Three-Year Outcomes of Pars Plana Ahmed and Baerveldt Glaucoma Implantations for Neovascular Glaucoma in Japanese Eyes
This study examined 41 eyes of 39 patients who underwent tube shunt implantation through the pars plana with the Baerveldt glaucoma implant (BGI group, 26 eyes) or Ahmed glaucoma valve (AGV group, 15 eyes) for NVG and who were followed up for over 3 years at Osaka Medical College between January 2009 and April 2016. Outcome measures were intraocular pressure (IOP, mm Hg) at presurgery and at 6 months and 1, 2, and 3 years postoperative. Postoperative failure was defined as an IOP of>21 mm Hg or

Association Between Dietary Salt Intake and Open Angle Glaucoma in the Thessaloniki Eye Study
Précis:
In the Thessaloniki Eye Study (TES) incidence phase population, frequent dietary salt intake was potentially associated with increased risk of open angle glaucoma in antihypertensive users.
Purpose:
The aim was to examine the association between dietary salt intake and glaucoma by antihypertensive use in the TES population.
Materials and Methods:
The study population included TES incidence phase participants. Dietary salt intake frequency was assessed by self-report. Outcomes included prevalence of any open angle glaucoma (OAG), primary open angle glaucoma (POAG), and pseudoexfoliation (PEX). Cov...

Association of Epiretinal Membrane With Pseudoexfoliation Glaucoma and Long-term Factors Affecting Visual Function
Conclusions:
ERM tended to deteriorate more in PXS eyes with than without glaucoma. Incremental change in CMT induced by ERM deterioration affected longitudinal visual function in PXG eyes.

Patterns of Visual Field Loss in Early, Moderate, and Severe Stages of Open Angle Glaucoma
Précis:
Even in the early stages of glaucomatous visual field defects (VFDs), 49% of the defects occurred in both hemifields and 28% involved the central 5 degrees of the visual field (VF), which may have prognostic values.
Purpose:
The aim was to determine the patterns of glaucomatous VFDs in early, moderate and severe stages of primary open angle glaucoma, using the Glaucoma Staging Application.
Methods:
According to the Modified University of Sao Paulo Glaucoma Visual Field Staging System Classification, patients with early, moderate and advanced VFDs were selected by the Glaucoma Staging Application ...

An Objective and Easy-to-Use Glaucoma Functional Severity Staging System Based on Artificial Intelligence
Conclusions:
We discovered that 4 severity levels based on MD thresholds of −2.2, −8.0, and −17.3 dB, provides the optimal number of severity stages based on unsupervised and supervised machine learning. This glaucoma staging system is unbiased, objective, easy-to-use, and consistent, which makes it highly suitable for use in glaucoma research and for day-to-day clinical practice.

Outcomes of Prolene Gonioscopy Assisted Transluminal Trabeculotomy in Primary Open Angle Glaucoma and Pseudoexfoliation Glaucoma: A Comparative Study
Précis:
Gonioscopy-assisted transluminal trabeculotomy (GATT) provides greater intraocular pressure (IOP) reduction in pseudoexfoliative glaucoma (PXG) than in primary open angle glaucoma (POAG) in the first year of surgery; however, the difference between groups equalizes in the long term.
Purpose:
To compare outcomes of GATT in eyes with POAG and PXG.
Methods:
Single-center, retrospective, comparative case-series. A total of 202 eyes (91 eyes of POAG; 111 eyes of PXG) were included. GATT was performed as a standalone procedure or in combination with cataract extraction. Outcome measures were change in ...

United States Medicare Reimbursement Trends for Glaucoma Procedures: 2000–2020
Conclusions:
The US Medicare reimbursement for glaucoma procedures in the United States showed a significant decline between 2000 and 2020. These findings may be relevant to understanding changing practice patterns for glaucoma care.

Effects of Exercise on Optic Nerve and Macular Perfusion in Glaucoma and Normal Subjects
Précis:
Using optical coherence tomography angiography, we found an increase in the blood flow in regional macular without significant changes in the optic disk in patients with glaucoma after a moderate exercise regime.
Purpose:
To investigate the effect of moderate exercise on optic nerve and macular perfusion in glaucoma patients.
Methods:
Overall, 25 eyes of 25 patients with primary open angle glaucoma and 22 eyes of 22 normal subjects were included in the glaucoma and control groups, respectively. Foveal avascular zone parameters, whole and regional vessel density (VD) in the superficial layer of ma...

Systemic Barriers in Receiving Electronically Prescribed Glaucoma Medications
Conclusions:
Approximately a third of electronically prescribed glaucoma medications were not received by patients within a month of refill request due to the need for prior authorization, insurance coverage, and pharmacy availability. A mechanism to alert providers and to address these barriers to medication access may minimize treatment interruption and disease progression.

Use of Telepresence Robots in Glaucoma Patient Education
Précis:
Telepresence robots (TR) present the versatility to effectively provide remote educational sessions for patients affected by glaucoma to improve disease knowledge. Given COVID-19’s effect on clinical practice, TR can maintain social distancing when educating patients.
Purpose:
TR are devices that allow remote users to have a mobile presence anywhere. We compared the effect of an education session given by an in-person educator versus a TR on glaucoma knowledge and identified factors that impact patient education.
Methods:
Eighty-five glaucoma patients were split into control, human, and TR grou...

A Scoping Review of Process Indicators for Measuring Quality of Care in Glaucoma
Conclusions:
There are notable variations among process QIs in glaucoma and significant heterogeneity in their descriptions in published studies. Although novel indicators can be inferred from guidelines and trials, they should be designed and standardized for better assessment of performance in health systems to improve their quality.

Central Visual Field Sensitivity With and Without Background Light Given to the Nontested Fellow Eye in Glaucoma Patients
This study showed the difference of monocular visual sensitivity between with and without background light given to the nontested fellow eyes in glaucoma patients. Monocular sensitivity measurements of the worse eyes with fellow eye’s background light conditions should carefully be considered when assessing the impact of functional impairment in glaucoma patients.
Purpose:
The purpose of this study was to investigate the difference between monocular sensitivities measured with and without background light given to the nontested fellow eye in glaucoma patients using a new perimeter named “imo.”
Methods:

Lessons Learned From 2 Large Community-based Glaucoma Screening Studies
Community-based screening programs have had limited success in preventing vision loss from glaucoma due to overall low prevalence of glaucoma, screening limitations, and barriers to follow-up appointments. This editorial highlights lessons learned from 2 large prospective trials: the Philadelphia Telemedicine Glaucoma Detection and Follow-up Study and the Screening To Prevent Glaucoma Study. While some lessons are specific to ophthalmology, many lessons are applicable to screening for asymptomatic diseases in underserved, vulnerable communities.
