Quantitative fundus autofluorescence in recessive Stargardt disease (STGD1). A. qAF8 values (blue circles) are plotted as a function of age. Comparison is made to mean (solid red line) and 95% confidence intervals (dashed lines) for healthy eyes. B. Linear regression analysis indicates good correspondence between left (OS) and right (OD) eyes. C. Early age of STGD1-onset can be associated with higher levels of qAF. D. qAF8 versus age is plotted in relationship to some homozygous (p.G1961E; p. P1380L) and compound heterozygous (p.[G1961E; P1380L] [p.G1961E; p. L541/A1038V]) ABCA4 mutations. Insets at top, color-coded images and corresponding qAF values are shown for patients carrying homozygous G1961E and P1380L mutations. Adapted from Burke et al. (2014).
