What is the difference between cataract and glaucoma?

The main difference between cataract and glaucoma is reflected in the lesion site, clinical manifestations, treatment and prognosis.

1. The lesion site

glaucoma is mainly caused by optic nerve damage caused by high intraocular pressure, while cataract is a disease that occurs in the lens of the eye, usually caused by aging, trauma and other factors.

2. Clinical manifestations of

glaucoma patients include eye pain, headache, nausea, reduced vision, etc., and may also be accompanied by dark green cornea. The main manifestations of cataract patients are painless, progressive vision loss, blurred vision or color vision changes.

3. Treatment and prognosis

Glaucoma is generally an irreversible disease. Even through surgery or laser treatment, the patient's vision may not be restored, but only the original vision can be maintained. In contrast, cataract is a reversible disease. After drug or surgery treatment, lens function may return to normal, vision will also be restored.
