Asymmetry parameters identify early primary open-angle glaucoma
Asymmetry parameters can be useful in identifying early primary open-angle glaucoma, according to a study. The prospective, cross-sectional cohort study included both eyes of 50 patients with early primary open-angle glaucoma and 50 control subjects. All eyes underwent measurements of macular thickness and retinal nerve fiber layer thickness (RNFL) using spectral-domain optical coherence tomography (Spectralis, Heidelberg Engineering). The study authors reported that intereye macular thickness asymmetry showed the highest diagnostic sensitivity (88% at 80% specificity; 83% at 95% specificity), succeeded by total RNFL thickness (88% at 80% specificity; 75% at 95% (Read more...)
