Trachoma, Childhood Mortality, and Corneal Ulcer Treatment and Prevention

About

Dr. Lietman investigates which community treatment strategies are most effective in eliminating trachoma. With Dr. Porco, he builds mathematical models to determine who within communities needs to be targeted, how often communities need treatment, and whether the World Health Organization's antibiotic program risks generating drug resistance. With Dr. Keenan, he conducts clinical trials evaluating the long-term effects of mass antibiotic treatment to determine whether infectious trachoma can truly be eliminated through repeat community treatment. Together with Drs. Acharya, Keenan, and Rose-Nussbaumer, he leads corneal ulcer treatment and prevention trials in collaboration with the Aravind Eye Care System, Seva, and Bharatpur Eye Hospital in South India and Nepal.
