—The CASE REPORT of a nonherpetic dendriform subepithelial lesion of the cornea by Seedor and Waring1 was most interesting, and the corneal lesions were particularly severe. The authors suspected an insult to the corneal epithelium as the cause.This lesion brings to mind a milder version, first reported by Korb,2 that may be related to this problem and that presents a similar but less severe appearance. Korb reported a characteristic deep epithelial grayish white configuration associated with polymethylmethacrylate (PMMA) rigid contact lens-induced corneal hypoxia complicated by chronic microcystic edema and corneal hypoesthesia. He reported that the visual acuity with contact lenses remains as expected, usually 20/20. However, visual acuity with ophthalmic lenses cannot be corrected to the expected level and may vary from 20/25 to 20/70. Korb referred to these lesions as edematous corneal formations. He reported that in severe instances, the disturbance appears to
