Subretinal Perfluorocarbon
Clinical Features:
Subretinal PFC liquid appears as a localized spherical elevation of the retina (Fig. 12.5.1). The location of the subretinal PFC depends on how the PFC made its way under the retina intraoperatively. If the macula is involved, central visual acuity can be adversely affected.
OCT Features:
OCT through a subretinal PFC liquid droplet reveals a hyporeflective cavity similar in density to the vitreous space (Fig. 12.5.2). The overlying retina is thin due to a mechanical effect of the dense liquid. Sometimes, it can appear as if the PFC liquid is within the retina, though it is actually underneath (Fig. 12.5.3).
Figure 12.5.2 OCT through the subretinal PFC liquid droplet (corresponding to Figure 12.5.1) shows a completely hyporeflective space occupied by the PFC. There is a distinct rim of hyper-reflectivity. The overlying retina is very thin due to a mechanical effect of the dense liquid. (Courtesy of Caroline Baumal, MD.).
