Blindness
The inability to see or the loss or absence of perception of visual stimuli. This condition may be the result of EYE DISEASES; OPTIC NERVE DISEASES; OPTIC CHIASM diseases; or BRAIN DISEASES affecting the VISUAL PATHWAYS or OCCIPITAL LOBE.
Night Blindness
Failure or imperfection of vision at night or in dim light, with good vision only on bright days. (Dorland, 27th ed)
Blindness, Cortical
Total loss of vision in all or part of the visual field due to bilateral OCCIPITAL LOBE (i.e., VISUAL CORTEX) damage or dysfunction. Anton syndrome is characterized by the psychic denial of true, organic cortical blindness. (Adams et al., Principles of Neurology, 6th ed, p460)
Vision, Low
Vision considered to be inferior to normal vision as represented by accepted standards of acuity, field of vision, or motility. Low vision generally refers to visual disorders that are caused by diseases that cannot be corrected by refraction (e.g., MACULAR DEGENERATION; RETINITIS PIGMENTOSA; DIABETIC RETINOPATHY, etc.).
Onchocerciasis, Ocular
Filarial infection of the eyes transmitted from person to person by bites of Onchocerca volvulus-infected black flies. The microfilariae of Onchocerca are thus deposited beneath the skin. They migrate through various tissues including the eye. Those persons infected have impaired vision and up to 20% are blind. The incidence of eye lesions has been reported to be as high as 30% in Central America and parts of Africa.
Cataract
Partial or complete opacity on or in the lens or capsule of one or both eyes, impairing vision or causing blindness. The many kinds of cataract are classified by their morphology (size, shape, location) or etiology (cause and time of occurrence). (Dorland, 27th ed)
Visually Impaired Persons
Persons with loss of vision such that there is an impact on activities of daily living.
Xerophthalmia
Dryness of the eye surfaces caused by deficiency of tears or conjunctival secretions. It may be associated with vitamin A deficiency, trauma, or any condition in which the eyelids do not close completely.

Transmission of gene defects or chromosomal aberrations/abnormalities which are expressed in extreme variation in the structure or function of the eye. These may be evident at birth, but may be manifested later with progression of the disorder.
Visual Acuity
Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast.
Eye Diseases
Diseases affecting the eye.

These may result from EYE DISEASES; OPTIC NERVE DISEASES; VISUAL PATHWAY diseases; OCCIPITAL LOBE diseases; OCULAR MOTILITY DISORDERS; and other conditions (From Newell, Ophthalmology: Principles and Concepts, 7th ed, p132).
Glaucoma
An ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. The consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches. (Dictionary of Visual Science, 4th ed)
Cataract Extraction
The removal of a cataractous CRYSTALLINE LENS from the eye.
Refractive Errors
Deviations from the average or standard indices of refraction of the eye through its dioptric or refractive apparatus.
Vitamin A Deficiency
A nutritional condition produced by a deficiency of VITAMIN A in the diet, characterized by NIGHT BLINDNESS and other ocular manifestations such as dryness of the conjunctiva and later of the cornea (XEROPHTHALMIA). Vitamin A deficiency is a very common problem worldwide, particularly in developing countries as a consequence of famine or shortages of vitamin A-rich foods. In the United States it is found among the urban poor, the elderly, alcoholics, and patients with malabsorption. (From Cecil Textbook of Medicine, 19th ed, p1179)

Color Vision Defects
Defects of color vision are mainly hereditary traits but can be secondary to acquired or developmental abnormalities in the CONES (RETINA). Severity of hereditary defects of color vision depends on the degree of mutation of the ROD OPSINS genes (on X CHROMOSOME and CHROMOSOME 3) that code the photopigments for red, green and blue.
Onchocerca volvulus
A species of parasitic nematodes widely distributed throughout central Africa and also found in northern South America, southern Mexico, and Guatemala. Its intermediate host and vector is the blackfly or buffalo gnat.
Optic Atrophy
Atrophy of the optic disk which may be congenital or acquired. This condition indicates a deficiency in the number of nerve fibers which arise in the RETINA and converge to form the OPTIC DISK; OPTIC NERVE; OPTIC CHIASM; and optic tracts. GLAUCOMA; ISCHEMIA; inflammation, a chronic elevation of intracranial pressure, toxins, optic nerve compression, and inherited conditions (see OPTIC ATROPHIES, HEREDITARY) are relatively common causes of this condition.
Retina
The ten-layered nervous tissue membrane of the eye. It is continuous with the OPTIC NERVE and receives images of external objects and transmits visual impulses to the brain. Its outer surface is in contact with the CHOROID and the inner surface with the VITREOUS BODY. The outer-most layer is pigmented, whereas the inner nine layers are transparent.

