Abstract

|
In a series of 93 cases of verified brain tumors visited to The National Medical Center from Nov. 1958 to March 1963 were studied clinically in regard to the ocular symptoms. The results of the study include following findings
1. 81.3% of visual disturbances were present including 43 cases of monocular and binocular blindness.
2. Among 46 cases who were able to be examined, 78.7% showed abnormal visual fields. The most frequent type of field defect was homonymous hemianopsia, which showed high incidence in cerebral paragonimiasis.
3. The incidence of papilledema was 33.3%. They were mostly bilateral, and showed much higher incidence of 64.2% in infratentorial tumors.
4. Optic atrohy was found in 36.5%. They were mostly of bilateral affection, There were no big difference between the incidence of primary optic atrophy and that of secondary. Primary atrophy were seen most frequently in cases of cerebral paragonimiasis as well as frontal and seilar region tumors,
5. The incidence of abnormal pupillary reflexes was 48.3%. Most of these cases are due to amaurotic mydriasis. Anisocoria occurred 17.2% of the series,
6. The incidence of nystagmus was 17.2% and was most frequently seen in cases of infratententorial tumors.
7. 7.5% of abducens palsy were the most frequent occurrence among-extraocular muscle palsies.
8. It was specific that the affection of corneal sensibility was ipsilateral to the location of the tumors. The incidence of corneal affection was higher inn cases of infratentorial tumors than that of supratentorial group.
9. Lagophthalmos occurred in 10.7% of the cases. All of them were due to facial palsy.
