In Tanzania, a leading eye specialist is making significant strides in the fight against trachoma, a major public health concern in the country. Dr. Margaret Mumbua Muthoka, based in Chalinze District, has been providing essential eye‑care services since 2017, when she was selected as the district coordinator of eye health services by Sightsavers, a global organization working to prevent avoidable blindness.
Trachoma, caused by the bacterium *Chlamydia trachomatis*, is the leading infectious cause of blindness worldwide and disproportionately affects poor, rural communities with limited access to clean water and sanitation. Repeated infections can scar the inner upper eyelid, causing eyelashes to turn inward and scratch the eyeball. If left untreated, this condition—trachomatous trichiasis (TT)—leads to irreversible blindness. Early diagnosis and surgery can prevent this outcome, making TT surgeons like Muthoka crucial in the battle against blindness.
Muthoka’s journey into eye health was driven by circumstance. She was already a medical practitioner when the councils of Chalinze and Bagamoyo were divided in 2016, leaving Bagamoyo without an eye specialist. She pursued further training, completing a three‑month eye‑health course at the Mvumi Institute for Optometric Assistants and later training as a TT surgeon. To date, she has performed over 200 surgeries.
Despite challenges such as fear, lack of information, and long distances to surgical camps, Muthoka has witnessed significant improvements in her patients’ lives after surgery, enabling them to resume daily activities and earn a living. Sightsavers supports these outcomes with several post‑operative follow‑ups: a one‑day check, a 7‑14‑day visit, and a three‑to‑six‑month review to monitor for recurrences or eye granuloma.
Beyond surgery, Muthoka plays a vital role in community education, training caretakers and case finders to raise awareness about trachoma and its treatment. The awareness campaign is changing perceptions; community members now call to ask when they can be tested or treated.
The World Health Organization aims to eliminate trachoma as a public health issue by 2030. Muthoka emphasizes that financial support is essential to reach people in rural areas and achieve this goal. Eliminating trachoma requires a multi‑faceted approach, including mass drug distribution, the SAFE strategy (Surgery, Antibiotics, Facial cleanliness, and Environmental improvements), and improved water, sanitation, and hygiene (WASH) facilities. With continued effort and funding, trachoma can be eradicated as a public health threat, and Muthoka’s work represents a significant step toward that objective.
