TGFBI and Thiel-Behnke corneal dystrophy: RBCD and TBCD are associated with similar phenotypes, presenting with recurrent corneal erosions and the development of a “geographic” (RBCD) or “honeycomb” (TBCD) pattern of the anterior corneal layer.[1–3] These two dystrophies share a common genetic origin, with RBCD and TBCD associated with the p.(Arg124Leu) and p.(Arg555Gln) mutations in the transforming growth factor beta induced (TGFBI) gene on chromosome 5q31, respectively.[4–7]
