ABCA4 and atrial fibrillation: Figure 3a shows imaging from the right eye in her early 60s. VA was 6/9.5 in both eyes at the time. CFP imaging shows yellow pisciform flecks in the posterior pole, sparing the fovea and with a reticular pattern temporally. There is a round patch of RPE atrophy along the papillomacular bundle. AF imaging shows that the flecks are mixed hypo- and hyper-AF and demonstrates peripapillary sparing. OCT imaging shows patchy outer retinal atrophy, with foveal preservation. Genetic testing demonstrated two causative ABCA4 variants in this patient (Table 1).
