Answer

Unlike ethanol or isopropanol, methanol does not cause nearly as much of an inebriated state. If a patient has coingested ethanol, signs or symptoms specific to methanol intoxication are delayed.

The patient may be hyperventilating.

If vision is impaired, ocular examination may reveal dilated pupils that are minimally or unreactive to light with hyperemia of the optic disc. Over several days, the red disc becomes pale, and the patient may become blind. Typically, subjective complaints precede physical findings in the eye.
