Chang TC, et al. - Researchers gauged the early clinical factors related to poor long-term visual, and intraocular pressure (IOP) control outcomes in early-onset glaucoma as the initial steps to constructing a severity staging system. Poor final visual outcome were predicted by the presence of nystagmus, anterior segment dysgenesis (ASD) or failed angle surgery early in the course of infantile-onset glaucoma management, whereas poor final IOP control was predicted by failed angle surgery and presence of media opacity (MO). In constructing a severity staging system, these predictors of poor outcomes will serve as the initial steps.
