  1. In total, 4 of the 18 eyes in the AWE group and 1 of the 15 eyes in the phlyctenular keratitis/ocular rosacea group showed limbal involvement in all the four quadrants of the limbal area. Accordingly, there are presumed-healthy sites of the limbus in the 14 disease eyes in both the AWE group and the phlyctenular keratitis/ocular rosacea group.
