“…In addition, it has been reported that intraocular silicone oil has an association with several complications, such as the development of cataracts, glaucoma, and epiretinal and subretinal fibrosis [ 10 ] and migration of silicone oil to extraocular muscle, as described in this report. Its emulsification and dispersion properties can explain silicone oil migration to numerous ocular structures [ 11 ].…”

We report a case of silicone oil migration to the lateral rectus muscle discovered during otherwise uncomplicated strabismus surgery in a patient with multiple previous vitreoretinal surgical interventions. A 58-year-old female underwent strabismus surgery to correct a long-standing sensory exotropia. This patient underwent numerous previous vitreoretinal surgical interventions due to a complex history of retinal detachments with subsequent repairs, including inserting and removing intraocular silicone as an endotamponade. During this procedure, silicone oil cysts were discovered firmly adhered within the substance of the lateral rectus muscle. These cysts were subsequently removed either by rupture or whole excision, and specimens were sent for pathological examination. Microscopy confirmed sections of fat necrosis of the lateral rectus muscle with areas incorporating silicone oil. Following this, a lateral rectus recession and medial rectus resection were performed, and the exotropia was satisfactorily corrected. This report highlights an unusual complication of otherwise unchallenging strabismus surgery. Intraocular silicone oil introduced during vitreoretinal surgical procedures may present as cysts embedded on extraocular muscle, thus presenting a unique finding of strabismus surgery.

“…However, various reasons for this can be postulated. One of the leading theories is that intraocular silicone oil may leak through pars plana vitrectomy ports during or following posterior segment surgery [ 10 ]. This is thought to be aggravated by postoperative spikes in intraocular pressure.…”

“…Silicone oil is commonly used for the surgical treatment of giant retinal tears and retinal detachment[ 1 ]. However, its use is associated with complications such as cataract formation, silicone oil keratopathy, emulsification with glaucoma, intraconjunctival oil inclusion cysts, subretinal oil accumulation, membrane reproliferation beneath the oil interface, and optic atrophy[ 2 ].…”

BACKGROUND We report a case of eye-penetrating injury in which a massive silicone oil migration into the patient’s subconjunctival space and orbit occurred after vitrectomy. CASE SUMMARY A 30-year-old male patient sought medical attention at Ganzhou People’s Hospital after experiencing pain and vision loss in his left eye due to a nail wound on December 9, 2023. Diagnosis of penetrating injury caused by magnetic foreign body retention in the left eye and hospitalization for treatment. On December 9, 2023, pars plana vitrectomy was performed on the left eye for intraocular foreign body removal, abnormal crystal extraction, retinal photocoagulation. Owing to the discovery of retinal detachment at the posterior pole during surgery, silicone oil was injected to fill the vitreous body, following which upper conjunctival bubble-like swelling was observed. Postoperative orbital computed tomography (CT) review indicated migration of silicone oil to the subconjunctival space and orbit through a self-permeable outlet. On December 18, 2023, the patient sought treatment at the First Affiliated Hospital of Nanchang University, China. The patient presented with a pronounced foreign body sensation following left eye surgery. On December 20, 2023, the foreign body was removed from the left eye frame and an intraocular examination was conducted. The posterior scleral tear had closed, leading to termination of the surgical procedure following supplementary laser treatment around the tear. The patient reported a significant reduction in ocular surface symptoms just one day after surgery. Furthermore, a notable decrease in the migration of silicone oil was observed in orbital CT scans. CONCLUSION The timing of silicone oil injection for an eye-penetrating injury should be carefully evaluated to avoid the possibility of silicone oil migration.

“…Some radiologists must be aware of the typical locations of SiO migration on computed tomography (CT) [8] . The SiO diffuses posteriorly and migrates into the retina and the pathways for vision (optic nerve, chiasm, and tract), and even its progression into the subarachnoidal and ventricular system [9][10][11] . One published study attempted to report the incidence of retrolaminar migration of SiO and present radiologic findings and clinical features based on unenhanced CT scans of the head [12] .…”

AIM: To describe the clinical and radiologic features of retrolaminar migration silicone oil (SiO) and observe the dynamic position of ventricular oil accumulation in supine and prone. METHODS: For this retrospective study, 29 patients who had a history of SiO injection treatment and underwent unenhanced head computed tomography (CT) were included from January 2019 to October 2022. The patients were divided into migration-positive and negative groups. Clinical history and CT features were compared using Whitney U and Fisher's exact tests. The dynamic position of SiO was observed within the ventricular system in supine and prone. CT images were visually assessed for SiO migration along the retrolaminar involving pathways for vision (optic nerve, chiasm, and tract) and ventricular system. RESULTS: Intraocular SiO migration was found in 5 of the 29 patients (17.24%), with SiO at the optic nerve head (n=1), optic nerve (n=4), optic chiasm (n=1), optic tract (n=1), and within lateral ventricles (n=1). The time interval between SiO injection and CT examination of migration-positive cases was significantly higher than that of migration-negative patients (22.8±16.5mo vs 13.1±2.6mo, P<0.001). The hyperdense lesion located in the frontal horns of the right lateral ventricle migrated to the fourth ventricle when changing the position from supine to prone. CONCLUSION: Although SiO retrolaminar migration is unusual, the clinician and radiologist should be aware of migration routes. The supine combined with prone examination is the first-choice method to confirm the presence of SiO in the ventricular system.
