Visual function, digital behavior and the vision performance index.

Historically, visual acuity has been the benchmark for visual function. It is used to measure therapeutic outcomes for vision-related services, products and interventions. Quantitative measurement of suboptimal visual acuity can potentially be corrected optically with proper refraction in some cases, but in many cases of reduced vision there is something else more serious that can potentially impact other aspects of visual function such as contrast sensitivity, color discrimination, peripheral field of view and higher-order visual processing.

Trabectome outcomes across the spectrum of glaucoma disease severity.

Purpose: To compare the efficacy of ab-interno trabeculotomy with Trabectome® in mild glaucoma versus moderate/severe glaucoma along the spectrum of glaucoma disease severity.

Methods: Subjects with at least 12 months follow-up were separated into two groups based on glaucoma severity. Severity was determined based on optic nerve cup-to-disc ratio and/or automated visual field data, with cup-to-disc ratio < 0.

Acute Onset Ocular Hypotony after Coronary Artery Bypass Surgery.

Importance: The purpose of this case report is to evaluate risk factors associated with post-coronary artery bypass graft (CABG) ocular hypotony compared to post-CABG ischemic optic neuropathy.

Observations: The patient described here is a single case at the University of California, Irvine Medical Center, from July 2016. This case demonstrates the rare incidence of acute post-CABG ocular hypotony and vision loss in a patient with prior history of optic atrophy.
