Evaluation of myopia on retinal nerve fiber layer thickness measured by Spectralis optical coherence tomography.

The aim of the present study was to evaluate the retinal nerve fiber layer (RNFL) thickness of myopic subjects using Spectralis optical coherence tomography (OCT) and to determine variations with age and sex. A total of 271 Chinese participants with a spherical equivalent <+0.50 diopters were enrolled in the research. All subjects underwent a full ophthalmic examination. RNFL thickness was measured and compared according to sex, age and spherical equivalent. No significant difference was demonstrated between RNFL thickness in males and females. No significant difference was observed between RNFL thickness of the two age groups (<= 12 years old and >12 years old). Significant differences were observed in all subfields of RNFL thickness among different spherical equivalent groups (P<0.05). In conclusion, myopia did have special influence on RNFL thickness, which was not related to sex or age.