Leber Congenital Amaurosis
A rare degenerative inherited eye disease that appears at birth or in the first few months of life that results in a loss of vision. Not to be confused with LEBER HEREDITARY OPTIC NEUROPATHY, the disease is thought to be caused by abnormal development of PHOTORECEPTOR CELLS in the RETINA, or by the extremely premature degeneration of retinal cells.
Retinopathy of Prematurity
A bilateral retinopathy occurring in premature infants treated with excessively high concentrations of oxygen, characterized by vascular dilatation, proliferation, and tortuosity, edema, and retinal detachment, with ultimate conversion of the retina into a fibrous mass that can be seen as a dense retrolental membrane. Usually growth of the eye is arrested and may result in microophthalmia, and blindness may occur. (Dorland, 27th ed)

Vision Screening
Application of tests and examinations to identify visual defects or vision disorders occurring in specific populations, as in school children, the elderly, etc. It is differentiated from VISION TESTS, which are given to evaluate/measure individual visual performance not related to a specific population.
Myopia
A refractive error in which rays of light entering the EYE parallel to the optic axis are brought to a focus in front of the RETINA when accommodation (ACCOMMODATION, OCULAR) is relaxed. This results from an overly curved CORNEA or from the eyeball being too long from front to back. It is also called nearsightedness.
Uveitis

Oman
A sultanate on the southeast coast of the Arabian peninsula. Its capital is Masqat. Before the 16th century it was ruled by independent emirs but was captured and controlled by the Portuguese 1508-1648. In 1741 it was recovered by a descendent of Yemen's imam. After its decline in the 19th century, it became virtually a political and economic dependency within the British Government of India, retaining close ties with Great Britain by treaty from 1939 to 1970 when it achieved autonomy. The name was recorded by Pliny in the 1st century A.D. as Omana, said to be derived from the founder of the state, Oman ben Ibrahim al-Khalil. (From Webster's New Geographical Dictionary, 1988, p890; Oman Embassy, Washington; Room, Brewer's Dictionary of Names, 1992, p391)

Sensory perception: supernormal hearing in the blind? (1/1462)

A recent experimental study suggests that blind individuals may compensate for their lack of vision with better-than-normal hearing. This provides support for a view dating back to 18th century philosophers, but the data raise as many problems as they solve.  (+info)

Histologic analysis of photochemical lesions produced in rhesus retina by short-wave-length light. (2/1462)

The photopathology of retinal lesions produced by extended exposure (1000 sec) to low corneal power levels (62 microW) of blue light (441 nm) was investigated by light microscopy in 20 rhesus eyes over an interval ranging from 1 hr to 90 days after exposure. Results indicate a nonthermal type of photochemical lesion originating in the retinal pigment epithelium and leading to a histological response with hypopigmentation which requires 48 hr to appear. This type of lesion helps to explain solar retinitis and eclipse blindness and has significance for aging and degenerative changes in the retina.  (+info)

A new X linked neurodegenerative syndrome with mental retardation, blindness, convulsions, spasticity, mild hypomyelination, and early death maps to the pericentromeric region. (3/1462)

We report on a family with an X linked neurodegenerative disorder consisting of mental retardation, blindness, convulsions, spasticity, and early death. Neuropathological examination showed mild hypomyelination. By linkage analysis, the underlying genetic defect could be assigned to the pericentromeric region of the X chromosome with a maximum lod score of 3.30 at theta=0.0 for the DXS1204 locus with DXS337 and PGK1P1 as flanking markers.  (+info)

Changing trends in barriers to cataract surgery in India. (4/1462)

Cataract is a major cause of blindness in Asia. Efforts in India to provide cataract surgical services have had limited success in reaching the cataract-blind population. Earlier studies identified the major barriers to cataract surgery as poverty, lack of transportation or felt need, or sex related; and the critical barriers in rural areas as lack of awareness, difficult access, and cost. Compared with these earlier data, the results of the present study in Karnataka State indicate a shift in the character of the barriers. They now appear to be more related to case selection and service provision. These shifts are analysed and alternative strategies to increase the uptake to cataract surgery are recommended.  (+info)

Economic burden of blindness in India. (5/1462)

