( A – D ) Foveal thickness, nasal-to-temporal thickness and relation to FAZ area. (A) Average foveal thickness is similar in Alport patients, autosomal-recessive carriers and controls, whereas Alport patients exhibit a higher interindividual variability. (B) Nasal-to-temporal retinal thickness difference is significantly elevated in Alport Patients. Again, autosomal-recessive carriers and controls do not differ significantly. (C) FAZ area is highly correlated with the foveal thickness in AS patients. (D) shows that a more Alport-specific characteristic, the nasal-to-temporal thickness difference, does not exhibit a clear correlation to the FAZ area.
