Background

Visual impairment is the most common complications of methanol poisoning.

Purpose

Visual impairment is the most common complications of methanol poisoning.

Methods

Diagnosed with methanol poisoning between 2018 and 2022 who were hospitalized in the poisoning centers at Urmia were evaluated.

n = 124 patients

Results

more than 1 in 8 patients lost their sight entirely, a severe, permanent outcome

60.5%

Complete recovery

6.5%

Decreased visual acuit

13.7%

Blindness

19.4%

Died

More results

Blurred vision with 42.7% and decreased level of consciousness with 33.1% were the most common complaints of patient, and ethanol therapy with 91.9% was the most common treatment approach.

More results

The final outcome was not correlated to the amount of consumed alcoholic beverages ( p = 0.21), CO2 level ( p = 0.33) and gender ( p = 0.35), but the H and HCO 3 of deceased people were significantly lower ( p > 0.001) than survived patients.

Conclusion

Early referral and controlling the blood H play critical role in managing the patients with methanol poisoning.
