    Summary
    This summary is machine-generated.

    Radiotherapy may improve vision in patients with optic nerve glioma involving the chiasm. While survival rates are unaffected by treatment, radiotherapy offers a better chance of visual improvement compared to other interventions.

    Area of Science:

    • Ophthalmology
    • Neuro-oncology
    • Radiation Oncology

    Background:

    • Optic nerve glioma involving the chiasm is a rare tumor.
    • Tumor behavior can be benign, particularly in younger patients.
    • Treatment options and their efficacy require further investigation.

    Purpose of the Study:

    • To evaluate the effectiveness of radiotherapy for optic nerve glioma involving the chiasm.
    • To compare radiotherapy outcomes with other treatment modalities.
    • To determine the optimal management strategy for this condition.

    Main Methods:

    • A series of 10 patients treated with radiotherapy was analyzed.
    • Data from six additional series were pooled for meta-analysis.
    • Follow-up periods ranged from six months to 17 years.

    Main Results:

    • No deaths occurred due to the tumor in the studied series.
    • Four patients experienced vision improvement following radiotherapy.
    • Radiotherapy showed a higher likelihood of vision improvement than spontaneous recovery or surgery.

    Conclusions:

    • Radiotherapy is likely the preferred management for optic nerve glioma involving the chiasm.
    • Surgery, including biopsy, may negatively impact vision.
    • Further research is warranted to confirm the long-term benefits of radiotherapy.
