Aim of the Work:This study aims to investigate the safety, efficacy and feasibility of trabeculectomy using a porous Collagen Matrix that contains a connected porous structure (Ologen ® ) in the control of IOP in glaucoma patients without the need for medical therapy.
Methods:The study includes 25 eyes from 24 patients that met the inclusion criteria. All eyes underwent trabeculectomy with the Ologen ® implant that provides a space with a dynamic and physiological aqueous reservoir system. The operation was considered successful if IOP is <15mmHg without need of IOPlowering drops at 18 months of follow up.
Results:The target IOP was achieved in 21 out of the 25 eyes (84%), the remaining four eyes all had an IOP of 16 mmHg at 18 months. Short-term complications consisted of seven cases of bleb leakage treated with bandage contact lens and one case of mild choroidal effusion which resolved after observation alone.
Conclusions:We can conclude that this technique can provide safety, effectiveness and short learning curve for ophthalmology trainees with lower incidence of peri-operative and post-operative complications.Further studies may be required to prove stability and long-term efficacy in management of glaucoma patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
