Surgical Technique and Post-operative Management

Technique: Conjunctival peritomy, episcleral plate suturing 8–10mm posterior to the limbus (usually superotemporal), tube trimmed to appropriate length and inserted into anterior chamber, covered by donor pericardium or scleral patch graft, conjunctiva closed.

The hypertensive phase (6–12 weeks post-operatively): Fibrous encapsulation raises IOP transiently; additional medications or needling may be needed during this period. Long-term IOP achieved: approximately 14–18 mmHg.

Frequently Asked Questions

Is this condition treatable?

Yes. Glaucoma cannot be cured, but modern treatment — eye drops, laser, or surgery — can slow or halt progression when started early. The key is early detection through regular eye examinations.

How often should I be examined?

Most patients with glaucoma need a detailed eye exam every 3–6 months. The exact interval is decided by your treating consultant based on severity, target pressure, and disease stability.

Will I lose my vision?

Vision loss from glaucoma is preventable in most patients who adhere to treatment and follow-up. Progressive vision loss usually occurs only when disease is advanced or treatment is irregular.
