Contrast sensitivity (CS) testing is an important measure of visual function reflecting variations in everyday visual experience in different conditions and helps to identify more subtle vision loss. However, it is only infrequently used. To make this more accessible, this study developed and validated a smartphone-based CS test.
This study suggests that the effect of infection on scarring progression is mediated through papillary inflammation, and that other factors contributing to the development of inflammation, in addition to C. trachomatis infection, may be important in driving conjunctival scarring progression in children.
This study tested the hypothesis that an automated algorithm could classify eyelid photographs better than chance.
Determining whether a follicle has a diameter ≥0.5mm is difficult using magnifying loupes alone. This article explored an ultra-low-cost solution that has been developed: a follicle size guide that takes the form of a durable printed adhesive sticker which can be fixed to graders' thumb nails for direct size comparison.
This study demonstrates the extent of genomic diversity within a naturally circulating population of ocular Ct and is the first to describe novel genomic associations with disease severity. These findings direct investigation of host-pathogen interactions that may be important in ocular Ct pathogenesis and disease transmission.

The study was conducted in three adjacent trachoma endemic villages in Kilimanjaro and Arusha regions, Northern Tanzania.
This journal article evaluates a new trachoma scarring ranking system with potential use in clinical research.
A synopsis of Light out of deep darkness, the biography of Arthur MacCallan, an ophthalmologist who undertook pioneering work on trachoma in Egypt between 1903 and 1923.
