31 patients were included in the study,15 cases with ERM in silicone filled eyes and 16 eyes with idiopathic ERM
Full description
This is a prospective study that included 31 patients and was performed in Tanta University Eye Hospital in cooperation with the Pathology Department, Tanta University, between January 2018 and June 2019. The approval of the ethical committee of the Faculty of Medicine in Tanta University was obtained, and the study was conducted in accordance with the 1964 Helsinki Declaration and its later amendment. A detailed informed written consent was signed by all study participants. The research is not funded by the university or any organization or entity.
Fifteen cases had pars plana vitrectomy for rhegmatogenous retinal detachment nine months earlier with ERM detected by OCT one day before silicone oil removal. The other 16 cases matched for age and gender with idiopathic ERM and were included as a control. Histopathological features of the ERMs were compared between the two groups.
All patients have undergone complete ophthalmic evaluation including: best corrected visual acuity (BCVA) by Snellen chart that was converted to log MAR for statistical analysis, anterior segment examination by slit lamp, posterior segment examination by slit lamp bimicroscopy using +78 D lens and indirect Ophthalmoscopy, and Spectral domain optical coherence tomography (SD-OCT) (Spectralis; Heidelberg Engineering,Heidelberg, Germany) was performed for all patients before surgery.
The investigators excluded patients with previous intraocular surgery (except cataract surgery) for the control group, diabetes mellitus/diabetic retinopathy, coincident retinal pathology as choroidal neovascular membrane and age related macular degeneration, previous laser photocoagulation, intravitreal injection of Triamcinolone Acetonide or antivascular endothelial growth factor (anti-VEGF) agents, prior intra-ocular inflammation, retinal degenerations, neovascularization or rubeosis and vascular disorders e.g. retinal vein or artery occlusion.
