The phenotypic features of seven patients from the three families affected by lattice corneal dystrophy type I are shown. Corneal phenotypes were assessed by slit lamp examination. The lesions were considered to be synchronic if the patients perceived the first symptoms in the second eye within a month after they appeared in the first eye. The degree of severity according to best-corrected vision was classified as: very good (>0,6), good (<=0,6 and >0,4), intermediate (<=0,4 and >0,33), and bad (<=0,33). The degree of severity according to corneal commitment was classified as follows: 1) without lesions, 2) subepithelial, white-grayish opacities, 3) refractile lattice lines, and 4) corneal edema or penetrating keratoplasty. The following abbreviations were used male (M), female (F), right eye (OD), and left eye (OS).
