ABSTRACT
Objective: To observe the prognosis of RRDCD after vitrectomy using OCTA.
Methods: We gathered information of three groups including RRDCD group, RRD group and normal control group respectively whose superficial and deep retinal VD, FAZ, FT and SFCT were detected via OCTA. Afterwards, chi-square test, independent sample T-test and least significant difference (LSD) method were used as the statistical analysis method for the collected data to compare the RRDCD with RRD and normal control groups.
Results: The patients of RRDCD group had comparatively lower VD of superficial and deep retinal layer in both 3 × 3 and 6 × 6 mode. There was no difference in FAZ and FT, but existed differences in SFCT between these three groups. Furthermore, correlation analysis showed that there were positive correlations between postoperative BCVA and SFCT (r = 0.366, P = 0.026), BCVA and VD of deep retinal layer in 6 × 6 mode (r = 0.315, P = 0.048) in RRDCD group.
Conclusion: There was a remarkable reduction of VD in postoperative RRDCD which can be evaluated by OCTA effectively.
