Clinicians frequently uncover optic pathway gliomas in patients with neurofibromatosis type 1, but most cases can be managed conservatively, researchers at the American Academy of Ophthalmology 2021 meeting suggested. The findings were developed from the largest study in the English literature to investigate visual outcomes of optic pathway gliomas in patients with neurofibromatosis type 1, according to the presentation.

The study was conducted at a tertiary cancer center to measure visual outcomes in patients with optic pathway gliomas. Researchers used data from 1382 patients seen between 2000 and 2020. Investigators accounted for patient demographics, tumor location, treatment, and progression of disease. Within the inclusion criterion were 210 patients (average age 32.4, 121 women). Of those, 89% are currently alive, according to investigators, and 11% are now deceased. The most common symptom associated with optic pathway gliomas in patients with neurofibromatosis type 1 was blurred vision. Seven patients presented with nystagmus. 

While some patients were treated with recently FDA-approved MEK inhibitors, most were managed conservatively, according to the presenters.
