Early Prevention Strategies of Severe Proliferative Vitreoretinopathy Base on Precision Diagnosis of Single Cell Sequencing

Study of initiating proliferative vitreoretinopathy (PVR)cell subtype (PVR initiating cells (PVR-IC) in RPE cells of rhegmatogenous retinal detachment (RRD) patients; to prove the percentage of PVR-IC decides the risk of serious PVR occurring after surgery; to investigate the safety and efficacy of early local steroids drug intervention in patients with severe postoperative PVR.
