Aim: To prove that antibiotic distribution by grassroots volunteer village health workers (WHWs) in Bhutan is an effective and efficient public health intervention for the prevention of post- traumatic corneal ulceration. Methods: 55 villages in two districts in Bhutan were selected for the study. A defined population of 10 139 individuals was followed prospectively for 18 months by 31WHWs who were trained to identify posttraumatic corneal abrasions with fluorescein dye and a blue torch and to administer 1% chloramphenicol ointment three times a day for 3 days to the eyes of individuals who fulfilled the eligibility criteria. Results: During the 18month period 135 individuals reported to WHWs with an ocular injury and 115 were found to have a corneal abrasion. All 115 were treated with 1% chloramphenicol ointment three times a day for 3 days and all healed without sequelae. Conclusions: Corneal ulcers that occur following traumatic corneal abrasions can be effectively prevented, even in the setting of isolated rural conditions such as those that exist in villages in Bhutan, by using relatively simple preventative measures that local WHWs can easily be taught to employ.
