Purpose: To evaluate complications with silicon oil in vitrectomized patients with Posterior Vitreous Detachment (PVD) Design: Retrospective, transversal Methods: This is a retrospective and transversal study, where we review 193 vitrectomies and PVD patient files at the Department of retina, and included 26 files. All the patients were interviewed and checked in the Retina Department at the Nuestra Señora de Luz Hospital looking for complications such as elevated intraocular pressure, retina and corneal changes, during a four year period. Results: The complications founded were distributed as follows: elevated intraocular pressure (28.7%), corneal changes (14.28%), and perisilicon proliferations (4.76%). 33.33% required silicon oil extraction. Conclusion: Intraocular pressures were found much more frequently in our patients than in previous reports, As has been observed by others authors, many of the complications reported here did not occur until after the 3-month follow up visit. If the oil is to be removed, we suggest to be done within 3 months of the initial procedure of instillation. If oil is to be used as a permanent tamponade, then a highly biocompatible oil must be used. Clinical studies comparing tissue effects of oils from various origins would be useful in determining biocompatibility. We believe silicone oil is an important adjunct in the treatment of complicated vitreoretinal problems and because of its optical clarity and high surface tension, is often an indispensable tool in meticulous microsurgery of the retina.
