AIM: To investigate the relationship between platelet parameters and macular edema(ME)in retinal vein occlusion(RVO)patients with different OCT types.METHODS: Retrospective study. A total of 126 eyes in 126 patients with RVO were enrolled in the ophthalmology department of the Fifth Affiliated Hospital of Zhengzhou University from December 2016 to February 2021, among whom, 51 eyes with central retinal vein occlusion(CRVO)were included, branch retinal vein occlusion(BRVO)included 75 eyes, 31 eyes without ME(non-ME)and 95 eyes with ME. According to the morphology of OCT, ME was divided into 26 eyes of diffuse retinal thickening(DRT), 30 eyes of cystoid macular edema(CME)and 39 eyes of serous retinal detachment(SRD), the platelet parameters of patients with different groups including platelet count(PLT), mean platelet volume(MPV), plateletcrit(PCT)and platelet distribution width(PDW)were collected and statistical analysis were performed.RESULTS:The MPV value and CMT value of ME group was higher than that of Non-ME group(all P<0.001), the MPV value of SRD group was higher than that of DRT group and CME group(all P<0.001), but there was no statistically significant difference in MPV between DRT group and CME group(P=0.526), CMT in SRD group was significantly higher than that in DRT group and CME group(P<0.001), and there was no significant difference in CMT between DRT group and CME group(P=0.190).CONCLUSION:MPV has differences in patients with RVO ME with different OCT classifications, activated platelets may be closely related to the occurrence and development of SRD.
