Figure 8. Optical coherence tomography scan image on day 20 after laser burn and day 28 after intravitreal injection in four groups

The high reflect light echogenic mass (white arrowheads) were detected in the eyes on day 20 after laser burn and in the eye of control on day 28 after intravitreal injection. The light echogenic mass disappeared after injection compared with that before injection. The light echogenic band of retinal pigment epithelial became regular and continuous. Edema of the retina faded away and the shape of the macula fovea centralis recovered.
