Prcis: Self-determination theory (SDT) guided behavioral interventions are effective in improving several patient-centered metrics, including glaucoma-related distress. However, whether improvement in patient-centered metrics can drive an improvement in medication-taking behavior remains to be seen.

Objective: The 7-month Support, Educate, Empower (SEE) personalized glaucoma coaching program was previously shown to improve glaucoma medication adherence by 21 percent points.

Background: The concepts of the representation of visual field in primary visual cortex are based on studies of war wounds and correlations with brain imaging in small cohorts. Because of the difficulty of judging brain lesion extent and the small number of studied patients, there is lingering controversy as to whether the central 15° of visual field are mapped onto the posterior 25% of primary visual cortex or onto a larger area. To improve the delineation of MRI lesion extent, we have studied only patients with posterior cerebral artery (PCA) ischemic strokes.

Background: The representation of the visual field in visual cortex was established over a century ago by correlating perimetric defects with the estimated location of war wounds. The availability of high-definition MRI offers the possibility of more precise correlation.

Methods: Homonymous hemianopias disclosed on automated visual fields (HVFs) were drawn from an electronic medical record search from 2009 to 2020 at the Michigan Medicine, a tertiary care academic medical center.

Background: Perimetry is widely used in the localization of retrochiasmal visual pathway lesions. Although macular sparing, homonymous paracentral scotomas, and quadrantanopias are regarded as features of posterior retrochiasmal visual pathway lesions, incongruous hemianopia is regarded as a hallmark of anterior lesions. Recent studies have questioned the specificity of these defect patterns.

Purpose: To assess the efficacy of the Support, Educate, Empower (SEE) glaucoma coaching program on medication adherence among poorly adherent patients with glaucoma for 12 months after cessation of the intervention.

Design: Uncontrolled intervention study with a pre-post design.

Participants: The SEE cohort was recruited from the University of Michigan and included patients with glaucoma aged ≥ 40 years, taking ≥ 1 medication, who self-reported poor adherence.

Background: Lean methodology helps maximize value by reducing waste, first by defining what value and waste are in a system. In ophthalmology clinics, value is determined by the number of patients flowing through the clinic for a given time. We aimed to increase value using a lean-methodology guided policy change, then assessed its impact on clinic flow using an automated radiofrequency identification (RFID) based real-time locating system (RTLS).

Purpose: To assess the accuracy of 5 subjective self-assessment tools (3 adherence measures and 2 psychometric scales) and pharmacy refill data in predicting objective electronically monitored nonadherence.

Design: Prospective cohort study.

Participants: Glaucoma patients (> 40 years old, >1 medication with poor self-reported adherence) were recruited from University of Michigan Kellogg Eye Center for a study assessing the impact of a personalized glaucoma coaching program on medication adherence.

Purpose: To assess the initial utilization, safety, and patient experience with tele-ophthalmology during the COVID-19 pandemic.

Design: Cross-sectional study.

Methods: We conducted a telephone survey and interview of a random sample of patients who received different modalities of care (in-person, telephone, videocall, or visits deferred) during Michigan's shelter-in-place order beginning March 23, 2020.

Significance: Uncorrected refractive error is the main cause of visual impairment globally. Understanding barriers and facilitators underserved individuals face in obtaining eyeglasses will help address high rates of uncorrected refractive error.

Purpose: The purpose of this study was to understand the barriers and facilitators to obtaining eyeglasses among low-income patients in Michigan.

Precis: Higher levels of near vision-related quality of life (VRQoL) were associated with higher adherence to glaucoma medications after adjusting for important confounding variables among participants in the Support, Educate, Empower (SEE) personalized glaucoma coaching pilot study.

Purpose: To investigate the association between VRQoL and glaucoma medication adherence.

Materials And Methods: Subjects were recruited for the SEE program, a prospective noncontrolled cohort study examining the impact of a personalized coaching program on glaucoma medication adherence.

Prcis: Community-engaged research (CER) enables researchers to identify community-specific barriers and facilitators to program implementation. Broadly applicable barriers to glaucoma care, such as Cost, Transportation, and Trust, and community-specific barriers, such as Language and Convenience/Access, were identified.

Purpose: The aim was to identify the facilitators and barriers to implementing glaucoma screening programs in 2 community clinics.

Ophthalmic clinicians report low confidence in telemedicine-based eye care delivery, but it may have changed given its rapid expansion during the coronavirus 2019 (COVID-19) pandemic. The purpose of this study was to determine clinician confidence in telemedicine-based eye care services during COVID-19. An electronic survey was sent to clinicians at University of Michigan Kellogg Eye Center (April 17, 2020-May 6, 2020) when nonemergent in-person visits and procedures were restricted.

: Data on glaucoma treatment barriers in South India is limited; improved knowledge of barriers could advance disease self-management. We aimed to understand glaucoma treatment barriers in South India.: Glaucoma patients ≥18 taking ≥1 medication at the Aravind Eye Hospital were screened with a validated medication adherence tool.

To address the growing need for new antimicrobial agents, we explored whether inhibition of bacterial signaling machinery could inhibit bacterial growth. Because bacteria rely on two-component signaling systems to respond to environmental changes, and because these systems are both highly conserved and mediated by histidine kinases, inhibiting histidine kinases may provide broad spectrum antimicrobial activity. The histidine kinase ATP binding domain is conserved with the ATPase domain of eukaryotic Hsp90 molecular chaperones.
