GSTM1 and Retinal hemorrhage: Consistent with our findings Jihene Sayadi et.al [22], .have illustrated that retinal hemorrhages were significantly associated with lower Hb concentrations (P 0.038) and thrombocytopenia (P0.035), however, in our study we did not find a significant association between retinal hemorrhage and thrombocytopenia or leukocytosis (P 0.283and 0.38, respectively) in contrast to conclusions delivered by Malaysian study showing that leukocytosis and thrombocytopenia were significantly associated with retinal hemorrhages in AML patients [23].
