Abstract
Objective. In this work we analyzed the current literature data about the retinal damage in cardiovascular diseases and diabetes mellitus (published from 2005 to 2020). The damage of retinal vascular bed and optic nerve represents a relevant problem in the modern world in view of the significant prevalence, severity of retinal irreversible damage leading to disability, and in relation to comorbidity with cardiovascular diseases (CVD). Methods. Publications on selected topic were analyzed from 2005 to 2020. The search was carried out using the electronic databases of the Google Academy ( https://scholar.google.com/), PubMed ( https://www.ncbi.nlm.nih.gov/pubmed/), eLIBRARY.ru (https: //www.elibrary.ru/) and foreign and national journals devoted to cardiology, therapy and ophthalmology. Results. The analysis of literature showed that atherosclerotic lesion of the microvascular retinal bed is a significant risk factor for acute coronary syndrome myocardial infarction (MI) and stroke. However, the identity of atherosclerotic processes occurring in the retinal vascular bed and in the peripheral arteries remains open. A strong association was shown between hypertensive retinopathy (HR) has with MI, congestive heart failure (CHF) and CHD mortality in large-scale population-based studies such as ARIC and Rotterdam Study. The question of the predictive significance of GR, depending on its degree, remains debatable. There are consistent evidence on the association between HR and CHD and CHF. Diabetic retinopathy (DR) represents a neurovascular complication of diabetes. In predominantly clinical work, there is evidence of the significance of DR as a risk marker for Stroke, diabetics peripheral neuropathy, autonomic cardiac neuropathy, thickness of carotid intima-media, micro albuminuria. A number of other major clinical works has not shown a significant association between DR and stroke. A significant drawback of investigation of the relationship between DR and CVD is a lack of population studies on this topic. Conclusions. Despite the use of modern diagnostic methods and a fairly large number of studies of the eye vascular bed and retina, the data about their relationship with CVD remain scare and contradictory, which is largely due to the limited size of the studied samples, the variability of the estimates, and a complexity of the pathway of atherosclerosis and CVD. The study of association between CVD and retinal pathology in the Russian population with using of automatic assessment of the microvascular bed provides a unique opportunity to solve some contradictory aspects and obtain new data. |
