There are many types of glaucoma, such as primary angle-closure glaucoma, open-angle glaucoma, and normal-tension glaucoma. Once glaucoma is definitively diagnosed, medication can be used first to control intraocular pressure. If medications cannot control the pressure, surgery may be considered. However, generally, if it is early stage, and there is no damage to vision or visual field, with not very high intraocular pressure, medication can be considered first. If the intraocular pressure remains very high, medication fails to stabilize it, and there is a decline in vision or damage to the visual field, then surgery is needed.

What are the symptoms of glaucoma?

Glaucoma refers to a group of eye diseases characterized by increased eye pressure, leading to optic nerve atrophy and vision loss. The symptoms of glaucoma are mainly caused by increased eye pressure, resulting in eye pain. In cases of acute angle-closure glaucoma, symptoms include eye pain along with nausea, vomiting, photophobia, and tearing, which can easily be mistaken for neurological diseases. Chronic glaucoma symptoms, such as headache, nausea, and vomiting, are less pronounced, and eye discomfort is also more concealed during attacks, making early detection difficult. Therefore, it is important for glaucoma patients to undergo early examination and diagnosis, and to receive appropriate treatment in order to protect the optic nerve and prevent severe vision loss.

What are the symptoms of glaucoma?

Glaucoma is a group of eye diseases characterized by characteristic optic nerve atrophy and visual field defects, with pathological elevated intraocular pressure as its main risk factor. The main symptoms of glaucoma include blurry vision and blocked vision. Due to different types, it is also accompanied by other eye symptoms such as eye pain, eye bulging, foggy vision, as well as pain in the nasal root and head, and even nausea and vomiting.

What is glaucoma?

Glaucoma is one of the main blinding eye diseases in ophthalmology, with a certain genetic predisposition, affecting 10 to 15 percent of direct relatives of patients. Intraocular pressure is the pressure exerted by the contents within the eyeball against its inner wall. Glaucoma is a group of diseases characterized by distinctive optic nerve atrophy and visual field defects, and pathologically increased intraocular pressure is one of the main risk factors for glaucoma. The level of increased intraocular pressure and the tolerance of the optic nerve to pressure damage are primarily related to the occurrence and progression of glaucomatous optic nerve atrophy and visual field defects.

Early symptoms of glaucoma

There are many types of glaucoma, and the symptoms vary between different types. Some patients with glaucoma might not have noticeable symptoms in the early stages; others may only experience mild eye soreness and occasional blurred vision, which can improve with rest; some present with insidious vision decline and field defects. Glaucoma refers to a group of progressive optic nerve damage that eventually impairs vision, mainly associated with pathological elevation of intraocular pressure. Glaucoma is the second leading cause of blindness worldwide, and it is the top irreversible blinding eye disease. Common symptoms of glaucoma include blurry vision, vision decline, field defects, and acute attacks, often accompanied by eye pain, headache, nausea, vomiting, and more. If glaucoma symptoms occur, or there is a suspicion of glaucoma, it is advised to visit an ophthalmology clinic for comprehensive examinations like visual acuity, intraocular pressure, fundus examinations, etc., to determine the cause and provide targeted treatment, actively reduce intraocular pressure, and protect the optic nerve.

Glaucoma open angle vs closed angle differences

Primary glaucoma is clinically divided into two major categories: angle-closure glaucoma and open-angle glaucoma. The difference between them is that angle-closure glaucoma is due to a pre-existing abnormal configuration of the iris, leading to a mechanical blockage of the anterior chamber angle by peripheral iris tissue, which obstructs the outflow of aqueous humor, thus causing an increase in intraocular pressure. In contrast, open-angle glaucoma has a normal appearance of the anterior chamber angle, which remains open, and its increase in intraocular pressure is due to a pathology in the trabecular meshwork’s aqueous humor outflow system, increasing the resistance to aqueous outflow. Currently, the ratio of primary angle-closure glaucoma to primary open-angle glaucoma is about 3:1, making it the most common type of glaucoma in China.
