Trabeculectomy with Ologen versus Mitomycin C in Juvenile Open-Angle Glaucoma: A 1-Year Study

Ophthalmic Res. 2017;57(4):230-238. doi: 10.1159/000456719. Epub 2017 Mar 15.

Abstract

Background: We assessed bleb morphology and the intraocular pressure (IOP)-lowering effect of trabeculectomy with ologen compared to mitomycin C (MMC) in juvenile open-angle glaucoma (JOAG).

Methods: This is a prospective interventional comparative study conducted on 40 eyes (20 patients) with medically uncontrolled JOAG, randomly operating one eye for trabeculectomy with ologen (group A: 20 eyes) and the other with MMC (group B: 20 eyes). IOP measurement, SITA standard perimetry, and spectral domain optical coherence tomography (OCT) for retinal nerve fiber layer (RNFL) thickness were all done pre- and postoperatively. Postoperative blebs were assessed clinically using the Moorfields bleb grading system (MBGS) and anterior segment OCT (AS-OCT). All patients were examined for up to 1 year postoperatively.

Results: The mean postoperative IOP was statistically significantly lower than the mean preoperative IOP at each follow-up in each group. At 1 year, the mean postoperative IOP was significantly lower in group A. According to the MBGS, blebs with an ologen implant showed significantly better scoring than those with MMC. AS-OCT showed that ologen-induced blebs had significantly more fluid-filled spaces, cleavage planes, and less fibrosis.

Conclusion: Ologen resulted in a lower long-term postoperative IOP, a better bleb morphology, and fewer complications. Our results suggest that ologen may be a useful alternative to MMC in JOAG.
