When your glasses are “old”, you should look at these.

Abstract: glaucoma is an eye disease in which the intraocular pressure increases abnormally, which exceeds the maximum limit that the optic nerve of the eye can bear, resulting in optic nerve damage and visual field defect, and finally makes vision decline or even blindness. It is also one of the most common blinding eye diseases in the elderly. After a certain age,

people will experience a stage of old eye dizziness, but in fact, old eye dizziness may not be as simple as temporary visual fatigue, but it may also be a signal from some eye diseases.

so what eye problems do the elderly need to pay attention to? Ophthalmologists point out that these four eye diseases are most likely.

first: presbyopia

presbyopia is a common eye degenerative disease. With the growth of age, after the age of 40, the lens gradually hardens, and the function of ciliary muscle gradually declines, making the adjustment function of the eye difficult, and there will be blurred vision when looking at nearby things, that is, what we call presbyopia.

and

are like some old people reading newspapers and books. They unconsciously tilt their heads back or extend their arms to let the books and newspapers go farther to see clearly, or they need to look at places with better light to see clearly. Moreover, they can’t last long when they look close. Their eyes will swell and sour over time. At this time, you can wear appropriate presbyopic glasses after optometry to improve your vision.

second: cataract

the proportion of cataract in the elderly over 50 years old has gradually increased. According to the survey, the prevalence of cataract in people aged 50 is 6.83%, while the prevalence of cataract in people aged over 70 is 59.95%. This kind of eye disease is a blinding eye disease. When they first suffer from cataract, the lens of most elderly people is only turbid in the peripheral part, but the central part remains transparent. At this time, it does not affect their vision. However, with the progress of the disease, the lens fiber edema and the continuous increase of inter fiber liquid make their vision worse and worse, which can lead to blindness in severe cases.

at present, the first choice for the treatment of cataract is surgery. It is OK to replace a lens.

third: Glaucoma

glaucoma refers to an eye disease in which the intraocular pressure increases abnormally, exceeding the maximum limit that the optic nerve of the eye can bear, resulting in optic nerve damage and visual field defect, and finally making vision decline or even blindness. It is also one of the most common blinding eye diseases in the elderly.

the first symptom of many glaucoma patients is eye pain, often accompanied by swelling and pain of orbital and nasal roots. Severe patients can also have severe migraine, even nausea and vomiting. In terms of visual objects, it can be manifested as slow decline of vision, rainbow when looking at the light at night, etc. in the late stage, when looking directly in front, I feel that the field of vision reached by the remaining light is significantly reduced. Once

and

are diagnosed as glaucoma, their high intraocular pressure can be controlled in a safe range through drugs or surgery, so that glaucoma can be controlled temporarily, but glaucoma can not be completely cured, and it needs lifelong follow-up care. The fourth place of

and

: diabetic retinopathy

diabetic patients with

are poor in blood sugar control. They can be combined with varying degrees of retinopathy, such as microangioma, retinal hemorrhage, hard exudation, cotton soft exudation, vitreous body blood, fibrous vascular proliferation, macular edema, and even retinal detachment. In addition to actively controlling blood sugar,

and

need regular fundus examination for diabetics. Once the old people themselves have diabetes, it is necessary to be vigilant to see blurred vision, and see if they have combined retinopathy in order to minimize injury.
