While vision lost to glaucoma cannot currently be restored, treatment can slow — and often prevent — further damage.
All glaucoma treatments focus on one goal:
Lowering intraocular pressure (IOP) to protect the optic nerve. The right treatment depends on the type of glaucoma, the severity of damage, and how your eye responds over time.
Prescription Eye Drops
For many patients, treatment begins with medicated eye drops.
These drops work by either:
- Reducing the amount of fluid the eye produces
- Improving how fluid drains from the eye
When used consistently, eye drops can effectively control pressure for years.
Important Considerations
- Drops must be used exactly as prescribed
- Missing doses can allow pressure to rise
- Some medications may cause mild side effects such as redness or irritation
Your doctor may adjust medications over time to achieve the best pressure control.
Laser Treatment
Laser procedures are commonly used when drops are insufficient or difficult to tolerate.
Selective Laser Trabeculoplasty (SLT)
SLT improves drainage through the eye’s natural outflow system.
It is:
- Performed in-office
- Typically painless
- Quick (usually under 10 minutes)
- Often repeatable
Laser treatment may reduce or eliminate the need for drops in some patients.
Minimally Invasive Glaucoma Surgery (MIGS)
For certain patients, especially those undergoing cataract surgery, minimally invasive procedures may be recommended.
MIGS procedures:
- Improve fluid drainage
- Use very small incisions
- Have faster recovery times than traditional surgery
They are often used in mild to moderate glaucoma cases.
Traditional Glaucoma Surgery
In more advanced cases, surgical procedures may be necessary to create a new drainage pathway.
Examples include:
- Trabeculectomy
- Tube shunt implantation
These procedures are typically reserved for patients whose glaucoma is not controlled with drops or laser therapy.
Treatment Is Ongoing
Glaucoma management is not a one-time fix. It requires:
- Regular monitoring
- Ongoing testing
- Adjustment of treatment as needed
Because glaucoma can progress slowly, maintaining follow-up appointments is essential.
Can Glaucoma Be Cured?
At this time, there is no cure for glaucoma.
However, with early detection and proper treatment, most patients can preserve useful vision for a lifetime.
What Happens After Treatment Begins?
Your doctor will monitor:
- Eye pressure levels
- Optic nerve appearance
- Visual field results
- OCT imaging
Treatment may be adjusted if pressure goals are not achieved.
When to Discuss Treatment Changes
Contact your eye doctor if you experience:
- Increased eye redness
- Vision changes
- Eye pain
- Difficulty tolerating medications
Prompt adjustments can prevent unnecessary damage.
