(online only supplement). Stability of low luminance deficit (LLD) over a one-year period. For eyes that had stable visual acuity over the one-year period, the LLD measure remained stable as well. Open symbols indicate eyes that lost no more than one line of ETDRS (Early Treatment Diabetic Retinopathy Study) visual acuity over one year; closed symbols indicate eyes that lost more than one line of ETDRS visual acuity over one year. The graph is divided into quadrants by lines dividing the LLD measures into worse LLD and better LLD groups.
