Abstract： Objective To measure the macular function of the fellow eye in patients with unilateral retinal vein occlusion (RVO).Methods A total of 24 cases of unilateral RVO were diagnosed by fundus fluorescein angiography (FFA),and multifocal ERG (mfERG) was recorded by RETI scan.The mfERG data of 24 fellow eyes of those RVO patients,and 18 normal control eyes were analyzed and compared.The parameters included the amplitude density,latency of the P1 and N1 wave in 6 concentric circles and 4quadrants of the mfERG graphics.Results The amplitude densities of P1 and N1 wave in first and second concentric circles of RVO fellow eyes were significantly lower than normal eyes (t=4.520,2.147;P＜0.05).There was no significant difference (P＞0.05) of P1/N1 latency in any concentric circles or quadrants between RVO fellow eyes and normal eyes.Conclusion The central fovea of the RVO fellow eyes was functionally impaired.
