Pinpointing a leaky bleb with a blue surgical skin marker

Area of Science:

• Ophthalmology
• Surgical Techniques

Background:

• Glaucoma management often involves procedures like trabeculectomy and bleb needling.
• Post-surgical complications can include bleb leaks, leading to hypotony and vision impairment.

Purpose of the Study:

• To introduce a simple, cost-effective method for identifying the precise location of bleb leaks after needling.
• To improve the success rate of surgical repair for persistent bleb leaks.

Main Methods:

• A surgical skin marker was used to stain the conjunctiva at the suspected site of a bleb leak.
• The marker highlighted the leakage points, enabling accurate visualization and suture placement.
• The technique was applied in a patient with advanced glaucoma experiencing a persistent bleb leak post-needling.

Main Results:

• The surgical skin marker successfully identified two closely situated openings of the bleb leak.
• Accurate suture placement guided by the marker led to complete closure of the leaks.
• Postoperative outcomes included restoration of intraocular pressure and an elevated bleb.

Conclusions:

• Conjunctival staining with a surgical skin marker is a simple, inexpensive, and effective method for localizing bleb leaks.
• This technique aids in precise surgical repair, resolving persistent hypotony and improving bleb function.
