Wang Q, Wei WB, Wang YX, et al. - Researchers assessed a population-based study group for the measures of the thickness of the macular retinal layers in order to appraise the normative values and their associations. The population-based Beijing Eye Study without ocular diseases and without systematic diseases, such as arterial hypertension, hyperlipidemia, diabetes mellitus, cardiovascular diseases, previous myocardial infarction, cerebral trauma, and stroke, yielded data of 384 individuals for this study (mean age:60.0 ± 8.0 years). The mean thickness of the whole retina, outer plexiform layer, outer nuclear layer,retinal pigment epithelium, inner retinal layer, and photoreceptor layer was found to be 259.8 ± 18.9 μm, 19.4 ± 3.9 μm, 93.4 ± 9.6 μm, 17.6 ± 1.9 μm, 169.8 ± 18.6 μm, and 90.0 ± 4.2 μm, respectively. The analysis revealed older age to be associated with a decrease in thickness of most retinal layers and the correlation of a higher thickness of some retinal layers with the male gender. These findings may have clinical implications and hence could be taken into account.