Economic analysis is one way to determine the allocation of scarce resources for health-care programs. The initial step in this process is to estimate in economic terms the burden of diseases and the benefit from interventions for prevention and treatment of these diseases. In this paper, the direct and indirect economic loss due to blindness in India is calculated on the basis of certain assumptions. The cost of treating cataract blindness in India is estimated at current prices. The economic burden of blindness in India for the year 1997 based on our assumptions is Rs. 159 billion (US$ 4.4 billion), and the cumulative loss over lifetime of the blind is Rs. 2,787 billion (US$ 77.4 billion). Childhood blindness accounts for 28.7% of this lifetime loss. The cost of treating all cases of cataract blindness in India is Rs. 5.3 billion (US$ 0.15 billion). Similar estimates for causes of blindness other than cataract have to be made in order to develop a comprehensive approach to deal with blindness in India.  (+info)

No effect of pinealectomy on the parallel shift in circadain rhythms of adrenocortical activity and food intake in blinded rats. (6/1462)

Twenty-four-hr patterns of plasma corticosterone levels were determined at 4-hr intervals every 3-4 weeks in sighted and blinded pinealectomized rats of adult age. Through the whole period of the experiment, 24-hr patterns of food intake were also measured weekly. The sighted rats manifested the same 24-hr patterns of plasma corticosterone levels and food intake for 15 weeks after pinealectomy as those observed in the intact control rats. The magnitude of peak levels of plasma corticosterone and the amount of food intake did not differ between the two groups. A phase shift in circadian rhythms of plasma corticosterone levels and food intake was observed in both groups of blinded rats, with and without pinealectomy. Between the two groups, the patterns of phase shift were essentially similar for 10 weeks examined after optic enucleation. The peak elevation of plasma levels took place at 11 p.m. at the end of the 4th week after optic enucleation. Thereafter, 4- to 8-hr delay of peak appearance was observed every 3 weeks. No significant differences were found in peak values between the two groups of blinded rats. Furthermore, the circadian rhythm of food intake shifted in parallel with that of plasma corticosterone levels. A phase reversal of these two activities was observed between the 8th and 10th week after the operation. These results indicate that the pineal gland does not play any important role either in the maintenance of normal circadian periodicities of adrenocortical activity and food intake or in the shift in circadian rhythms of the two activities in the blinded rats.  (+info)

Elementary visual hallucinations, blindness, and headache in idiopathic occipital epilepsy: differentiation from migraine. (7/1462)

This is a qualitative and chronological analysis of ictal and postictal symptoms, frequency of seizures, family history, response to treatment, and prognosis in nine patients with idiopathic occipital epilepsy and visual seizures. Ictal elementary visual hallucinations are stereotyped for each patient, usually lasting for seconds. They consist of mainly multiple, bright coloured, small circular spots, circles, or balls. Mostly, they appear in a temporal hemifield often moving contralaterally or in the centre where they may be flashing. They may multiply and increase in size in the course of the seizure and may progress to other non-visual occipital seizure symptoms and more rarely to extra-occipital manifestations and convulsions. Blindness occurs usually from the beginning and postictal headache, often indistinguishable from migraine, is common. It is concluded that elementary visual hallucinations in occipital seizures are entirely different from visual aura of migraine when individual elements of colour, shape, size, location, movement, speed of development, duration, and progress are synthesised together. Postictal headache does not show preference for those with a family history of migraine. Most of the patients are misdiagnosed as having migraine with aura, basilar migraine, acephalgic migraine, or migralepsy simply because physicians are not properly informed of differential diagnostic criteria. As a result, treatment may be delayed for years. Response to carbamazepine is excellent and seizures may remit.  (+info)

Developing a model to reduce blindness in India: The International Centre for Advancement of Rural Eye Care. (8/1462)

With the continuing high magnitude of blindness in India, fresh approaches are needed to effectively deal with this burden on society. The International Centre for Advancement of Rural Eye Care (ICARE) has been established at the L.V. Prasad Eye Institute in Hyderabad to develop such an approach. This paper describes how ICARE functions to meet its objective. The three major functions of ICARE are design and implementation of rural eye-care centres, human resource development for eye care, and community eye-health planning. ICARE works with existing eye-care centres, as well as those being planned, in underserved areas of India and other parts of the developing world. The approach being developed by ICARE, along with its partners, to reduce blindness is that of comprehensive eye care with due emphasis on preventive, curative and rehabilitative aspects. This approach involves the community in which blindness is sought to be reduced by understanding how the people perceive eye health and the barriers to eye care, thereby enabling development of strategies to prevent blindness. Emphasis is placed on providing good-quality eye care with attention to reasonable infrastructure and equipment, developing a resource of adequately trained eye-care professionals of all cadres, developing a professional environment satisfactory for patients as well as eye-care providers, and the concept of good management and financial self-sustainability. Community-based rehabilitation of those with incurable blindness is also part of this approach. ICARE plans to work intensively with its partners and develop these concepts further, thereby effectively bringing into practice the concept of comprehensive eye care for the community in underserved parts of India, and later in other parts of the developing world. In addition, ICARE is involved in assessing the current situation regarding the various aspects of blindness through well-designed epidemiologic studies, and projecting the eye-care needs for the future with the help of reliable information. With balanced attention to infrastructure, manpower, financial self-sustenance, and future planning, ICARE intends to develop a practical model to effectively reduce blindness in India on a long-term basis.  (+info)

