Intra-operative optical coherence tomography (OCT) requires a display technology which allows surgeons to visualize OCT data without disrupting surgery. Previous research and commercial intrasurgical OCT systems have integrated heads-up display (HUD) systems into surgical microscopes to provide monoscopic viewing of OCT data through one microscope ocular. To take full advantage of our previously reported real-time volumetric microscope-integrated OCT (4D MIOCT) system, we describe a stereoscopic HUD which projects a stereo pair of OCT volume renderings into both oculars simultaneously...

Over the past four decades, advancements in surgical instrumentations and techniques have significantly improved the postoperative anatomical and visual outcomes of patients with various diabetic vitreoretinal diseases. In particular, surgical interventions for previously serious and untreatable blinding proliferative diabetic retinopathy can now be performed, with much better results. The advents of micro incisional vitrectomy system with better visualization system like binocular indirect ophthalmomicroscope and state-of-the-art instrumentation revolutionized the era of diabetic vitrectomy...

The number of people with diabetic retinopathy (DR) has increased with the increasing prevalence of diabetes mellitus worldwide, especially in developing countries. In recent years, the successful implementation of public health programs in developed countries has been thought to contribute to decreases in blindness from DR. Developing countries, however, have not seen the same improvements, and their public health interventions still face significant challenges. In this review we describe the current state of public health approaches including risk factor control, screening and treatment techniques for DR in developing countries, and suggest recommendations...

Vitreous substitutes are crucial adjuncts during vitreo-retinal surgery for retinal diseases such as complicated retinal detachment, macular holes, complications of diabetic retinopathy, and ocular trauma involving posterior segment. In retinal detachment surgery, an internal tamponade agent is required to provide internal pressure for reattachment of the detached neurosensory retina. Current available options serve only as a temporary surgical adduct or short-term solution and are associated with inherent problems...

The number of elderly patients using anticoagulant and antiplatelet treatment in prevention of thromboembolism has significantly increased in recent years. It was believed for many years that those patients may be at higher risk for hemorhages during ocular surgery. Different strategies were proposed to prevent these complications, including discontinuation of anticoagulants, dose reduction, or substitution with low molecular weight heparin. The objective of this work was to evaluate the results of studies presenting the results of vitreoretinal surgeries in patients continuing antiplatelet and/or anticoagulant treatment...

Matin Khoshnevis, J Sebag
With increased knowledge about the origins and pathophysiology of vitreo-retinal disorders—and, in particular, the central role of anomalous posterior vitreous detachment in vitreo-maculopathies—a paradigm shift from surgery to pharmacotherapy is taking place with the development of pharmacologic vitreolysis. The first approved agent for pharmacologic vitreolysis therapy is ocriplasmin, a truncated form of the nonspecific serine protease plasmin. Twelve studies comprise the current ocriplasmin clinical trial program, demonstrating the efficacy and safety of a single intravitreal injection of ocriplasmin for the treatment of patients with symptomatic vitreo-macular adhesion or vitreo-macular traction, including patients with macular holes...

Epiretinal membrane is avascular fibrous tissue which is adhered to the internal layers of retina in the macular area. Patient may be asymptomatic or present with blurring of vision and metamorphopsia. The idiopathic Epiretinal Membrane is more often seen in elderly but it could be present in young patients in association with other vitreo-retinal diseases and following intraocular surgery. The idiopathic Eperetinal Membrane in young patients are rare. Here we present a thirty one year healthy women presented with idiopathic Epiretinal Membrane who gained full visual recovery following the pars plana vitrectomy, membrane peeling and gas for its rarity...
