What this trial studies

This study evaluates the effectiveness of hyperbaric oxygen therapy in providing neuroprotection for patients suffering from optic neuropathy. Participants will receive either hyperbaric oxygen treatment or a sham treatment to assess the potential benefits of the therapy. The study aims to determine if this innovative approach can improve vision and overall eye health in affected individuals. Eligible participants must be at least 18 years old and have clinical evidence of optic neuropathy.

Why it matters

Potential benefit: If successful, this therapy could offer a new treatment option for patients with optic neuropathy, potentially improving their vision and quality of life.

How similar studies have gone: While hyperbaric oxygen therapy has been explored in various contexts, its application specifically for optic neuropathies is relatively novel and has not been extensively tested.