The many challenges of childhood blindness | British Journal of OphthalmologyThe many challenges of childhood blindness | British Journal of Ophthalmology
There are an estimated 45 million blind people in the world of whom only 3% are children.1 This dramatic difference in numbers of blind adults compared with children accounts in part for the relatively minor importance that has been attributed to the problem surrounding childhood blindness. Certainly, the well organised advocacy groups for the elderly in many developed countries are not matched by comparable ones for children. The result of this can be seen in the difference in resources made available for health services and research for adult blindness versus childhood blindness. One hopes that, now that the World Health Organization (WHO) and International Agency for Prevention of Blindness have developed a global initiative to eliminate avoidable blindness and have included childhood blindness as one of its five key areas, this will change.2 In this issue of theBJO (p 1149) Kocur and co-workers report on the causes of severe visual impairment (visual acuity in the better eye less than 6/60) ...

Bluetoothing androids to shout at blind people • The RegisterBluetoothing androids to shout at blind people • The Register
American researchers have developed a Bluetooth-based system which would allow blind people to hear information about their immediate surroundings in the same way that others read posters, signs or notices.. The Talking Points system was developed at the University of Michigan, and will be presented at international conferences in the UK and Korea next week.. Talking Points can be viewed as a first step in the direction of an audio virtual reality designed for people with blindness and very useful to the sighted community as well, according to James Knox of the U Mich electrical engineering and computer science department.. The idea is that simple bluetooth beacons, probably in plugtop format, could be sold for less than $20. The beacon would have a unique serial number, which would be the only information it transmitted.. The purchaser of a beacon would then be able to log into a website and input information referenced to the beacon number. This could be an advert for a business, a ...

AIMS To determine the anatomical site and underlying causes of blindness and severe visual impairment in children under 16 years of age in special education in the Peoples Republic of China with a view to determining potentially preventable and treatable causes.. METHODS A national study of children attending schools for the blind in China was conducted between April and June 1998 using the WHO Prevention of Blindness Programme (WHO/PBL) eye examination record for children with blindness and low vision. Eight Chinese ophthalmologists attended a training workshop before conducting the study. 36 blind schools in 18 provinces of China were included.. RESULTS 1245 children aged between 5 and 15 years were examined, of whom 1131 (91%) were blind or severely visually impaired (visual acuity less than 6/60 in the better eye). The commonest anatomical sites of visual loss were whole globe (mainly microphthalmos) 25.5% and retina (mainly dystrophies) 24.9%. Lens was the major site in 18.8%, optic nerve ...

On World Sight Day, eye care organisations around the world take note of new data that shows that global eye care efforts are at serious risk of being overwhelmed-unless we act now. New data published in the Lancet Global Health shows that decades of declining avoidable blindness-those with uncorrected refractive errors and cataract-is plateauing, and is projected to increase between 2015 and 2050.. The International Agency for the Prevention of Blindness (IAPB), an international alliance of eye care organisations, has launched the IAPB Vision Atlas with the latest global data and evidence on blindness and vision impairment this World Sight Day (12 October 2017).. A new paper by the Vision Loss Expert Group (VLEG) published yesterday in the Lancet Global Health identifies the leading causes of Blindness and Moderate and Severe Vision Impairment (MSVI) in 2015. Of the 253 million people who are blind or MSVI, uncorrected refractive errors (123.8 million people) and cataract (65.2 million) are ...

