Passive Removal of Silicone Oil with Temporal Head Position through Two 23-Gauge Cannulas

الملخص EN

Purpose.

To report a new approach for removal of silicone oil.

Methods.

All surgeries were performed using 23-gauge vitrectomy system with two transconjunctival sutureless cannulas.

At the beginning, most of the silicone oil was removed by traditional microinvasive vitrectomy system through inferior-temporal cannula.

Then, the blood transfusion tube is removed from the inferior-temporal cannula, and the fluid-air exchange is performed.

A passive fluid-air exchange was performed to aspirate the residual silicone oil after gradually turning the patient’s head temporally by approximately 90° gradually.

Results.

After the surgery, all patients had a clear anterior chamber and vitreous cavity on slit lamp and B scan examination, respectively.

The mean time taken for silicone oil removal and total surgery was 8.0 ± 1.4 minutes and 12.4 ± 2.5 minutes, respectively.

The mean intraocular pressure 1 day, 3 days, 1 week, 1 month, and 3 months after surgery was 9.0 ± 5.8 mmHg, 11.3 ± 7.6 mmHg, 16.1 ± 6.9 mmHg, 17.7 ± 4.8 mmHg, and 17.1 ± 3.5 mmHg, respectively.

Conclusion.

This new approach may provide a safe and fast method to remove the silicone oil.
