PURPOSE: To report the efficacy of intraoperative optical coherence tomography in locating proliferative membranes or strands subretinally or preretinally during pars plana vitrectomy for proliferative vitreoretinopathy or old rhegmatogenous retinal detachment.
METHODS: After removing the vitreous and apparent epiretinal membranes, vitreous fluid was exchanged for perfluorocarbon. Lesions of the retinal folds or persistently detached retinas, suspected to be subretinal membrane lesions, were examined using intraoperative optical coherence tomography in three eyes with proliferative vitreoretinopathy.
RESULTS: Intraoperative optical coherence tomography showed subretinal or preretinal structures in all three patients. A subretinal structure with underlying fluid was removed through an intentional hole in a patient. In another patient, a subretinal structure without underlying fluid was not removed. In the remaining patient, the preretinal membranes detected with intraoperative optical coherence tomography could be peeled successfully.
CONCLUSION: Intraoperative optical coherence tomography examination with perfluorocarbon tamponade effectively identified the correct location of proliferative membranes or strands, namely, preretinal or subretinal. This imaging technique helps surgeons determine whether an intentional hole should be made to remove the subretinal structure during vitrectomy. Intraoperative optical coherence tomography, combined with perfluorocarbon tamponade, leads to safer and more effective surgery for proliferative vitreoretinopathy.
