Visual function in patients with the p.Ala1773Val mutation in ABCA4. A: Three different kinetic perimetry patterns in patients with ABCA4 retinopathy. Absolute central scotoma involving the central 10 degrees of vision (top, black shadow). Relative central scotoma involving the central vision (middle, gray shadow). Absolute central scotoma associated with reduction of the peripheral visual field (bottom, black shadow) B:Measured electroretinography (ERG) recordings shown as the percentage of cone and rod function compared with normative data in ten patients with the p.Ala1773Val mutation in ABCA4.
