obsolete recurrent pediatric optic nerve glioma

Based on the provided context, here are the signs and symptoms of recurrent pediatric optic nerve glioma:

• Visual problems: As the tumor progresses, it presses on the optic nerve, causing vision problems [11][12]. This can include decreased visual acuity, visual field deficits, and blindness in about 5 percent of cases [11].
• Optic disc swelling and/or disc pallor: Symptomatic OPG may present with optic disc swelling and/or disc pallor [3][6].
• Proptosis: Proptosis (bulging eyes) can occur due to the tumor's growth along the optic nerve [4][13].
• Raised intracranial pressure: In some cases, children may experience raised intracranial pressure, diencephalic syndrome, and hydrocephalus [5].
• Blurred vision: Symptoms can include blurred vision, which was reported in one patient [4].

It's worth noting that not all patients with recurrent pediatric optic nerve glioma will exhibit these symptoms. In some cases, the tumor may be asymptomatic or cause only mild visual disturbances.

[11] An optic nerve glioma (also called an optic pathway glioma) is a slow-growing brain tumor that arises in or around the optic nerve, which connects the eye to the brain. As the tumor progresses, it presses on the optic nerve, causing a child’s vision to worsen.Blindness may occur only in about 5 percent of cases. [12] As the tumor progresses, it presses on the optic nerve, causing vision problems. While these are serious tumors, they have a high cure rate. Optic nerve glioma accounts for five percent of all childhood brain tumors. Nearly 75 percent of optic nerve gliomas, which may affect one or both eyes, occur in children younger than ten years old.
