What Researchers Did
Researchers reported a case of severe optic neuropathy in a 65-year-old man following dichloromethane inhalation.
What They Found
They found that the patient developed severe optic neuropathy, presenting with visual acuity of 0.3 in both eyes and critical flicker frequency values of 30 and 25 Hz. Goldmann perimetry showed concentric contractions of the visual field by 10 degrees in both eyes, and despite treatment, visual disturbance and optic nerve atrophy worsened.
Canadian Relevance
This study has no direct Canadian connection as it is a single case report from outside Canada.
Study Limitations
A key limitation of this study is that it is a single case report, which restricts the generalizability of its findings to a broader population.
