Is high myopia hereditary?

In general, high myopia usually refers to a refractive error greater than 600 degrees. Patients with high myopia are advised to undergo regular fundus examinations to allow timely detection and treatment as directed by a physician. This type of myopia is defined in ophthalmology as pathological myopia, which presents clear clinical symptoms such as significant vision decline and visual fatigue, and corrected vision is difficult to restore to normal levels.

一般情况下，高度近视是指600度以上。对高度近视Patient而言，日常需要养成良好的用眼习惯，避免长时间用眼，控制好用眼时间，避免近视度数加深。日常也要佩戴好眼镜，必要时可以配合Doctor进行近视Surgery，帮助视力恢复。

High myopia can be hereditary, generally associated with autosomal recessive inheritance, pathogenic genes affecting axial length of the eye, genetic polymorphisms increasing susceptibility, and parental myopia elevating risk. Most cases of high myopia follow this inheritance pattern; when both parents carry the pathogenic gene but are unaffected, their children have a higher probability of inheriting two copies of the pathogenic gene, leading to high myopia, with a disease incidence higher than that of the general population.

In general, high myopia cannot be cured by moving the eyes, although moderate eye movement may help reduce visual fatigue to some extent. The core issue of high myopia is excessive elongation of the axial length or abnormal corneal curvature, which are structural changes that cannot be reversed by any muscle exercises. Patients with high myopia should undergo cycloplegic refraction and fundus examinations every six months and avoid intense physical activities such as diving and boxing.

Whether individuals with high myopia can donate blood depends on their individual eye health condition. If there are no complications, they can usually donate blood under a doctor's guidance. However, if complications exist, blood donation is not recommended. Individuals with high myopia should avoid prolonged near-eye work, and regularly look into the distance or close their eyes to relax, in order to reduce eye fatigue and discomfort.

High myopia may be caused by factors such as genetic predisposition,不良 eye habits, abnormal eye development, lens disorders, and retinal diseases. It can usually be treated by wearing appropriate glasses or contact lenses, undergoing vision therapy, or surgical treatment. If you experience sudden vision loss or other eye discomfort, it is recommended to seek medical attention promptly.

Under normal circumstances, regularly consuming blueberries can help prevent severe myopia and has a certain positive effect in this regard. Blueberries are rich in anthocyanins, which are potent antioxidants. Anthocyanins promote the regeneration of rhodopsin in retinal cells, aiding in the protection of vision. At the same time, they also help the eyes adjust to light and improve night vision.

Myopia usually refers to nearsightedness. In general, high myopia may be caused by不良 eye habits, poor dietary habits, genetic factors, excessive eye axis length, abnormal intraocular pressure, and other reasons. It is recommended to seek timely medical attention, identify the underlying cause, and then under the guidance of a qualified physician, undergo recovery treatments such as conventional therapy, medication, or surgical treatment. The appropriate treatment method should be selected based on individual circumstances.
