Background: Lower density of carotenoids lutein and zeaxanthin (L/Z) in the macula (i.e., macular pigment) has been linked to greater risk for age-related eye disease.

Purpose: This study aims to investigate generalizability of deep learning (DL) models trained on commonly used public fundus images to an instance of real-world data (RWD) for glaucoma diagnosis.

Methods: We used Illinois Eye and Ear Infirmary fundus data set as an instance of RWD in addition to six publicly available fundus data sets. We compared the performance of DL-trained models on public data and RWD for glaucoma classification and optic disc (OD) segmentation tasks.

Objective: To investigate associations between baseline macular pigment optical density (MPOD) and retinal layer thicknesses in eyes with and without manifest primary open-angle glaucoma (POAG) in the Carotenoids in Age-Related Eye Disease Study 2 (CAREDS2).

Methods And Analysis: MPOD was measured at CAREDS baseline (2001-2004) via heterochromatic flicker photometry (0.5° from foveal centre).

Purpose: To determine if glaucoma medications are associated with pregnancy and/or postnatal complications.

Methods: Multicenter descriptive survey. Subjects were female patients 18-45 years who were previously pregnant with a diagnosis of glaucoma or ocular hypertension prior to pregnancy.

Purpose: Topical netarsudil 0.02% may reduce intraocular pressure (IOP) by decreasing episcleral venous pressure (EVP), which carries theoretical utility for glaucoma associated with elevated EVP. A role for netarsudil in patients with elevated EVP is evaluated in a pilot investigation using a cohort of individuals with Sturge-Weber syndrome (SWS).

Purpose: To investigate the relationships between optic nerve cupping and total and regional brain volumes.

Design: Secondary analysis of randomized clinical trial data.

Methods: Women 65 to 79 years of age without glaucoma with cup-to-disc ratio (CDR) measurements from the Women's Health Initiative (WHI) Sight Examination study and magnetic resonance imaging (MRI)-based total and regional brain volumes from the WHI Memory Study MRI-1 were included.

Purpose: We tested whether dietary modification (DM) altered the risk for incident primary open-angle glaucoma (POAG).

Design: Secondary analysis of a randomized intervention trial.

Participants: We linked Medicare claims data to 45 203 women in the Women's Health Initiative Dietary Modification Trial, of which 23 776 participants were enrolled in fee-for-service Medicare Part B and had physician claims.

Article Synopsis
  • The study aimed to see if a genetic risk score (GRS) for cup-to-disc ratio (CDR) affects the relationship between large CDR and cognitive function in women.
  • It's a retrospective analysis using data from the Women's Health Initiative, focusing on 1,196 White women aged about 70.
  • The findings showed that women with large CDR had significantly lower cognitive function regardless of their genetic risk score, indicating a clear association between large CDR and cognitive decline.

The authors reviewed perioperative ocular complications and implications of ocular diseases during nonocular surgeries. Exposure keratopathy, the most common perioperative eye injury, is preventable. Ischemic optic neuropathy, the leading cause of perioperative blindness, has well-defined risk factors.

Introduction: To evaluate the refractive outcome of combined cataract extraction and glaucoma drainage device (GDD) surgery.

Methods: Patients who had undergone combined phacoemulsification with GDD surgery [Baerveldt, Abbott Medical, Abbott Park (IL) or Ahmed valve, New World Medical, Rancho Cucamonga (CA)] between June 2009 and August 2017 were included in the study. The main outcome measure evaluated was whether or not spherical equivalent (SE) between ± 1D from target refraction was achieved at 3-6 months postoperatively.

Background: In response to the COVID-19 pandemic, a web-based tele-triage system was created to prioritize in-person clinic visits and ensure safety at the University of Illinois at Chicago Department of Ophthalmology and Visual Sciences during a statewide shelter-in-place order. The aim of this study is to evaluate the impact of the tele-triage system on urgent visit volume and explore the characteristics of acute visit requests at a tertiary referral eye center.

Methods: This retrospective study analyzed acute visit requests between April 6, 2020 and June 6, 2020.

Purpose: To evaluate medication and follow-up adherence in incarcerated patients examined at an academic glaucoma clinic, in comparison to nonincarcerated controls.

Methods: Retrospective, case-control study. Consecutive prisoners presenting for initial visits in the Glaucoma Clinic at the Illinois Eye and Ear Infirmary between December 2015 and December 2017 were included in the study.

Glaucoma-related ocular surface disease (G-OSD) is a significant, yet often underdiagnosed, ocular co-morbidity affecting 40% to 59% of glaucoma patients worldwide. Although the use of topical glaucoma medications represents a proven strategy to control the untoward effects of high intraocular pressure, this treatment can profoundly disrupt the homeostasis of the tear film. The cumulative effect of medications, preservatives, and excipients alter underlying cellular structures which results in tear film abnormalities and instability of the ocular surface.

Primary open-angle glaucoma (POAG) is an age-dependent, intraocular pressure (IOP)-related degeneration of the retinal ganglion cells (RGC). At present, IOP is the only modifiable factor that has been identified to prevent glaucomatous vision loss. Though the pathogenesis of glaucomatous optic neuropathy is still not well understood, increasing evidence suggests oxidative stress may contribute to the induction and progression of glaucoma.

Importance: Glaucoma care for prison inmates is underrepresented in the literature even though managing the treatment of such patients may provide unique challenges.

Objectives: To evaluate the glaucoma profile of prison inmates treated at an academic ophthalmology center and to report on the medical and surgical management and follow-up metrics.

Design, Setting, And Participants: This retrospective cohort study assessed data from 82 incarcerated patients treated at the glaucoma clinic, an academic referral center at the University of Illinois at Chicago, between January 2013 and December 2017.

Precis: A meta-analysis shows that second glaucoma drainage implantation can be effective after a failed drainage implant. There is a need for continued glaucoma medications and the risk of corneal decompensation.

Purpose: Studies on second glaucoma drainage implantation are small and exploratory.

Patients with a keratoprosthesis often develop complications including glaucoma, requiring glaucoma drainage devices. In most of these patients, glaucoma drainage devices have been shown to be safe and effective. However, occasionally, a glaucoma drainage device in the setting of a keratoprosthesis can lead to conjunctival erosion with mechanical trauma.

Purpose: To determine if a larger cup-to-disc ratio is associated with poor cognitive function in postmenopausal women without glaucoma or ocular hypertension.

Methods: We used data from the Women's Health Initiative (WHI) hormone trial, originally designed to test effects of hormone therapy (HT) on various health outcomes. Large cup-to-disc ratio was defined as greater than 0.
