Visual acuity outcome between initial and post-observation/treatment assessment at individual level (154 evaluable eyes in 77 patients). Visual acuity outcome per eye for patients in (A) observation only, (B) treatment at diagnosis, (C) treatment after observation, and (D) summary of visual acuity outcome of all 77 patients. CF: count fingers, HM: hand movement, LP: light perception; NLP: no light perception. *“Improvement”/ “worsening” was defined as a 2-line change in VA, or decrease from LogMAR < 1·6 to shaded area, ie, CF, HM, LP, or NLP.
