Internal Limiting Membrane Peeling in Macular Disorders

ABSTRACT The internal limiting membrane (ILM) is a thin, transparent, acellular membrane that forms the innermost boundary of the retina. ILM is the basal lamina of the inner retina, it is formed by the footplates of Müller cells and is composed of collagen fibers, glycosaminoglycans, laminin, and fibronectin. It has an important role in the early stages of retinal and optic nerve development, as a critical component of retinal...

Suprachoroidal Hemorrhages – Review and Clinical Cases

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...

Combined Artificial Iris-IOL Implantation in Traumatic Aphakia-Aniridia

EDITED FILM ABSTRACT Iris defects combined with crystalline lens abnormalities are among the major complications of globe blunt trauma. Post-traumatic partial or total iris defects can cause glare, reduced contrast sensitivity, decreased vision, photophobia as well as cosmetic problems. When there is extensive iris damage repair may be impossible and artificial iris implants can be used to restore iris diaphragm, reducing aniridia...

My Way to Perform the Inverted Flap Technique for MH

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...

Entry-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...

A Retinal Detachment with Panuveitis and MH

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...

Chronic Diffuse DME: The Role of Vitrectomy vs Intravitreal Therapy

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...

ERM and ILM Removal in One Step – Functional and Morphologic Results

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...

A Piece of Steel Removed by 23 Gauge Vitrectomy

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...
