Trichiasis and disability in a trachoma-endemic area of Tanzania.

OBJECTIVE: To measure limitations in the daily activities of village life associated with having trichiasis for individuals with and without visual acuity loss. METHODS: Men and women 40 years and older in 6 randomly chosen rural villages in the Kongwa district of Tanzania had visual acuity measured and were examined by an ophthalmologist. Subjects indicated the degree of difficulty with daily activities of village life and whether the difficulty was related, in any way, to vision. Limitations were scored using an indicator of "any difficulty" and using a 4-point scale ranging from "no difficulty" to "unable to do." Scores of individuals with and without trichiasis were compared separately for men and women. RESULTS: Among men, trichiasis was associated with excess functional limitation only for those with visual acuity loss (adjusted difference in proportion of tasks [AD] compared with men with neither trichiasis nor visual impairment, 0.35; 95% confidence interval [CI], 0.23-0.47). For women, trichiasis alone was limiting (AD, 0.15; 95% CI, 0.08-0.22) similarly to visual acuity loss alone (AD, 0.09; 95% CI 0.06-0.13), and the combination led to greater limitations (AD, 0.32; 95% CI, 0.26-0.39). CONCLUSION: The burden of trichiasis is likely greater than previously estimated, especially in women for whom trichiasis alone was disabling.

Single-dose azithromycin prevents trichiasis recurrence following surgery: randomized trial in Ethiopia.

BACKGROUND: Trichiasis recurrence following surgery is a serious problem for trachoma programs. OBJECTIVE: To determine if postoperative treatment with azithromycin compared with topical tetracycline reduces recurrence up to 1 year, and if azithromycin treatment of household members provides additional benefit compared with treating only the surgical patient. DESIGN: A randomized, single-masked, clinical trial was conducted in Ethiopia. A total of 1452 patients with trichiasis were randomized 1:1:1 to the following 3 arms: single-dose (1 g) oral azithromycin alone, single-dose azithromycin for household members (20 mg/kg up to 1 g) plus the patient, or topical tetracycline (twice per day for 6 weeks). MAIN OUTCOME MEASURES: Trichiasis recurrence within 1 year following surgery. RESULTS: The combined azithromycin groups had significantly fewer recurrences, 6.9 of 100 person-years overall, compared with topical tetracycline, 10.3 of 100 person-years (P = .047). There was no additional reduction in the arm that also treated household members, 8.1 of 100 person-years, compared with treating the surgical patients alone, 5.8 of 100 person-years (P = .19). CONCLUSIONS: In trachoma-endemic areas, a single dose of azithromycin reduced postoperative trichiasis recurrence rates by one third compared with topical tetracycline. Application to Clinical Practice In countries where azithromycin is part of the Trachoma Control Program, patients with trachomatous trichiasis should be treated postoperatively to prevent recurrence.
