Objective: To evaluate the incidence of retinal re-detachment after silicon oil extraction.
Material and methods: A retrospective, single-center study was performed on a case series of patients with retinal detachment operated between January 2013 to December 2020 at Centro de Ojos Quilmes (Buenos Aires, Argentina) by pars plana vitrectomy with silicone oil and subsequent extraction, with at least 6 months of follow-up. We evaluated the number of eyes with new detachments after oil extraction and in addition, the time elapsed, characteristics of the detachments, type of oil used, intraocular pressure, lens status, and pre-existing ocular pathologies.
Results: We included 109 eyes of 107 patients. After 6 months following oil extraction, the retina remained attached in 75 eyes (68.8%) and was re-detached in 34 (31.2%). The mean time between the initial interval and removal, in the re-detachment group was 8.2 ± 5.2 months (2-24) and in the group of eyes without re-detachment was 8.7 ± 8.1 months (2-60) (p=0.69). The re-detachments occurred with a mean time of 2.9 ± 8.4 months (0-48), but in 19 eyes (54.3%) it occurred within the first month and in 17 between the second and third month (37.2%).
Conclusion: The incidence of retinal re-detachments after silicone oil extraction was 31.2%, occurring mostly in the first trimester and more than half in the first month.
