Purpose:
To report images of retained perfluorocarbon liquid (PFCL) on the surface of the retina obtained during an intraoperative use of hand-held spectral domain optical coherence tomography.
Methods:
A 54-year-old man underwent pars plana vitrectomy with injection of PFCL to repair retinal detachment. Postoperatively, visually significant PFCL droplets were found to be retained in the eye. During the surgical removal of PFCL, a hand-held spectral domain optical coherence tomography was used to image the retina with the patient supine.
Results:
Spectral domain optical coherence tomography images of the retained PFCL illustrated magnification of the areas of the outer retina underlying PFCL bubbles. The images obtained had some similarities to the patient's own observation of "floaters."
Conclusion:
Droplets of PFCL over the retina result in imaging artifact, most likely due to a lensing effect caused by differences in refractive index between the PFCL and vitreous humor. Although the utility of hand-held spectral domain optical coherence tomography for infants has previously been established, this case presents further application of spectral domain optical coherence tomography in adults when imaging in the supine position is required.
