Preoperative and postoperative color fundus images and swept source optical coherence tomography. a A preoperative color fundus image shows a retinal detachment with a temporal giant retinal tear (arrowheads). b Swept-source optical coherence tomography (OCT) B-scan images obtained under intraocular gas on postoperative day 1 shows subretinal retention of two perfluorocarbon liquid (PFCL) droplets. The droplet indicated by the arrow is located under the fovea; that indicated by the arrowhead is located in the parafoveal area. c Color fundus image obtained 1 month after PFCL removal. The retina is reattached. The arrow points to the drainage retinotomy created during the first surgery, which was used to extract the subretinal PFCL droplets to the retinal surface. d OCT B-scan image obtained 1 month after PFCL removal shows resolution of the subretinal PFCL. The outer retinal microstructure of the fovea is not completely restored, but visual acuity was 20/40 (arrow)
