Abstract: Alzheimer's disease(AD)is a progressive and irreversible neurological disease characterized by changes in neurons and blood vessels of the brain. Its etiology is unknown, and there is no feasible non-invasive technique for early diagnosis. Because the retina and the central nervous system have similar embryonic origins and physiological characteristics, an ophthalmic examination may provide a simple and non-invasive diagnostic method. Optical coherence tomography(OCT)can accurately measure the thickness of various tissue layers of the retina to assess degenerative changes of the retina. Optical coherence tomography angiography(OCTA)can provide high-resolution three-dimensional imaging, which can more directly detect the changes in retinal vessels and reflect the pathological characteristics of brain neurons and blood vessels noninvasively. This article mainly reviews the research progress of retinal thickness measured by means of OCT and retinal blood flow measured using OCTA in the diagnosis of AD.

[2] 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..

[3] 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..

[4] 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..

[5] ObjectiveTo analyze the association between the classification of blood pressure and retinal vessel diameter measured by spectral-domain optical coherence tomography(SD-OCT). MethodsThis was a cross-sectional study that included 103 patients(103 eyes)with hypertension. Based on the classification of hypertension, the subjects were divided into three groups: the isolated systolic hypertension(ISH)(34 eyes), isolated diastolic hypertension(IDH)(34 eyes), and systolic combined with diastolic hypertension(SDH)(35 eyes)groups. Retinal vessel diameters were measured by SD-OCT. The differences among the central retinal arteriolar equivalents(CRAEs), the central retinal venular equivalents(CRVEs), and the artery-to-vein ratios(AVRs)of the three groups were analyzed. Multivariate logistic regression was performed to evaluate the association between blood pressure and AVR. ResultsThere were significant differences among the CRAEs and AVRs of the three groups(F=4.543, 4.308; P=0.013, 0.016). The CRAE and AVR of the SDH group were the lowest; those of the IDH group were the highest. There were no significant differences among the CRVEs of the three groups(F=0.417, P=0.660). After correction for risk factors, such as gender and age, multivariate logistic regression showed that patients with high systolic blood pressure were more likely to have AVRs of < 0.7 (OR=1.080, P=0.015). ConclusionsAmong the three types of hypertension, SDH was associated with the lowest CRAE and AVR. High systolic pressure is a risk factor for AVRs of < 0.7..

[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..
