|A||Removal of epiretinal membrane|
1. Removal of epiretinal membranes is the one of the basic principles of surgery in diabetic retinopathy.
2. It is essential to remove all the membranes and thus release of traction bands which lead to tractional retinal detachment most commonly seen in diabetic retinopathy.
3. Vitrectomy is indicated in cases of nonresolving vitreous hemorrhage and retinal detachment to clear the opacities and also to release the vitreous traction bands
4. Photocoagulation is the standard treatment modality in diabetic retinopathy whether endo or exo, in form of panretinal photocoagulation or focal laser or macular grid etc
5. The use of internal tamponade agents like silicone oil and intraocular gases is controversial as the main aim of the surgery in diabetic retinopathy is to remove all the traction bands which r responsible for retinal detachment.
