Methods: Retrospective, cohort study. Patients who underwent retina surgery with SO injection and extraction in our center were included. We compared the complication rates of ME, OHT, emulsification and migration to the AS according to SO type (1300cSt, 5700cSt and heavy SO). Data on age, sex, emulsification time, duration of the tamponade, previous retina surgeries and diagnosis were also gathered and included in a multivariate analysis. Results: We included 163 patients (mean age of 64.8 years; mean duration of the tamponade: 11 months). Rates of emulsification, ME, OHT and SO migration to the AC were similar in all groups (p = 0.998, 0.668, 0.915 and 0.360). ME was the most frequent complication (33.3-47.8%), which resolved after SO extraction in 77.6% of cases. The majority of cases with OHT persisted (61.7%). Emulsification was related to younger age (OR 0.94) and longer duration of the tamponade (OR 1.04). The odds of SO migration to the AC increased with emulsification (OR 2.78), recurrent retinal detachment (OR 0.99) and aphakia (OR 4.05). Conclusions: We propose SO extraction as the preferred treatment for ME during SO tamponade. SO extraction should be performed sooner in younger patients to avoid emulsification. In selected patients, we suggest a longer duration of the tamponade up to 11 months with a reasonable safety profile, regardless of the SO type.enrestricted accessDesprendimiento de retinaRetinal detachmentSiliconas - Efectos adversosSilicones - Side effectsArtículohttps://doi.org/10.1177/11206721231200034https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es
