Myopia of more than 1,300 diopters means that the patient has developed a high degree of myopia, and the patient is at higher risk of developing retinopathy and passing myopia on to future generations. The severity of myopia is categorized according to the degree of myopia, generally less than 300 degrees of myopia is called low myopia, between 300 degrees and 600 degrees of myopia is called moderate myopia, more than 600 degrees of myopia is called high myopia, and more than 1,000 degrees of myopia is called ultrahigh myopia. Patients with hyperopic myopia are prone to myopia-related complications such as retinal degeneration zones and dry retinal tears, and are prone to passing myopia on to their offspring. It is recommended that patients with high myopia seek prompt medical attention to evaluate their condition and follow the doctor’s instructions for treatment and care.
