Dr. Abhishek R. Kothari completed his undergraduation from Coimbatore Medical College and ophthalmology residency from S.M.S. Medical College, Jaipur. He completed a fellowship in vitreoretinal surgery at Sankara Nethralaya, Chennai and worked at the world renowned Aravind Eye Care System in India before moving to his current position. He has considerable experience as a practicing vitreoretinal surgeon. He is an active participant in specialty meetings and has presented several research papers. He has won prestigious awards for the same at national and international fora (including the All India Ophthalmologic Society Academic Research Committee Award 2007, S Natarajan All India Ophthalmologic Society award for best paper in Retina in 2009, the International College of Ophthalmology Merit Award 2009, the Best paper in the All India Ophthalmologic Society Retina 2010, The Natarajapillai Award 2010, Asia Pacific Vitreoretinal Society Merit award 2010, the Rajasthan Ophthalmic Premier League Award 2012 and many others). He has also delivered numerous presentations and instruction courses in various national and international conferences. He has published several papers and is the chief editor of a textbook on vitreoretinal surgery (Principles and Practice of Vitreoretinal Surgery, Jaypee Brothers, New Delhi), besides having authored several chapters in other textbooks. He is actively working on automated image recognition in OCT images using artificial intelligence /deep learning techniques, and has interests in the economization of high quality healthcare. He has trained several Indian and overseas vitreoretinal fellows. He has been invited and continues to teach medical and engineering postgraduates and doctoral students at several institutes.

    Perfluorocarbons in Ophthalmology

    INTRODUCTION Perfluorocarbon liquids (PFCLs) were first developed in 1970s as possible substitutes to erythrocytes[1],[2] because of their capacity to dissolve relatively large amounts of oxygen. Initial trials with these compounds focused on their feasibility to be used as blood substitutes. These experiments proved the biocompatibility of these compounds. Based on their properties, they were then introduced for intraocular use, in what has become a milestone in vitreoretinal surgery. After animal studies confirmed the safety of PFCL compounds as vitreous substitutes, Chang et al in 1987 first described the successful intraocular use of low viscosity liquid fluorocarbons (perfluorotributylamine and perfluorodecalin) in four patients with complicated retinal detachments.[3],[4] Long-term tamponade in animal models demonstrated retinal atrophy and retinal necrosis at the perfluorocarbon aqueous interface after 4 weeks even when highly purified PFCL compounds (perfluorodecalin) were used

    Optical Coherence Tomography- Evolution and Clinical Applications

    1. Introduction Optical coherence tomography (OCT) is a noninvasive imaging modality that has revolutionized the practice of clinical ophthalmology over the past decade. OCT provides high-resolution cross-sectional images of the retina, optic nerve head and retinal nerve fibre layer (RNFL) unobtainable by any other current modality, and enables qualitative and quantitative evaluation. As opposed to other retinal imaging modalities that provide én face images, it provides for sectional information, and in that sense is analogous to an in vivo “optical biopsy” (Figure 1). It is safe, fast, reproducible, does not require greatly skilled technicians, and has minimal, if any, interobserver issues. Several advances in recent times have contributed to vast improvements in resolution and speed of OCT devices, and expanded their applications manifold. In 2010, in the US alone, an estimated 16 million OCT procedures were done, amounting to $ 780 million in reimbursement.[1] Fig 1. Macular OCT wi
