AI Article Synopsis
- The study aimed to investigate changes in the iridocorneal angle following pediatric cataract surgery in children.
- A total of 64 eyes from 41 children were analyzed through gonioscopic examinations before and after the surgery, revealing significant increases in trabecular meshwork pigmentation and other anatomical features post-operation.
- The results showed a gradual increase in intraocular pressure (IOP) after surgery, which ultimately correlated positively with changes in trabecular meshwork pigmentation and iris processes.
Article Abstract
Aim: To evaluate morphological changes in the iridocorneal angle after pediatric cataract surgery.
Methods: Children who underwent primary infantile cataract surgery were included and 64 eyes from 41 children, including 18 with unilateral cataracts (18 eyes) and 23 with bilateral cataracts (46 eyes) were examined. All patients underwent two gonioscopic examinations to evaluate the iridocorneal angle, before the primary lens removal and before the secondary intraocular lens implantation. The anatomical changes in the iridocorneal angle and the relationship between intraocular pressure (IOP) and iridocorneal angle changes were also analyzed.
Results: The iridocorneal angle was wide in 64 eyes before and after surgery. The trabecular meshwork pigmentation, number of iris processes in every quadrant of the iridocorneal angle, and the width of the ciliary body band in the superior and inferior quadrants at the second gonioscopic examination were significantly increased compared to those at the first examination (<0.001, <0.05, <0.05, and <0.05, respectively). IOP gradually increased at 1mo after operation, and returned to the preoperative level at 3mo. However, IOP still increased significantly at 6 and 12mo.
Conclusion: The main changes after pediatric cataract surgery include an increase in trabecular meshwork pigmentation and number of iris processes, IOP gradually increase and has positive correlation with trabecular meshwork pigmentation and anterior insertion of iris process.

Quantitative analysis of iridocorneal angle and ciliary cleft structures in canine eyes using ultrasound biomicroscopy.
Front Vet Sci

Laboratory of Veterinary Surgery and Ophthalmology, College of Veterinary Medicine, Chungbuk National University, Cheongju, Republic of Korea.
Introduction: This study aimed to examine the relationship between the relative opening of the ICA (RO-ICA) and the structure of the ciliary cleft (CC) using Ultrasound Biomicroscopy (UBM).
Materials And Methods: Clinical data from 31 eyes of 17 dogs at the Veterinary Teaching Hospital of Chungbuk National University, Korea, were analyzed. RO-ICA was categorized as "Slightly Narrow", "Narrow", "Open", and "Wide Open", with eyes further grouped into "Narrow" (including Slightly Narrow and Narrow) and "Open" (including Open and Wide Open) for analysis.
Intermittent Bleeding from the Iridocorneal Angle and Subsequent Ghost Cell Glaucoma Following Gonioscopy-Assisted Transluminal Trabeculotomy: A Case Report.

Kartal Dr. Lütfi Kırdar City Hospital, Department of Ophthalmology, Istanbul, Turkey.
Purpose: This study aims to present a case involving intermittent bleeding from the iridocorneal angle following gonioscopy-assisted transluminal trabeculotomy (GATT) surgery, followed by the development of ghost cell glaucoma (GCG).
Methods: A 25-year-old man with a history of post-traumatic angle recession glaucoma underwent uneventful 360° GATT surgery.
Results: Two weeks after the surgery, while the reason for the incomplete resolution of hyphema remained unclear, intermittent bleeding from the iridocorneal angle and hemorrhage in the inferior vitreous were observed during the patient's follow-up examination.

Department of Ophthalmology, Ankara Bilkent City Hospital, Ankara, Turkey.
Purpose: To investigate the potential effects of systemic fingolimod treatment on parameters of the anterior segment of the eye and tear film function tests in patients with multiple sclerosis (MS).
Methods: Forty-eight eyes of 24 individuals who were started on systemic fingolimod treatment for relapsing-remitting MS were prospectively enrolled in this study. Patients underwent examinations immediately before initiation of systemic fingolimod treatment, and at the first and sixth months of treatment.

Purpose: To evaluate the effect of upper eyelid blepharoplasty with or without the removal of a strip of orbicularis oculi muscle on corneal topographic parameters, anterior segment parameters, intraocular pressure, and ocular biometry.
Method: This prospective study examined 428 eyes of 214 patients with dermatochalasis. Patients were divided into two groups randomly: those who underwent orbicularis oculi muscle excision (Group 1) during blepharoplasty and those who did not (Group 2).

Objectives: This study aimed to explore anatomical differences in the aqueous humor (AH) outflow pathway between male and female dogs using ultrasound biomicroscopy (UBM).
Animals Studied: Clinical data were collected from 30 eyes of 30 dogs (15 males: 10 right eyes, 5 left eyes; and 15 females: 7 right eyes, 8 left eyes) treated at the Veterinary Medical Teaching Hospital of Chungbuk National University, South Korea, between August 2018 and February 2024.
Procedure: The study conducted an in-depth UBM examination, specifically observing peripheral anterior chamber depth (ACD), geometric iridocorneal angle (ICA), and angle-opening distance (AOD) alongside measurements of ciliary cleft width (CCW), length (CCL), and area (CCA), and assessed the longitudinal fibers of ciliary muscle thickness (Lf-CMT) and the longitudinal and radial fibers of ciliary muscle thickness (LRf-CMT) for gender-based differences.
