Korean normative database for time domain optical coherence tomography to detect localized retinal nerve fiber layer defects (preliminary study).
OBJECTIVE
To establish a Korean normative database of retinal nerve fiber layer (RNFL) thickness.


METHODS
Data was collected from 103 healthy volunteers. Total ophthalmologic examinations, including fast RNFL thickness analysis by time domain optical coherence tomography (STRATUS OCT) were performed. The RNFL thickness of 64 glaucoma patients with localized RNFL defects and 48 independent healthy subjects were collected. The RNFL thickness of both the glaucoma patients and the healthy subjects was evaluated using both normative databases.


RESULTS
The average RNFL thickness of Koreans was 108.3 +/- 10.3 microm. The sensitivity rates recorded in the Korean normative database with 5% and 1% significance were 0.984 and 0.984, with specificity values of 0.938 and 1.000. By comparison, the sensitivity rates in the conventional normative database with 5% and 1% significance are 0.984 and 0.953, and the specificity values are 1.000 and 1.000.


CONCLUSIONS
In detecting localized RNFL defects, the Korean database showed higher sensitivity than the conventional database.
