Patients were randomly assigned initially to receive single dose of oral azithromycin to subject or single dose of azithromycin to subject \& immediate family members or topical tetracycline ointment to subject groups.1 yr data suggested no difference in outcome between 2 azithromycin arms.These 2 groups were combined into 1 group in final analysis.

PRIMARY outcome

Timeframe: Primary outcome assessed at 2 weeks,1.5 months, 6 months and 12 months post-surgery

Population: Recurrence rates (expressed as person-years) in the tetracycline arm was compared with the 2 azithromycin arms combined (483+ 485= 968 participants)

Recurrence of trichiasis : Clinical assessment was done by looking for one or more eye lashes touching globe or evidence of epilation.

PRIMARY outcome

Timeframe: Primary outcome assessed at 2 weeks,1.5 months, 6 months and 12 months post-surgery

Recurrence of trichiasis :Clinical assessment for recurrence was done by looking for one or more eye lashes touching globe or evidence of epilation. If there was evidence of epilation or if one or more eye lashes were touching the globe, it was considered as recurrence of trichiasis.
