Abstract: The vessels of eye and brain have close anatomical connections and similar physiological characteristics. Ocular ischemic syndrome(OIS)is an ischemic eye disease related to carotid artery stenosis, and ischemic stroke is the most representative ischemic cerebrovascular disease. Several studies have shown that OIS-related signs have some predictive value for the occurrence of ischemic stroke. Conversely, various ocular ischemic changes have been found to be secondary to ischemic stroke. This article reviews the findings on the association between OIS and ischemic stroke to promote multidisciplinary cooperation and optimize clinical diagnosis and treatment strategies.

Key words: Ocular ischemic syndrome, Ischemic stroke, Carotid artery stenosis, Hemodynamics, Vascular endothelial growth factor

[3] Ocular ischemic syndrome(OIS)is a severe ophthalmic disease caused by ocular hypoperfusion, which occurs due to stenosis or occlusion of the common or internal carotid arteries. The clinical presentations and signs of OIS are complex, incidental, and different. OIS is easily misdiagnosed or remains undiagnosed because of its asymptomatic onset and complicated ocular manifestations. Therefore, it is crucial to trace the etiology of OIS. Presently, different imaging modalities can evaluate the carotid artery blood supply, collateral circulation, and brain perfusion. Thus, appropriate modalities must be selected for OIS diagnosis based on their advantages and disadvantages. Furthermore, the auxiliary examination results should be accurately and promptly considered and interpreted when establishing a diagnosis of OIS. Thus, the management of OIS requires cooperation with ophthalmologists, cardiologists, and neurologists..

[4] Carotid artery stenosis is a common clinical disorder. Its main clinical symptoms are transient ischemic attacks and cerebral infarction, ocular ischemic syndrome(OIS)is rare. Its diagnostic imaging modalities include doppler ultrasound imaging, CTA, and MRA. Medical therapy, including risk factor management of atherosclerosis, is necessary for all patients with carotid artery stenosis. Carotid revascularization techniques, including carotid endarterectomy or carotid artery stenting, should be performed for asymptomatic patients with severe carotid artery stenosis and symptomatic patients with moderate carotid stenosis. Patients with carotid artery stenosis need early interventions to prevent stroke, improve ocular artery perfusion, and, ultimately, prevent further vision loss..

[5] Ocular ischemic syndrome(OIS)is usually undiagnosed or misdiagnosed due to its asymptomatic onset, complicated ocular manifestations, and the lack of awareness, and patients with OIS have a higher mortality. Improving the understanding, diagnosis, and treatment of OIS through multidisciplinary collaboration is key to investigating and preventing systemic vascular events as well as decreasing blindness and mortality. This review summarizes the recent advances in the epidemiology, clinical diagnosis, and management of OIS..

[6] ObjectiveObjectiveTo analyze the literature on ocular ischemic syndrome published between January , and December , . MethodPapers on OIS that were published between January , and December , , were screened and retrieved from the CNKI and WOS databases, and those that were relevant were searched and analyzed. ResultsIn this analysis, Chinese papers on OIS were cited for times with an h-index of , while foreign papers were cited for times with an h-index of . Of the organizations that published the highest number of papers and had the highest h-indexes, the Capital Medical University and the Polish Medical University of Pomerania were the leading institutions. The Chinese Journal of Ophthalmology was the leading domestic journal, and the Journal of Ophthalmology and Plos One were the leading foreign journals. China published the highest number of papers abroad, China and South Korea had the highest h-indexes. China′s National Natural Science Foundation provided the most support to the field of OIS, accounting for .% of the total domestic literature. The most frequently cited article in the WOS database was by Hayreh, SS, which was on the prevalence and pathogenesis of ocular vascular occlusive disease and melanosis, it was also part of the top ten studies that focused on the utility of OCT in providing insights into OIS and the mechanisms of ischemia and hypoxia. ConclusionThe utility of OCT in providing insights into OIS and the mechanisms of hypoxia and ischemia represents a modern focus of researchers..

[7] ObjectiveTo discuss the causes and appropriate treatment for iris neovascularization following the analysis of cases( eyes). MethodsIt was a retrospective case series study involving patients( eyes)with iris neovascularization diagnosed between September and July . All the patients underwent ophthalmic examination, and all the examination findings and treatments were recorded. The causes, correlative factors, and treatment outcomes of iris neovascularization were analyzed. ResultsOf the patients, ( eyes, .%)had retinal ischemic signs, including vitreous hemorrhage and retinal vascularization on fundus fluorescein angiography, ( eyes, .%)did not have retinal ischemic signs. After months of treatment, retinal vascularization resolved in all the cases, and iris neovascularization resolved completely in patients( eyes, .%), iris neovascularization was still found in patients( eyes, .%). ConclusionsAnterior segment ischemia may also lead to iris vascularization, although retinal ischemia was the main cause. Additionally, iris neovascularization may not always resolve with treatment for retinal ischemia. Finally, anti-VEGF drug injection was an effective treatment for iris neovascularization..

[8] ObjectiveTo discuss the early diagnosis and multidisciplinary diagnosis and treatment of neovascular glaucoma in ocular ischemic syndrome. MethodsThe medical records of a 54-year-old male patient with cerebral infarction who presented with right-eye vision loss that had persisted for a week were reviewed. After slit-lamp examination and fluorescence angiography, he was diagnosed with ocular ischemic syndrome(OIS)complicated by neovascular glaucoma in the right eye and treated with intravitreal injection of anti-VEGF drugs and panretinal photocoagulation. ResultsAfter three months of treatment, the right-eye iris neovascularization subsided, and the intraocular pressure was controlled within normal limits. ConclusionOcular ischemia is often missed or misdiagnosed by ophthalmologists, neurologists, cardiologists, and vascular surgeons due to its insidious onset and complex clinical manifestations. Therefore, the establishment of multidisciplinary diagnosis and treatment can improve the prognosis of OIS patients..

[9] Spectral-domain optical coherence tomography(SD-OCT)was used to measure and observe the characteristics of the subfoveal choroidal thickness(SFCT)in patients with ocular ischemic syndrome(OIS)as well as explore the indicators for early evaluation of OIS. MethodsThis was a retrospective case-control study. Forty-eight patients(48 eyes)were included between January 2017 and January 2020. The patients were divided into two groups: the OIS and the control groups, with each consisting of 24 patients(24 eyes). Their basic information, including age, gender, body mass index(BMI), and the history of diabetes, hypertension, and hyperlipidemia, was collected. SFCT was measured using SD-OCT in EDI mode. The basic data and SFCTs of the two groups were compared. ResultsThere were no significant differences between the ages, gender, BMIs, and the prevalence of diabetes, hypertension, and hyperlipidemia of the two groups(all P>0.05). The mean SFCT of the OIS group was 204.83±27.34 μm, and that of the control group was 226.58±33.49 μm. The differences between the two groups were statistically significant(t=2.464, P=0.018). ConclusionsSFCT was thinner in patients with OIS. SFCT can be used as an indicator for early assessment of OIS..
