Cataract surgical outcomes, visual function and quality of life in four rural districts in Vietnam.

Background: To evaluate cataract surgical outcomes in four rural districts of Ha Tinh Province, Vietnam.

Design: Cross-sectional study.

Participants: Post-cataract surgery patients sampled randomly from facilities in four rural districts of Ha Tinh Province >3 months after surgery.

The determinants of trichiasis recurrence differ at one and two years following lid surgery in Vietnam: A community-based intervention study.

Aim: To compare determinants for recurrence of trichiasis at one and two years following lid surgery in Vietnam.

Study Design: Community-based intervention study.

Methods: This study was carried out between 2000 and 2003 in four trachoma-endemic districts of Vietnam.

Impact of annual targeted treatment on infectious trachoma and susceptibility to reinfection.

Context: The World Health Organization developed the SAFE strategy (Surgery for trichiasis; Antibiotics for Chlamydia trachomatis infection; Facial cleanliness; and Environmental improvement) to eliminate blinding trachoma globally by the year 2020. Despite a number of studies using various intervals of treatment for different prevalence rates, there has been a lack of sufficient follow-up beyond the final treatment point to determine rates of recurrence of disease and infection and the risk factors that may contribute to each.

Objective: To evaluate the impact of 2 annual targeted azithromycin treatments on active trachoma and C trachomatis infection rates over 3 years in Vietnam.
