This healthy 16YO female presented with 2 days of acute bilateral vision loss. She denied any trauma or Valsalva. Vision was 20/400 OU.
Color photography shows extensive bilateral preretinal and sub-internal limiting membrane hemorrhages. Some intraretinal white-centered hemorrhages are also noted. She was found to have profound iron-deficiency anemia due to very heavy menstruation with a hemoglobin of 5.2 gm/dl.
The blood was improving bilaterally two weeks later. Following multiple blood transfusions, the posterior segment hemorrhages spontaneously resolved (not shown).
