Viscoelastics Enable Dissection of Anterior Closed Funnels in Proliferative Vitreoretinopathy: A Retrospective Case Series.

ABSTRACT

Introduction: The present study aimed to describe a case series of patients in which a cohesive ophthalmic viscous device (OVD) was used to viscodissect and posteriorly displace the retina in cases of total retinal detachment complicated by proliferative vitreoretinopathy, operated with minimally invasive pars plana vitrectomy. Case Presentations Three patients with a mean age of 67 years were included in the present study. One eye was aphakic, while the others were pseudophakic. OVD injection was performed through the limbus in the aphakic eye and via pars plana in the pseudophakic eyes. In all cases, the OVD injection led to a posterior displacement of the detached retina with a smooth dissection. No complications related to the surgery were observed. At the last follow-up visit, the retina was attached in all cases, with an improvement in visual acuity. Conclusion: To conclude, the injection of a cohesive OVD anterior to the detached retina allowed to posteriorize and viscodissect to some extent the retina, facilitating the implant of trocars.
