Firstly, the excessive aqueous production would cause high eye pressure. The aqueous is a clear fluid that is produced in the eye by the ciliary body. The ciliary body produces too much aqueous, the pressure in the eyes higher. Or inadequate aqueous drainage could cause high eye pressure as well. The eye trauma is another possibility to cause high eye pressure, because an injury of the eye can influence the balance of aqueous production and drainage from the eye. Additionally, some certain medications have side effect of causing high eye pressure in certain persons.
As we know that glaucoma can cause the eye pressure. But on the other hand, there are also many other reasons which can cause high eye pressure too. If you have not avoided eating some foods or drink, it may cause high eye pressure. For example, you drink too much caffeine. Then, improper ratio of the production and drainage of aqueous humor is the main cause of eye pressure. Some physical activities like lifting heavy objects or standing upside down can increase eye pressure temporarily. It is believed that psychological stress plays an important role in increasing the ocular pressure. In other words, you can read many other material and so that they can help you to solve your problem.
Many factors will cause high eye pressure. Such as glaucoma, diabetes, cardiovascular disease, rainbow eyelashes inflammation, cataracts, myopia and other eye diseases may occur elevated intraocular pressure, trauma can also cause high intraocular pressure and optic nerve but because everyone IOP tolerance is different, though some IOP is higher than normal but not have occurrence of the damage to the optic nerve and visual field, known as ocular hypertension.
