Effects of hemoglobin concentration on retinochoroidal vascular plexuses: an optical coherence tomography angiography study.

In this study, quantitative OCTA analysis revealed a higher tendency for retinal and choroidal microvascular morphological changes in patients with anemia and PV. The outcomes of the current investigation can provide new insights into the retinal and choroidal pathophysiologies found in patients with hemoglobin abnormalities.
