Glaucoma is the second leading cause of blindness in Taiwan Province Province. It often steals our beautiful eyesight without people noticing anything unusual. Where is this scary glaucoma? Simply put, it is actually a pathological change of the optic nerve. When the intraocular pressure exceeds the tolerance range of the optic nerve or the blood supply of the optic nerve is unstable, the optic nerve may be damaged, and then the visual field will be lost, which is called glaucoma.
Glaucoma can be roughly divided into acute glaucoma and chronic glaucoma. The former can make patients feel headache, nausea, vomiting and sudden blurred vision. Most of the latter have no obvious symptoms, and they don't realize that things are not good until their eyesight gradually deteriorates, but at this time, the optic nerve has been seriously damaged, causing irreversible damage. In order to avoid the visual damage or even blindness caused by glaucoma, early detection and early treatment are very important! We must remind everyone once again that high intraocular pressure is only a risk factor for glaucoma, not a necessary condition for glaucoma diagnosis. As mentioned above, glaucoma may still occur with normal intraocular pressure, and examination of fundus optic nerve and regular follow-up are the safest preventive methods!
