Had they read the communication more carefully, it would have become evident that the sole purpose of our study was to investigate the pathogenesis of CRVO and not the mechanism of the development of retinal hemorrhages, which are a nonspecific sign of a large variety of retinopathies. Retinal hemorrhages are seen in both entities of CRVO, ie, venous stasis retinopathy (VSR) and hemorrhagic retinopathy (HR), although they are usually far more extensive in the latter than the former; however, the extent of retinal hemorrhages is not the only criterion for diagnosing HR. I stressed that "Diagnosis of venous stasis retinopathy or hemorrhagic retinopathy is thus arrived at
