Intraoperative Optical Coherence Tomography-Guided Bleb-sparing Epithelial Exchange: A Modified Approach

With the advent of newer technologies, real-time anterior segment optical coherence tomography (oct) integrated with the operating microscope has become possible. we are proposing the technique of bleb revision with greater precision under direct visualization of bleb anatomy and extent of tissue depth allowing better localization and easy maneuvering with lesser complications. in this surgical technique, bleb revision was performed using intraoperative real-time oct incorporated in opmi lumera 700 microscope. live surgical and oct view were seen on a common screen together. a moderately elevated, diffuse functional bleb was noted after three months of bleb revision in both cases with controlled intraocular pressure. intraoperative oct-guided bleb-sparing epithelial exchange is an adjunctive technique for bleb repair surgery with an increased precision of surgery which can reduce complications, minimize surgical time and maximize surgical outcome.
