Purpose:The aim of this article is to determine and compare the platelet activation by three main platelet activation parameters: mean platelet volume, platelet distribution width, and plateletcrit in patients with central retinal vein occlusion and control subjects.Methods:This study included 30 patients with nonischemic central retinal vein occlusion and 30 control subjects. The levels of mean platelet volume, platelet distribution width, and plateletcrit were measured in all groups.Results:The mean serum level of mean platelet volume was 10.01 ± 0.89 fl in central retinal vein occlusion group and 8.74 ± 1.45 fl in control group. The mean serum level of platelet distribution width was 14.31 ± 1.49% and 11.65 ± 1.81% in central retinal vein occlusion group and control group, respectively. Mean serum plateletcrit value was 0.27 ± 0.07% in central retinal vein occlusion group and 0.23 ± 0.07% in control group. Mean platelet volume, platelet distribution width, and plateletcrit levels were significantly higher in central retinal vein occlusion patients than controls ( p < 0.05).Conclusion:Subclinical platelet activation reflected by mean platelet volume, platelet distribution width, and plateletcrit may have an impact on the genesis of vessel occlusion in central retinal vein occlusion. The results may be important for the clinical management of patients with central retinal vein occlusion.

Background. The aim of this study was to investigate the mean platelet volume (MPV) of patients with retinal vein occlusion (RVO).Methods. Hundred and ninty-three patients with the diagnosis of RVO and 83 healthy control subjects were included in this retrospective study. Retinal vein occlusion was diagnosed based on clinical examination. All patients and control subjects underwent complete ocular examination. MPV, hematocrit, hemoglobin, and platelet count of the participants were recorded. The data of patients with RVO was compared with the control subjects.Results. Patients with RVO had significantly higher MPV values ( fL) compared with the control subjects ( fL) (). No significant difference was found in platelet counts between RVO group and the control group ( 109/L and  109/L, resp., ), Mean platelet volume was an independent predictor of RVO (odds ratio (OR) = 1.43; 95% confidence interval (CI) = 1.09–1.89; ).Conclusion. Our results demonstrated that the MPV values were significantly higher in patients with RVO, suggesting that larger platelets may contribute to the pathogenesis of the RVOs.

Aim. To evaluate the association between mean platelet volume (MPV) and gestational diabetes mellitus (GDM). Methods. A systematic literature search was performed in PubMed, EMBASE, Web of Science, and The Cochrane Library up to 4 September 2017. Pooled standardized mean differences (SMD) and 95% confidence interval (CI) were calculated using a random-effect model. Results. Nineteen studies comprising 1361 GDM patients and 1911 normal pregnant women were included. MPV was increased in GDM patients when compared with healthy pregnant women (SMD: 0.79; 95% CI: 0.43–1.16; P<0.001). Subgroup analyses revealed that such trend was consistent in the third-trimester (SMD: 1.35; 95% CI: 0.72–1.98), Turkish (SMD: 0.81; 95% CI: 0.43–1.19), and Italian (SMD: 2.78; 95% CI: 2.22–3.34) patients with GDM and the patients diagnosed based on Carpenter and Coustan criteria (SMD: 1.04; 95% CI: 0.42–1.65). Significantly higher MPV also were observed within cross-sectional studies (SMD: 0.99; 95% CI: 0.49–1.49). Remarkable between-study heterogeneity and potential publication bias were observed in this meta-analysis; however, sensitivity analysis indicated that the results were not unduly influenced by any single study. Conclusions. GDM patients are accompanied by increased MPV, strengthening the clinical evidence that MPV may be a predictive marker for GDM.

Abstract Purpose To evaluate the association between serum vitamin B12/folate and retinal vein occlusion (RVO). Methods A comprehensive search of the PubMed database was performed, which identified 271 abstracts to be screened. Ten studies met our inclusion criteria and a meta-analysis of these comparative case-control studies was performed on the mean ± standard deviation serum vitamin B12 and folate levels, without language restrictions. Nine studies with 720 patients with RVO and 613 controls were included in the meta-analysis for vitamin B12, and 10 studies with 784 patients with RVO and 677 controls in the meta-analysis for folate. Results There was no statistically significant difference between patients with RVO and controls in serum vitamin B12 levels (mean difference: − 40.25 pg/mL, p = 0.28), either central RVO (mean difference: − 18.24 pg/mL, p = 0.71) or branch RVO (mean difference: − 23.56 pg/mL, p = 0.48). On the contrary, the plasma folate level was significantly lower in RVO patients than in controls (mean difference: − 1.34 ng/mL, p = 0.001), as well as in patients with CRVO compared to controls (mean difference: − 1.48 ng/mL, p = 0.006), but not in BRVO patients (mean difference: − 0.72 ng/mL, p = 0.11). Conclusions RVO is associated with low serum folate levels, but not with serum vitamin B12 levels.
