Macular and peripapillary spectral domain optical coherence tomography changes in sickle cell retinopathy.

Purpose: To assess peripapillary retinal nerve fiber layer, macular ganglion cell complex, and total macular thicknesses using spectral domain optical coherence tomography on sickle cell disease patients with and without sickle retinopathy.

Method: Nineteen eyes of 11 patients with hemoglobin sickle cell disease, 65 eyes of 36 patients with hemoglobin SS disease, and 48 eyes of 24 healthy subjects underwent spectral domain optical coherence tomography scanning (RTVue). Eyes of patients with sickle cell disease were classified into 3 groups according to posterior segment changes: no retinopathy (n = 64), nonproliferative retinopathy (n = 12), and proliferative retinopathy (n = 8).
