Netizen asks: what is the reason that eyesight drops suddenly? I'd like to know some information about this. Please help me with it. Thank you very much. What are the reasons for sudden decline in vision?
Expert: it seems to be a very common phenomenon for old people to be dazzled, so it's normal for almost all old people to feel that they can't see clearly. However, it must be reminded that if the elderly suddenly cannot see things in the distance, they should go to the hospital immediately, because it is likely to be a sign of some diseases.
Acute angle closure glaucoma: more common in the elderly over 50 years old, more common in women, serious cases can lead to blindness in a short time. It has a family genetic tendency. Anger, fatigue and sudden climate change are common inducing factors. In addition to the sudden loss of vision, this disease is accompanied by eye pain, headache, nausea and vomiting. When you look at the incandescent bulb, you will feel that there are colored rings around the bulb.
Central retinal artery embolism: many elderly people have atherosclerotic problems, such as the shedding of atherosclerotic plaque on the inner wall of the artery, which will lead to central retinal artery embolism, retinal ischemic necrosis, and loss of visual function. The typical feature of this disease is a sudden painless complete blindness in one eye, and some patients will have paroxysmal and transient blackness before the attack. It is more common in the old people with hypertension, arteriosclerosis and cardiac insufficiency. If not treated in time, they may be completely blind due to retinal tissue necrosis.
Vitreous hemorrhage: it often occurs in the old people with hypertension and diabetes, and it can also occur in some patients with fundus vascular diseases. Bleeding usually comes from new blood vessels or fundus vascular damage, blood into the vitreous cavity to block light into the eye, will lead to visual loss. In addition to blurred vision, there were also black shadows floating in front of the eyes when there was less blood; When there is a lot of hematocele, the vision decreases sharply and only light perception remains.
Causes of sudden decline in visual acuity 4. Optic papilla ischemia: due to the hardening of the blood vessels supplying the optic papilla, the optic nerve in the corresponding blood supply area is ischemic, and the optic papilla is degenerative, so the vision is suddenly blurred, and there is a fixed blind area in front of the eyes, that is, the loss of visual field.
Retinal detachment: more common in the elderly, most of them have myopia, some people have eye disease. Age, heredity and trauma are the inducing factors. When the retina is completely detached, it will show a sudden loss of vision.
Diabetic retinopathy: This is a common ophthalmic complication in diabetic patients, and it is also one of the main causes of blindness in ophthalmology. The longer the course of diabetes, the more serious the retinopathy.
Stroke: most stroke patients do not have any premonition in advance, only a few stroke patients can appear a few minutes of half body, half face numbness, hemiplegia, sudden visual ghosting and other premonitions one hour or a few months before the onset.
It can be seen that the sudden inability to see things clearly is not just as simple as Lao Hua. Therefore, once the vision suddenly decreased, it should be timely medical treatment, do related ophthalmic examination, according to the different causes of treatment. At ordinary times, in order to avoid eye diseases, in addition to paying attention to and treating the original hypertension, arteriosclerosis, diabetes and other primary diseases, we also suggest that the elderly friends should keep optimistic mood, avoid overwork and take more physical exercise.
