This rare form of dissociated nystagmus probably reflects a “dual abnormality mechanism” comprising the coexistence of an asymmetric conduction delay in the optic nerve and a strategic network disruption in brainstem gaze holding centres. For the clinician it is important to recognize this rare neuro-ophthalmologic syndrome and be aware of its benign nature. © 2022 Elsevier B.V." }
