The study aimed to examine changes in retinal and choroidal blood vessels in patients with coronary artery stenosis using optical coherence tomography angiography (OCTA).
It involved 100 participants, split into an observation group (50 patients with angina diagnosed with coronary artery stenosis) and a control group (50 healthy adults), to assess vessel density parameters.
Results showed that the coronary artery stenosis group had lower densities in key retinal vessels and a higher FAZ perimeter, making the FAZ perimeter a significant predictor of coronary artery stenosis risk.
