ARMD = age-related macular degeneration; NA = not available.
Snellen visual acuity ranges for the better-seeing eye are listed below the Mild, Moderate, Severe, and Very severe groupings.
The patient values are significantly different from those of the community, clinician, and ophthalmologist groups in all categorical ARMD groupings, by one-way analysis of variance (P <.0001.)
