Intraoperative optical coherence tomography and proportional reflux hydrodissection-guided pars plana vitrectomy for complex severe proliferative diabetic retinopathy
The study describes the technique of combining microscope-integrated optical coherence tomography (mi-OCT) and proportional reflux hydrodissection (PRH) during pars plana vitrectomy (PPV) in eyes with complex proliferative diabetic retinopathy (PDR) including tractional retinal detachment (TRD), combined retinal detachment (CRD), and taut posterior hyaloid membrane (TPHM). In this technique, PRH is used to create tissue planes between fibrovascular adhesions in areas identified using mi-OCT for insinuating the vitrector, enabling tissue dissection and release of traction. About 46 patients were operated using this technique. 34 eyes had TRD, 9 eyes had CRD, and 3 eyes were diagnosed with TPHM. A second instrument ...
