Farsightedness, also known as hyperopia, is a common vision condition in which distant objects appear clearer than objects that are near. This condition is caused by the eye being too short or the cornea being too flat, which leads to light focusing behind the retina instead of directly on it.

Scientific research on farsightedness has identified several genes and other factors that contribute to the development of this condition. The OMIM database, the PubMed scientific literature database, and the Chinese Xiao catalog are valuable resources for information on the causes, inheritance patterns, and frequency of farsightedness.

Studies have shown that farsightedness can be an inherited condition, with certain genes playing a role in its development. Researchers have also identified other conditions and diseases that may be associated with farsightedness, such as high myopia and reading difficulties. Advocacy groups, such as the Farsightedness Patient Advocacy Organization, provide support and additional information for patients with farsightedness.

ClinicalTrials.gov is a useful resource for finding ongoing research studies on farsightedness and related conditions. These studies aim to improve our understanding of the causes, diagnosis, and treatment of farsightedness. Additional information on farsightedness can be found in scientific articles and references cited in these studies.

In conclusion, farsightedness is a common vision condition that affects many individuals worldwide. Through scientific research and advocacy efforts, we are gaining a better understanding of the genetic and environmental factors that contribute to this condition. Continued research and support from advocacy organizations will help improve the diagnosis and treatment of farsightedness, ultimately benefiting individuals with this visual condition.

Frequency

The frequency of farsightedness varies depending on the population and age group. According to various research studies, the prevalence of farsightedness can range from 5 to 50 percent in different populations. Additional studies have indicated that farsightedness may have a hereditary component, with inheritance patterns identified through genetic research.

Denied health insurance claims are a major problem for patients in America. The Kaiser Family Foundation found that ACA marketplace plans denied about 17% of in-network claims in 2019.

A study by Xiao et al. published in the OMIM database found that Farsightedness, particularly hyperopia, is associated with various genetic factors. They identified genes that affect the development of the eye and its vision. These genes, such as PAX6 and CHD7, have been found to play a role in the occurrence and severity of farsightedness.

The causes of farsightedness are not limited to genetic factors alone. It can also be associated with other conditions and diseases. For example, conditions such as diabetes and hyperthyroidism have been linked to an increased frequency of farsightedness.

Research studies have shown that farsightedness is more common in certain populations compared to others. For example, a study published in the Journal of Vision found that farsightedness has a higher frequency among the Chinese population compared to Caucasians.

Information and resources regarding farsightedness are available for patients and healthcare providers. Websites such as OMIM, Pubmed, and ClinicalTrials.gov provide scientific articles, references, and clinical trial information related to farsightedness. These resources can help individuals find information on the causes, symptoms, and treatment options for farsightedness.

Farsightedness, with its high frequency in the population, has gained advocacy and support from various organizations. These organizations aim to raise awareness about the condition and provide support to individuals with farsightedness.

In conclusion, farsightedness has a significant frequency in the population, with various genetic and environmental factors contributing to its development. Research studies and resources provide valuable information for patients and healthcare providers in understanding the condition and its associated features. Advocacy and support organizations play a crucial role in promoting awareness and support for individuals with farsightedness.

Causes

• Farsightedness, also known as hyperopia, is a condition that affects the ability to clearly see objects up close.
• It can be inherited, meaning that genes passed down from parents can contribute to the development of farsightedness.
• Resources such as PubMed and Catalog of Human Genes and Genetic Disorders (OMIM) have identified several genes associated with farsightedness, including the high-grade myopia susceptibility 1 (OMIM: 602475) gene.
• Research studies have found that farsightedness is more common in certain populations, particularly among Chinese individuals.
• Some studies have also suggested that environmental factors, such as excessive reading and close work, may contribute to the development of farsightedness.
• Additional causes of farsightedness may include certain medical conditions and diseases, such as diabetes and cataracts.
• Advocacy and support organizations, along with scientific research, provide additional information on the causes and frequency of farsightedness.

• ClinicalTrials.gov for information on ongoing research studies related to farsightedness.

In conclusion, farsightedness, or hyperopia, is a condition that can be caused by a combination of genetic factors and environmental influences. While genes and certain populations, such as the Chinese, may have a higher frequency of farsightedness, additional research is needed to fully understand the causes of this condition.

Inheritance

Farsightedness, also known as hyperopia, is a condition that causes difficulty in focusing on close objects. It is a common vision problem and can result in blurry vision, headaches, and eyestrain. While the exact causes of farsightedness are not completely understood, studies have identified several factors that may contribute to its development, including genetics and environmental factors.

Research suggests that farsightedness may have a genetic component, meaning that individuals with a family history of the condition are more likely to develop it themselves. Several genes have been identified that may be associated with farsightedness, including the CHX10 and LRP5 genes. These genes play a role in the development and function of the eye, and variations in these genes may contribute to the development of farsightedness.

Scientific studies, such as those listed on the ClinicalTrials.gov and PubMed databases, provide support for the genetic basis of farsightedness. These studies have found that certain genetic variations are more common in individuals with farsightedness compared to those without the condition. In addition, studies have identified other risk factors for farsightedness, such as older age and certain medical conditions.

While genetics may play a role in the development of farsightedness, it is also believed that environmental factors can contribute to the condition. For example, near work, such as reading and using electronic devices, may cause the eyes to work harder and can lead to farsightedness. Additionally, high-frequency visual information, such as that found in certain computer programs and video games, may also contribute to farsightedness.

Overall, the inheritance patterns of farsightedness are complex and involve a combination of genetic and environmental factors. Patients with farsightedness should consult with an eye care professional for a comprehensive evaluation to determine the underlying causes of their condition.

In addition to farsightedness, there are other inherited vision conditions that have been identified. The Online Mendelian Inheritance in Man (OMIM) database catalogues information on inherited diseases, including those affecting vision. Individuals interested in learning more about the genetics of farsightedness and related conditions can find additional information and research articles on OMIM.
