Navigating postoperative complications: Uveitis-glaucoma-hyphema syndrome after Ahmed glaucoma valve implantation.

Altwijri and Alsirhy reported a case of uveitis-glaucoma-hyphema syndrome after an Ahmed glaucoma valve implantation surgery in an advanced primary open-angle glaucoma patient, being the first ever recorded of its kind. The author describes the position of the tube as the origin of the anterior chamber inflammation and hyphema, which resolved shortly after shortening and relocating it. This publication emphasizes the importance of precise implant positioning and close-up patient follow-up after glaucoma filtration surgery as an important standard for healthcare providers.

Phenotypic expressions of the optic disc in primary open-angle glaucoma.

Background: Which phenotypes are we able to recognize in the optic nerve of patients with primary open angle glaucoma?

Methods: Retrospective interventional case series. 885 eyes from 885 patients at an outpatient tertiary care centre who met specified criteria for POAG were included. Disc photographs were classified by three glaucoma specialists into the following phenotypes according to their predominant characteristics: (1) concentric rim thinning, (2) focal rim thinning, (3) acquired pit of the optic nerve (APON), (4) tilted, (5) extensive peripapillary atrophy (PPA), and (6) broad rim thinning.

The Success Rate of Glaucoma Drainage Device Revision.

Prcis: We report the survival of surgical revision to glaucoma drainage devices for several indications in a large cohort of patients, with an overall success rate of 45% at 36 months.

Purpose: To evaluate the outcomes of surgical revision for complications of glaucoma drainage devices.

Methods: Three hundred thirty-five eyes of 318 patients who underwent tube revision or removal at University of California Los Angeles (UCLA) Jules Stein Eye Institute between 1997 and 2019 were included.

Long-Term Visual Field Outcomes After Ahmed Glaucoma Valve Implantation.

Purpose: To measure visual field (VF) rates of change after Ahmed Glaucoma Valve (AGV) implantation and to investigate risk factors for progression.

Design: Retrospective, clinical cohort study.

Methods: Patients who underwent AGV implantation with at least 4 eligible postoperative VFs and 2 years of follow-up were included.

DDLSNet: A Novel Deep Learning-Based System for Grading Funduscopic Images for Glaucomatous Damage.

Purpose: To report an image analysis pipeline, DDLSNet, consisting of a rim segmentation (RimNet) branch and a disc size classification (DiscNet) branch to automate estimation of the disc damage likelihood scale (DDLS).

Design: Retrospective observational.

Participants: RimNet and DiscNet were developed with 1208 and 11 536 optic disc photographs (ODPs), respectively.

RimNet: A Deep Neural Network Pipeline for Automated Identification of the Optic Disc Rim.

Purpose: Accurate neural rim measurement based on optic disc imaging is important to glaucoma severity grading and often performed by trained glaucoma specialists. We aim to improve upon existing automated tools by building a fully automated system (RimNet) for direct rim identification in glaucomatous eyes and measurement of the minimum rim-to-disc ratio (mRDR) in intact rims, the angle of absent rim width (ARW) in incomplete rims, and the rim-to-disc-area ratio (RDAR) with the goal of optic disc damage grading.

Design: Retrospective cross sectional study.

A Metascore of Multiple Imaging Methods to Measure Long-Term Glaucoma Structural Progression.

Purpose: To develop a structural metascore (SMS) that combines measurements from different devices and expresses them on a single scale to facilitate their long-term analysis.

Methods: Three structural measurements (Heidelberg Retina Tomograph II [HRT] rim area, HD-Cirrus optical coherence tomography [OCT] average retinal nerve fiber layer [RNFL] thickness, Spectralis OCT RNFL global thickness) were normalized on a scale of 0 to 100 and converted to a reference value. The resultant metascores were plotted against time.

Structural-Functional Glaucoma Progression Trajectory in 2-Dimensional Space.

Prcis: We describe a method that provides rapid visualization of glaucomatous change in a 2-dimensional (2D) structural and functional (S/F) space.

Purpose: To describe a method to visualize glaucomatous change in a 2D S/F space.

Design: This was a retrospective longitudinal observational study.

The Trajectory of Glaucoma Progression in 2-Dimensional Structural-Functional Space.

Purpose: To present a method that allows visualization of functional and structural change in 2-dimensional space.

Design: Retrospective, longitudinal, observational study.

Participants: Patients from the Stein Eye Institute, UCLA from 1993 through 2017.
