Can high astigmatism lead to blindness?
High astigmatism refers to a condition where the astigmatism degree of a patient exceeds 600 degrees.
I. Causes:
- Physiological factors: Excessive eye use or prolonged viewing of electronic devices can lead to eye fatigue, which in turn may result in high astigmatism.
- Pathological factors: Diseases of the cornea, such as keratoconus, can also cause high astigmatism.
II. Treatment:
For patients with physiological high astigmatism, it is important to maintain proper eye usage in daily life, avoid overexertion of the eyes, and correct the condition by wearing frame glasses, which can help improve symptoms. For pathological high astigmatism, targeted treatment measures should be taken based on the underlying cause. If it is caused by corneal diseases, glucocorticoid drugs such as dexamethasone eye drops or tobramycin dexamethasone eye drops can be used under medical supervision. In severe cases, surgical treatments like excimer laser surgery may be recommended.
Patients are advised to protect their eyes in daily life, avoid staying up late or prolonged viewing of electronic devices such as televisions and smartphones, which may exacerbate the condition. A balanced diet rich in vitamins, such as carrots and tomatoes, is also recommended to help supplement nutrition and promote recovery. If any significant discomfort occurs during this period, medical attention should be sought promptly to avoid delay in treatment.
