Précis: Among subjects with glaucoma, wedge-shaped defects on optical coherence tomography angiography (OCTA) were associated with disc hemorrhages (DH), paracentral visual field (VF) defects, increased cup-to-disc ratio (CDR), and thinner retinal nerve fiber layer (RNFL).Purpose: To examine determinants of wedge defects on peripapillary OCTA in glaucoma. Materials and Methods:A total of 278 eyes of 186 subjects with mild to severe primary open-angle glaucoma underwent 6×6 spectraldomain OCTA imaging of the superficial peripapillary retina from 2016 to 2020 at an academic practice. Wedge defects were defined as focal microvasculature loss that extends outward from the optic nerve in an arcuate, wedge shape. Logistic regression models controlling for intereye correlation identified variables significantly associated with wedge defects. Eyes with profound microvasculature loss in both hemispheres were excluded. Candidate variables included: age, sex, race or ethnicity, diabetes, hypertension, follow-up duration, baseline untreated intraocular pressure, intraocular pressure at time of imaging, DH history, paracentral VF defects, CDR, central corneal thickness, spherical equivalent, VF mean deviation, RNFL thickness, and glaucoma stage.Results: Of 278 eyes, 126 (45.3%) had wedge defects in at least 1 hemisphere. In our multivariable logistic regression model, wedge defects were associated with DH history [odds ratio (

At the onset of the COVID-19 pandemic, many senior patients in the USC-Keck Family Medicine clinics were limited or lacking in telemedicine participation. Three factors contributed: lack of video-enabled devices, technological literacy, and/or absence of Wi-Fi connectivity. We addressed the first 2 of these factors. Via phone contact, 9 patients agreed to receive donated Android or Apple devices and to trial instruction manuals for use. Donated equipment and instructions were prepared and delivered in accordance with pandemic guidelines. Follow-up calls indicated that 4 participants were able to set up their devices and 3 of whom had connected with their providers. The remaining 5 participants had not set up their devices by the end of the follow-up period, had difficulty with device setup, accessing applications necessary for telemedicine, or had limited access to Wi-Fi. This project highlights some telemedicine barriers that senior patients may overcome with the additional support of care providers.
