What are the symptoms of primary open angle glaucoma?

summary

What expression does the symptom of glaucoma have? Glaucoma is one of the three major blinding diseases that lead to human blindness. It has a great impact on patients. Glaucoma is mainly caused by the increase of intraocular pressure, such as optic disc depression and visual field defect, which can eventually lead to severe blindness. Understand the symptoms of glaucoma, so that we can find early treatment, then, what are the symptoms of glaucoma?

What are the symptoms of primary open angle glaucoma?

The first symptom of glaucoma is high intraocular pressure. Once suffering from glaucoma, it will lead to elevated intraocular pressure, and then the disease will worsen, endangering the health of patients. Therefore, intraocular pressure should be controlled properly. Under normal circumstances, the normal intraocular pressure range is 10-21 mmHg. Touching the eyeball with fingers is elastic. When the intraocular pressure rises to 25-40 mmHg, touching the eyeball with fingers will feel harder. When it rises to 40-70 mm Hg, touch it with your fingers again, and the eyeball is as hard as stone.

Nausea and vomiting, some people suffering from glaucoma, nausea and vomiting symptoms will appear. When the occurrence of nausea and vomiting and other symptoms, should be alert to the occurrence of glaucoma. Elevated intraocular pressure can also reflexively cause the excitation of vagus nerve and vomiting nerve center, resulting in severe nausea and vomiting.

Vision decline, when people use eyes continuously, ciliary muscle is very tired, vision will indeed decline. But after a full rest, vision can return to normal. Medical experiments have found that when people continuously see for more than 2 hours, their vision will decrease by 2-3 lines (e.g. from 1.0 to 0.7). Therefore, we should not use our eyes excessively. We should take a rest every hour. This is a good way to ensure that our eyes continue to work.

matters needing attention

Glaucoma patients also need to maintain a light diet, do not eat spicy food, quit smoking and drinking, meal time is not high, too long interval, because hunger may lead to gastrointestinal blood concentration to the head, making intraocular pressure rise. Patients should actively cooperate with the doctor for treatment, to avoid all kinds of easy to lead to elevated intraocular pressure and glaucoma attack.
