2018 Jun;32(3):204-210. doi: 10.3341/kjo.2017.0050. J Glaucoma. Used gas bubble before and it worked great. Viscosity and molecular weight are two important physical factors affecting the rate of emulsification. However, overall visual acuity improved for oil-removed eyes in 19 (29%) of 66 pairs and for oil-retained eyes in one (2%) of 66 pairs (OR, 19.0; P < .0001). One study showed normalization of IOP after removal of oil in 93% of patients,25 and another study showed persistent elevated IOP after oil removal.26 Persistent IOP elevation may be explained by small remaining emulsified oil droplets continuing to obstruct the trabecular meshwork or by persistent inflammation.21, Emulsified silicone oil can cause retinopathy, which is becoming more evident with new imaging modalities. If its moving all over the place - it may be doing more harm than good at this point. • Less viscous silicone oils emulsify earlier than oils with higher viscosities. Understanding the forces and factors that lead to silicone oil emulsification is crucial to minimizing its occurrence. Subgroup analysis of the Silicone Study, a randomized, multicentered, surgical trial. • The adoption of small-gauge vitrectomy has led to the increased use of low-viscosity silicone oils. Intrinsic surfactants are biologic elements released in the setting of inflammation and hemorrhage. Used silicone oil so I could fly to Hawaii for planned 65 th birthday (hers) can’t fly with gas bubble which is the way to go otherwise But no flying! Shear forces during aqueous and oil movement may also promote emulsification. I have had silicone oil in my eye post-op retinal detachment surgery for the past 2-years now. To evaluate the outcome after silicone oil removal, retinal redetachment, visual acuity, and complications were analysed. 2012;32(10):2039-2044. ***this post is edited by moderator *** ***, Retinal Detachment after Intravitreal Injection: When Macular Degeneration Treatment Fails. Tamponade in surgery for retinal detachment associated with proliferative vitreoretinopathy. Anti-VEGF Update: When is Switching Patients Acceptable and Preferable? Intraocular pressure and silicone oil endotamponade. Ichhpujani P, Jindal A, Jay Katz L. Silicone oil induced glaucoma: a review. 8. The intraocular pressure was normal, and the lens was covered with pigmentary deposits. 1962;68:590-599. Although nonsignificant, incidence rates of keratopathy (OR, 0.5) and hypotony (OR, 0.5) were lower in oil-removed eyes. 10. 1998;18(3):228-32. doi: 10.1097/00006982-199803000-00006.

Federman JL, Schubert HD. My current vision with the silicone is 20/100-200. We offer this Site AS IS and without any warranties. 24. Since i am about to have my silicone oil removed after retinal detachment surgery. Heidenkummer HP, Kampik A, Thierfelder S. Emulsification of silicone oils with specific physicochemical characteristics. If silicone is endangering your cornea - then you may might need to have it removed. The emulsified SO layer moved as the patient tilted his head. We disclaim all responsibility for the professional qualifications and licensing of, and services provided by, any physician or other health providers posting on or otherwise referred to on this Site and/or any Third Party Site. The Silicone Study established the efficacy of SO in a randomized, controlled clinical trial that compared 1000-centistoke SO to 14% C 3 F 8 and 20% SF 6 in patients with retinal detachment and grade C3 or greater PVR. Ophthalmic Surg. (this is the seeing part of the retina). Miller JB, Papakostas TD, Vavvas DG. These changes persisted at 6 months, at which time an additional three eyes showed emulsified oil droplets between the hyperreflective line of oil and the optic disc.30 The long-term impact of emulsified silicone oil in these locations is unknown. The ICD-10 code H35.371 (Puckering of macula, right eye) is used on the claim. 1987;18(6):446-449. Please enable it to take advantage of the complete set of features! Silicone Study report 11. Corneal decompensation may occur when silicone oil comes in contact with the corneal endothelium.15 Silicone oil–induced keratopathy is marked by decreased endothelial cell density, pleomorphism of remaining endothelial cells, resulting corneal edema and bullous keratopathy, stromal hypercellularity, superficial stromal calcification, and retrocorneal membrane formation.16 These findings are not limited to emulsified silicone oil. Br J Ophthalmol. Dresp JH, Menz D-H. Interaction of different ocular endotamponades as a risk factor for silicone oil emulsification. 1 It has become the preferred tamponade agent in cases at high risk for recurrent retinal detachment, such as in eyes with retinal detachment associated with severe proliferative vitreoretinopathy (PVR) or with detachment resulting from viral retinitis. Guest It sounds like silicone is getting forward into the front chamber of the eye. De Corral LR, Cohen SB, Peyman GA. Effect of intravitreal silicone oil on intraocular pressure. Al-Jazzaf AM, Netland PA, Charles S. Incidence and management of elevated intraocular pressure after silicone oil injection. My current physician is advising me to have it taken out due to future complications of decomosition of the cornea. Dr. Papakostas may be reached at thanosp@me.com. Compared with the eyes that did not undergo silicone oil removal (oil-retained eyes) evaluated at a comparable time after oil injection, oil-removed eyes at the examination prior to oil removal were more likely to be attached (85% vs 40%; P < .0001), have a visual acuity of 5/200 or greater (63% vs 35%; P < .0001), and not be hypotonous (5% vs 22%; P < .001). 28. After surgery it is usually necessary to posture face down for 12 to 24 hours, or longer in certain cases. Surfactants may be intrinsic or extrinsic. I have been able to get it back where it belongs (in the backside of the iris) al three times, usually within a day sometimes 2. Find NCBI SARS-CoV-2 literature, sequence, and clinical content: https://www.ncbi.nlm.nih.gov/sars-cov-2/. Thank you for any replies. It can be done under local anaesthetic. Hyperreflective dots on OCT (yellow arrows) demonstrate silicone oil droplets within the macular hole (D). Arch Ophthalmol.

Of all factors studied, the duration of silicone oil in the eye has the strongest correlation with the occurrence of emulsification. Azuara-Blanco A, Dua HS, Pillai CT. Pseudo-endothelial dystrophy associated with emulsified silicone oil.
