Glaucoma cannot currently be cured permanently, and vision already lost because of glaucoma cannot be restored. However, treatment can often slow or stop further damage to the optic nerve and help protect remaining vision. The National Eye Institute explains that glaucoma can be treated with prescription medicines, laser procedures, or surgery, depending on the type and severity of the disease.
There is currently no permanent cure for glaucoma. Damage to the optic nerve caused by glaucoma is generally irreversible, and existing vision loss cannot be restored.
The main goal of treatment is to control the condition and protect remaining eyesight.
Treatment aims to:
The earlier glaucoma is detected and treated, the better the opportunity to protect remaining vision.
The most common treatment is prescription eye drops that lower pressure inside the eye. Some medicines reduce the amount of fluid produced, while others help fluid drain more effectively.
Depending on the situation, treatment may include:
Treatment is individualized according to glaucoma type, eye pressure, optic nerve damage, overall health, and response to therapy.
Laser treatment can be used for some forms of glaucoma. For open-angle glaucoma, a procedure called trabeculoplasty can improve the drainage of fluid from the eye and lower eye pressure.
Important points include:
The National Eye Institute notes that the effect of laser treatment can decrease over time for some patients.
If medicines and laser treatment do not adequately control glaucoma, an ophthalmologist may recommend surgery. Procedures can create or improve pathways for fluid to leave the eye and reduce pressure.
Surgical options can include:
Surgery can help protect vision by reducing further damage, but it cannot restore vision already lost from glaucoma.
Because glaucoma often progresses without obvious symptoms, following the recommended treatment plan is important even when vision seems unchanged.
Helpful steps include:
The National Eye Institute emphasizes that glaucoma medicines need to be taken as prescribed because treatment is intended to prevent further vision loss rather than immediately improve how the eyes feel or look.
There is currently no permanent cure for glaucoma, and vision lost from optic nerve damage cannot be restored. However, medicines, laser treatment, and surgery can lower eye pressure and help slow or prevent additional damage.
Early detection and consistent treatment are important because glaucoma can have few symptoms in its early stages. Anyone diagnosed with glaucoma should follow an individualized care plan and maintain regular appointments with an eye-care professional.
