Trachomatous trichiasis surgery improves quality of life regardless of vision outcomes

Trachomatous trichiasis (TT, inturning of the eyelashes to touch the eye following longterm infection with Chlamydia trachomatis) affects over seven million people world-wide. Corrective eyelid surgery is the recommended treatment for TT. A study published in PLOS Neglected Tropical Diseases reports that surgery substantially increases the quality of life (QoL) for affected people, even when their vision is not improved.

TT can cause vision loss over time and is the major cause of infectious blindness in the world. Besides compromising eye health, TT also causes social withdrawal and exclusion, as well as inability to work and earn an income. WHO has developed and validated several tools for measuring health-related quality-of-life. These include a questionnaire designed to measure vision-related quality of life (VRQoL), and one which measures general health-related quality of life (HRQoL).
