Ophthalmology is a clinical and surgical specialty within medicine that deals with the diagnosis and treatment of eye disorders. A former term is oculism.
Retinopathy is any damage to the retina of the eyes, which may cause vision impairment. Retinopathy often refers to retinal vascular disease, or damage to the retina caused by abnormal blood flow. Age-related macular degeneration is technically included under the umbrella term retinopathy but is often discussed as a separate entity. Retinopathy, or retinal vascular disease, can be broadly categorized into proliferative and non-proliferative types. Frequently, retinopathy is an ocular manifestation of systemic disease as seen in diabetes or hypertension. Diabetes is the most common cause of retinopathy in the U.S. as of 2008. Diabetic retinopathy is the leading cause of blindness in working-aged people. It accounts for about 5% of blindness worldwide and is designated a priority eye disease by the World Health Organization.
The National Eye Institute (NEI) is part of the U.S. National Institutes of Health (NIH), an agency of the U.S. Department of Health and Human Services. The mission of NEI is "to eliminate vision loss and improve quality of life through vision research." NEI consists of two major branches for research: an extramural branch that funds studies outside NIH and an intramural branch that funds research on the NIH campus in Bethesda, Maryland. Most of the NEI budget funds extramural research.

The visual field is "that portion of space in which objects are visible at the same moment during steady fixation of the gaze in one direction"; in ophthalmology and neurology the emphasis is on the structure inside the visual field and it is then considered “the field of functional capacity obtained and recorded by means of perimetry”.
Visual or vision impairment is the partial or total inability of visual perception. In the absence of treatment such as corrective eyewear, assistive devices, and medical treatment – visual impairment may cause the individual difficulties with normal daily tasks including reading and walking. The terms low vision and blindness are often used for levels of impairment which are difficult or impossible to correct and significantly impact daily life. In addition to the various permanent conditions, fleeting temporary vision impairment, amaurosis fugax, may occur, and may indicate serious medical problems.
An eye care professional is an individual who provides a service related to the eyes or vision. It is any healthcare worker involved in eye care, from one with a small amount of post-secondary training to practitioners with a doctoral level of education.
Ranibizumab, sold under the brand name Lucentis among others, is a monoclonal antibody fragment (Fab) created from the same parent mouse antibody as bevacizumab. It is an anti-angiogenic that is approved to treat the "wet" type of age-related macular degeneration, diabetic retinopathy, and macular edema due to branch retinal vein occlusion or central retinal vein occlusion.
The Donald K. Johnson Eye Centre is Canada's largest clinical and research institute for vision. It is located in Toronto at the Toronto Western Hospital.
Blurred vision is an ocular symptom where vision becomes less precise and there is added difficulty to resolve fine details.
Macular telangiectasia is a condition of the retina, the light-sensing tissue at the back of the eye that causes gradual deterioration of central vision, interfering with tasks such as reading and driving.
The John A. Moran Eye Center at the University of Utah is an ophthalmology clinical care and research facility in the Mountain West.
Laser coagulation or laser photocoagulation surgery is used to treat a number of eye diseases and has become widely used in recent decades. During the procedure, a laser is used to finely cauterize ocular blood vessels to attempt to bring about various therapeutic benefits.
Bascom Palmer Eye Institute is the University of Miami School of Medicine's ophthalmic care, research, and education center. The institute is based in the Health District of Miami, Florida, and has been ranked consistently as the best eye hospital and vision research center in the nation.
The Universitäts-Augenklinik Düsseldorf is the department of Ophthalmology of the University Hospital of Düsseldorf in Germany. It is an internationally renown centre for corneal transplantation, ocular surface disease and management of associated disorders ranging from Glaucoma to oculoplastic surgery. Further subspecialist expertise is established for the diagnosis and surgical and medical treatment of vitreoretinal and macular disorders as well as strabismus.
Joan Whitten Miller is a Canadian-American ophthalmologist and scientist who has made notable contributions to the treatment and understanding of eye disorders. She is credited for developing photodynamic therapy (PDT) with verteporfin (Visudyne), the first pharmacologic therapy for retinal disease. She also co-discovered the role of vascular endothelial growth factor (VEGF) in eye disease and demonstrated the therapeutic potential of VEGF inhibitors, forming the scientific basis of anti-VEGF therapy for age-related macular degeneration (AMD), diabetic retinopathy, and related conditions.
Paul A. Sieving is a former director of the National Eye Institute, part of the U.S. National Institutes of Health. Prior to joining the NIH in 2001, he served on the faculty of the University of Michigan Medical School as the Paul R. Lichter Professor of Ophthalmic Genetics. He also was the founding director of the Center for Retinal and Macular Degeneration in the university's Department of Ophthalmology and Visual Sciences.
Peter Szurman is a German ophthalmologist, scientist, and professor of ophthalmology in Sulzbach/Saar.
Adrienne Williams Scott is an American ophthalmologist specialized in diabetic retinopathy, epiretinal membranes, and macular degeneration. She is chief of the Wilmer Eye Institute in Bel Air, Harford County, Maryland. She is an associate professor of ophthalmology at Johns Hopkins School of Medicine.
Drug abuse retinopathy is damage to the retina of the eyes caused by chronic drug abuse. Types of retinopathy caused by drug abuse include maculopathy, Saturday night retinopathy, and talc retinopathy. Common symptoms include temporary and permanent vision loss, blurred vision, and night blindness. Substances commonly associated with this condition include poppers, heroin, cocaine, methamphetamine, tobacco, and alcohol.
