Fake alcohol poisoning, which means methanol poisoning, has the following symptoms: 1. The effect on the optic nerve, which can appear to have blurred vision and diplopia, i.e., seeing things with two double shadows, i.e., the performance of not being able to see clearly; 2. The performance that leads to acidosis, which is manifested by deep and big breathing, i.e., the suffocating feeling of not being able to breathe. The appearance of poisoning must be treated early in the hospital, and if it is prolonged, it may cause irreversible damage to the optic nerve, leading to the adverse consequences of blindness and vision loss. The key to methanol poisoning is early detection and early treatment. Treatment of methanol poisoning can be detoxified with ethanol. During the consultation, patients should be asked about their medical history and whether any of the people who drank with them had similar symptoms. If more than three of them have similar blurred vision and visual impairment, methanol poisoning can be highly suspected and should be proven by drawing blood to check the concentration of methanol in the blood to see if it is methanol poisoning. If it is, one should receive ethanol detoxification therapy, which is ultimately a detoxification with real alcohol.
