Functional Assessment - Visual Acuity
Visual acuity is a mainstay for the assessment of “How the EYE functions”. Traditional, non-logarithmic, visual acuity charts, however, are inaccurate for visual acuities worse than 20/100.

Functional Assessment - Visual Fields
Most patients are unaware of their visual field defects and scotomata, be it from AMD, from glaucoma, from RP, or from other causes. Dr. Colenbrander developed an improved functional scoring system for visual fields, as part of the Functional Vision Score system (see Guidelines)

My Vision on Vision
These short chapters summarize insights that I have gained from more than four decades working in vision rehabilitation.
