Fig. 3From: Changes in choroidal thickness and optic nerve head morphology after filtering surgery: nonpenetrating deep sclerectomy versus trabeculectomyRelationships between IOP decrease and changes in subfoveolar choroidal thickness (SFCT) and mean macular choroidal thickness (MCT) 1 week after surgery. a: ΔIOP was correlated with ΔSFCT, Spearman r = − 0.41; p = 0.04. b: ΔIOP was correlated with ΔMCT, Spearman r = − 0.46; p = 0.02Back to article page
