What is glaucoma?

The problem of glaucoma cannot be ignored, because in many cases glaucoma is a primary glaucoma, which is a congenital disease. It usually leads to symptoms such as sharp decrease in vision, conjunctival congestion, nausea and vomiting, so it must be diagnosed and treated in time.

1 Most glaucoma is primary glaucoma. Primary glaucoma: According to the morphology of the anterior chamber angle and the severity of onset, it is divided into acute and chronic angle-closure glaucoma, open-angle glaucoma, etc.: 1. Acute angle-closure glaucoma: This type is more common in middle-aged and elderly people, accounting for 90% of those over 40 years old. The incidence rate is higher in women, with a male to female ratio of 1:4. The disease comes on violently with mild to severe symptoms. When the disease occurs, the anterior chamber is narrowed or completely closed, and there is a sudden onset of severe eye swelling and headache, sharp decrease in vision, eyeballs as hard as stones, conjunctival congestion, nausea and vomiting, constipation, and increased blood pressure. At this time, the systemic symptoms are more severe and can be easily misdiagnosed as gastroenteritis, encephalitis, neuralgia and other diseases.

2. If timely diagnosis and treatment is not received within 24-48 hours, the patient may become completely blind and unable to sense light. This is called "fulminant glaucoma". However, clinically, some patients have a low tolerance for pain and only experience discomfort in the eye sockets and eyes. There may even be no symptoms in the eyes, but the pain may spread to the forehead, ears, maxillary sinus, teeth, etc. Acute angle-closure glaucoma is actually caused by the recurrence of chronic angle-closure glaucoma. Glaucoma treatment: Medication: There are currently a variety of drugs used to treat glaucoma. They lower intraocular pressure or control intraocular pressure fluctuations by reducing aqueous humor production or promoting aqueous humor drainage.

3. Laser iridotomy and laser iridoplasty can be used to treat angle-closure glaucoma. Argon laser trabeculoplasty can effectively treat open-angle glaucoma, and selective trabeculoplasty provides a new treatment for open-angle glaucoma. Surgery: If intraocular pressure is not well controlled after using one or more drugs or laser treatment, anti-glaucoma surgery such as iridectomy, trabeculectomy, and drainage valve implantation should be performed according to the situation.
