Purpose:
To evaluate the changes in the peripapillary choroidal vascularity index (PCVI) and subfoveal choroidal vascularity index (SFCVI) in multiple sclerosis (MS) patients and healthy subjects.
Methods:
A total of 145 eyes of 73 patients were investigated in this cross-sectional study. 78 eyes of 39 MS patients (Group 1) and 67 eyes of 34 healthy subjects (Group 2) were evaluated. MS patients with a history of optic neuritis (ON) constituted Group 1a, those without a history of ON constituted Group 1b.
Results:
The mean PCVI was significantly lower in Group 1 than Group 2 (61,39 ± 3,00% vs 64,49 ± 2,29%, respectively, p < 0.001). The mean SFCVI scores of Group 1 was significantly lower than Group 2 (64,01 ± 2,66% vs. 66,87 ± 2,14%, respectively, p < 0.001). The mean PCVI of Group 1a (59,26 ± 2,85%) was significantly lower compared to Group 1b (62,87 ± 2,08%) and Group 2 (64,49 ± 2,29%, p1 < 0.001, p2 < 0.001). The mean SFCVI of Group 1a was significantly lower than Group 2 (64.26 ± 2.75% vs. 66.87 ± 2.14%, respectively, p < 0.001).
Conclusion:
PCVI and SFCVI scores were significantly lower in MS patients compared to healthy controls. PCVI scores of MS patients who had a history of ON were significantly lower than those of patients without a previous ON attack, as were SFCVI scores. We consider that evaluation of PCVI and SFCVI might be useful for monitoring ocular involvement in patients with MS.
