ERM surgery is a demanding state-of-the-art procedure, consisting of ERM, and usually internal limiting membrane (ILM) removal. The use of multiple dyes, or the...

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...

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: Retinal detachments with giant retinal tears pose a significant challenge, even to the most experienced vitreoretinal specialists.

Methods: We present our adopted...

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...

Introduction: Vitreous hemorrhages during vitrectomy are not an uncommon event, particularly in diabetic patients. However, intraoperative vitreous hemorrhages resulting from conjunctival and/or episcleral hemorrhages, after the successful closure of 23G scleral ports, is a rare finding, never before experienced by our surgical team. The authors present the case of a young man undergoing vitrectomy for persistent vitreous haze, that had a...

Introduction: Ocriplasmin is a truncated plasmin derivative, with vitreolytic enzymatic activity. Following the MIVI-TRUST study, it was approved as a therapeutic option for focal (<1500μm) VMT (Vitreomacular Traction), when accompanied by visual symptoms and/or a macular hole < 400μm. Although few complications have been reported, a few authors report on the unpredictability of the results of this treatment. The authors...

Introduction: Intravitreal dexamethasone implants are currently an opti on for chronic macular edema due to diabetes, non-infectious uveitis and retinal vein occlusion. Anterior chamber migration is a rare event, occurring mostly in vitrectomized patients without posterior capsule integrity. This condition is associated with persistent corneal edema and ocular hypertension, therefore requiring intervention. The few cases published suggest...

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...

http://www.dailymotion.com/video/x16sglm Objective: Description of 8 idiopathic macular holes that had an unusual evolution. Introduction: Macular hole is the absence of macular retinal layers. Most idiopathic macular holes have a good outcome after surgery, which is vitrectomy, ILM peeling and gas tamponade. However, some unusual cases are still challenging the actual management of this pathology. Cases: (1) Surgical closure of macular...

http://www.dailymotion.com/video/x15zr06 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...

Introduction: Phakic refractive lenses may get dislocated into the vitreous cavity and retina. When placed on both eyes, it may occur in only one of them, causing anisometropy. Subject and methodology: The patient was a 46 year old female who had undergone refractive surgery for high myopia in 2002. Two Phakic Refractive Lenses were introduced. In June 2012 the patient was sent to our Retinal Surgery Department, at the Ophthalmology Service...

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...

Surgery is the common therapy for  idiopathic epiretinal membranes when the visual acuity is changed and the macular thickness is increasing disturbing the vision quality. The procedure usually follows some steps: (23 gauge; 25 gauge; 27 gauge) Pars Plana Vitrectomy, posterior hyaloid detachment, ERM peeling and ILM peeling with the use of different dyes. Many Surgeons use triamcinolone for the vitrectomy and for the posterior hyaloid...
