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.

| [1] | 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..

| [2] | 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..

| [3] | ObjectiveObjectiveTo analyze the literature on ocular ischemic syndrome published between January 1, 2014 and December 31, 2019. MethodPapers on OIS that were published between January 1, 2014 and December 31, 2019, were screened and retrieved from the CNKI and WOS databases, and those that were relevant were searched and analyzed. ResultsIn this analysis, 35 Chinese papers on OIS were cited for 41 times with an h-index of 2, while 48 foreign papers were cited for 115 times with an h-index of 6. 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 20.8% 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..

| [4] | 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..

| [5] | 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..

| [6] | To evaluate the changes in the parameters of the macular and peripapillary vasculature in patients with neuromyelitis optica spectrum disorder(NMOSD). MethodsThis case-control study involved 40(76 eyes)aquaporin-4 antibody-positive NMOSD patients and 40(80 eyes)age- and gender-matched healthy controls(HCs). Of 76 eyes with NMOSD, 34 had a history of optic neuritis(ON); 40 had no history of ON. Macular superficial vessel density(MSVD), macular deep vessel density(MDVD), and radial peripapillary capillary(RPC)density were measured by OCT-A. The retinal nerve fiber layer(RNFL)and ganglion cell complex(GCC)thicknesses were measured by OCT. Comparisons of the retinal structural and microvascular parameters of the cohorts were performed using generalized estimating equation(GEE)models. The relationship between retinal vessel density and retinal thickness was also analyzed. ResultsRPC density and MSVD were significantly lower in eyes with NMOSD+ON than in those with NMOSD-ON and HC(P<0.05). The GCC and RNFL thicknesses were also significantly thinner in eyes with NMOSD+ON than in those with NMOSD-ON and HC(P<0.001 for both). MDVD was lower in eyes with NMOSD-ON than in those with HC(P<0.05); however, other vessel densities were not significantly different(P>0.05). In eyes with NMOSD, MSVD, whole image vessel density(WIVD)of RPC, and peripapillary vessel density(PPVD)were correlated with GCC and RNFL thicknesses(P<0.001). However, MDVD and inside disc vessel density(IDVD)were not correlated with GCC and RNFL thicknesses(P>0.05). ConclusionRetinal microvascular changes were present in eyes with NMOSD+ON. However, these changes, except those in MDVD, were not significant in eyes with NMOSD-ON. Thinner GCC and RNFL were associated with lower MSVD and RPC density..
