Mean platelet volume in patients with retinopathy of prematurity

Abstract

Objective: We aimed to evaluate the mean platelet volume (MPV) in patients with retinopathy of prematurity (ROP) with respect to development of type 1 ROP Methods: The medical records of the premature infants were evaluated. Babies with a birth weight under 1500 g and a gestational age under 32 weeks were enrolled to the study. Birth weight, gestational age, onset and grade of retinopathy, presence of plus disease were analyzed. At the time of type 1 ROP diagnosis, blood samples were obtained. In the patients without type 1 ROP the blood samples were also obtained at similar gestational age. Hemoglobin, hematocrit, platelet count, and MPV results were recorded. Results: Sixty-three infants were studied. 22 of them had type 1 ROP and 41 had not developed type 1 ROP. The mean gestational age and the mean birth weight between groups were not statistically significant. The mean MPV values in patients with type 1 ROP and without type 1 ROP was 9,1p2,0 fL and 9,4p1,8 fL, respectively (p=0.61). Conclusion: The results demonstrated that MPV values were not associated with severity of ROP in our study population. J Clin Exp Invest 2014; 5 (2): 443-446
