Three cases of paranasal mucocele with blindness were reported.Case 1. The patient, a 69-year-old female, complained of headache, right blindness, and right exophthalmos which took a very slow course. CT showed a large high density area in the sphenoid sinus and right ethomoid cells. Under the suspection of a sphenoid mucocele or a pituitary tumor, an operation was undertaken. It was confirmed that a large sphenoid mucocele had destroyed the orbital wall and was pressing upon the optic nerve.Case 2. The patient, a 58-year-old male, complained of left exophthalmos and left blindness which took a very rapid course. He suffered from fever, left orbital pain and swelling of the left eye for about ten days, and then he lost his sight. It seemed that these symptoms were caused by orbital cellulitis complicated with frontal pyocele.Case 3. The patient, a 36-year-old female, complained of left blindness without exophthalmos. On operation it was revealed that ethomoid mucocele pressed against the optic nerve and caused the loss of sight in the left eye.Although other symptoms were alleviated, the visual acuity remained null in all three cases. Review was made in particular of the mechanism of blinding caused by mucocele.
