Carbon Monoxide-Induced Cortical Visual Loss: Treatment with Hyperbaric Oxygen Four Years Later

Carbon monoxide-induced cortical visual loss: treatment with hyperbaric oxygen four years later.

OBJECTIVE We present a patient who developed visual loss after carbon monoxide (CO) poisoning and was treated with hyperbaric oxygen. CLINICAL PRESENTATION AND INTERVENTION A 21-year-old woman poisoned with CO (with coma lasting 4 h and carboxyhemoglobin level 46%) developed seizures and cortical blindness 3 days after poisoning. Four years later, her visual acuity was 0.2 in both eyes. An (1...

Visual loss as a late complication of carbon monoxide poisoning and its successful treatment with hyperbaric oxygen therapy.

PURPOSE To present recovery from vision loss due to CO poisoning with Hyperbaric Oxygen (HBO) therapy in two patients. METHODS Two female patients developed visual deterioration after carbon monoxide (CO) poisoning and were treated with hyperbaric oxygen therapy (HBO). Clinical examination, including visual acuity assessment, visual field examination and visual evoked potentials (VEPs) before...

Hyperbaric oxygen in carbon monoxide poisoning.

Hyperbaric oxygen for acute carbon monoxide poisoning.

BACKGROUND Patients with acute carbon monoxide poisoning commonly have cognitive sequelae. We conducted a double-blind, randomized trial to evaluate the effect of hyperbaric-oxygen treatment on such cognitive sequelae. METHODS We randomly assigned patients with symptomatic acute carbon monoxide poisoning in equal proportions to three chamber sessions within a 24-hour period, consisting of eit...

Hyperbaric oxygen therapy for pediatric patients with carbon monoxide poisoning.

We read with great interest the article by Yarar et al. entitled “Analysis of the features of acute carbon monoxide poisoning and hyperbaric oxygen therapy in children”1. Carbon monoxide (CO) poisoning, with its high morbidity and mortality, remains an important public health problem. The data about CO poisoning in pediatric patients are limited and the contributions of Yarar et al. are of valu...
