Choroidal Thickness in Eyes with Unilateral Ocular Ischemic Syndrome

Aim. To analyze the subfoveal choroid thickness and choroidal volume in unilateral ocular ischemic syndrome (OIS).Methods. A retrospective review was conducted for all patients with unilateral OIS from October 2010 through June 2014. The subfoveal choroidal thickness (SFChT) and choroidal volume of both eyes were compared.Results. 19 unilateral OIS patients were included in this study. The mean SFChT of OIS eyes was significantly lower than that of fellow eyes (OIS eyes: 208.89 ± 82.62 μm and fellow eyes: 265.31 ± 82.77 μm,P<0.001). The choroidal volume of OIS eyes was significantly smaller than that of fellow eyes (OIS eyes: 0.16 ± 0.05 mm3and fellow eyes: 0.21 ± 0.05 mm3,P<0.001).Conclusion. The choroidal thickness and volume of OIS eyes were smaller than those of unaffected fellow eyes. Decreased choroidal circulation caused by carotid artery stenosis might affect the discordance of choroidal thickness and choroidal volume.

Ischemic Syndrome

Background. We evaluated the effect of carotid revascularization surgery on ocular circulation and chronic ocular ischemic syndrome (OIS).Methods. We examined ninety patients with carotid artery stenosis (more than 50% stenosis) at its origin treated with carotid endarterectomy (N=56) or carotid artery stenting (N=34). Twenty-five patients (28%) complained of chronic OIS. Ocular circulation was examined before and after revascularization surgery using ophthalmic artery (OphAr) and central retinal artery (CRA) color Doppler flow imaging.Results. (1) Ocular circulation: preoperatively, the average OphAr peak systolic flow velocity (Vs) was 0.05 m/sec, and the average CRA Vs was 0.07 m/sec. At 1 week after surgery, the average OphAr Vs significantly increased to 0.32 (P<0.05), and the average CRA Vs significantly increased to 0.11 m/sec (P<0.05). These significant improvements were sustained throughout the three months of the followup. (2) OIS: during the follow-up period (mean: 3.6 years), 15 patients (60%) showed visual acuity improvement, and no patients complained of amaurosis fugax or worsening of the chronic OIS.Conclusion. Carotid revascularization surgery was effective in improving the ocular circulation, and it was also useful for the chronic OIS due to the carotid artery stenosis.
