Early versus late silicone oil removal after pars plana vitrectomy for rhegmatogenous retinal detachment in Upper Egypt

Objective: To compare the results of silicone oil removal (SOR) 2 months after vitrectomy for retinal detachment with delayed removal for 6 months or more. Study: Prospective and retrospective study. Patients and Methods: A total of 32 patients (32 eyes) in the prospective series of early SOR and 19 patients (22 eyes) in the retrospective series of late removal. The two groups were compared as to the condition of the eye at the time of SOR and 6 months following SOR. Results: Patient compliance with the scheduled time for SOR was more in the early removal series. The outcome was comparable in the two groups as to the risk of retinal re-detachment, while cataract, increased intraocular pressure, oil emulsification, keratopathy, and anterior segment inflammation were more frequently encountered at the time of removal in the late removal series, particularly when it was delayed beyond 6 months. Conclusion: A protocol of early removal of silicone oil after 2 months did not increase the risk of re-detachment, and ensured a better compliance of the time of removal. It can be particularly recommended when patients are less likely to comply with a protocol for delayed removal.
