About two years ago our attention was drawn to glassy ring-like structures at the periphery of the posterior surface of the cornea. It soon became evident that these bands corresponded to the so-called posterior embryotoxon of the cornea (Embryotoxon corneae posterius, Axenfeld¹), posterior marginal dysplasia of the cornea (Streiff²), congenital hyaline membranes on the posterior surface of the cornea (Mann³), or peripheral refractile postcorneal rim (Graves⁴). Once our interest in this subject was awakened, we devoted a close study to the limbus of all patients whom we saw and performed a slit-lamp gonioscopic examination on those who presented to external slitlamp study an unusual appearance of the limbus or of the periphery of the cornea.

These clinical investigations were followed by a careful study of 600 pathologic specimens of eyes, and this study, in turn, prompted us to extend our investigations to the chamber angle of . . . [Full Text PDF of this Article]
