作者分析1932～1961年中所见56例视神经胶质瘤,年龄均在16岁以下。26例仅侵及视神经;平均观察12年,共中33例追踪观察5年以上,21例10～20年。56例中40例经病理组织检查,均为星形细胞瘤。其余16例的诊断有下列依据:(1)视交叉胶质瘤9例:视乳头苍白,视力下降;气脑及 X-相见视神经孔为6.5～7毫米,约比对侧大1毫米;蝶鞍前床突下方有肿物压成的陷凹;或手术时见到肿物。(2)视神经胶质瘤7例:眼球突出,视乳头苍白,视力下降,视神经孔扩大。结果:(1)年龄:一般均在幼儿年龄;有6人出生时,6人为2岁,6人大于10岁时发生。(2)症状:56人中首发症状为视力减退者28人,眼球突出者25人;就诊时检查,视力已减退者52人。眼球突出共29人,一般较健侧高出不超过3毫米;为本病相当可靠的诊断体征。有视野改变者12人,缺损
The authors analyzed 56 cases of optic nerve glioma seen from 1932 to 1961, all under the age of 16. Twenty-six cases only invaded the optic nerve; the mean observation period was 12 years. A total of 33 cases were followed up for more than 5 years and 21 cases were 10 to 20 years old. Of the 56 cases, 40 cases were astrocytomas after pathological examination. The diagnosis of the remaining 16 cases had the following criteria: (1) 9 cases of optic chiasm glioma: pale papilla, decreased vision; optic nerve and X-phase seen optic nerve hole was 6.5-7 mm, approximately 1 mm larger than the contralateral side; There is a depression underneath the tumor in the front of the sella, or a tumor is seen during surgery. (2) 7 cases of optic nerve glioma: prominent eyes, pale papilla, decreased visual acuity, and enlarged optic nerve pores. Results: (1) Age: Generally at the age of children; when 6 people were born, 6 were 2 years old, and 6 people were older than 10 years old. (2) Symptoms: Among the 56 patients, the first symptoms were 28 with vision loss and 25 with prominent eyes. When examined, there were 52 people with diminished visual acuity. A total of 29 eyeballs protrude, which is generally no more than 3 mm higher than the healthy side; this disease is a very reliable diagnostic sign. 12 people with vision change, defect
