ABCA4 and inherited retinal dystrophy: These are in fact present in a variety of inherited retinal dystrophies, but double rings such as the ones described herein, are rarer and to the best of our knowledge, have been reported in only a few genotypes to date, such as the retinal dystrophies associated with disease-causing variants in ABCA4 (OMIM *601691), NR2E3 (OMIM *604485), EYS (OMIM *612424), and USH2A (OMIM *608400).28
