Purpose: To study the effect of retained subretinal perfluorocarbon liquid (PFCL) on retinal function. Methods: Scanning laser ophthalmoscope (SLO) microperimetry was performed on four eyes with retained subretinal PFCL following vitreoretinal surgery for complicated retinal detachments. Results: Scotomata to the highest intensity stimuli were noted in the area of the subretinal PFCL in all four eyes. In one eye in which there was migration of the PFCL droplet during the post–operative period, a relative scotoma was found in the area vacated by the migrating PFCL bubble. All scotomata encompassed the same area as the retained PFCL droplets. Conclusions: Subretinal PFCL can cause local reduction in the sensitivity of the retina, as demonstrated by SLO microperimetry. There may be partial recovery of retinal function in an area vacated by a migrating PFCL bubble. Because of the risk of visual loss, consideration might be given to removal of a PFCL bubble beneath or threatening the fovea.
