Visual acuity measured after correction with AOSLO is significantly correlated with visual acuity measured with numbers of letters read using ETDRS charts. Correlation of acuity measured as letters read on the ETDRS chart and AOSLO acuity measured as MAR, normal subjects: r = −0.02, 95% CI: −0.9 to 1.0; IRD patients: r = −0.84, 95% CI: −0.9 to −0.6. Normal subjects: blue circles; IRD patients: red Xs.
