Glaucoma is a condition where increased intraocular pressure damages the optic nerve, risking vision loss over time. In Karachi, patients have access to both non-surgical and surgical treatment options. Choosing between them depends on how advanced the disease is, how well other treatments have worked, and your overall health and preferences. Here’s a guide to the main types of glaucoma treatments available, especially in a setting like The Eye Center – Dr. Mahnaz Naveed Shah & Associates.
Non-Surgical Treatment Options
Non-surgical glaucoma treatments are typically the first line of action. They’re less invasive and often reversible, with fewer immediate risks. Key methods include:
- Medications: Prescription eye drops or oral medications to lower fluid production or increase drainage. Regular use, correct technique, and follow-ups are essential.
- Laser treatments: Including Selective Laser Trabeculoplasty (SLT), Argon Laser Trabeculoplasty (ALT), and newer modalities. These non-invasive or minimally invasive laser procedures help improve drainage through the eye’s natural channels.
Advantages:
- Lower risk compared to surgery
- Usually outpatient / clinic-based
- Quicker recovery
- Can reduce or delay need for surgery
Limitations:
- May be less effective in advanced glaucoma
- Effectiveness may diminish over time; repeat treatment or additional interventions may be needed
- Side effects from medications or temporary laser effects may occur
Surgical Treatment Options
When non-surgical treatments are insufficient, or if glaucoma is advanced, surgery becomes an option. In Karachi, skilled ophthalmic surgeons can offer:
- Traditional surgeries:
- Trabeculectomy – creating a new drainage route by making a flap in the sclera and allowing fluid to exit under the conjunctiva, forming a filtering bleb.
- Tube-shunt / drainage device implantation – inserting a small tube or valve to divert excess fluid.
- Minimally Invasive Glaucoma Surgery (MIGS):
Less aggressive surgical options involving smaller incisions, faster recovery, and reduced risk of complications. MIGS may involve micro-stents, micro-shunts, or devices that help fluid drainage with less tissue disturbance.
Advantages:
- Greater reduction in intraocular pressure (IOP) — helpful in advanced disease
- Reduced dependence on medications
- MIGS options offer a balance: more pressure lowering than non-surgical, but less risk than full surgery
Risks / Considerations:
- Possible complications: infection, bleeding, low pressure (hypotony), scarring, or cataract formation
- Longer recovery periods for more invasive surgeries
- Careful follow-ups required; sometimes revisions are needed
Which Should You Choose?
- Non-surgical treatment is often tried first—medication and/or laser—especially in early or moderate glaucoma.
- If IOP remains uncontrolled, optic nerve damage progresses, or medications cause intolerable side effects, surgical options may be recommended.
- MIGS may be considered earlier in suitable patients because of favorable risk profiles.
