Purpose:

To determine reproducibility and repeatability of macular thickness measurements before and after pupillary dilatation using spectral domain (SD) OCT.

Methods:

Forty four eyes of 44 subjects with normal ocular examination underwent macular thickness measurement. The 512×218 scan pattern of Cirrus SD-OCT was used for data acquisition and analysis. For each case, 6 scans (3 before and 3 after pupillary dilatation) were performed by the same operator.

Results:

Overall, macular thickness measurement was highly repeatable and reproducible; with ICC of 0.95 (95% CI 0.95-0.99). Mean macular thickness pre and post pupillary dilation showed significant change in outer nasal (3 to 6 mm to macular center=N2) and outer inferior (3 to 6 mm to macular center=I2) sectors (p = 0.001). The most repeatability before dilatation was at inner nasal sector (1 to 3 mm to macular center=N1) and after dilatation was at central subfoveal sector(C).

Conclusion:

Cirrus SD-OCT showed a high level of repeatability and reproducibility in measuring macular thickness in healthy eyes. Regarding to the significant changes in N2 and I2 sectors in mean macular thickness measurement pre and post pupillary dilation, it seems reasonable to choose only one method (using mydriatic or not) for monitoring outer macular sectors thickness in follow up of a case.
