Retinal detachment is one of the leading causes for permanent vision loss.Incidence of Rheugmatogenous Retinal Detachment (RRD) about 10.5 people per 100,000 population pars plana vitrectomy is the most popular and effective surgical options.
Tamponade agents as silicone oils are used to restore intraocular volume and apply surface tension to the detached retinal surface Silicone oil (SO) is a liquid containing polymerized siloxane with organic side chains. It has a high thermal stability, is hydrophobic, and chemically inert. The use of silicone oils as intraocular tamponades dates from 1962.
None
Patients with history of previous intraocular surgery.
Patients with combined traction-rhegmatogenous retinal detachment
Patients with ocular disease as glaucoma ,degenerative myopia,age related macular degeneration
Patients with poor fixation.
Single group
Multi focal electroretinogram
Deviceto evaluat the effect of silicon oil on retinal function in the eyes that underwent Pars Plana Vitrectomy with Silicon oil tamponade for Rheugmatogenous Retinal Detachment. mfERG responses were recorded before and after Silicon oil removal .
Retinal Functions after vitrectomy
Evaluation of the Function of the Eye Retina after Vitrectomy for all the participants
Electroretinogram Examination after vitrectomy
Electroretinogram examination which performed for all eyes after the vitrectomy as:When the light hits the eye, the photoreceptors (rods and cones) and other retinal cells generate small electrical impulses. The Electroretinogram captures and graphs these impulses to evaluate if these cells are functioning normally or not.
