Clinical Study

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

Figure 4

The emulsified silicone oil droplets adhering to the retinal surface would be pushed into the vitreous cavity, while the air entered into the vitreous cavity. The silicone oil droplets would float up because of buoyancy and finally form a thin oil layer between the air (upper layer) and the balanced salt solution (BSS, bottom layer). At that time, the patient’s head was gradually turned temporally by approximately 90°, so that the silicone oil layer together with BSS would flow out of the eyeball through the inferior-temporal cannula due to gravity.
