Evaluation of Subfoveal Choroidal Thickness in Internal Carotid Artery Stenosis

Table 2

Subfoveal choroidal thickness and other clinical measurements in both groups.

	Group 1	Group 2	value
SFCT, mean ± SD	231.9 ± 44.6	216.2 ± 46.8
Percentage of ICA stenosis (%), mean ± SD	74 ± 4.9 (70–85)	47.5 ± 7.7 (35–60)
PSV (cm/sec), mean ± SD	235.53 ± 7.8	118.95 ± 16.1
Refractive error [mean ± SD (diopters)]	−0.27 ± 1.6	−0.34 ± 1.8
IOP mmHg [mean ± SD, (range)]	15.2 ± 1.1 (12–18)	14.9 ± 18 (11–17)
OPP mmHg [mean ± SD, (range)]	41.8 ± 1.6	40.9 ± 1.3

ICA: internal carotid artery; SFCT: subfoveal choroidal thickness; PSV: peak systolic velocity; OPP: ocular perfusion pressure; IOP: intraocular pressure; and SD, standard deviation; value of less than 0.05 was considered to be significant.
