Baja visión funcional en adultos de América Latina: resultados de las encuestas poblacionales realizadas en 15 países. Send correspondence to: Hans Limburg, hlimburg quicknet. The weighted average arf for the 10 national surveys was 1. These data can be helpful in planning and developing low vision services for the region; large countries such as Brazil and Mexico would need more studies.

Many of these individuals might benefit from low vision services that allow people to live more independently 1. While the epidemiology gow treatable and preventable eye diseases is well documented, epidemiological data on FLV are very scarce. These estimates suggest that the number of people with FLV has doubled since The sharp increase in FLV might be explained by the increased life expectancy worldwide and the increased risk for chronic eye diseases with irreversible loss of sight at higher ages.

The study reported a prevalence of FLV for all ages of 1. Prevalence increased considerably by age, from 0. A population-based study from Pakistan in reported a prevalence of FLV in people aged 30 years and older how many types of visual impairment are there 1. Another study from Nigeria conducted in reported a prevalence of FLV in people aged 40 years and older of 3.

These estimates have been how many types of visual impairment are there to assess the need and guide impairmetn for low vision ther in the region. With advances in treatment options, the proportion of people with avoidable blindness and visual impairment is decreasing in a number of countries Given these trends, the number of people with FLV is expected to increase in the coming decades.

The results of this analysis could be used to facilitate adequate planning to meet the increasing need for low vision services in the region. Data from 15 population-based surveys on blindness and visual impairment conducted in LAC from to 11 using the rapid assessment of avoidable blindness RAAB method and four using the rapid assessment of cataract surgical services RACSS method were analyzed.

Both RAAB and RACSS use a multistage random cluster sampling methodology in which, in the first stage, small population units usually census enumeration areas CEAs are selected from a sampling frame through systematic sampling. This ensures a random selection with a probability proportional to the size of the population unit 13, For the second stage of sampling RACSS was applied until to select eligible individuals within the CEA through the "random walk" method, a standard survey method at the time for assessing immunization coverage.

With new insights, from onward, this method was modified to the compact segment sampling used in the RAAB method Because the definition of FLV, data collection, and data analysis were identical in both survey methods, the findings of the 15 ars are fully comparable. The results of yhere 15 studies were published in peer-reviewed journals but findings on FLV were not included because until the coding w as not available.

For this review, the original data from all 15 surveys were reanalyzed and the relevant data extracted after consent from the principal investigators. The population data were obtained at the time of the survey from the national bureau of statistics of the country where the survey was conducted and are part of the data files from that survey.

In people identified as having FLV, the main causes, plus age- and sex-specific awful meaning, and VA, were extracted.

Therefore, the studies selected for this review included 10 national, population-based surveys. Individual needs for low vision care are more difficult what is the purpose of definition writing assess because they depend vksual education, level of visual disability, etc.

Data from the original databases were reanalyzed and how many types of visual impairment are there patients were examined. Each individual study adhered to the provisions of the Declaration of Helsinki. The principal investigators and the agencies that funded each of the 15 studies granted the authors written permission to analyze their data for this study. Inthe total population 50 years and older for what is a dog food topper 15 countries where the surveys were conducted was million or Ten of how many types of visual impairment are there surveys covered the entire country while the remaining five surveys covered cities or states.

Table 1 shows the total and sex-specific prevalence of FLV for each country sample. The sample prevalence varied from 0. Prevalence differed significantly between men and women. Table 2 shows the sex- and age-specific prevalence of FLV by year age groups for each country sample. As shown in the table, prevalence increased with age. Figure 1 illustrates the increase with age as well as the considerable variation in prevalence across countries.

Table 4 shows the principal causes of FLV for the individuals expressed as proportions of the total affected. However, there was considerable aree across countries. The bottom half of Table 4 shows the percentage of main causes of FLV that are preventable. The majority The impaiement of visual impairment may have implications for the type of services required i. One study from Santiago, Chile, reports a prevalence of 0. Data from India, Nigeria, and Pakistan suggest that the prevalence of FLV in younger age groups in those countries is low Figure 2.

One important finding in this study was the fact that This finding provides a strong argument for blindness prevention as a major strategy to reduce FLV. Another interesting finding was that prevalence can you like someone after 3 weeks FLV varied by impairmenr in some countries.

These differences in prevalence by sex should be investigated further. Strengths and limitations. One strength of this analysis was the fact that all 15 included studies used the same survey methodology, protocols, definitions, age groups, and methods of data analysis. Ten of the studies were national surveys, with a sample representative of the entire country, and seven of them were conducted in the last four years.

This study also had some limitations. First, in five of the countries, the survey area was limited to a state, province, district, or city, and therefore the data might not be representative of the entire country. This how many types of visual impairment are there especially important for countries with large populations like Brazil and Mexico. The authors hope that by including these data, other researchers may conduct similar surveys in other parts of these countries to get more representative data on blindness, visual impairment and FLV.

Second, some of the surveys were conducted about a decade ago, so the findings may not be the same as today. This could have affected the accuracy of the survey measurements of FLV from glau-coma-a major cause of FLV in LAC-as central how many types of visual impairment are there remains intact until a very late stage of the disease whereas based on visual field assessment patients might have qualified as having FLV.

Because glaucoma is a major cause aer FLV in LAC, it is likely that the data from the surveys presented here underestimated the prevalence of FLV and, consequently, the number of people who may benefit from low vision services. The authors hope that these findings on FLV will be helpful in planning for the provision and development of fhere low vision services at the country level in the LAC region.
