A 73-year-old woman with macular pucker underwent a pars plana vitrectomy with membrane peeling. Additionally the patient suffers from diabetic retinopathy after being diagnosed with type 2 diabetes mellitus sixteen years ago. Prior to the procedure she was treated with a series of intravitreal Bevacizumab-injections due to diabetic macular edema. There was no history of a proliferative DRP. During the vitrectomy a branch of an obliterated NVE spontaneously detached and floated freely in the vitreous. The 3D shot was captured via Alcon’s NGENUITY® 3D Visualization System in form of photograph and video providing an outstandingly detailed image of the branched NVE.

Peri-papillary vascular loops (PVL) are rare congenital vascular malformations, which are usually detected as accidental finding during routine fundus examination. They can often be confused with tributary vein occlusion or racemose hemangioma. Although benign and asymptomatic, they can be rarely associated with vitreous hemorrhage and arterial occlusion. We herein present a case of a 60-year-old hypertensive male, who was diagnosed elsewhere to have a tributary vein occlusion and was referred to us. FFA was advised to rule out neovascularization, surrounding capillary non perfusion and mass lesion (hemangioma). On FFA, the arterial loop showed a slightly delayed filling (3-5 seconds) as compared to the other arterial vessels and the original vessel appeared to be a branch arising from central retinal artery. The choroidal filling was delayed in the area supplied by the loop. A cilioretinal artery was also noted. The patient was diagnosed to have a Peri-papillary vascular arterial loop (PVL), likely to be congenital in origin. The patient was reassured and was advised yearly follow up. These loops are usually accidental findings discovered during routine fundus examination. Since these vessels are looped and tortuous, they exhibit a slower and laminar blood flow, which make them more prone for arterial occlusions. The vitreous in this area tends to be adherently attached, so during PVD induction, it is likely to cause a tear and hemorrhage leading to vitreous hemorrhage. Until and unless there is a break, this hemorrhage tends to resolve on its own and does not warrant treatment. If there is an evident break, it can be dealt with laser barrage.

Vitrectomy is carried out for epiretinal membrane removal. After doing core vitrectomy and pvd induction a 25 gauge forceps is used to pinch and peel the macular pucker. After finding a edge the forceps is gradually moved tangentially over the retinal surface to remove the membrane.

This is a case of Macular hole for which vitrectomy is being done. After doing core vitrectomy triamcinolone dye is injected to stain the hyaloid. High aspiration is used on cutter to engage the hyaloid and gradually pull it anteriorly. PVD induction is carried out. After this brilliant blue dye is injected to stain the internal limiting membrane. ILM is peeled using a 25 gauge forceps in a tangential manner. After this i use a instrument called the massager which we have developed to gently and atraumatically massage concentrically the edges of the hole. This releases the subtle contaction on the edges of the hole and relaxes the margins. After this air fluid exchange is carried out followed by low vacuum aspiration over the hole. The hole approximates itself gradually as the aspiration dries up the edges.
