Hashmani N, et al. - Experts quantified and viewed the possible impact of demographic variables on normal macular layers. They also evaluated the reproducibility using the Spectralis SD-OCT. Various retinal layers were seen to be different according to age, gender, and axial length. Moreover, excellent reproducibility of this algorithm using the Spectralis SD-OCT was demonstrated. There was a decrease in the age with ganglion cell layer (GCL), inner plexiform layer (IPL), inner retinal layer (IRL), photoreceptor layer (PL), and total retinal thickness (TRT). There was an inverse relationship between the inner nuclear layer (INL), outer nuclear layer (ONL), and retinal pigment epithelium (RPE) and axial length.
