Dear Sirs,

Windmill nystagmus is characterized by a clock-like rotation of the direction of nystagmus [1]. Even though various patterns of variant windmill nystagmus have been described [2, 3], the typical pattern of windmill nystagmus has only once been described in a patient with acquired blindness [1]. We report another case of windmill nystagmus that was observed only 3 months after visual loss.

A 47-year-old man was referred for further evaluation of progressive visual loss in both eyes for 3 months. Under the suspicion of atypical optic neuritis, intravenous methylprednisolone, 1 g per day, had been administered for 10 days in another hospital, but his visual acuity had deteriorated.

On examination, he was not able to perceive light in the left eye, and only able to count fingers at 50 cm in the right eye. Both pupils were measured at 5 mm and hardly responded to light or near stimuli. Optic discs were pale in both eyes (Fig. 1a). Video-oculography documented intermittent...
