Purpose: We aimed to evaluate the efficacy and safety of effective goniosynechialysis (GSL) under an endoscopic view combined with phacoemulsification in residual angle-closure glaucoma with lens opacity.
Methods: This was a retrospective study. Patients with residual angle-closure glaucoma, lens opacity, and uncontrolled intraocular pressure (IOP) who were receiving anti-glaucoma medications were selected to undergo effective GSL under an endoscopic view combined with phacoemulsification. Follow-up examinations were conducted until 6 months postoperatively.
Results: Twenty-five eyes of 24 patients diagnosed with residual angle-closure glaucoma and lens opacity and peripheral anterior synechiae (PAS) at least ≥ 270° were included. Their mean age was 61.32 ± 6.11 years. Preoperatively, the mean (standard error) IOP was 29.69 (11.22) mmHg, and the median number of IOP-lowering medications used was 3.0. The decreases in the rates of IOP of the patients were 44.29%, 52.17%, 46.95%, 48.37%, and 47.29% at 1 day, 1 week, 1 month, 2.5 months, and 6 months after the surgery, respectively. At 6 months, the median number of IOP-lowering medications used decreased from 3 to 0 and the range of PAS compared to the baseline decreased from 312° to 107° (P < 0.001). We also found that 21/25 eyes achieved improved or stable visual acuity after surgery. Postoperative complications included transiently elevated IOP (12.0%), exudation (8.0%), and hyphema (4.0%).
Conclusions: Phacoemulsification combined with effective GSL under an endoscopic view may reopen residual angle-closure glaucoma and reduce the number of IOP-lowering medications for up to 6 months. It is an effective and safe method for patients with residual angle-closure glaucoma and lens opacity.

Purpose: This study compares and evaluates the parameters of iridotrabecular contact (ITC) in patients with primary angle closure disease (PACD) with natural lenses and pseudophakia based on anterior segment imaging data from swept-source optical coherence tomography (SS-OCT).
Material And Methods: This retrospective study analyzed data from 92 patients aged 32 to 89 years, and included 56 patients with PACD (43 with natural lenses and 13 with pseudophakia) and 36 in the control group (21 with natural lenses and 15 with pseudophakia). All participants underwent SS-OCT (CASIA2; Tomey Corporation, Japan), which included an assessment of the ITC Index and ITC Area.

Introduction: Idiopathic congenital acorea is extremely rare. There are several techniques for preserving the clear lens during pupil formation.
Case Presentation: The complete pupil absence caused acute glaucoma attack 2 weeks after birth, which was controlled in a 1-month-old child by peripheral iridectomy and disconnecting iris-corneal synechias.

Article Synopsis
- Iris cysts can cause a range of serious eye issues, so their complete removal is crucial to prevent recurrence and improve patient outcomes.
- A new three-step technique was developed for managing iris cysts, which includes aspiration, wall removal, and cauterization while minimizing tissue damage.
- This minimally invasive approach led to fewer complications, no reported recurrences in six months, and overall better visual outcomes compared to more aggressive treatments.

Purpose: To compare changes in the swept-source (SS) anterior-segment optical coherence tomography (AS-OCT) parameters and intraocular pressure (IOP) control after lens extraction in various spectra of primary angle-closure disease (PACD).
Methods: A total 92 eyes from 92 patients with PACD who underwent lens extraction were included in the study. All patients underwent IOP measurement preoperatively and at 1 day, 1 week, and 1, 3, and 6 months postoperatively.

Singapore Eye Research Institute, Singapore National Eye Centre, Singapore.
Article Synopsis
- - The study aimed to create and validate a deep learning algorithm to automate the annotation of the scleral spur and segmentation of anterior chamber structures in OCT scans, enhancing measurement accuracy for eye parameters.
- - It utilized data from multiple studies on angle-closure disease and employed advanced imaging techniques and specialized neural networks to improve the precision of automated measurements compared to manual methods.
- - Results showed high reliability, with the algorithm achieving a low error rate for scleral spur annotation and excellent similarity in structure segmentation, indicating that automated measurements were closely aligned with those made by human experts.
