AIMS: To investigate the association between optical coherence tomography (OCT) biomarkers and contrast sensitivity (CS) measured by the quantitative contrast sensitivity function (qCSF) in retinal artery occlusion (RAO).
METHODS: This cross-sectional study included RAO patients and age-matched controls undergoing visual acuity (VA), qCSF testing and spectral-domain OCT. Only eyes with VA≥20/200 were included for reliable CS evaluation. OCT quantified retinal layer thickness, ischaemic lesion size and distance from ischaemia to the fovea. Linear regression analyses were performed.
RESULTS: 27 RAO eyes (17 branch RAO (BRAO), 63%) and 48 control eyes were included. All qCSF metrics were significantly reduced in RAO and central RAO compared with controls (p≤0.012). In BRAO, AULCSF and low spatial frequency CS (1-6 cycles per degree (CPD)) were significantly lower than controls (p≤0.011), whereas VA showed no significant difference. Univariable regression analysis revealed inner nuclear layer (INL) thickness (0-3 mm) was significantly associated with VA and all qCSF parameters (p<0.05). Larger ischaemic areas and closer foveal proximity correlated with worse AULCSF, contrast acuity and high spatial frequency CS (6-18 CPD; p<0.05), but not VA. Multivariable regression confirmed INL (0-3 mm) thickness was associated with VA and CS at 3 and 6 CPD (p<0.05), and foveal proximity with CS at 18 CPD (p=0.045).
CONCLUSIONS: qCSF shows strong correlations with INL thickness and ischaemia metrics in RAO eyes, supporting it as a valuable complementary functional measure to VA, and a meaningful clinical endpoint in RAO evaluation, particularly in foveal-sparing cases.
