What are the symptoms of pre glaucoma?

summary

Glaucoma is a kind of diseases that cause optic nerve and visual field damage because of pathological elevated intraocular pressure. In addition, the normal IOP value is between 10-21 mmHg. If the IOP is greater than 24 mmHg, it is pathological IOP increase. What are the symptoms of pre glaucoma? Let's talk about it

What are the symptoms of pre 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.

Some people develop nausea and vomiting after suffering from glaucoma. 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.

There are many symptoms of glaucoma, headache and eye distension is one of them. Because of the sharp rise of intraocular pressure, trigeminal nerve terminal slightly stimulated, reflexively cause trigeminal nerve distribution area pain, patients often feel migraine and eye pain.

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.
