To determine the frequency of postoperative macular complications in patients who underwent vitreoretinal surgery for retinal detachment with the use of silicon oil as an intravitreal tamponade agent.

Retrospective, cohort study, was carried out in which 112 patients underwent vitreoretinal surgery from January of 2021 to February of 2023 with silicone oil as a tamponade agent. All included patients had a pre- and postoperative oct-a at 1 month and 6 months after the procedure

Of 112 patients, 6.2% (N=7) presented macular complications; Of them, the average age was 63+7.3 years. 57% (N=4) were right eyes and 42% (N=3) were left eyes. 72% were men and 28% women. The average preoperative visual acuity (VA) in logMar was 1.4+0.3 and postoperative 1.2+0.2. One month after surgery, 57% (N=4) presented cystic macular edema; 43% (N=3) cystic spaces; 71% (N=5) epiretinal membrane; 57% (N=4) external band disruption.
At 6 months, 71% (N=5) presented cystic macular edema; 71% (N=5) cystic spaces; 57% (N=4) epiretinal membrane; 57% (N=4) external bands disruption.

The presence of epiretinal membranes one month postoperatively and of cystic spaces and macular edema at 6 months postoperatively associated with the use of silicone oil are complications that are associated with poor visual acuity recovery and may be indicative of early removal of silicone oil.
