  1. ICF categories are reported that were coded as at least mildly impaired in more than five percent of participants, ordered by frequency (n). Results are shown for total sample and stratified by VI-category.
  2. VI = visual impairment.
  3. §1: mild difficulty, 2: moderate difficulty, 3: severe difficulty, 4: complete difficulty.
  4. #Moderate VI: BCVA 20/63 - 20/200, Severe VI: BCVA 20/200 - 1/20, High-grade VI: BCVA 1/20 - 1/50, Blindness: BCVA ≤ 1/50.
