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.
