Iron deficiency anemia presenting with central retinal vein occlusion and stellate figure in the macula

An 18-year-old woman complaining of visual disturbance in her left eye was referred to our hospital. The bestcorrected visual acuity (BCVA) in the left eye was 0.6. Fundus examination revealed tortuous retinal veins and macular edema with stellate figure. Optical coherence tomography (OCT) showed that the macular thickness was increased to 539 μm. In addition, hyper-reflective substances were detected in the Henle fiber layer. On laboratory findings, she had iron deficiency anemia (IDA). Therefore, we diagnosed the condition as a central retinal vein occlusion (CRVO) caused by IDA. Systemic administration of elemental iron was initiated. The BCVA improved to 1.2, the macular edema dramatically resolved, and the macular thickness was reduced to 219 μm 1 month later. Changes in microstructural findings and visual acuity were analogous during recovery of macular edema in our patient. We should be aware of IDA for young female presented CRVO.
