National Eye Institute (NEI)


The mission of the National Eye Institute is to eliminate vision loss and improve quality of life through vision research. To achieve this mission, NEI provides leadership to: 

  • Drive innovative research to understand the eye and visual system, prevent and treat vision diseases, and expand opportunities for people who are blind or have low vision 
  • Foster collaboration in vision research and clinical care to develop new ideas and share knowledge across other fields 
  • Recruit, inspire, and train a talented and diverse new generation of individuals to expand and strengthen the vision workforce 
  • Educate health care providers, scientists, policymakers, and the public about advances in vision research and their impact on health and quality of life

Vision research is supported by the NEI through research grants and training awards made to scientists at more than 250 medical centers, hospitals, universities, and other institutions across the country and around the world. The NEI also conducts laboratory and patient research on the NIH campus in Bethesda, Maryland.

The NEI has established the National Eye Health Education Program, a partnership of more than 65 professional, civic, and voluntary organizations and government agencies concerned with eye health. The program represents an extension of the NEI's support of vision research, where results are disseminated to health professionals, patients, and the public.

NEI Programs

Major Extramural Programs

NEI's extramural research activities are organized into six scientific areas: retinal diseases; corneal diseases; lens and cataract; glaucoma and optic neuropathies; strabismus, amblyopia, and visual processing; and low vision and blindness rehabilitation. In addition, the NEI supports research activities that cross-cut the major program areas. These cross-cutting areas of emphasis are ocular infection, inflammation, and immunology; small business innovative research; research training; oculomotor systems; ocular pain; collaborative clinical research; and myopia and refractive error.

Retinal Neuroscience and Retinal Diseases

NEI-supported investigations include studies of the development, molecular and cell biology, human genetics, and metabolism of the photoreceptor cells and their dependence on the underlying retinal pigment epithelium; the mechanism of the retina's response to light and the initial processing of information that is transmitted to the visual centers of the brain; and the pathogenesis, etiology, molecular biology and genetics, and treatment of retinal diseases such as diabetic retinopathy; uveitis; and retinitis pigmentosa, age-related macular degeneration, and retinal detachment.

Corneal Diseases

NEI-supported projects include studies of the regulation of genes that express proteins unique to corneal tissue; details of the assembly of corneal extracellular matrices; mechanisms that maintain corneal hydration and transparency; physiologic basis for immune privilege in the cornea; cell biology of corneal wound healing; corneal biomechanics; corneal infections; and the pathogenesis of corneal transplant rejection.

Lens and Cataract

NEI-supported research includes studies of normal lens development and aging; the molecular and cellular characterization of lens transparency; control of lens cell division; structure and regulation of the expression of lens-specific genes; the impact of environmental insults on the lens; and the pathogenesis of human cataract.

Glaucoma and Optic Neuropathies

NEI supports a range of research designed to better understand the pathophysiology underlying glaucoma, the discovery of drugs and surgical techniques for its treatment, the basis of racial and ethnic disparities in the incidence and severity of the disease, and the development of procedures for earlier diagnosis. Studies include the molecular genetics of glaucoma syndromes; physiologic mechanisms regulating fluid flow in the disease; the cell and molecular biology of optic nerve damage; ganglion cell death; mechanisms of neuroprotection as a possible treatment strategy, and genome-wide scans to detect disease risk factors.

Strabismus, Amblyopia, and Visual Processing

NEI supports studies concerned with the function of the neural pathways from the eye to the brain, the central processing of visual information, visual perception, the optical properties of the eye, the function of the pupil, and molecular cell biology of the extraocular muscles. Support is provided for research on the pathogenesis and treatment of eye movement disorders, and the development of myopia. Particular emphasis is placed on studies of strabismus and amblyopia, as these are frequent causes of lifelong visual impairment.

Low Vision and Blindness Rehabilitation

NEI supports research in low vision and rehabilitation of people with visual impairments and blindness. Examples include projects aimed at improving the methods of specifying, measuring, and categorizing loss of visual function; devising strategies to help visually impaired people maximize the use of their residual vision; systematically evaluating new and existing visual aids; and studying the optical, electronic, and other rehabilitative needs of people with visual impairments.

Ocular Infection, Inflammation, and Immunology

The study of immunologic, inflammatory, and infectious processes that underlie disease pathogenesis and susceptibility is common to all scientific programs of the NEI. Therefore, projects that focus on research in these areas have been organized into an overarching grant portfolio.

Myopia and Refractive Error

This cross-cutting scientific program supports studies to delineate the etiology of myopia, identify the biochemical pathways associated with control of the growth of the eye, and determine risk factors associated with the development of myopia and other refractive errors.

Oculomotor Systems

This program supports studies to develop a better understanding of the neural control, biomechanical properties, and anatomical relationships of the tissues around the eye muscles and the roles they play in guiding eye movements, as well as to attain a clearer understanding of how signals for voluntary eye movements are processed within cortical circuits.

Ocular Pain

This program supports studies of the pathophysiology of ocular pain and the development of new approaches to its treatment.

Collaborative Clinical Research

NEI supports single-center and multicenter clinical trials and other epidemiologic and health services research. Collectively, these projects are directed toward furthering knowledge about the predictors for and natural history of visual system diseases and disorders and developing better prevention and management strategies for these conditions.

Small Business Innovative Research Program

NEI supports studies which assist the small business community in commercializing innovative technologies.

Research Training Program

The NEI supports didactic and research training for pre-baccalaureate, doctoral, and post-doctoral level scientists through both individual and institutional awards.

