The main goal of treating optic gliomas is to preserve vision for as long as possible. [5] The tumor's slow and self-limiting growth indicates that it is not immediately problematic in most benign cases, with long-term studies showing that people with optic glioma may still have stable functional vision without intervention.
The diagnosis may be suspected based on symptoms and MRI and confirmed by tissue biopsy. [6] [7] Blood tests may show anaemia, and less commonly a low white blood cell count and low platelet count. [5] Treatment may involve surgery, chemotherapy, radiation therapy, and certain medicines. [7]
It results in the following signs, which can be extremely distressing to the patient: [4] Most frequent are symptoms due to conjunctival or corneal irritation: burning, photophobia, tearing, pain, and a gritty or sandy sensation.

Von Graefe's sign is the lagging of the upper eyelid on downward rotation of the eye, indicating exophthalmic goiter (Graves' disease). [1] It is a dynamic sign, whereas lid lag is a static sign which may also be present in cicatricial eyelid retraction or congenital ptosis.
Depending on the initial location of the tumor, visual loss may be accompanied by exophthalmos, extraocular motility Optic nerve melanocytoma does not usually produce symptoms or grow. If they slowly grow, optic nerve melanocytoma can produce afferent pupillary defects (30%), subretinal fluid (10%), and an enlarged blind spot (75%).
