SYMPTOMATIC MIGRATION OF SILICONE OIL TO THE VENTRICULAR SYSTEM.

Purpose: The objective of this article is to report a case of silicone oil migration into intraocular packing in cases of retinal detachment, while reviewing the existing literature on the various mechanisms and locations of this migration. However, it is important to highlight that the use of this material is not free from complications.

Method: This article is a case report with a literature review. The information was obtained through a review of the medical record, interview and photographic record of the patient's diagnostic methods. PubMed was used as a database to perform the search for selected articles and literature review, selecting articles published from the year 2016.

Results/discussion: The exact mechanism of migration of intraocular silicone oil to the central nervous system is still unclear, being a rare complication that may be related to several factors. We report a case in which the patient underwent vitrectomy surgery and, after several years, presented a complication related to the migration of intraocular silicone oil to the right frontal horn and third ventricle, causing headache. Conclusion: Knowledge about migration of intraocular silicone oil into the central nervous system (CNS) is extremely important, since it manifests itself in several clinical and radiological findings, which can lead to incorrect diagnoses. Thus, it is suggested the follow- up of the patient after introduction of silicone oil to avoid complications that threaten results.
