During the physical examination, a clinician will often test the individual’s sight while covering one eye at a time to differentiate between binocular and monocular diplopia. Additionally, the clinician may ask the individual to move their eyes in different directions, which can show whether a particular eye muscle or cranial nerve is affected. If only one muscle is affected, the diplopia will be worse when the individual looks in the direction of the affected eye muscle. Depending on the suspected cause, blood tests may be performed to diagnose the condition, such as testing for myasthenic antibodies in the case myasthenia gravis is suspected. Occasionally, magnetic resonance imaging (MRI) or other appropriate imaging will be performed to diagnose a condition affecting the brainstem, like a stroke.
