Change in OCT before and after sildenafil/sham. Comparison of variables before and after the ingestion of the pill for both groups. CMT: central macular thickness; CCT: central choroidal thickness; CF: choroidal flow; ORF: outer retinal flow; RVD: retinal vascular density; CVD: choroidal vascular density. ∗p < 0.01.
