Clarification on the terminology “EOM” in ophthalmic practice

Abstract: Dear Editor, Accurate terminology in ophthalmology is essential for effective communication among healthcare professionals and optimal patient care. I am writing to address a common misunderstanding in ophthalmic practice regarding the terminology “EOM.” It is observed that the term “EOM” is frequently expanded and presented as “extraocular movements,” which is, in fact, an incorrect interpretation.[1,2] Instead, “EOM” accurately stands for “extraocular muscles.” Misinterpretation of terms such as “EOM” can lead to confusion and potential errors in diagnosis and treatment. This incorrect usage of terminology is mainly observed on several online platforms,[1,3-5] YouTube videos,[6] and even in scientific publications.[2] It is also frequently observed among postgraduate residents during their clinical case presentations. Educational interventions aimed at addressing this misconception early in their training are crucial to ensure the accurate transmission of knowledge within the field of ophthalmology. Extraocular muscles, as the name implies, are the muscles located outside the eyeball and are responsible for the movement of the eyeball itself. These muscles include the lateral rectus, medial rectus, superior rectus, inferior rectus, superior oblique, and inferior oblique. They play a crucial role in directing the gaze and facilitating binocular vision. In contrast, intraocular muscles encompass the muscles within the eyeball, such as those of the iris and ciliary body, which are involved in processes such as accommodation and pupil constriction or dilatation. Therefore, using the term “EOM” to describe the action of these muscles is inaccurate and potentially misleading. It implies movement external to the eyeball, whereas the term “EOM” accurately describes their anatomical location and function. To avoid confusion and uphold scientific accuracy, it is recommended to use the term “extraocular muscle action” when referring to the movements of these muscles. Alternatively, the term “ocular movements” can be employed to describe the movement of the eyeball as a whole. By clarifying this terminology, we can ensure consistency and precision in communication within the field of ophthalmology, ultimately benefiting students, practitioners, and patients alike. Thank you for considering this important clarification.
