Brief Summary The goal of this observational study is to investigate the effects of silicone oil tamponade on corneal endothelial cell density (ECD), morphology, and biomechanics in patients undergoing vitrectomy for retinal detachment (20 patients, 20 eyes). The main questions it aims to answer are: How does silicone oil tamponade affect corneal ECD, morphology, and biomechanics over 6 months postoperatively? Are these changes associated with variations in best-corrected visual acuity (BCVA) or intraocular pressure (IOP)? Comparison group: Researchers will compare preoperative measurements to 1-, 3-, and 6-month postoperative assessments to evaluate changes in endothelial parameters and corneal biomechanics. Participants will: Undergo preoperative and postoperative assessments (at 1, 3, and 6 months) using specular microscopy (to measure ECD, coefficient of variation, hexagonality) and Corvis ST (to evaluate biomechanical properties: Stress-Strain Index and deformation amplitude). Have BCVA and IOP measured at each follow-up visit to track clinical outcomes.
