Background:

Diabetes mellitus is a common condition associated with various visual complications.
Accurate diagnosis of visual impairment in diabetic patients is crucial for effective treatment.
Drug-induced toxicities can affect the optic nerve, leading to vision loss.

Observation:

A 65-year-old woman with adult-onset diabetes developed toxic optic neuropathy.
The patient was undergoing treatment with chlorpropamide (Diabenese).
Visual acuity improved significantly after chlorpropamide therapy was discontinued.

Findings:

Chlorpropamide therapy was identified as the cause of toxic optic neuropathy.
Discontinuation of chlorpropamide led to the resolution of optic neuropathy.
