Macular thickness measurements in healthy eyes using spectral optical coherence tomography.
OBJECTIVE
The aim of the present study was to measure macular thickness in healthy eyes and find whether it changes with age.


METHODS
We examined 163 healthy eyes of 84 healthy volunteers. In order to measure their macular thickness the patients were examined using spectral-domain optical coherent tomography (SD-OCT - iVue, Optovue). They were allocated into 6 age groups.


RESULTS
The mean central macular thickness (inner circle - fovea centralis) was 248.9 +/- 17.9 microm (mean +/- SD), and the mean total macular thickness (an area including 9 subfields as defined by ETDRS) was 286.2 +/- 13.9 microm (mean +/- SD). We found that it correlated negatively with age (r = - 0.18; p = 0.03; Pearson correlation).


CONCLUSIONS
We found a statistically significant decrease of mean macular thickness as age increased.
