Ophthalmic diseases have become a common disease. Therefore, ophthalmic treatment has attracted more and more attention. In the process of ophthalmic treatment, we often use tools such as suturing forceps, intraocular scissors, corneal scissors, etc. Today we will mainly introduce the treatment of glaucoma and the possible used tools.
Glaucoma is one of the main causes of blindness in China, and the damage to visual function caused by glaucoma is irreversible and the consequences are extremely serious. Generally speaking, glaucoma cannot be prevented, but if it is detected early and treated appropriately, most patients can maintain useful visual function throughout their lives. Therefore, the prevention of blindness in glaucoma must emphasize early detection, early diagnosis and early treatment. The main purpose of treatment is to reduce eye pressure, reduce eye tissue damage, and protect visual function.
The glaucoma damage is permanent and it cannot be reversed. But medication and surgery can help prevent further damage. To treat glaucoma, your eye doctor may use one or more treatments.
Glaucoma is usually controlled with eye drops. Daily use of these eye drops can reduce eye pressure. Some people do this by reducing the water-based liquid produced by the eyes. Others reduce the pressure by helping the fluid flow better through the drainage angle.
Glaucoma medications can help you maintain your vision, but they may also have side effects. Some eye drops may cause:
1) Tingling or itching sensation
2) Red eyes or red skin around the eyes
3) Pulse and heartbeat changes
4) Changes in energy levels
5) Breathing changes (especially if you have asthma or difficulty breathing)
6) Dry mouth
7) Blurred vision
8) Eyelash growth
9) Changes in the color of the eyes, the skin around the eyes or the appearance of the eyelids.
All medicines may have side effects. Some medicines may cause problems when taken with other medicines. It is important to give your doctor a list of each medicine that you take regularly. If you think you maybe suffer from the side effects of glaucoma medicine, be sure to talk to your ophthalmologist.
Do not change or stop taking glaucoma medicine without talking to an ophthalmologist. If you are about to run out of medicine, ask if the ophthalmologist should re-prescribe it.
There are two main types of laser surgery for glaucoma. They help the water drain from the eyes. These procedures are usually performed in an ophthalmologist's office or an outpatient surgery center.
1) Trabeculoplasty. This surgery is suitable for people with open-angle glaucoma. Ophthalmologists use lasers to make the drainage angle work better. In this way, the fluid can flow out correctly and reduce eye pressure.
2) Irisotomy. This is for people with angle-closure glaucoma. The ophthalmologist uses a laser to make a small hole in the iris. The hole helps fluid flow to the drainage corner.
Some glaucoma surgeries are performed in the operating room. It creates new drainage channels for aqueous humor to leave the eyes. Here the doctor may often use tools such as adjustable speculum, medical clamps forceps, corneal cannula to complete the surgery.
1) Trabeculectomy. This is where your ophthalmologist forms a small flap on the sclera. He or she will also form bubbles (such as pockets) in the conjunctiva, called follicles. It is usually hidden under the upper eyelid and cannot be seen. The aqueous humor will be able to drain from the eye through the flap and enter the vesicles. In the air bubbles, the liquid is absorbed by the tissues around the eyes, thereby reducing intraocular pressure.
2) Glaucoma drainage device. Your ophthalmologist may insert a small drainage tube into your eye. Glaucoma drainage implants send fluid to the collection area. Your ophthalmologist creates this reservoir under the conjunctiva. Then, the fluid is absorbed into nearby blood vessels.
