3 simple steps you recognize in time the visual defects in the elderly
Biological factors related to aging are the leading cause of occurrence of pathologies of the elderly people, who are having to cope with muscle weakness, balance disorders, neurological diseases and, not least, visual defects.
The most well-known, common and widespread visual impairment that appears after 45 years of age is, surely, presbyopia, which, as we know, the progressive inability to see the object observed closely.
The testimony of the fact that this is a classic visual disease of old age comes from its own linguistic derivation: "presbyopia" in greek means "by old" view.
But, besides this common visual defect, the elders also accuse other disorders that, very often, are overlooked, and that, however, portend the possible occurrence of other diseases to the eye.
But, one wonders, how to properly interpret its signs?
Let\'s find out together.
1. Dimming vision / decreased visual acuity: cataract can
The progressive decrease of visual acuity is a serious wake-up call that should prompt the opportunity to verify the possible presence of cataracts, the visual defect of the most popular elderly after presbyopia.
The phenomenon is characterized by opacification, slow evolution, of the lens.
In truth, there are different signals that portend the possible onset of this disease, among these: the blurred vision, poor night vision, and, finally, a successor need for greater lighting for reading.
Unfortunately, at present, the only remedy is represented by the surgical removal of the lens itself, intervention of this routine that, in general, is performed under local anesthesia with no particular risks and now well-equipped rooms.
2. Narrowing the field eyepiece: possible glaucoma
The diagnosis of glaucoma is very important: it is manifested by a progressive alteration of the visual field, which gradually tends to shrink gradually until its complete disappearance.
This alteration is due to the progressive increase of the fluid pressure inside the eye.
This defect of the elderly affects about 10% of people with impairments of sight and, unfortunately, can lead to blindness, of which this disease it is one cause in the West.
The progression of the disease in question is slow and subtle: sometimes we even realize it until the total loss of vision.
3. Sudden decreased vision: can ocular ischemia
Some individuals, particularly those with, for example, carotid artery disease, transient ischemic attack together may experience symptoms of hypotensive retinopathy, a severe form of chronic ischemia that strikes the eye and endo-orbital structures sprayed ophthalmic artery. The first useful trick for noticing in time of the possible presence of this defect of vision in the elderly is to not underestimate the possible visual acuity that occurs almost in 50% of cases, so sudden.
Only in some cases, for other blocks, in fact, you may feel a eye pain and / or orbit.
A visual defect in the elderly, if not detected in time and not corrected promptly, can seriously and heavily reflected not only on the vision in itself but, more generally, on the quality of life of the elderly.
A careful examination, is of the view that the anatomical structure of the eye, it is imperative for the early detection of visual impairment in the elderly.
