The retina is the light-sensitive innermost layer of tissue in the eyes of vertebrates and certain molluscs. Retinal diseases are the medical conditions affecting any part of the retina. There are many different retinal diseases and the majority of them cause visual symptoms. These may include a muted color vision, noticing flashes of light, straight lines that appear wavy, difficulty seeing in low light, etc. Some retinal conditions are more common as people develop diabetes or get older. Risk factors for these diseases can be genetic or hereditary, like retinitis pigmentosa. Fundus autofluorescence (FAF), MRI and CT, indocyanine green angiography, Amsler grid test, fluorescein angiography, ultrasound and other tests can be used to identify the location and severity of retinal diseases. The use of dietary supplements, intravitreal medicine like corticosteroid or anti-VEGF agents, and vitreoretinal surgery are some of the main modes of treatment for these diseases. This book contains some path-breaking studies on retinal diseases. It is appropriate for students seeking detailed information on these diseases as well as for experts.

The retina is a thin layer of neural tissue that lines the inside of the eye and records visual stimuli. Retinal diseases are various conditions that affect the retina and leads to vision issues. Various retinal problems can result from physiological, environmental or hereditary factors which might result in blindness. Majority of retinal problems can be delayed or prevented if they are detected early. The objective of treatment is to protect and restore eyesight, or to lessen and stop retinal deterioration. Treatment for retinal diseases differs according to the severity and type of condition. Treatment options can include everything from prescription drugs and vitamins to laser therapy, injections and surgery. Various developments in the knowledge, diagnosis and treatment of retinal diseases have become possible by the application of molecular genetic techniques. This book explores all the important aspects of retinal diseases in the present day scenario. It aims to understand the clinical perspectives of these diseases. This book is appropriate for students seeking detailed information in this area of study as well as for experts.

Retinal diseases are those diseases that affect the light-sensitive tissue found in the back side of the eye. There are various common retinal diseases and conditions, such as macular hole, retinal tear, epiretinal membrane, retinitis pigmentosa, retinal detachment, macular degeneration and diabetic retinopathy. Several retinal diseases have some symptoms in common, which include distorted or blurred vision, lost vision, seeing floating specks or cobwebs, and defects in side vision. There are various risk factors of retinal diseases, which include having diabetes, or other diseases, aging, having a family history of retinal diseases, smoking, eye trauma, and obesity. Optical coherence tomography, wide-field retinal imaging and dilated retinal examination are a few of the tests used to diagnose retinal disease. The treatment of retinal disease can be complicated at times and can include various treatment options, such as implanting a retinal prosthesis, shrinking abnormal blood vessels, injecting gas or air into the eye, evacuating and replacing the fluid in the eye, using a laser surgery, or freezing. This book unravels the recent studies on retinal diseases. Those in search of information to further their knowledge will be greatly assisted by this book.
