Changes in Retinal Vasculature and Thickness after Small Incision Lenticule Extraction with Optical Coherence Tomography Angiography

Figure 2

Optic coherence tomographic angiogram of the macular area from a 24-year-old female. The superficial vessel density at the fovea, parafovea, and perifovea was 16.3%, 55.4%, and 51.9% before surgery (a). The superficial vessel density at the fovea, parafovea, and perifovea was 12.2%, 43.5%, and 41.9% at 1 day postoperatively (b). The superficial vessel density at the fovea, parafovea, and perifovea was 14%, 51.3%, and 47.9% at 2 weeks postoperatively (c). The deep vessel density at the fovea, parafovea, and perifovea was 28%, 56.5%, and 51.3% preoperatively (d). The deep vessel density at the fovea, parafovea, and perifovea was 26%, 54%, and 42.3% at 1 day postoperatively (e). The deep vessel density at the fovea, parafovea, and perifovea was 26.4%, 54.1%, and 45.7% at 2 weeks postoperatively (f).
