Use of an inexpensive magnifier with light source in the diagnosis of trichiasis among community-based case finders in Nigeria


The purpose of this study undertaken in 2016 was to determine how the use of the “Wilson” an inexpensive hand-held magnifier with light source aids trained case finders in the diagnosis of people with trichiasis. The result concluded that case finders that used the Wilson were 4.57 times (95% CI 2.46-8.47) more likely to have patients presenting confirmed as trichiasis compared to those not using the Wilson. Case finders that used the Wilson felt the instrument was easy to use, enlarged the eyelashes and made diagnoses of trichiasis easier.