Division of Intramural Research

Office of the Scientific Director

The Office of the Scientific Director (OSD) supports basic and clinical research within the Division of Intramural Research (DIR) that is carried out by over 150 researchers (investigators, staff scientists and clinicians, and scientific support staff) in various research disciplines. The NEI intramural program also provides training for about 120 fellows and students. In addition, the OSD oversees several shared core facilities that provide intellectual and technical support in genetic engineering, histopathology, biological imaging, visual function, and flow cytometry.

Examples of research carried out in DIR include:

  • pilot clinical trials
  • CNS reward circuits that control behavior
  • structure and function of genes and proteins with key roles in normal, aging and diseased eye
  • genetically engineered models for human eye disease
  • nerve cell communications that transmit visual information across the retina
  • biochemistry of the visual cycle
  • genetic susceptibility for AMD and diabetic retinopathy
  • genetic defects and pathways of retinal degeneration
  • genetic epidemiology
  • genetic origins of inherited ophthalmic diseases
  • childhood blinding diseases and inheritance
  • neuronal glial Interactions in retinal disease
  • animal models of inflammatory disease
  • inflammatory mechanisms in eye disease
  • physiology of the RPE and iPS cell-derived retinal pigment epithelia
  • protection of retinal neurons against elevated intraocular pressure in glaucoma
  • lipid oxidation in the retina and the RPE
  • gene therapeutics to treat X-linked retinoschisis, retinitis pigmentosa, and macular degeneration

Laboratory of Immunology

The goal of the Laboratory of Immunology is to perform cutting-edge, quality research in immunology and infectious diseases that is designed to help scientists better understand the normal physiologic state and the processes that perturb it, with special emphasis on inflammatory mechanisms in the eye as a model system. In pursuit of this goal the laboratory capitalizes on the unique research environment at NIH and the constant interaction between clinician and basic researcher.

Laboratory of Retinal Cell and Molecular Biology

The Laboratory of Retinal Cell and Molecular Biology plans, conducts, and directs basic research in normal and abnormal functioning of the retina, other ocular tissues, and in retinal diseases, particularly those of a genetic nature. Biochemical and molecular understanding of complex ocular pathologies, such as in age-related macular degeneration and glaucoma, is a major focus as is the discovery and application of possible therapies. Mechanisms of visual processes are emphasized as well as elucidating the complex functions of neuronal, glial, and pigment epithelial cells.

Laboratory of Sensorimotor Research

The goal of the Laboratory of Sensorimotor Research (LSR) is to understand the fundamental brain mechanisms that allow sensory-motor coordination. The laboratory concentrates on the system within the brain that is probably best understood in the control of the complex activities of the visual/oculomotor system. LSR's center of interest is how this system works in humans, both normally and when it fails as a result of disease or trauma. The ability to guide movements under sensory control is one of the most critical of human abilities. The use of this ability ranges from the mundane coordination needed in everyday life to the precision of the athletic achievement. Disorders of this ability are devastating and cost billions of dollars in custodial health care.

Neurobiology Neurodegeneration and Repair Laboratory

The goal of the Neurobiology Neurodegeneration and Repair Laboratory is to develop novel treatment modalities for blinding retinal diseases based on the fundamental understanding of genetic defects and/or biological pathways underlying differentiation, homeostasis, aging, and disease pathogenesis.

Ophthalmic Genetics and Visual Function Branch

The Ophthalmic Genetics and Visual Function Branch aims to understand developmental, genetic, molecular, and cellular aspects of ocular biology in health and disease and to enable, broaden, and strengthen basic and translational science throughout NEI. An overarching goal is to identify the underlying genes, genetic networks, and drug targets in disease and to utilize this knowledge to increase understanding of vision biology and the rational development of successful therapeutic interventions to slow or reverse disease progression. Over many years of clinical research, the Branch has compiled an impressive database of patients with fully characterized phenotypic information on a host of heritable ocular disorders. These disorders are amenable to further molecular genetic analysis and to future treatment protocols.

Office of the Clinical Director

The Office of the Clinical Director coordinates, supervises and supports intramural clinical research on the cause, diagnosis, prevention, and treatment of diseases of the visual system and fosters the translation of advances in laboratory research into clinical applications. The Office provides infrastructure needed to promote high quality clinical research and to ensure patient safety, including protocol review, clinical informatics, and data and safety management; (2) monitors quality assurance of the intramural clinical research program; (3) coordinates the credentialing of health care providers within the Institute; (4) administers the ophthalmology consultation service to provide eye care for patients referred from other Institutes; and; (5) coordinates and provides clinical research training for NIH staff, fellows, and students.

Division of Epidemiology and Clinical Applications

The Division of Epidemiology and Clinical Applications has three main functions: research, education, and consultation. Research is the dominant function. It is the Division’s mission to plan, develop, and conduct human population studies concerned with the cause, prevention, and treatment of eye disease and vision disorders, with emphasis on the major causes of blindness. This includes studies of incidence and prevalence in defined populations, prospective and retrospective studies of risk factors, natural history studies, clinical trials, genetic studies, and studies to evaluate diagnostic procedures. The Division carries out a program of education in biometric and epidemiologic principles and methods for the vision research community. This program consists of courses, workshops, a fellowship program for ophthalmologists, publications, and consultation and collaboration on research. Finally, the Division provides biometric and epidemiologic assistance to NEI intramural and extramural staff and to vision research workers elsewhere. The assistance ranges from consultation to collaboration as co-investigators. It continues to provide scientific support to investigators at the NIH Clinical Center as well as extramurally.
