Ocular infections remain an important cause of ocular morbidity and loss of vision, yet many are preventable or curable. Early diagnosis and prompt treatment help in the control of such infectious disorders and the prevention of blindness. There are many infectious diseases of the eye and adnexa and knowledge of their diagnosis and management is essential to an optimal therapeutic outcome. This book provides the practitioner with the important information required to ensure appropriate diagnosis and management of ocular infectious diseases. Specific clinical signs and symptoms are outlined, and the role of specific diagnostic tests, including molecular biology techniques, is explained. All of the most common microorganisms are considered and current knowledge on the antimicrobial therapy of ocular infections is clearly summarized. Ocular Infections will be a great help to physicians as a guide to the care of patients with ocular infectious diseases.

Since ocular infections are one of the most frequent occurrences in ophthalmology, the treatment for these infections must be fast, precise and effective. In order to address this goal, it is important to identify and characterize the culprit microorganisms involved in the pathogenesis of ocular infections. Clinical diagnosis of ocular infections can be confirmed by several techniques based on microbiological test of ocular samples. Some of these techniques include classic microbiological testing in which it is necessary to isolate microorganisms to characterize them by biochemical analysis which require significant resources and timing.

This book is a new addition for a broad-spectrum library in ophthalmology and other specialties in medicine of "InTech." It addresses ocular infections. These infections may result in blindness if not correctly diagnosed and promptly treated. Therefore, it is essential to be fully aware and knowledgeable about the manifestations of these diseases, and this book covers some of the different aspects of them. The chapters were written by experts from around the globe and these reflect the importance of the subject. The book is aimed for ophthalmologists, residents in ophthalmology and infectious diseases, general practitioners, and researchers in hope to advance the knowledge for the benefit of the world habitants wherever they are.

The human eye and its associated structures are susceptible to several diseases and disorders, and age-related changes. Eye infections, such as conjunctivitis are characterized by inflammation, pain, scratchiness, burning and itchiness. It is a fairly common infection occurring in children, people wearing contact lenses and people infected with chlamydia or gonorrhea. It is primarily caused by a viral or bacterial infection. Keratitis is another infection of the eye in which the cornea of the eye becomes inflamed. It is characterized by photophobia, impaired eyesight, red eye and pain. It can be acute or chronic. Such infections can be caused due to bacterial, fungal, viral and parasitic agents. Endophthalmitis is another eye infection in which the interior of the eye gets inflamed. It can potentially lead to a loss of vision and the eye itself. Although it is triggered by a viral or fungal infection, it can occur due to a penetrating trauma, intravitreal injections and retained intraocular foreign bodies. Antibiotic and steroid eye drops are used to treat eye infections or to prevent them from occurring after eye surgeries. The branch of medicine and surgery that is concerned with the diagnosis and treatment of eye infections is known as ophthalmology. Some of the diverse topics covered in this book address the various infections of the eye. The various advancements in ophthalmology, in relation to eye infection diagnosis and management, are glanced at and their applications as well as ramifications are looked at in detail. It will provide comprehensive knowledge to the readers.

This book is a concise guide to the prevention and management of post-surgical ocular infections covering both common and serious conditions. Divided into 24 chapters, the text begins with discussion on preventive aspects including an introduction to the operating theatre, air flow and water requirements, and patient and personnel preparation. The following sections describe the diagnosis, treatment and prevention of infections resulting from different ocular surgeries. This practical guide is highly illustrated with clinical photographs and flow charts highlighting significant aspects of prevention and management. Key points Concise guide to prevention and management of post-surgical ocular infections Covers both common and serious conditions resulting from different types of surgery Explains basic preventive measures relating to the operating theatre and personnel Highly illustrated with clinical photographs and flow charts

Bacterial eye infections are among the leading causes of vision loss and ocular morbidity, yet the widespread use of antibiotics, particularly in combating systemic infections, has led to increased resistance. This book describes studies that have reported resistance to fourth-generation fluoroquinolones used for treating ocular infections. Achieving optimal therapeutic outcomes, which will require new antimicrobial agents with less potential for promoting resistance is also discussed. This book explores endophthalmitis as an intraocular inflammation mainly involving the ocular fluids. Pseudomonas aeruginosa is also reviewed, which is a major opportunistic pathogen and a common cause of bacterial keratitis, especially in contact lens wearers. The new classes of antibiotics have offered alternatives to treat this otherwise antibiotic-resistant bacteria but reports of continued resistance indicate the need for novel areas such as the use of immunisations with attenuated strains of bacteria and treatment with non-antibiotic compounds. Myopia is the most common eyesight problem in the world and is often mild and there are no serious problems. However, it may sometimes lead to blindness. This book explores laser as a way to correct myopia as well as a study of myopia.Finally, this book includes two approaches to resolve myopic macular retinoschisis; one is an approach from inside the eye and the other is from outside the eye. An investigation of eyes for corneal, refractional, and biometric changes, which resulted in the conclusion that there is a statistically significant myopic shift after scleral buckling surgery, is evaluated.
