Subscleral Trabeculectomy with Ologen implant versus Mitomycin C in primary infantile glaucoma: up to 103 months’ follow-up (original) (raw)
2023, Research Square (Research Square)
To compare the effect of SST augmented with Mitomycin C (MMC) versus Ologen implant as secondary procedures for treatment of primary congenital glaucoma. Methods This is a retrospective study evaluating records of 38 eyes that had undergone SST with MMC (group M, 17 eyes) versus Ologen (Group O, 21 eyes), by authors of the study. The study primary endpoint was set at 5 to 9 months postoperatively and the secondary endpoint was the last follow-up. A successful outcome was an IOP </=18 mmHg for infants < 1 year, and </= 20 mmHg for older ones. Results Follow-up duration was 1.25 to 51 (26.79 +/-27.583) months in group M, and 0.25 to 103 (22.86+/-28.991) months in group O (p = .673). The mean preoperative IOP was 28.06+/-3.929 in group M and 26.95+/-6.095 in group O (p = .522). Reduction of IOP was signi cant in group M at all follow-up visits, but starting at the fourth postoperative month in group O. Recorded IOP in groups M and O, respectively, was 14.9+/-6.437 and 12.1+/-5.043 at the primary endpoint, and 22.35+/-8.536 and 22.52+/-10.152 (p > .05) at the secondary endpoint. A successful outcome was achieved in groups M and O, respectively, in 47.1% and 47.6% at the primary endpoint and in 47.1% and 52.4% at the secondary endpoint (p > .05). Cataract, posterior synechiae and pupillary abnormalities were insigni cantly different in both groups (p = .623). Conclusions Ologen implant was comparable to MMC, in terms of e cacy and safety. Reoperations are inadvisable prior to 4 months of Ologen implants.
