CRB1 and retinal disorder: This study primarily aims to assess retinal sensitivity using the S-MAIA and retinal volume using SD-OCT in a cohort of prospective patients with CRB1-associated retinopathies who were able to undergo best corrected visual acuity (BCVA) assessment using the ETDRS chart and had a baseline visual acuity in the better seeing eye of equal or better than 1.00 logMAR.
