Radiation-induced optic neuropathy: a review

Area of Science:

• Oncology
• Neurology
• Radiology

Background:

• Radiation therapy is a standard treatment for head and neck and CNS tumors.
• Increased patient survival due to novel therapies like immunotherapy leads to more frequent radiation-related complications.
• Radiation-induced optic neuropathy is a serious concern due to its rapid onset and potential for severe, bilateral vision loss.

Purpose of the Study:

• To review the presentation and etiology of radiation-induced optic neuropathy.
• To discuss recent diagnostic advancements, including innovative MRI techniques.
• To outline evidence-based best practice treatment options for this condition.

Main Methods:

• Literature review of recent evidence-based medicine.
• Focus on innovative diagnostic techniques like MRI.
• Analysis of current treatment strategies.

Main Results:

• Radiation-induced optic neuropathy presents with rapid vision loss.
• Early recognition and intervention are critical due to a narrow therapeutic window.
• Advanced MRI techniques offer improved diagnostic capabilities.

Conclusions:

• Radiation-induced optic neuropathy requires vigilant monitoring of high-risk patients.
• Prompt diagnosis and treatment are essential to prevent irreversible vision impairment.
• This review provides an up-to-date overview of diagnosis and management.
