Multiple Types Late-Onset Postoperative Retinal Folds following Vitrectomy for Retinal Detachment Repair with Silicone Oil: Morphologic Variability and Optical Coherence Tomography Angiography Features - A Case Report.

Introduction: Retinal folds (RFs) may develop following rhegmatogenous retinal detachment (RRD) repair, though it consists an uncommon complication. Case Presentation: Herein, we present a case of late-onset postoperative outer RFs with aggravating characteristics following vitrectomy with silicone oil (SO) tamponade for RRD repair; early clinical findings, complications, anatomical and functional status during a 12-month follow-up period are described. Retinal imaging by acquiring optical coherence tomography scans and angiograms indicates detailed morphological and angiographic characteristics of the evolution of RFs over time. Our case provides insight into a combination of various types of RFs along with retinal disorganization with appearance in the late postoperative period after RRD repair with SO tamponade. Conclusion: Our aim was to raise awareness of the pathological processes that may be associated with the development and evolution of RFs after successful RRD repair, indicating that it is critical to accurately diagnose the type of RFs and closely monitor their progression in an attempt to provide prognostication for future visual outcomes.
