of senior ophthalmology resident trainees. METHODS: We selected 11 cases with primary and secondary glaucoma from a publicly accessible online database of case reports. A total of four cases had primary glaucoma including open-angle, juvenile, normal-tension, and angle-closure glaucoma, while seven cases had secondary glaucoma including pseudo-exfoliation, pigment dispersion glaucoma, glaucomatocyclitic crisis, aphakic, neovascular, aqueous misdirection, and inflammatory glaucoma...
