![]() ![]() Rates of age-related decline were 2.3%, 2.0%, 1.7%, 3.3%, and 4.3% per decade for RNFL, RT, RV, MDB neuroretinal rim thickness, and MDB area, respectively. Results: There were 272 normal subjects, including 175 whites, 40 blacks, 40 Asians, and 17 Hispanics. Custom-designed software calculated neuroretinal rim minimum distance band (MDB) thickness and area. The SD-OCT software calculated peripapillary RNFL thickness, retinal thickness (RT), and retinal volume (RV). All patients received retinal nerve fiber layer (RNFL) scans and an optic nerve 3D volume scan. Methods: This is a cross-sectional study performed at a single institution in Boston. Purpose: To evaluate the effects of age, race, and ethnicity on the optic nerve and peripapillary retina using spectral-domain optical coherence tomography (SD-OCT) three-dimensional (3D) volume scans in normal subjects. ![]()
