A Study on the Fundus Hemodynamics After Rhegmatogenous Retinal Detachment Operation with Colored Ultrasonic Doppler

Objective To observe the influence of different operations for patients with eyes with rhegmatogenous retinal detachment on the hemodynamics of the eye. Methods To examine the sick eyes of patients with rhegmatogenous retinal detachment before and after operations, and blood flow and the resistant index (RI) of the central retinal artery (CRA), short posterior ciliary artery (PCA) and the ophthalmic artery (OA) of the healthy eyes, the healthy eyes being in the control group. Results A comparison of the indexes of CRA, OA and PCA in both the sick eyes before the operations and the eyes in the control group found the differences among them no statistically significant. The Vmax and Vmin of the CRA and PCA of the sick eyes dropped greatly while the RI increased seven days after the operations, P0.05, the difference being significant statistically. Among them a comparison between the encircling and buckling group and the buckling group found the Vmax and Vmin of the CRA and PCA dropped even more greatly (P0.05). A comparison of the indexes of the OA blood flow between the sick eyes and healthy eyes after the operations found no noticeable difference(P0.05). Conclusions Both scleral buckling and encircling can cause the change of blood flow velocity of CRA and PCA, but the change after encircling being more notable.
