Abstract:
Objective To investigate the characteristics of multifocal electroretinogram (mf-ERG) and optical coherence tomography (OCT) in macular edema (ME) secondary to retinal vein occlusion (RVO).Methods Mf-ERG and OCT were performed in 38 patients (38 eyes) of ME secondary from RVO patients and 23 normal persons (23 eyes) in the same period of the control group.OCT was used to detect macular retinal thickness (CMT) at foveal area with diameter 1 mm,mf-ERG was used to evaluate the function of macular retina and analyze the amplitude density of P1 wave and latency of P1,N1 wave from ring 1 to ring 5.Results Compared with the control group,the amplitude densities of P1 in BRVO group were obviously decreased in ring 2 (35.95 ± 17.04)nV · deg-2,ring 3(24.72 ±8.32)nV · deg-2,ring 4(19.28 ±6.38)nV ·deg-2,ring 5 (13.49-± 6.16) nV · deg-2,respectively (all P ＜ 0.05);The latencies of P1 were prolonged significantly in ring 2 (35.74-± 3.72) ms (P ＜ 0.05);The latencies of N1 were prolonged significantly in ring 2 (18.43-± 4.63) ms,ring 3 (18.67-± 2.86) ms (both P ＜ 0.05).Compared with the control group,the amplitude densities of P1 in CRVO group were obviously decreased in ring 1 (81.58 ± 43.15) nV · deg-2,ring 2 (33.71 ±9.81) nV · deg-2,ring 3 (22.15 ± 9.75) nV · deg-2,ring 4 (16.65-± 6.38) nV · deg-2,ring 5 (14.18-± 4.59) nV · deg-2,respectively (all P ＜ 0.05);The latencies of P1 were prolonged significantly in ring 2 (37.56 ± 5.55) ms,ring 3 (37.31 ± 5.22) ms,ring 4 (35.71 ±5.63) ms,ring 5 (37.30 ± 5.37) ms (all P ＜ 0.05);The latencies of N1 were prolonged significantly in ring 1 (21.82 ±5.76) ms,ring 2(19.18 ±4.82) ms,ring3 (19.31 ±4.25)ms,ring 4 (19.05 ± 4.55) ms,ring 5 (19.43 ± 4.12) ms (all P ＜ 0.05).There was negative correlation between CMT and amplitude densities of P1 of ring 1 in CRVO group (r =-0.576,P ＜ 0.05).Conclusion OCT combined with mf-ERG can comprehensively reflect the change of retinal fumction and structure in ME secondary to RVO.
