To the Editor We read the article by Zhao et al with great interest.1 The authors provide a valuable contribution to addressing the lack of epidemiologic data on the cost and accessibility of glaucoma treatments worldwide. This is a major, often neglected issue, and the authors should be praised for tackling it.
Their study highlights the extent of global disparities in medical and surgical treatments costs, especially between developed and developing countries. Their analyses of the considerable variations in the costs of medical therapies suggest that filtering surgery could be a viable option to improve long-term accessibility to glaucoma treatment in developing nations by reducing the rate of economic noncompliance.
