Deep Sclerectomy with Porous Collagen in Open-angle Glaucoma, Short-term Study.

Aim: To assess the role of porous collagen in deep sclerectomy (DS), with and without trabeculo-Descemet membrane (TDM) rupture.

Patients and methods: Forty-six eyes with different types of open-angle glaucoma and medically uncontrolled intraocular pressure (IOP) were selected. DS was performed in all cases. Ologen was implanted as a single large piece in the scleral lake and subconjunctival space in all cases with and without TDM rupture.

Results: A total sample of 46 open-angle glaucoma patients were included in the study. The mean ± standard deviation (SD) IOP was 25.6 mm Hg ± 10.6 (range 12-58 mm Hg) pre-operatively. On follow-up, the mean ± SD IOP was 6.1 mm Hg ± 3.7 (range 2-20 mm Hg) 1 day postoperatively and 9.3 mm Hg ± 4.0 (range 4-23 mm Hg) after 1 month of follow-up, at 12 months the IOP was at 12.1 mm Hg ± 3 (range 8-18 mm Hg). The overall mean ± SD IOP reduction percentage was 48.3% ± 21.3 (range 0.0-86.2). Comparing mean IOP reductions at last follow-up between TDM rupture cases and non-TDM cases (Mann-Whitney test), the mean ± SD IOP reduction in TDM rupture patients was 12.1 ± 8.0 mm Hg (range 2-27) meanwhile, in non-TDM rupture patients it was 14.3 ± 11.4 mm Hg (range 0-50). However, the difference in IOP reduction between the two groups was not significant. (p = 0.689).

Conclusion: Porous collagen can enhance the results of DS; also, it helps to proceed with DS in cases of TDM rupture without converting to trabeculectomy.
