Results: The results in this study revealed, statistically significant (p-value less than 0.05 %) reduction in the deep capillary plexuses density , and choriocapillaris flow area, and in FAZ flow density (FD ), statistically insignificant reduction in superficial capillary plexuses vessel density and thickness , statistically significant, with appearance of macular drusens and reduction in visual acuity and tear film. Conclusions: HCV Dual treatment (Sofosbuvir, Daclatasvir) may result in significant changes affecting retinal microvasculature and may cause eye dryness ER -
