[An analysis of ocular manifestations in cases with tumors of accessory nasal sinuses].

The ocular manifestations of 60 cases with tumors of accessory nasal sinuses were reported. They were proptosis, impairment of ocular movement, diplopia, decrease or loss of visual acuity, ptosis, etc. Of them, 42 patients came to the ophthalmology department first. All the patients were diagnosed by computerized tomography (CT scan) and pathological findings. Operative treatment was applied in 48 cases. 32 cases had improvement in ocular symptoms. Particular attention was paid to the analysis of the causes of the patients, ocular symptoms and signs. They are due to the close anatomical relationship between accessory nasal sinuses and the orbit and optic nerve canal. CT scan is helpful to the early diagnosis of the disease.
