Introduction

In general, 800 degrees of myopia is considered a severe level of nearsightedness, which is highly susceptible to complications that may potentially lead to blindness. However, if severe complications do not develop, it does not necessarily mean one will become blind in old age. Patients with high myopia should undergo regular eye examinations, especially fundus examinations, to detect and treat any possible complications at an early stage.

Generally speaking, 800 degrees of myopia is considered a severe level of myopia, which carries a high risk of complications that may potentially lead to blindness. However, if no serious complications develop, it is not certain that a person will go blind in old age. Detailed analysis is as follows:

An 800-degree myopia is classified as high myopia, which poses a significantly higher risk of eye complications compared to individuals with normal vision. It may lead to serious complications such as retinal detachment and macular holes. If these complications are not treated promptly, they may cause a severe decline in vision or even blindness.

However, if an individual with 800-degree myopia does not develop any serious ocular complications, or if the complications are treated timely and effectively, and the individual maintains regular eye examinations, adopts good eye-use habits, and follows a healthy lifestyle, they may not necessarily become blind in old age.

Patients with high myopia should undergo regular ophthalmic examinations, especially fundus examinations, to detect and treat any potential complications at an early stage. If individuals with high myopia experience sudden vision loss, visual distortion, or the appearance of floating shadows in front of their eyes, they should seek immediate medical attention for thorough evaluation and diagnosis. In daily life, it is important to maintain proper eye hygiene, avoid excessive eye strain and strenuous physical activities, and maintain healthy lifestyle habits to reduce the risk of blindness.

What causes myopia?

In general, myopia may be caused by genetic factors, poor eye-use habits, pseudomyopia, axial myopia, or fundus lesions associated with high myopia. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate interventions under a doctor's guidance. In daily life, maintain regular作息 (sleep-wake cycles), avoid staying up late, and spend at least two hours outdoors each day to help slow the progression of myopia.

It is recommended to seek timely medical attention, identify the underlying cause, and then improve the condition under a doctor's guidance through conservative management, medication, surgical treatment, or other methods. In daily life, avoid rubbing the eyes and prevent ocular trauma.

Is it possible to have surgery for myopia over 1000 degrees?

Under normal circumstances, whether a person with myopia over 1000 degrees can undergo surgery needs to be determined based on the patient's specific ocular conditions and overall health status. If experiencing any discomfort, it is recommended to seek timely medical advice from a professional ophthalmologist. Prior to surgery, a comprehensive eye examination should be conducted at a正规 hospital, including corneal topography, fundus photography, intraocular pressure measurement, and other relevant tests. Postoperatively, it is important to follow medical instructions for care, use medications as prescribed, and attend follow-up appointments regularly.

What should be done about strabismus in children?

Children with high hyperopia, myopia, or astigmatism may experience excessive eye accommodation in order to see clearly, which can easily lead to eye misalignment and strabismus, as well as symptoms such as blurred vision. The primary solution involves wearing properly corrective glasses after cycloplegic refraction. Under a doctor's guidance, atropine sulfate ophthalmic gel can also be used to achieve cycloplegia, along with lutein chewable tablets to provide nutritional support for the eyes.
