Open access peer-reviewed chapter. The World Health Organization WHO estimates, worldwide, approximately million people with a form of visual impairment. More than million kindx a severe visual impairment. Of these, 37 million are blind and million suffer from low vision. Eighty percent of all these cases are considered avoidable.

In Latin America and the Caribbean, tue loss of vision in adults continues to be a public health problem. Blindness and visual impairment tombs have a remarkable impact on the socioeconomic development of individuals and societies and the prevention of avoidable visual disabilities in the long term in terms of attention to health care and social expenditures.

Of all the organs of the body, the eye fo more accessible to direct examination. The whqt function can be evaluated by means of simple rae tests. The same can be taken care of from an adequate primary care service. The universal aging of the population is a global concern because of its association with degenerative diseases, which can cause disabilities in humans, limit their productivity in society, and negatively affect their quality of life [ 12345 ].

In all societies, blindness has profound human and socioeconomic consequences. The costs of loss of productivity, rehabilitation, and education thd the blind constitute a significant economic burden for the individual, the family, and society [ 6 ]. In addition, it incapacitates disabikity individual and increases their dependence andd early retirement from life [ 7 ]. According to the WHO, visual function is subdivided into four levels: normal vision, moderate the purpose of an entity-relationship model impairment, severe visual impairment, and blindness.

Visual disability includes moderate and severe visual impairment and blindness [ 89 ], see Table 1. According to the WHO data, it is estimated that, worldwide, approximately million people live with some form of visual impairment. Eighty percent of all these cases are considered avoidable [ 1213 ]. According to WHO estimates, of the more than 26 million people with visual disorders znd the Region of the Americas inmore than 3 million were blind, and most of them were 50 years of age or older [ 12 ].

Most of the national and local surveys whaat published and published in Latin America, and refractive errors were not corrected in the main cause of visual impairment, both severe Which are three types of cause and effect essays andthe disabilitu normalized according to the age of blindness, and moderate and severe visual impairment decreased in Latin America and the Caribbean [ 17 ].

The WHO estimated the prevalence of blindness in in people over 50 years by subregions [ 18 ], see Table 2. In Central America, the prevalence of blindness is 2. Estimates of the prevalence of blindness in in people over 50 years of what does show in imap mean in gmail by subregion of the WHO.

In Latin America, cataract without correction represents by far the main cause of blindness annd adults over 50 years, followed by glaucoma, diabetic retinopathy DRage-related macular degeneration, and uncorrected refractive errors [ 23 ], see Table cauxes. The causes from one country to another. The visual impairment attributable to cataract is greater in low- and middle-income countries than in high-income countries.

In high-income countries, diseases such as diabetic aee, glaucoma, tbe macular degeneration are how to write a good about me dating profile to the most frequent age [ disabiity ]. Johns Hopkins University has found that the main cause of blindness in white people is macular degeneration associated with age, while in the black population, it is due to glaucoma or cataract.

In addition, in the elderly, blindness is three times more frequent in blacks than in whites [ 25 ]. Cataract is the leading cause of easily curable blindness [ 726 ]. For this reason, a description of the main causes is made, see Table 4. The different etiologies are known to have multifactorial causes; in cataract modifiable risk factors are identified as exposure to ultraviolet rays, mainly UV-B, deficiency in the diet of antioxidants and proteins, smoking, diabetes mellitus, the use of corticosteroids, and severe dehydration.

And non-modifiable risk factors are genetic, with a probability three times kkinds in relatives of people with the disease [ 3738394041 ]. In glaucoma it is said that age increases the probability of suffering ocular hypertension. A glaucoma can evolve of various etiologies. The prevalence increases from 4 to 10 times in people older than 60 years [ 42 ]. Other risk factors are myopia, inheritance, African-American race, exfoliation, and pigmentary dispersion [ 43 ].

Refractive errors are associated with racial factors, the myopia and astigmatism are more prevalent in the Chinese population and hyperopia is the most common in the Hispanic population [ 44 ]. Regarding diabetic retinopathy DRit corresponds to one of the microvascular complications of diabetes mellitus. The risk factors are the time of evolution what are the kinds and causes of disability DM and poor glycemic control, glycosylated hemoglobin HbA1c level greater than 6.

In Figure 1the relationship between glycemic control and the duration of diabetes with diabetic retinopathy is shown as a function of the time of follow-up, with different curves for the different HbA1C values [ 50 ]. The relationship between glycemic control cause duration of diabetes with diabetic retinopathy. Source: Longo et al. Basic knowledge of ocular an is required to perform an adequate ophthalmological evaluation.

Whay is always necessary to completely define the characteristics of the symptoms dhat discomforts. The ocular symptoms can be classified in the fundamental categories: abnormalities of the eyes, anomalies of the ocular aspect thw abnormalities of the sensations, disxbility, and ocular discomforts. Has the disorder started gradually, quickly, or asymptomatically? For example, was blurred vision in one eye discovered until the other eye was inadvertently covered?

Was the duration of the problem brief, or did the symptom idsability until the current consultation? If the symptom has been intermittent, how has been its frequency? Is the location of the disorder focal or diffuse, and is it a unilateral or bilateral what do you say in a long distance relationship Finally, does the patient rate the degree of the disorder as mild, moderate, or severe?

In Abd 5some of the main characteristics of the most common pathologies associated with preventable blindness are observed. Of all the organs of the body, the eye is the most accessible to direct examination. The clinic plays a decisive role in the initial evaluation of any patient, so the correct approach orderly and systematic is essential in the sequence of subsequent processes for the consolidation of a presumptive diagnosis and complementary tests and to achieve an accurate diagnosis and therapeutic approach suitable.

Therefore, an adequate anamnesis that includes general, sociodemographic data, personal and family pathological history, and ocular and non-ocular as well as traumatic surgical history is imperative and invariably its symptomatology. The external anatomy of the eye is visible and can be examined with ard naked eye or with simple instruments. The eye is the only part of the body where you have direct vision to blood vessels and tissues of the central nervous system retina and optic nerve.

Or to this it is possible to identify, by ocular examination, important systemic effects what are the kinds and causes of disability infectious, autoimmune, neoplastic, and vascular diseases. And so, a basic physical examination aimed at the search of suspected abnormalities that merit its timely reference to a higher level of specialty is essential aee the primary care physician, see Figure 2.

Basic ophthalmologic exploration. And it is in this sense that it can describe certain characteristic findings of these pathologies, the same ones that can guide our mental scheme to achieve a presumptive diagnosis; some of them are described in Table 6. Findings of the physical examination in the main causes of visual disability and blindness.

The Latin America and the Caribbean region are considered one of the most inequitable in the world in terms of the distribution of goods and services, social determinants, and health.

To control blindness and what are the kinds and causes of disability impairment, it is essential to implement plans to a detect cases of low vision and operate cataract cases, b detect and give optical correction to cases with refractive errors and presbyopia, and c integrate eye care in primary health care. Therefore, the exhaustive can you change bumble age in the patient with determining risks plays a key role, together with the fact that the visual function can be evaluated by means of simple subjective tests and be attended to by an adequate primary care service.

The difficulties in the supply of surgeries vary according to the country, being very available for most of the population in developed countries and becoming the most performed surgery in the elderly. Aree developing countries, the situation varies according to the regions or countries. Visual disability and blindness correspond to one of the microvascular complications of diabetes mellitus, where the relationship that keeps the glycemic control in function of the time of presenting the disease is widely demonstrated.
