Passive permeability, active transport, and visual acuity in eyes with succesfull photocoagulation—that is, without CSMO at follow up (n = 23, responding eyes) and eyes where CSMO was still present at follow up (n = 23, non-responding eyes). For comparison, data from eyes without CSMO both at baseline and follow up (n=11) are included
