One of the drawbacks of using perfluorocarbon liquid for retinal detachment repair is the risk of retained PFCL bubbles. When small and in either the vitreous cavity or in the peripheral subretinal space, these PFCL bubbles often can be observed. However when it is in the macula, and particularly when it is subfoveal or juxtafoveal, retained PFCL may cause RPE and photoreceptor toxicity, inflammation and fibrosis and may cause visual scotomas and distortions. In these scenarios, how do you remove subfoveal or perifoveal PFCL bubbles? In today’s episode we will show you one technique; performing transretinal PFCL removal using a soft tip cannula and passive extrusion.
