Abstract:
Objective To investigate the macular vascular density after successful repair of rhegmatogenous retinal detachment (RRD) for one year using optical coherence tomography angiography (OCTA),and discuss the correlation between the macular vascular density and visual acuity.Methods Totally 42 patients of the RRD (42 eyes),their contralateral eyes (A group) and 42 patients of the normal eyes (B group) were recruited into this study.All participants underwent examination with best corrected visual acuity (BCVA) and OCTA.The difference in macular vascular density was compared and the correlation between BCVA and the vascular density was analyzed.Results The macular vascular density of superficial layer,deep layer and choroidal capillary layer was 0.422 4 ±0.089 3,0.4836 ±0.0748,0.527 1 ±0.039 0 in RRD group,respectively,0.469 3 ±0.112 5,0.550 0 ±0.074 0,0.546 2 ±0.034 3 in A group,respectively,0.5619 ±0.053 7,0.611 2 ±0.035 2,0.562 6 ±0.030 4 in B group,respectively.The macular vascular density was significantly decreased in RRD group when compared with A and B groups (all P ＜ 0.05).There was a positive correlation between BCVA and the macular vascular density in the deep layer and choroidal capillaries layer (r =0.629,0.654,both P =0.000).However,there's no correlation between the macular vascular density of superficial layer and BCVA (P =0.103).Conclusion All the macular vascular densities are decreased in patients of RRD after successful repair of retinal detachment one year later,which indicated that the blood flow does not completely recover.And there is a positive correlation between BCVA and macular vascular densities in deep layer and choroidal capillaries layer.And meanwhile,OCTA can objectively and effectively quantify the status of macular region blood flow.
