Background: Visual loss is the most common ophthalmologic manifestation of intracranial meningioma which predominantly
located in the tuberculum sellae and sphenoid bone.
Objective: To determine the correlation between intracranial meningioma and its ophthalmologic manifestations and visual
outcome.
Material and Method: Patients with intracranial meningioma in Siriraj Hospital were retrospectively reviewed. Demographic data, ophthalmologic manifestations, location of tumor, treatment and visual outcome were collected and analyzed.
Results: Fifty patients, who underwent surgical tumor resection, were divided into 2 groups regarding preoperative visual status, including group I (preoperative VA >6/60) consisting of 26 patients (52%) and group II (preoperative VA <6/60 with exclusion of patients with blindness) consisting of 24 patients (48%). There was statistically significant improvement of postoperative VA in group II (p = 0.001). Regarding duration of preoperative visual symptom, 50 patients were divided into
group I (24 cases with the duration <7 months) and group II (26 cases with the duration >7 months). There was no correlation between duration of preoperative visual symptom and postoperative visual outcome.
Conclusion: Visual improvement after surgical treatment was significantly found in patients with intracranial meningioma
who have VA <6/60.
