To investigate the relationship between the choroidal thickness and choroidal blood flow in healthy young subjects.
Retrospective study. 25 eyes of 25 healthy young Japanese subjects were examined. The subfoveal choroidal thickness was measured by enhanced depth imaging optical coherence tomography (EDI OCT). Total choroidal blood flow and suoveal choroidal blood flow were evaluated by pulsatile ocular blood flow (POBF) using Langham OBF computerized tonometry and choroidal blood flow (CBF) value using laser Doppler flowmetry respectively. The refractive error, intra ocular pressure and axial length were also measured.
The subfoveal thickness was positively significantcorrelated with the refractive error and negatively correlated with axial length. There was no significant correlation between subfoveal choroidal thickness and both POBF and CBF.
Although the decrease in subfoveal choroidal thickness was associated with decrease of refractive error and axial length, subfoveal choroidal thickness have no correlation with both total choroidal blood flow and subfoveal choroidal blood flow in healthy young subjects.
