Background and objective: This systematic review and meta-analysis was made to measure risk factors for retinal redetachment (re-RD) after silicone oil removal (SOR) in a quantitative method.
Patients and methods: A comprehensive literature review relating to risk factors for re-RD after SOR was conducted before March 2017. Odds ratio (OR) with 95% confidence interval (CI) was calculated after data combination.
Results: Sixteen studies were included, and risk factors with significant differences found between the re-RD and control groups are as follows: aphakic eye (OR = 1.50), high myopia (OR = 2.47), previous failed retinal surgery (OR = 1.71), and ocular trauma (OR = 3.52). Peripheral 360° laser retinopexy (OR = 0.40) and scleral encircling band (OR = 0.58) were found to be protective factors of re-RD after SOR.
Conclusion: Aphakic eye, high myopia, previous failed retinal surgery, ocular trauma, lack of 360° laser, and scleral encircling band were possible risk factors relating to the occurrence of re-RD after SOR. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:416-424.].
