Factors associated with refractive defects in an urban population of the peruvian andes. To determine the factors associated with refractive defects in an urban population of the Peruvian Andes. A cross-sectional analytical study of secondary data analysis was performed, using all the records of the patients who attended the ophthalmological consultation between January and Maythe variables of type of ametropia astigmatism, myopia and hyperopiaSex, age, occupation and place of residence of the patients.

Of the attended, the average age was 30 years cayses deviation It was found that cases had a lower frequency of myopia p: 0. It was found that some of the socio-labor factors evaluated were associated with refractive defects in a population of the central Andes of Peru, these results can be taken cakses account for future research, preventive plans does bumble work for guys ophthalmologic pathologies and as a basis for Future research in similar populations.

Determinar los factores asociados a los defectos refractivos en una población urbana de los andes peruanos. Descriptores: Defectos refractivos; Trastornos de la visión; Astigmatismo; Miopía; Hiperopía; Instituciones de atención ambulatoria; Peru. A metropia is a very frequent condition diagnosed in the human population. Youngsters are often the most affected population; 4 sex and professional occupation are other influencing factors.

Ametropia has also thme reported among children. Thus, the aim of the current study was to determine the factors associated with refractive errors in an urban population rsfractive in the Peruvian Andes. Analytical cross-sectional study carried out based on the database of aare units in Huancayo City, Peruvian central what do the color rings mean on bumble. A census-type convenience sampling was adopted; it included patients with ametropia who were treated in the optical center from Rrrors to May and whose data were available in the database of the institution.

A trial lens box and an optotype were refractige in do genital warts cause cervical cancer refractive measurements, which have followed international standards recommended by expert medical technologists. Data were collected in whag database of the investigated institution, after it authorized such a procedure.

Information was double digitized and, subsequently, subjected wha data quality control. Ethical aspects were always respected in order to assure data confidentiality; an identification code was assigned to each record and all data capable of identifying the assessed patients were deleted. Absolute and relative frequencies of categorical what are refractive errors of vision and what causes them were subjected to descriptive statistics.

It was done by using generalized linear models, based on Poisson distribution and log link function, by taking into consideration robust models. Figure 1 shows the percentage of patients with refractive errors, based on the assessed eye. Figure 1 Percentage errprs patients with refractive errors living in a city in the Peruvian central highlands. Astigmatism was not associated with factors such errord sex, age, professional occupation or place of residence Table 2.

Housewives recorded low myopia frequency p: 0. The other evaluated factors were not associated with myopia. Table 3. The current research was the first to determine arw frequency of, and factors associated with, refractive errors diagnosed in patients living in a city in the Peruvian central Andes. It can be used to vusion identifying the manifestation of these visual issues in this population, as well as to provide reference for new information collection in future studies.

The analyzed variables were not associated with astigmatism, and it means that astigmatism equally affects participants of both sexes, belonging to all categorized age groups, regardless of their place of residence or professional occupation. This outcome can be explained by the fact that astigmatism is a congenital refractive error and that a large percentage of the population is born with this condition.

Furthermore, studies have shown that patients can develop it at any age rrfractive that it is often associated with what are refractive errors of vision and what causes them refractive errors such as myopia and hyperopia. These data corroborate a study about the prevalence of astigmatism in a population living in the United States, whose most common diagnoses — recorded from the highest to the lowest frequency -were astigmatism, myopia, wwhat and presbyopia. Patients older than 60 years and housewives recorded the lowest myopia frequency rates; this outcome confirmed that this pathology most often happens at early ages.

Hyperopia was mostly associated with individuals older than 60 years, causrs because it often happens after that age. This technique should be performed in oof -mainly in strabismus cases -because it provides more reliable refraction, as well as in patients with high hyperopia levels because they may not be detected without cycloplegia. Moreover, the literature lacks studies with populations who live in the mountains; thus, it was not possible making comparisons to populations living in these environments.

Despite these limitations, the current results are relevant, since they were the andd ones recorded in this field for the herein described population, a fact that generates hypotheses and sets the precedent for future investigations about this topic. Based on data of a population living in Peruvian central highlands, it was possible concluding that housewives and individuals older than 60 years were less likely to have myopia and presented higher hyperopia frequency rates; students recorded the lowest hyperopia rates.
