Transconjunctival Needling Revision Versus Medical Treatment

June 26, 2013 updated by: Ricardo Suzuki, University of Sao Paulo General Hospital

Early Transconjunctival Needling Revision With 5-fluorouracil Versus Medical Treatment in Encapsulated Blebs: a 12-month Prospective Study

When the glaucoma filtering surgery failures (intraocular pressure rises again), the options is start to use the hypotensive eye drops again (medical treatment). However, in some cases (encapsulated blebs), there is a simple surgical revision that can revival the primary failure surgery. It calls transconjunctival needling revision. In this study, the investigators compare the efficacy of this revision versus medical treatment in 12-month follow up in eyes with encapsulated blebs.

Detailed Description

To compare the efficacy of transconjunctival needling revision (TNR) with 5-fluorouracil versus medical treatment (MT) in glaucomatous eyes with uncontrolled intraocular pressure (IOP) due to encapsulated bleb after trabeculectomy Prospective, randomized, interventional study. A total of forty eyes of 39 patients with elevated IOP and encapsulated bleb diagnosed at maximum 5 months after primary trabeculectomy with mitomycin C were included. The eyes were randomized to either TNR with 5-fluorouracil or MT (hypotensive eyedrops). A maximum of two TNR per patient was allowed in the needling arm. All eyes were followed up for 12 months. Success of treatment was defined as IOP ≤ 18mmHg and 20% reduction from baseline at last follow up.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Transconjunctival needling revision
Eyes with primary glaucoma surgery failure with encapsulated bleb submitted to surgical revision
Procedure: Transconjunctival needling revision
Surgical revision. A 25 Gauge needle was inserted under the subconjunctival space and perforate the encapsulated bled. The encapsulated bleb was ruptured with sweeping movement up and down, back and forth.
Active Comparator: Medical treatment
Eyes with primary glaucoma surgery failure with encapsulated blebs were treated with medical treatment (hypotensive eye drops)
Drug: Medical treatment
Hypotensive eye drops are initialized one by one regarding intraocular pressure control. Nonspecific beta blocker and/or prostaglandin, followed by carbonic anhydrase inhibitors and/or selective alpha agonist.
