If the patient’s eye axis exceeds 28mm, he/she may not necessarily lose his/her eyesight after the age of 45.
The length of the eye axis of an adult is normally around 24mm, and a general increase of 1mm in the eye axis increases myopia by about 300 degrees. If the length of the patient’s eye axis exceeds 28mm, it means that the patient is suffering from a high degree of myopia. Highly myopic patients have a significant decrease in naked eye vision, and may also have myopic fundus lesions such as retinal detachment, degeneration, etc., but the patient does not necessarily lose their eyesight.
If a patient with high myopia develops serious fundopathy such as macular atrophy, the patient’s vision can be severely impaired and the patient may go blind. If the patient does not have serious fundopathy, he/she will not lose his/her eyesight.
It is recommended that patients with high myopia consult a doctor to evaluate their condition and follow the doctor’s instructions for treatment and care. Patients should also take care of themselves and avoid over-exercise.
