What Researchers Did
Researchers reported a rare case of central retinal artery occlusion (CRAO) in a 23-year-old woman with persistent truncus arteriosus (PTA) and single atrium.
What They Found
A 23-year-old woman experienced sudden painless visual loss in her left eye, with visual acuity reduced to light-perception. Fundoscopic examination revealed signs consistent with CRAO, including retinal ischemic whitening and a "cherry-red spot." An echocardiogram subsequently diagnosed persistent truncus arteriosus and single atrium.
What This Means for Canadian Patients
This case highlights that patients experiencing central retinal artery occlusion may have underlying congenital heart abnormalities. Ophthalmologists should consider investigating for such cardiac conditions as potential sources of emboli in CRAO patients.
Canadian Relevance
This case report does not have a direct Canadian connection.
Study Limitations
As a single case report, the findings cannot be generalized to a broader patient population.
