With the development of medical technology, in clinic, other disease signs can be seen through eye diseases, especially the risk and prognosis of some cardiovascular diseases.
The artery blocked and one eye suddenly went blind
The arteries of patients with hypertension become thinner and the blood flow is relatively slow; The arterial endothelium is damaged, and the inner wall of the blood vessel is rough and narrow, which is easy to form thrombus. Once the thrombus blocks the artery, the patient’s eyes will suddenly be invisible. Our retina depends on the central artery for blood supply. If the artery is blocked, it will lead to retinal ischemia and hypoxia. The disease is more common in patients with hypertension and arteriosclerosis, mainly in the elderly with cardiovascular disease, and occasionally in young patients. 90 minutes is the golden time to rescue patients with central retinal artery occlusion. More than 90 minutes, irreversible damage often occurs to retinal nerve tissue. Therefore, if the patient suddenly can’t see anything, and there is only light feeling or no light feeling, he should see a doctor in time to avoid delaying treatment and permanent loss of vision.
Hypertension changes fundus
Human retina is very sensitive. It is the only tissue in the whole body that can directly and noninvasively observe blood vessels and systemic microcirculation. Any change in retina can reflect the health status of other parts of the body. The heart load can be distinguished from the blood distribution and congestion of the eyes; The degree of fundus lesions is sufficient to reflect the progress of hypertension. In other words, the more serious the fundus changes, the longer the duration of hypertension and the more serious the condition. It is suggested that patients with hypertension must follow the doctor’s advice and insist on taking medicine. In case of vision loss, they should see a doctor as soon as possible, and check the fundus every 3-6 months.
Decreased vision and increased risk of death
With the popularity of electronic products, the incidence rate of eyesight decrease has increased significantly, and there is a trend of younger age. In the past, it was thought that impaired vision would mainly bring inconvenience to life, but a recent study published in the European Journal of preventive cardiology showed that impaired vision would significantly increase the risk of cardiovascular death. About 580000 subjects with an average age of 39.7 years were included in the study. The subjects were divided into four groups according to the side of the eye with better vision: normal group, vision reduction group, mild vision impairment group and moderate and severe vision impairment group. After 8.1 years of follow-up, 6585 people died, of which 974 died of cardiovascular disease. After adjusting for all suspicious factors, compared with the normal visual acuity group, the all-cause mortality increased by 21%, 26% and 54%, and the cardiovascular mortality increased by 32%, 43% and 141%, respectively. The person in charge of the study believes that for people with impaired vision, we should not only treat ophthalmic diseases, but also actively investigate cardiovascular diseases and strengthen preventive measures.
Xanthoma of eyelid, dyslipidemia
This “tumor” is actually an orange rash, which often occurs on the inner canthus of the eyelid, progresses slowly and rarely heals itself. Eyelid xanthoma is more common in middle-aged and elderly women, especially in obese women with less activity and excess nutrition. Excessive lipids will deposit in a certain part of the body. After they are swallowed by cells, they form flakes of various shapes. Eyelid xanthoma is a common one. If the middle-aged and elderly people find that they have eyelid xanthoma in their eyes, they should go to the hospital to check their blood lipids as soon as possible.
The edge of the black eyeball is gray and the blood vessels become hard
Fat will accumulate around the cornea and cover the front of the eye. This disease called corneal ring is common in middle-aged and elderly people, marked by a gray white ring at the edge of the cornea. Corneal ring appears in middle-aged and elderly people, which is generally not painful or itchy, and vision will not decline, so it is easy to be ignored. Therefore, remind middle-aged and elderly friends that they might as well look at their eyes in a mirror at ordinary times. If the corneal ring appears at the edge of the black eye, they should ask the doctor to check whether they have hyperlipidemia and atherosclerosis as soon as possible.
