[Intraoperative use of coherence tomography in vitreoretinal surgery]. / Utilidad transquirúrgica de la tomografía de coherencia óptica en cirugía vítreo-retiniana.

ABSTRACT

BACKGROUND: Optical coherence tomography is a useful tool in several diseases. Its intraoperative use with the intention of improving anatomical results has recently been described. PURPOSE: To determine the usefulness and safety of optical coherence tomography during pars plana vitrectomy for several vitreo-retinal diseases. MATERIAL AND METHODS: A prospective case series is reported, in which the decision that influenced the use of the optical coherence tomography imaging during pars plana vitrectomy is evaluated. A RESCAN 700 microscope that includes a spectral domain tomography was used to obtain the images. At the end of each procedure the surgeons completed a questionnaire to determine if the tomographic image had an influence when making decisions during the surgery, or change the decision during the procedure. RESULTS: Thirteen patients with pars plana vitrectomy were included, with cataract surgery also performed in 6 patients. The surgeon considered that the intraoperative image influenced the decision during the procedure in 8 cases. CONCLUSION: Intraoperative optical coherence tomography is helpful for a safe patient diagnosis. It does not affect the surgery time, and in some cases it is useful for optimising the procedure in vitreous-retinal surgery.
