Advanced guarded filtration surgery augmented with Mitomycin-C anti-scarring agent for adult glaucoma.
Trabeculectomy remains the benchmark gold-standard filtration surgery worldwide for patients with moderate-to-severe glaucoma whose intraocular pressure cannot be controlled with medications or laser therapy. The procedure creates an alternative drainage pathway (a controlled fistula) that permits excess aqueous humor to bypass the diseased trabecular meshwork.
At Atharva Glaucoma Centre, Dr. Amola Gandhi performs modern guarded trabeculectomy augmented with intraoperative anti-fibrotic agents—specifically Mitomycin-C (MMC) or 5-Fluorouracil (5-FU). These pharmacological adjuncts modulate the body's natural wound-healing response, preventing scar formation over the surgical flap and ensuring long-term low target pressures.
Under gentle local or peribulbar anesthesia, a small, partial-thickness rectangular scleral flap is fashioned in the upper eye wall beneath the upper eyelid. A calibrated application of dilute Mitomycin-C is applied to the subconjunctival tissue using surgical sponges and thoroughly irrigated with sterile saline.
A micro-punch excision creates the drainage fistula into the anterior chamber, accompanied by a small peripheral iridectomy to prevent blockages. The scleral flap is re-approximated using releasable or adjustable micro-sutures, allowing fluid to filter into the subconjunctival space where it forms a discreet, elevated cushion called a filtration bleb.
The long-term success of trabeculectomy relies heavily on attentive post-operative management. Dr. Amola Gandhi personally monitors bleb morphology, anterior chamber depth, and pressure response in the crucial first 6 weeks.
Using slit-lamp laser suture lysis or releasable suture withdrawal, the filtration rate is carefully titrated to achieve target pressures often as low as 10 to 12 mmHg without causing hypotony.
Proven advantages of augmented trabeculectomy for advanced adult glaucoma:
The surgical procedure typically takes between 40 and 60 minutes under local anesthesia. Patients are discharged on the same day after a short post-operative observation.
Vision is typically blurry for the first 1 to 2 weeks as the eye adapts to lower pressure. Most patients resume quiet desk work within 1 to 2 weeks, while heavy lifting and swimming should be avoided for 4 to 6 weeks.
No surgery can bring back vision lost to optic nerve atrophy. Trabeculectomy is performed to safeguard and preserve your remaining vision by stopping further disease progression.
