“…Some investigators have identified young age and macula-on retinal detachments associated with GRT as possible risk factors for an un-explained visual loss following SO removal [18, 27, 30]. In contrast our current series did not confirm these associations.…”

PurposeTo report the incidence and clinical features of patients that experienced un-explained visual loss following silicone oil (SO) removal.MethodsMulticenter retrospective study of patients that underwent SO removal during 2000–2012. Visual loss of ≥2 lines was considered significant.ResultsA total of 324 eyes of 324 patients underwent SO removal during the study period. Forty two (13%) eyes suffered a significant visual loss following SO removal. Twenty three (7.1%) of these eyes lost vision secondary to known causes. In the remaining 19 (5.9%) eyes, the loss of vision was not explained by any other pathology. Eleven of these 19 patients (57.9%) were male. The mean age of this group was 49.2 ± 16.4 years. Eyes that had an un-explained visual loss had a mean IOP while the eye was filled with SO of 19.6 ± 6.9 mm Hg. The length of time that the eye was filled with SO was 14.8 ± 4.4 months. In comparison, eyes that did not experience visual loss had a mean IOP of 14 ± 7.3 mm Hg (p < 0.0002) and a mean tamponade duration of 9.3 ± 10.9 months (p < 0.0001).ConclusionsAn un-explained visual loss after SO removal was observed in 5.9% of eyes. Factors associated with this phenomenon included a higher IOP and longer SO tamponade duration.

“…Out of 16 articles reviewed, the findings of 11 articles were meta-analyzed [ 13 – 18 , 20 , 22 – 25 ]. The findings of the other five articles are presented only quantitatively due to the lack of necessary information in the statistical analysis [ 5 , 6 , 19 , 21 , 26 ]. Of the selected articles, 13 studies were retrospective, two were prospective, and one was cross-sectional.…”

“…The long-term SO tamponade complications include secondary glaucoma, cataract, optic neuropathy, band keratopathy, and retinal toxicity [ 4 ]. Mild vision loss may occur after SO removal, usually due to postoperative cystoid macular edema (CME), hypotony, optic neuropathy, and development of epiretinal membranes; nevertheless, there are some cases of visual loss that do not have a certain cause [ 4 – 6 ] The possible mechanisms include macular dysfunction, mostly of ganglion and bipolar cell synapses, and optic nerve damage due to SO infiltration [ 5 ].…”

Background To evaluate the effects of intravitreal silicone oil (SO) on the retinal and choroidal thickness in eyes with rhegmatogenous retinal detachment (RRD). Methods A literature search was performed in Web of Science, Scopus, ProQuest, Embase, Clinical Key, Science Direct, Cochrane Library, and Springer, as well as Persian databases, including IranDoc, MagIran, SID, MOH thesis, and MOH articles until June 2020. Two reviewers independently searched and extracted the data. Results Sixteen studies (n = 391) met the inclusion criteria. The meta-analysis showed that the SO tamponade could significantly reduce the central macular thickness (CMT) in patients with RRD as compared to gas tamponade WMD = − 14.91; 95% CI: − 22.23, − 7.60; P < 0.001, I2 = 71%). No significant change was found in CMT between the eye with SO tamponade (after SO removal) and the fellow healthy eye in patients with RRD (WMD = − 3.52; 95% CI: − 17.63, 10.59; I2 = 68.6%). Compared to the preoperative stage, the SO tamponade could significantly reduce the subfoveal choroidal thickness in patients with RRD (WMD = − 18.67, 95% CI: − 30.07, − 1.28; I2 = 80.1%). However, there was no significant difference in the subfoveal choroidal thickness before and after SO removal (WMD = − 1.13, 95% CI: − 5.97, 3.71; I2 = 87.6%). Conclusion The SO tamponade had a significant effect on the reduction of retinal layers and the subfoveal choroidal thickness.

“…Rarely, central vision loss has been reported in series of patients after silicone oil removal. 3–6 For these reasons, some patients may be hesitant about having the silicone oil removed from the eye if they are not experiencing side effects, such as keratopathy or elevated intraocular pressure. In the case of our patient, the oil remained in the eye for more than 20 years.…”

Purpose: To report the clinicopathologic correlation and biochemical analysis of silicone oil removed after 23 years in an eye.Methods: A 63-years-old man with a history of HIV/AIDS and cytomegalovirus retinitis, status post retinal detachment repair with silicone oil at the age of 39 years, presented with several weeks of worse vision. He was found to have a shallow fovea-off tractional retinal detachment. After the silicone oil was removed during retinal detachment repair, it was analyzed by Fouriertransform infrared spectroscopy and gas chromatography with mass spectrometry.Results: In addition to cyclic and linear silicone oil, cholesterol was found in the removed silicone oil, which was not present in unused silicone oil samples. No other chemical alterations were identified in the extracted silicone oil.Conclusion: Silicone oil left inside an eye over an extended period may extract lipophilic substances from adjacent tissue, with possible pathophysiologic effects. However, no other major potentially toxic substance was identified from the long-standing silicone oil sample, suggesting relative chemical stability of the tamponade agent over time.
