Introduction
Normal-tension glaucoma refers to glaucoma with normal intraocular pressure, which can be managed using medications, laser therapy, or surgery. Medications include timolol maleate ophthalmic solution and levobunolol hydrochloride ophthalmic solution. Calcium channel blockers such as nimodipine sustained-release tablets and nifedipine controlled-release tablets may also be used. Argon laser trabeculoplasty or selective laser trabeculoplasty are treatment options. If visual field and optic disc damage continue to progress, surgical intervention is recommended.
Glaucoma with normal intraocular pressure, generally referring to normal-tension glaucoma, can be managed through various treatments such as medication, laser therapy, and surgical intervention to alleviate symptoms.
1. Medication: Under a doctor's guidance, patients may use beta-blockers such as timolol maleate eye drops or levobunolol hydrochloride eye drops. These medications help reduce aqueous humor production, thereby lowering intraocular pressure, and also decrease ocular blood flow. Additionally, calcium channel blockers prescribed by a physician—such as nimodipine sustained-release tablets or nifedipine controlled-release tablets—may be used to improve local blood supply to the optic nerve and enhance microcirculation.
2. Laser therapy: For normal-tension glaucoma, laser treatment options may be considered under medical supervision. Common procedures include argon laser trabeculoplasty and selective laser trabeculoplasty.
3. Surgical treatment: In cases where the above treatments are ineffective or when visual field and optic disc damage continue to progress, surgical intervention may be recommended by a physician, such as trabeculectomy.
