In fact, silicones have a critical surface tension of wetting that is higher than their own surface tension. This activity is supported by an unrestricted educational grant from Allergan. Processing. Scheerlinck LM, Schellekens PA, Liem AT, Stejins D, vanLeeuwen R. Incidence, risk factors, and clinical characteristics of unexplained visual loss after intraocular silicone oil for macula-on retinal detachment. By varying Selection of oil type may depend on the individual case. Miller JB, Papakostas TD, Vavvas DG. In eyes with iris loss (such as in trauma), iris retention sutures have been described to create a barrier between the oil and the anterior chamber.7 Finally, postoperative facedown positioning will help keep the oil confined to the posterior segment. Timing of oil removal is best planned in an individualized manner. Vision loss associated with the use and removal of intraocular silicone oil.

Berrocal, MD, Treating Retinal Disorders: Updates for the Newer Retina Specialist. USA.gov. Ensuring adequate oil fill and avoiding overfill are important for preventing complications. Br J Ophthalmol. Additionally, silicone oil volume is unaffected by atmospheric pressure, so it may be used in patients who must undertake high altitude travel.3. Both 1,000 cs and 5,000 cs oil have similar surface tensions (21.2 mN/m and 21.3 mN/m, respectively) but differ in molecular weights (37 kDa and 65 kDa, respectively) and viscosities.3, In a review of 325 eyes with complex retinal detachment, no differences were observed in anatomic or visual outcomes between 1,000 cs and 5,000 cs oil.5 A similar review of 82 eyes found no significant differences between the two groups with respect to outcomes or complication rates at 1 year.4 However, higher viscosity silicone oils (5,000 cs) are more resistant to emulsification over time.5, With the use of small-gauge cannulas during vitrectomy surgery, injection and removal of the higher viscosity 5,000 cs silicone oil becomes more difficult. Add the silicone oil to the silicone mixture. Epub 2018 Mar 19.  |  Tamponade in the surgical management of retinal detachment. 13. Direct PFO-oil exchange requires use of chandelier illumination unless an assistant is present. eCollection 2016. For this reason, it is important to counsel patients regarding the risk of redetachment and the possible need for chronic oil tamponade. Because of the risk of complications from retained oil droplets, complete removal is desirable insofar as it is possible. • Associate Professor of Ophthalmology, University of Washington, Seattle, Washington • Retina Fellow, University of Washington, Seattle, Washington Finally, the saline solution is flushed through the anterior chamber to remove any hidden oil droplets from the angle or from behind the iris.
