RRD is a serious dynamic sight-threatening disease that occurs in 1 to 10,000 people per year in the general population managed as an emergency that requiring intervention specially when the macula is still on.(1) So, a timely repair of RRDs is critical with proper choice of surgical plan, the appropriate retinal tamponade if PPV is used and the post-operative positioning, follow up scheduling, IOP control and finally time to remove the silicone oil when used as a retinal tamponade after successful reattachment. Several histopathological and clinical studies reported the penetration of silicone oil into the ocular structures affecting nearly all retinal layers by different direct and indirect pathogenesis specially after the introduction of the optical coherence tomography (OCT) in clinical practice which enabled objective and quantitative analysis of different retinal layers.(2)
We chose in this study to analyze in particular the average RNFL thickness changes course after silicone oil removal using SD-OCT and if a significant change could be noticed over follow up period of 3 months after silicone oil removal.
