Figure 1. Phenotypes of Thiel-Behnke corneal dystrophy (all carried the R555Q mutation of the heterozygous form). A: An 11-month-old female, irregularly shaped scattered opacities with non-involvement of the peripheral cornea in the Bowman layer. B: A 26-year-old female, subepithelial reticular (honeycomb) opacities with non-involvement of the peripheral cornea. C: A 43-year-old female, opacities united, resulting in denser and larger opacities. D: A 69-year-old female, opacities, progressing to the deep stromal layers and corneal periphery.
