视神经胶质瘤(optic glioma)起源于视神经内神经胶质,属于良性或低度恶性肿瘤,占所有眼眶肿瘤4%,占所有颅内肿瘤2% ,占所有颅内胶质瘤4%,占视神经原发肿瘤66%。根据发病年龄,分为2组:儿童组和成人组,儿童视神经胶质瘤为毛细胞性星形细胞瘤,多发生于10岁以下儿童,发病高峰...
MRI demonstrates a 2.6 x 2.0 cm heterogeneously enhancing, completely intraorbital left optic nerve glioma. It exhibits mild mass effect on the medial and lateral recti muscles and posterior aspect of the left globe. The right optic nerve, e...

gliomaoptic pathwayOptic pathway glioma (OPG) is a rare brain tumor that occurs more commonly during early childhood and is frequently associated with neurofibromatosis type 1 (NF1). In this study, our aim was to describe the characteristics, management, and outcome of patients with OPG. We ...
Optical coherence tomography (OCT) is a non-invasive imaging technology, which may be used to generate in vivo quantitative and qualitative measures of retinal structure. In terms of quantitative metrics, peripapillary retinal nerve fiber layer (pRNFL) thickness provides an indirect evaluation of axona...
Improvement of visual acuity occurred in one child after operation of a large suprasellar tumor and deterioration in one patient after biopsy of a chiasmal glioma. The neuroradiological follow-up of the 13 not-operated and not-radiated patients (four optic nerve and nine chiasmal gliomas) was ...
