Visual outcomes after carotid reconstructive surgery for ocular ischemia

Effect of carotid endarterectomy on retinal function in 'asymptomatic' patients with hemodynamically significant carotid artery stenosis

“…15,16 Consequently, ICA surgery for stenosis effectively improves hemodynamic parameters both in the central retinal artery and short posterior ciliary arteries in patients with acute and chronic forms of ocular ischemic syndrome in the postoperative period. 17,18 Therefore, CEA may reduce or prevent the progression of chronic ocular ischemia and improve hypotensive retinopathy, as well as remove the risk of plaque-related embolization. Functional ocular improvement following CEA has been documented by several previous studies that have examined various parameters, including visual acuity, 18 To characterize factors that may influence the results obtained from complex ERG testing, we evaluated the potential association between the changes in full-field ERG amplitudes and several systemic risk factors and metabolic conditions.…”

Interestingly, the changes in the rod b-wave amplitudes in the EIE group were negatively correlated with the age of the participants (Rs = -0.33, P = 0.02 for EIE).…”

Relationship between the Direction of Ophthalmic Artery Blood Flow and Ocular Microcirculation before and after Carotid Artery Stenting

“…Progression of OIS can lead to an irreversible decrease in visual acuity and subsequent loss of vision, which can be prevented through early detection and intervention [4, 17]. In patients with advanced internal carotid artery (ICA) stenosis accompanying OIS, improvements in visual function after revascularization surgery have been reported [18, 19]. Improvements in ocular circulation following evaluation by ophthalmic artery Doppler waveform or fluorescent fundus angiography have also been reported [9, 18, 19].…”

Improvements in ocular circulation following evaluation by ophthalmic artery Doppler waveform or fluorescent fundus angiography have also been reported [9, 18, 19]. While ophthalmic artery Doppler waveform enables evaluation of blood flow direction and speed, there is a risk of tissue damage because of the thermal effects of the ultrasound [19].…”

Possibilities of color Duplex Imaging in the diagnosis of ocular vascular pathology

“…Допплеровские исследования кровотока в ГА, ЦАС и ЗКЦА, выполненные у 180 больных с ГИС, позволили определить значительное увеличение скорости кровотока и снижение вазорезистентности в орбитальных сосудах после реконструктивных операций на ВСА в отдаленном послеоперационном периоде (рис. 7) [1,45,46]. У наблюдаемых нами пациентов с острым и хроническим типом течения ГИС в послеоперационном периоде зафиксировано повышение Vsyst, снижение RI в ГА, ЦАС и ЗКЦА (см.…”
