Background Each of the silicone oils 1000, 2000, and 5000 cs has its own advantages and complications. Patients and methods This study included 42 eyes that were subjected to vitreoretinal surgeries with a silicone oil injection. Patients were divided into three groups: group A included 14 eyes injected with silicone oil 1000 cs, group B included 14 eyes injected with silicone oil 2000 cs, and group C included 14 eyes injected with silicone oil 5000 cs; injections were administered through the pars plana approach. Results Silicone oil 5000 cs showed the best visual outcome and resulted in more complications (except emulsification as it emulsified less). Silicone oil 1000 cs showed the less visual outcome and fewer complications. Silicone oil 2000 cs showed good visual outcome and resulted in many complications that were intermediate between the other two viscosities. Conclusion Silicone oil 5000 cs is considered the most successful retinal tamponade. However, low-viscosity silicone oils are preferred sometimes because surgical injection and removal from the vitreous cavity are easier, and fewer complications are caused by these oils, such as cataract and increased intraocular pressure.
