Interventions for trachoma trichiasis
No trials show interventions for trichiasis prevent blindness. Certain interventions have been shown to be more effective at eliminating trichiasis.
Repeated infections cause scarring of the conjunctiva of the upper eyelid, which causes the eyelid to turn in (entropion) so that the eyelashes touch the cornea at the front of the eye. This is known as trachoma trichiasis. Every movement of the eye or eyelids causes trauma to the corneal surface so that it eventually turns opaque and the person becomes blind. This review assesses the effects of different interventions for trachoma trichiasis (both surgical and non-surgical) to identify the most effective means of eliminating trichiasis and the most acceptable way of delivering these.
