The review by Margolin (2020) explores the causes, work-up, and treatment options for diplopia (double vision). While highlighting the importance of thorough history-taking and basic examination skills in diagnosing diplopia, the review overlooks several disorders that can manifest with diplopia, including myopathy of extraocular muscles. The author suggests that a wider range of conditions, such as metabolic myopathy and immune-mediated neuropathies, should be considered in the differential diagnosis. The review emphasizes the need for a comprehensive work-up to include these often-neglected causes of diplopia, as early identification and treatment can lead to better outcomes.
