Evaluation of Optical Coherence Tomography–Angiography Findings in Keratoconus Patients Treated With Accelerated Cross-linking Protocol

In keratoconic eyes successfully treated with A-CXL, significant changes in the vascular density of both the superficial and deep retinal plexuses were observed in the early postoperative period. Although alterations in the superficial plexus seemed to be mostly reversible, sustained changes in deep retinal microcirculation and perfusion parameters suggest a more prolonged and possibly subclinical effect of A-CXL on the outer retina.
