Aim:
To evaluate the functional outcome after removal of silicone oil (ROSO) in patients undergoing retinectomy for complex retinal detachment.
Methods:
We performed a retrospective case note review of patients who underwent ROSO after retinectomy for complex retinal detachment. Patients with less than 6mo follow up and recurrent retinal detachment following ROSO were excluded.
Results:
Thirty-six patients were included. The mean best corrected visual acuity (BCVA) pre-ROSO was 1.13 logMAR (SD 0.5). The mean BCVA 3mo following ROSO was 1.16 logMAR (SD 0.53), 6mo following ROSO 1.13 (SD 0.63), and 12mo following ROSO 1.18 (SD 0.69). At 12mo after ROSO, the BCVA improved in 38.9% of patients, remained unchanged in 25%, and deteriorated in 36.1%, although there was no statistical significant difference in BCVA after ROSO at 3, 6 and 12mo (P=0.93). The size of retinectomy ranged from 15° to 270° (SD 53) and did not influence the visual outcome (P=0.11).
Conclusion:
There was no statistically significanT difference in BCVA between pre- and post- ROSO following retinectomy for complex retinal detachment. There was no statistical difference in visual outcome related to the size of the retinectomy.
