Both acute and chronic exposure to carbon monoxide (CO) gas can have serious and permanent effects on a person’s health and vision, especially if left untreated. The brain and eyes are at risk upon exposure to this clear, odorless gas due to the large oxygen demands of these structures. This teaching case report highlights the need for eyecare professionals to recognize the possible ocular, sys...

Background: Knowing the pattern of carbon monoxide (CO) poisoning in each region is vital for enhanced health planning. This study was designed to evaluate the epidemiologic pattern of unintentional acute CO poisoning in major cities of Fars province, southwest of Iran.  Methods: This one-year cross-sectional study was carried out on unintentional CO poisoning incidents in Fars province, Iran,...

The etiology of Parkinsonism may be multifactorial. Exposure to certain toxins (for example manganese dust, carbon disulfide) and severe carbon monoxide poisoning may play a role. It is also seen in people who took MPTP recreationally — which converts to a neurotoxin in the body. Other drugs and medication can cause a reversible form of this disease. Postencephalitic parkinsonism is becoming mo...

Carbon monoxide, a gas originating from incomplete combustion of carbon-based fuels, is an important cause of human deaths. In this paper, we describe an unusual carbon monoxide poisoning in a dwelling without obvious sources of combustion gases, for which two adults had to be treated in a hyperbaric chamber. Carbon monoxide readings were taken in the house and in the neighboring homes. Methane...
