Taming Trachomatous Trichiasis: Impact of Community-Based Lid Surgical Services on the Burden of Trichiasis in Districts of Kebbi State, Nigeria

An emergency trachoma control programme was established in Kebbi state, Nigeria since 2003 in which ophthalmic nurses (ONs) were trained to provide community-based lid surgical services to persons with trachomatous trichiasis in some districts of the state. This paper aim to present the impact of the lid surgical services on trachomatous trichiasis in non-programme districts. It will specifically present the lid surgical coverage in districts that had no control programme.

Persons 15 years and above residing in the randomly selected households in the paticipating districts.

A population based cross-sectional survey was conducted in 15 local government areas (LGAs) between November and December 2011 to provide a baseline data for trachoma control. Eye examination for trichiasis was based on WHO standardized grading scheme for trachoma.Data was collected on selected subjects to determine those persons with TT and those who had previous TT lid surgery.Trichiasis surgical coverage was calculated based on the proportion of persons that had TT surgery out of those that should have had the TT surgery.

Results and Conclusion
The targeted sample coverage achieved ranged between 69% and 100% across the LGAs. The prevalence of TT in adults 15 years and older ranged from 0.03% in Aliero and Zuru LGAs to 0.3% in Danko-Wasagu LGA. There was no person seen with previous TT surgery in 5 LGAs. Generally more men had been operated for TT except in 2 LGAs where more women have had previous lid surgery.
The trichiasis surgical coverage (TSC) ranged between 0% in 5 LGAs to 100% in 1 LGA. The coverage was higher among the male subjects.
The proportion of persons with TT is generally low. However the upper confidence level magnitude indicates there is still a need to do more TT lid surgeries in all the LGAs before TT can be considered eliminated in the LGAs.
