Because the light reflected by tissues varies with the degree of viability, spectacles were made from glass transmitting light of a certain wavelength to help distinguish viable from non-viable tissue. They were used in wound débridement in 300 injured patients. The results showed that the quality of débridement was improved as shown by better and quicker healing. They can also be used to predict flap viability in plastic surgery.

Introduction: Presbyopia, difficulty in seeing close-ups, affects a billion people globally. Mobile financial services (MFS) have been mandated since January 2021 for Bangladesh government social safety net payments, including old age allowance (OAA) and widow allowance (WA). We report the protocol for the Transforming Households with Refraction and Innovative Financial Technology randomised trial assessing the impact on the use of online banking of providing presbyopic safety net beneficiaries with reading glasses, and brief smartphone and mobile banking app training.

Background: Observational studies should not be used to infer causation as they are prone to confounding factors, selection bias, and reverse causality. Many observational studies of labor analgesia treated epidurals as an independent exposure and concluded that "epidurals" cause dystocia, despite multiple randomized controlled trials showing no effect. We highlight this problem using reductio ad absurdum.

Background: Traffic crashes are the leading cause of death globally for people aged 5-29 years, with 90% of mortality occurring in low- and middle-income countries (LMICs). The STABLE (Slashing Two-wheeled Accidents by Leveraging Eyecare) trial was designed to determine whether providing spectacles could reduce risk among young myopic motorcycle users in Vietnam.
Methods: This investigator-masked, stepped-wedge, cluster randomised naturalistic driving trial will recruit 625 students aged 18-23 years, driving ≥ 50 km/week, with ≥ 1-year driving experience and using motorcycles as their primary means of transport, in 25 clusters of 25 students in Ho Chi Minh City, Vietnam.

Purpose: This study evaluates differences in the visual field performance when wearing the Defocus Incorporated Multiple Segments (DIMS) spectacle lens compared to wearing a conventional single vision (SV) spectacle lens.
Methods: Twenty-one children aged 9-14 years with spherical equivalent refraction (SER) between -1.13D to -4.

Purpose: To characterize corneal and conjunctival abnormalities (CCAs) and their impact on visual acuity in a cohort of survivors from the Western African Ebola virus disease (EVD) outbreak.
Design: A post hoc analysis of 121 patients, who had previously undergone screening for the Ebola Virus Persistence in Ocular Tissues and Fluids study, was performed.
Methods: Patients underwent a comprehensive ophthalmic exam at the Lowell and Ruth Gess Eye Hospital in Freetown, Sierra Leone.
