Aim: This pilot study evaluates the safety and efficacy of a novel surgical technique using fibrin glue to treat bleb dysesthesia post-trabeculectomy due to intrapalpebral extension. Background: Trabeculectomy remains the gold standard for control of intraocular pressure (IOP) in refractory glaucoma. Bleb dysesthesia following antifibrotic-enhanced trabeculectomy is common, resulting in a significant decrease in quality of life. Symptoms include pain, foreign body sensation, and excessive tearing. Treatments include lubrication, topical nonsteroidal anti-inflammatory drugs (NSAIDs), bandage contact lens, bleb needling, compression sutures, Nd:YAG laser treatments, autologous blood injection, and cryopexy. These procedures can be time-consuming, risk bleb function, and may be ineffective at symptom control; thus, a novel technique is required. Technique: This is a retrospective case series of eyes undergoing bleb dissection with scleral cutdown and conjunctival closure with ARTISS fibrin tissue glue. Reported cases have been followed up for 6 months. Outcomes assessed include complications, IOP, medication usage, subjective pain score, visual field, and cup-to-disk (C:D) ratio. Conclusion: This small pilot series demonstrated that patients suffering from bleb dysesthesia due to intrapalpebral bleb extension can be successfully treated with a novel surgical approach combining conjunctival dissection to sclera with fibrin tissue glue closure. There was no significant effect on bleb function and no contribution to glaucoma progression over a 6-month period. A significant reduction in patient discomfort with no new surgical complications was noted. Clinical significance: This demonstrates a safe and effective novel surgical approach to treat patients with this condition. The technique is easily learnt and can be employed in an outpatient setting. The technique is readily accepted by patients in group who are often reticent to undergo further intervention. Most importantly, it does not compromise bleb function or destabilize glaucoma control.
