Changes in Retinal and Choroidal Vascular Blood Flow after Oral Sildenafil: An Optical Coherence Tomography Angiography Study

Table 1

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. .
