ABSTRACT Introduction: Suprachoroidal Hemorrhage (SCH) is a potentially devastating complication of both anterior and posterior segment surgery. Although rare, it can occur following corneal transplants, glaucoma or cataract surgery, and vitreoretinal surgery or trauma. SCH may occur when a fragile vessel is exposed to sudden compression and decompression forces. Systemic risk factors include advanced age, arteriosclerosis, hypertension and...

Managing Giant Retinal Tears 2 Cases Report ABSTRACT Introduction: Retinal detachments with giant retinal tears (GRT) pose a significant challenge, even to the most experienced vitreoretinal specialists. The extent of the primary lesion complicates management and tamponade choices, carrying the risk of the flap folding over post-operatively and re-detaching the retina. The authors present two cases of a retinal detachment with giant...

Introduction: Full-thickness idiopathic macular holes are foveal anatomic defects with a complete interruption of all retinal layers. This results in a significant visual impact for the patient. Current surgical options are constantly under debate, particularly after the new International Vitreomacular Traction Study Group classification. Various surgical options have been proposed to boost the closure rates in this disorder, namely...
Read MoreEntry-site Hemorrhage: When to Suspect and How to Manage it
Introduction: Vitreoretinal sutureless surgery has evolved in recent years into a safer, more effective group of procedures. It is, therefore, an unexpected sight to have a vitreous hemorrhage at the end of an otherwise uneventful vitrectomy. A possible cause of such a finding is an external hemorrhage that occurs immediatly after the removal of the trocars, that finds its way inside the vitreous cavity through the sclerotomy. Methods: The...

Introduction: Any surgical pathology presenting with concomitant inflammation presents a dilemma to the eye surgeon, due to the increased risk of post-op complications. On the other hand, a retinal detachment presents an additional challenge to the vitreoretinal specialist in this situation. The authors present a clinical case with both these simultaneous conditions. Case Report: We present the case of a male 75 year-old patient, with a...

Introduction: Macular edema is the main cause of visual loss in diabetic patients. In spite of the ample choice of therapeutic modalities, chronic macular edema management is a challenge to this date. Aside from laser and intravitreal therapies, the newest proposal by some authors has been vitrectomy with ILM peeling as a possible solution for many therapy-resistant cases, or even naive cases. Reducing traction, increasing retinal...

Epiretinal membranes are avascular, fibro-cellular membranes that proliferate on the surface of the retina. These membranes have contractile properties and patients may present with metamorphopsia and visual changes because of their effect on the underlying retina. Epiretinal membrane surgery usually implies pulling the ERM itself and commonly the internal limiting membrane, exerting forces on the retina that may easily damage and...

Purpose: To understand the postoperative evolution of BCVA and macular thickness with this technique and to conclude the benefits or not of it. Methods: Most of the surgeons use different dyes to visualize the posterior hyaloid, the ERM and the ILM and peel them in several steps. We decided to peel the ERM and the ILM only in one step using brilliant blue G or MEMBRANEBLUE-DUAL. We present the first 10 cases with this technique and their...

An intraocular foreign body (IOFB) must be excluded in all cases of eye perforation. An IOFB may traumatize the eye mechanically, introduce infection or cause other toxic effects (i.e.: siderosis) on the intraocular structures. Once in the eye, the foreign body may lodge in any of the structures (in the antherior chamber, in the angle, in the lens, in the vitreous or on the retina).Some of them are inert but an intraocular ferrous foreign...
