Background:

Carbon monoxide (CO) poisoning is a common environmental hazard.
Retinal manifestations of CO intoxication are not well-documented.
Understanding CO retinopathy is essential for clinical management.

Observation:

Three family members exposed to CO showed distinct fundus findings.
Findings ranged from normal to severe retinal hemorrhages, venous tortuosity, and disc edema.
Carboxyhemoglobin levels were comparable across all affected individuals.

Findings:

The study highlights the variable clinical presentation of carbon monoxide retinopathy.
Retinal hemorrhages, venous changes, and optic disc edema indicate severity.

Absence of hypertension, diabetes, or anemia rules out confounding factors.

Implications:

Variable fundus findings underscore the need for thorough ophthalmologic examination in CO poisoning.
Early detection of CO retinopathy can guide treatment and prognosis.
Recognizing diverse presentations aids in preventing potentially lethal outcomes.
