Karbon Monoksit Zehirlenmesinin Neden Olduğu Görme Kaybı Için Hiperbarik Oksijen Tedavisi

Öz

Beyin ve kalp gibi yüksek oksijen (O2 ) harcayan organlar çok kolay bir şekilde karbon monoksit (CO) toksisitesinden etkilenirler. Beyin dokusunda gri maddede ve özellikle globus pallidusta sıklıkla bilateral olan iskemik lezyonlar ve nekroz en sık görülen değişikliklerdir. Zehirlenmenin şiddetine bağlı olarak serebral, kardiyak bulgular oluşabileceği gibi nadiren de olsa görme kusurları oluşabilir. Görme bozuklukları genellikle komadan çıkan hastalarda görülür. Bu sunumda CO zehirlenmesi sonucu ileri derecede görme kaybı gelişen ve yapılan uzun süreli hiperbarik oksijen tedavisine tam yanıt veren bir olgudan bahsettik.

Hyperbaric Oxygen Treatment for Visual Loss Due to Carbon Monoxide Intoxication: A Case Report

Öz

High oxygen (O2) consuming organs such as the brain and the heart are easily affected by carbon monoxide (CO) intoxication. The most frequent changes are bilateral ischemic lesions and necrosis in the grey substance of brain tissue, particularly in the globus pallidus. Depending on the severity of intoxication, cerebral and cardiac findings may occur as well as visual impairment, although rare. Visual disorders may develop in patients recovering from coma. In this case report, we present a case with severe loss of vision consequent to CO intoxication, who demonstrated a complete response to long-term hyperbaric oxygen treatment

Anahtar Kelimeler

• Carbon monoxide intoxication, visual loss, hyperbaric oxygen treatment
