What does 'extraocular movements intact' (EOMI) indicate?

The phrase 'extraocular movements intact' signifies that the extraocular muscles, which control eye movement, are functioning normally. This means the eyes can move smoothly and correctly in all directions, indicating that there are no restrictions or weaknesses in the muscles surrounding the eye.

When a clinician assesses extraocular movements, they are checking for a proper range of motion — which indicates healthy neuromuscular function. If the extraocular movements were not intact, it could suggest potential underlying issues such as muscle dysfunction or neurological deficits. Factors such as a firm mass in the eye, damage to the optic nerve, or developing cataracts would present different symptoms or findings, and would not be classified as 'intact extraocular movements.' Recognizing that EOMI is synonymous with normal muscle function helps in accurate clinical assessments and patient care.
