NCT04490876

Brief Summary

The aim of this study is to report outcomes of pars plana vitrectomy (PPV) in retinal detachment (RD) accompanied with proliferative vitreoretinopathy (PVR) after extensive Brilliant Blue G-Assisted internal limiting membrane (ILM) peeling using a 3D visualization system. This is retrospective consecutive case series of 14 eyes treated with PPV for RD repair. The patients were follow for 7 to 47 months (mean follow-up: 14.1 months ).

Outcome Measures

Primary Outcomes (1)

  • Mean Best Corrected Visual Acuity

    mean follow-up: 14.1 months

  • Spectral Domain OPTICAL COHERENCE TOMOGRAPHY (SD-OCT) IMAGING of the MACULA

    mean follow-up: 14.1 months

Retinal Detachment with PVR

Proliferative vitreoretinopathy (PVR), a major complication of rhegmatogenous retinal detachment (RRD), is an abnormal process whereby proliferative, contractile cellular membranes form in the vitreous and on both sides of the retina, resulting in tractional retinal detachment with fixed retinal folds. Patients with RD complicated by PVR will be included, and the proposed intervention will be performed.

Procedure: 3D Pars Plana Vitrectomy associated with Extensive Brilliant Blue G-Assisted ILM Peeling Method

Interventions

After the injection of Brilliant Blue-G (BBG) into the vitreous cavity, the epiretinal membrane (ERM) with cellular proliferation on the surface of the retina did not stain clearly, while the internal limiting membranes did stain clearly. We peeled off the internal limiting membrane (ILM) underlying the ERM using the ILM forceps for the macular area and the serrated forceps for the remaining ILM beyond the vascular arcades (Grieshaber, Alcon Laboratories, Inc., Fort Worth, Texas (Figure1) and enhanced membrane viewing with filters on the Ngenuity system. Restaining with BBG was needed and perfluorocarbon liquid PFCL was injected with a coaxial Dual Bore cannula (MedOne) to flatten the retina.
