Article Synopsis
  • The study aimed to determine if the structure and biomechanics of neural tissue can predict functional loss in glaucoma and to assess the role of biomechanics in improving prediction accuracy.
  • Researchers gathered data from 238 glaucoma patients over 50 years old, using advanced imaging techniques to analyze the optic nerve head under different pressure conditions.
  • Results showed that incorporating biomechanical data significantly improved prediction performance (F1-score: 0.76) compared to using only structural information (F1-score: 0.71), highlighting the importance of biomechanics in assessing glaucoma severity.*

Article Synopsis
  • The study compared changes in macular curvature after a spike in intraocular pressure (IOP) across various types of myopia, using 328 eyes from 184 participants.
  • Researchers utilized optical coherence tomography (OCT) to assess macular changes at baseline and during acute IOP elevation, specifically measuring the curvature of the sclera-choroid interface.
  • Results showed that individuals with pathological myopia and those with glaucoma exhibited significantly more curvature change compared to those with high myopia or emmetropic controls, suggesting increased sensitivity to IOP elevation in these groups.

Article Synopsis
  • - The study aims to evaluate the reliability and consistency of a new hyperparallel optical coherence tomography (HP-OCT) system for assessing angle closure in the eye, comparing it with the existing swept-source OCT (SS-OCT) and gonioscopy methods.
  • - Conducted on phakic subjects over 40 years old with no significant eye conditions, the research found that HP-OCT had excellent reproducibility and good agreement with both SS-OCT and gonioscopy for detecting angle closure.
  • - The findings suggest that HP-OCT not only excels in angle closure assessment but also uniquely visualizes important eye structures, potentially enhancing clinical research on fluid drainage in the eye.

(1) Background: Fulminant myocarditis (FM) could result in hemodynamic derangement and fatal arrhythmia. Veno-arterial extracorporeal membrane oxygenation (V-A ECMO) is used to maintain organ perfusion in FM patients complicating cardiogenic shock. The present study aims to assess the static and dynamic factors in association with mortality in FM patients on V-A ECMO (2) Methods: Twenty-eight patients were enrolled between 2013 to 2019 for analysis (3) Results: In-hospital survival rate was 78.

Purpose: To describe the outcomes of surgical bleb revisions from a tertiary glaucoma service in Singapore.

Methods: One hundred and thirty-one eyes of 129 patients who underwent surgical bleb revisions at the Singapore National Eye Centre between 2007 and 2014 were included in the study. The indications for bleb revision were: bleb-related infection (BRI), early and late bleb leak, early and late overfiltration, and bleb dysesthesia.

We describe 3 cases of unilateral congenital ectropion uveae associated with ptosis and glaucoma in a syndrome with no systemic associations. Early detection of glaucoma and timely surgical intervention is required to preserve productive vision in such patients. In our case series, trabeculectomy with mitomycin C was effective in controlling glaucoma progression over a follow-up period of 5-15 years.

Purpose: The purpose of this study was to investigate whether the addition of primary angle closure glaucoma (PACG)-associated genetic loci allows improved detection of PACG, compared to anterior segment parameters measured by imaging.

Design: Case-control study.

Methods: Genotype data of the 8 PACG single-nucleotide polymorphisms (SNPs) (rs11024102 at PLEKHA7, rs3753841 at COL11A1, rs1015213 located between PCMTD1 and ST18 on Chromosome 8q, rs3816415 at EPDR1, rs1258267 at CHAT, rs736893 at GLIS3, rs7494379 at FERMT2, and rs3739821 mapping in between DPM2 and FAM102A) were available.

Childhood glaucoma poses a diagnostic and therapeutic challenge to ophthalmologists. Difficulty in examination and limitations on ability to perform structural and functional testing of optic nerve make diagnosis and verification of glaucoma control difficult in children. It is well known that an excessive loss of hyperopia is a useful sign in alerting the examining ophthalmologist to the possible diagnosis of glaucoma.

Article Synopsis
  • Primary angle closure glaucoma (PACG) is a key cause of blindness, prompting a large-scale study involving over 10,000 PACG patients and nearly 30,000 controls across multiple continents.
  • The study identified five new genetic loci associated with PACG risk, each with significant statistical results (e.g., EPDR1 with an odds ratio of 1.24 and a P-value of 5.94 × 10(-15)).
  • Additionally, three previously known genetic loci were confirmed, enhancing the understanding of the genetic factors underlying PACG.

Childhood glaucoma is known to be one of the most challenging conditions to manage. Surgical management is more complicated than in adults because of differences in anatomy from adults along with variations in anatomy caused by congenital and developmental anomalies, wide-ranging pathogenetic mechanisms, a more aggressive healing response, and a less predictable postoperative course. Challenges in postoperative examination and management in less cooperative children and the longer life expectancies preempting the need for future surgeries and reinterventions are also contributing factors.

Glaucoma is a chronic progressive optic neuropathy that is characterized by optic nerve changes and visual field loss. Elevated intraocular pressure (IOP) is the main modifiable risk factor. Chronic instillation of daily eyedrops to lower IOP is the primary treatment of choice, although it requires patient adherence and correct performance.
