Thrombophilic tendency was not identified in any patient.Discussion: Chronic anemia, as presented in myelodysplastic syndrome’s refractory anemia subtype, probably in the presence of additional factors, such as hypotension, is likely to be complicated by optic neuropathy, possibly through a mechanism of anemic hypoxia and/or microvascular insufficiency.Keywords: myelodysplastic syndrome, anemia, optic neuropathy Dimitrios BrouzasAntonios CharakidasIoannis LadasMichael ApostolopoulosDove Medical PressarticleOphthalmologyRE1-994ENClinical Ophthalmology, Vol 2009, Iss default, Pp 133-137 (2008) |
