The Use of Ologen Implant in Childhood Glaucoma Surgeries: A Review

PurposeThis study assesses the effectiveness and safety of using Ologen implants (Aeon Astron Europe BV, Leiden, The Netherlands) as an adjunctive therapy in childhood glaucoma surgeries.MethodsWe systematically reviewed the existing literature across various electronic databases to examine the effectiveness and safety of Ologen implants in childhood glaucoma surgeries.ResultsOur analysis encompassed 14 studies on the use of Ologen implants in childhood glaucoma. Among these, seven were prospective, five were retrospective, and two did not specify their study design. Success rates varied depending on the type of surgery and the included childhood glaucoma subtype. The success rates for Ologen implants-augmented surgeries were as follows: 33.3-70% for trabeculectomy, 50-81% for combined trabeculotomy-trabeculectomy procedure, 33%-87% for glaucoma drainage device, and 60% in deep sclerectomy.ConclusionOlogen implant has a potential role in mitigating postoperative fibrosis and enhancing success rates in various childhood glaucoma surgeries. However, the existing literature is limited. Future comparative prospective studies with larger cohorts are needed.
