Oftalmologi

This book describes the optical structure and optical properties of the human eye. It is divided into a number of short chapters with each chapter dedicated to a single theme. For ease of reference, the most commonly useful topics are at the beginning and topics with narrower appeal, such as ocular aberrations, are placed towards the end.

Nanotechnology in Ophthalmology is a comprehensive and up-to-date reference on the role and applications of nanotechnology in ophthalmology, from drug delivery and treatment of ocular diseases to toxicity issues. Written by experts from the nanotechnology, ophthalmology, and pharmacology fields, this book has a unique, broad and diverse scope, including chapters on nanosensor-based diagnostic tools, delivery of nanobiomaterials, implantable materials and devices, delivery of nanobiomaterials, nanotechnology for medical and surgical treatment, regenerative medicine, and more. This book provides a valuable reference to researchers working in the areas of ophthalmology, nanoscience and pharmacology, and clinical fellows who are interested in nanoophthalmology as a reference for their practice and research.

Microbiome and the Eye: What's the connection? highlights how alterations in the gut and eye microbiomes can lead to systemic immune alterations with subsequent effects on the eye. The book is divided into two sections, one highlighting how alterations in the gut microbiome impact various components of health outside the gut, with a focus on the immune system and inflammatory mediators, and the second focusing on studies on a variety of ocular diseases, including ocular surface diseases/dry eye, keratitis, uveitis, glaucoma, and retinopathy to gut dysbiosis. With its translational approach, the book is suitable for both researchers and clinicians. The book will help readers understand the mechanisms in which gut and eye microbiome composition may influence health in multiple compartments, with a focus on eye diseases.

This comprehensive revision guide is a key resource for, meeting the challenges of the FRCOphth Part 1 examination. Carefully mapped to the curriculum and reviewed by twelve leading experts in the field, it is the perfect revision aid for the FRCOphth Part 1.

This book provides a wide-ranging overview of artificial intelligence (AI), machine learning (ML) and deep learning (DL) algorithms in ophthalmology. Expertly written chapters examine AI in age-related macular degeneration, glaucoma, retinopathy of prematurity and diabetic retinopathy screening. AI perspectives, systems and limitations are all carefully assessed throughout the book as well as the technical aspects of DL systems for retinal diseases including the application of Google DeepMind, the Singapore algorithm, and the Johns Hopkins algorithm. Artificial Intelligence in Ophthalmology meets the need for a resource that reviews the benefits and pitfalls of AI, ML and DL in ophthalmology. Ophthalmologists, optometrists, eye-care workers, neurologists, cardiologists, internal medicine specialists, AI engineers and IT specialists with an interest in how AI can help with early diagnosis and monitoring treatment in ophthalmic patients will find this book to be an indispensable guide to an evolving area of healthcare technology.

Born blind. Minimal sight developed over her first years. Never told she had limited vision by parents or school, Pat Vint thought she was clumsy and stupid. At sixteen, she dreamed of the freedom of buying and driving a car. Her parents told her she would never see well enough to drive. This was the first time she learned it was her sight and only her sight that was holding her back.She began a fifty-two year journey Into Sight. First, good enough to drive - accomplished at thirty eight. Then, to conquer Nystagmus, a shaking of the eyes that made focus difficult. Finally, with the aid of prisms added to her lens, experiencing the world in three dimensions. Pat Vint become a child and family therapist and never stopped trying to improve her sight. When she discovered Vision Therapy and underwent a process called Multi Sensory Therapy or MST, she took a huge step forward. But along with clearer sight came mental hurdles to overcome. Realizing what she had been missing all those years. Redefining herself. This memoir, written as a series of diary entries captures the reader''s imagination. Each one of us has some defining "handicap". How many of us have given in, given up, thinking "that''s just how it''s going to be"? Pat never gave up. And through her journey, we can experience the exhilleration as well as the challenges and fears of overcoming those roadblocks and getting what you''ve always wished for.This journey Into Sight shows us all the wonders available for each of us if we only keep trying. Growth is sometimes frightening, sometimes exciting, but always inspiring and always waiting for us.
