Grassi et al2 described atypical pigment dispersion in an 8-year-old boy. We describe an 11-year-old girl with bilateral PDS with elevated intraocular pressure (IOP) as well as two 12-year-old boys, one with a more severe phenotype and both parents affected (suggesting the probability of homozygosity or inheritance of a predisposing gene from each parent) and the other with a less severe phenotype and 1 parent affected (showing the . . .
