The Sutureless vitrectomy is considered as one of the most popular pars plana vitrectomy, because this technique is included among some of the surgeries which include minimally invasive surgical procedure. Silicone oil is referred to as a liquid which possesses unique properties related to surface tension. This liquid is considered to be widely utilized as an internal tamponading agent during diversified ophthalmological surgical procedures, specifically for the retinal attachment surgery. Procedures related to the removal of silicone oil might enhance the risk of retinal detachment along with other severe complications. Potential complications associated to silicone oil removal might be dependent on diversified other factors, including viscosities of silicone oil, time elapsed between pars plana vitrectomy and need for silicone oil removal. This research carried out in three eye care centres in Jordan analyzed and compared visual outcomes of two different types of silicone oils having different viscosities (10000cs and 5000cs) after removal in eyes having stabilized retina after the completion of vitreoretinal procedures for retinal detachment. Research outcomes demonstrated that the re-detachment rates associated to the 5000 cs silicone oil were higher as compared to 1000 cs silicone group. Research outcomes also demonstrated that poor functional, as well as anatomic outcome, was found to be strongly associated to the utilization of high viscosity silicone oil (5000 cs) as compared to the low viscosity silicone oil (1000 cs).
