A 55-year-old man complained something unusual of the left visual field. In ophthalmology he had a nasal and lower altitudinal quadrantanopsia of his left eye field. CT and MRI showed severe maxillary sinusitis, but no lesions in the posterior ethmoid or sphenoid sinuses. The maxillary sinus was well developed and the top of the sinus was very close to the optic nerve. 47 days after Caldwell-Luc's operation, the field of vision became near normal.<BR>When we see medial-inferior quadrant blindness, we infer a lesion in the lateral-superior part of the optic nerve, but in this case MRI and CT scan showed maxillary sinusitis only. We presume that severe maxillary sinusitis has caused the blindness.
