A representative case of OCTA in silicone oil (SO) tamponade eyes. A 53-year-old female patient with macula-on RRD in her right eye achieved reattachment in one shot. The period for SO in suit lasted for 4.5 months. The preoperative best-corrected visual acuity (BCVA) was LogMAR 0.22 (Snellen equivalent 20/33). The intraocular pressure (IOP) was 13 mmHg. Postoperatively, the BCVA decreased to LogMAR 0.52 (Snellen equivalent 20/67), the IOP was 19 mmHg. The patient complaint of a history of IOP elevation, with a limit high to 32 mmHg for 2 weeks. A significantly decreased parafoveal vessel density (VD) of superficial vessel complex was found in the affected eye, compared with the fellow eye. a the 6 × 6 mm en face angiogram in the affected eye: left: the deep vessel complex (DVC); right: the superficial vessel complex (SVC); b the 6 × 6 mm en face angiogram in the contralateral eye: left: the SVC; right: the DVC; c the 6 × 6 mm false coloring angiogram in the affected eye: left: the DVC; right: the SVC; d the 6 × 6 mm false coloring angiogram in the contralateral eye: left: the SVC; right: the DVC; e the OCT B scan image with layered boundary details in the affected eye: left: the DVC; right: the SVC; f the OCT B scan image with layered boundary details in the contralateral eye: left: the SVC; right: the DVC
