Fig. 2. ChT at each location at baseline and last examination. (A) Avg ChT shows significant thinning. (B) Avg ChT shows a tendency toward recovery. (C) There is no significant change in ChT. (D) There is no significant change in ChT. Error bars indicate standard deviation. HCQ = hydroxychloroquine; ChT = choroidal thickness; SubF = subfovea; Avg = average. *Statistically significant p-values.
