Some examples of work include helping to develop new treatments for diseases, such as ivermectin for onchocerciasis (river blindness); showing how packaging can improve use of artemesinin-combination treatment (ACT) for malaria; demonstrating the effectiveness of bednets to prevent mosquito bites and malaria; and documenting how community-based ...
However, new research suggests a link between weight loss drugs and blindness (and other eye issues), leading some to refer to the issue as “Ozempic blindness.”
