25 g Vitrectomy for Diabetic Traction Retinal Detachment and Vitreous Hemorrhage, Nader Moinfar MD

Every retina specialist becomes skilled in the care and surgery of patients with diabetic retinopathy. This is a case of a vitreous hemorrhage, traction retinal detachment and diabetic retinopathy. This was performed near my office in Lake Mary, Florida. Patients with advanced proliferative diabetic retinopathy (PDR) can bleed into the vitreous. During this particular 25 gauge vitrectomy, I remove the vitreous hemorrhage and also expose a diabetic traction retinal detachment (TRD). The blood is actually benign, but it is not a coincidence that there is also scar tissue on the surface of the retina starting pull, or detach, the retina. This scar tissue is very vascular and these fragile blood vessels can break open and bleed. The real problem is the diabetic traction retinal detachment that is forming. This is one of 2 ways that patients with advanced diabetic retinopathy can go blind (the other is from a very specific type of glaucoma, called neovascular glaucoma). Proliferative diabetic retinopathy (PDR) results from long term damage to the small blood vessels of the retina. Basically, the retinal tissue becomes ischemic, that is, it lacks oxygen. "Ischemic" retinal tissue creates chemical growth factors that cause abnormal blood vessels to form inside the eye. Left untreated, these blood vessels and scar tissue creep along the surface of the retina and start to cause a detachment. This patient's detachment is not too bad and we were able to help by making sure the macular area stays attached. Many times a retina specialist needs to make risk/benefit decisions during surgery. The more we attempt to do, the more likely the chance of sight threatening complications. The whitish material you see is actually abnormal scar tissue on the surface of the retina. The idea is to remove the traction, or pulling, that this tissue is causing. Remember the retina is as strong as wet toilet paper so great care is taken when operating on the surface of the retina.