The hippocampus has exhibited navigation-related changes in volume and activity after visual deprivation; however, the resting-state functional connectivity (rsFC) changes of the hippocampus in the blind remains unknown. In this study, we focused on sub-region-specific rsFC changes of the hippocampus and their association with the onset age of blindness. The rsFC patterns of the hippocampal sub-regions (head, body and tail) were compared among 20 congenitally blind (CB), 42 late blind (LB), and 50 sighted controls (SC). Compared with the SC, both the CB and the LB showed increased hippocampal rsFCs with the posterior cingulate cortex, angular gyrus, parieto-occpital sulcus, middle occipito-temporal conjunction, inferior temporal gyrus, orbital frontal cortex, and middle frontal gyrus. In the blind subjects, the hippocampal tail had more extensive rsFC changes than the anterior hippocampus (body and head). The CB and the LB had similar changes in hippocampal rsFC. These altered rsFCs of the hippocampal

Diseases affecting the cornea are a major cause of blindness worldwide, second only to cataract in overall importance. The epidemiology of corneal blindness is complicated and encompasses a wide variety of infectious and inflammatory eye diseases that cause corneal scarring, which ultimately leads to functional blindness. In addition, the prevalence of corneal disease varies from country to country and even from one population to another. While cataract is responsible for nearly 20 million of the 45 million blind people in the world, the next major cause is trachoma which blinds 4.9 million individuals, mainly as a result of corneal scarring and vascularization. Ocular trauma and corneal ulceration are significant causes of corneal blindness that are often underreported but may be responsible for 1.5-2.0 million new cases of monocular blindness every year.. ...

Epidemiology of blindness in children | Archives of Disease in ChildhoodEpidemiology of blindness in children | Archives of Disease in Childhood
An estimated 14 million of the worlds children are blind. A blind child is more likely to live in socioeconomic deprivation, to be more frequently hospitalised during childhood and to die in childhood than a child not living with blindness. This update of a previous review on childhood visual impairment focuses on emerging therapies for children with severe visual disability (severe visual impairment and blindness or SVI/BL).. For children in higher income countries, cerebral visual impairment and optic nerve anomalies remain the most common causes of SVI/BL, while retinopathy of prematurity (ROP) and cataract are now the most common avoidable causes. The constellation of causes of childhood blindness in lower income settings is shifting from infective and nutritional corneal opacities and congenital anomalies to more resemble the patterns seen in higher income settings. Improvements in maternal and neonatal health and investment in and maintenance of national ophthalmic care infrastructure are ...

More than 40 million people in the developing world cant see their children, parents, and friends because they are blind, yet most blindness can be prevented or cured with inexpensive medicine or operations. With our partners we have the medicines and medical know-how to give millions of people the gift of sight. But do you and I have the will?. Many cures for blindness are tragically simple. Trachoma infection causes horrible pain, scarring and eventually blindness… and it affects millions of children around the world. But a simple $8 operation can fix these problems, sparing a child years of infections resulting in a lifetime time in the dark. Cataract surgery, to replace the eyes cloudy lens and restore sight, costs $28 for an adult, $121 for a child.. We have the power to stop the tragedy of needless blindness by urging the international community to increase assistance for medicine and medical care that can cure or prevent blindness, and by creating opportunities for blind people who ...

Nigeria national blindness and visual impairment survey - ICEH newNigeria national blindness and visual impairment survey - ICEH new
Nigeria is among the ten most populated countries in the world. Despite its size there had been no earlier national estimate of the prevalence and causes of blindness and visual impairment before the Nigeria national blindness and visual impairment survey was conducted between 2005 and 2007. Six collaborating institutions took part and ICEH provided technical guidance for the survey design, provision of training, external supervision of the survey activities, data analysis and report writing.. As a result, for the first time scientifically valid data are available for the entire country providing the epidemiological evidence and data needed for eye care planning, priority setting, advocacy and for measuring the impact of service delivery in Nigeria. The data also contribute towards the global database of blindness, which is being used for global planning, advocacy, resource mobilisation and to monitor VISION 2020 initiatives.. ...

Artificial retina implant brings hope to blind people - Volume 5 Issue 5: Disability News and Information Service for IndiaArtificial retina implant brings hope to blind people - Volume 5 Issue 5: Disability News and Information Service for India
D.N.I.S. News Network U.S. Researchers recently revealed that a tiny electrical implant that attaches to the retina may some day restore partial sight to millions of people who lose sight by age-related macular degeneration.. At the Annual Meeting of the American Association for the Advancement of Science in San Fransisco, the researchers stated that the device is part of a new class of smart prostheses that link with the brain and nervous system to restore function lost to disease or injury. The artificial retina is designed to take the place of photoreceptor cells in the brain that are charged with capturing and processing light. Professor of Ophtalmology at the University of Southern California Dr. Mark Humayun said, We anticipate this technology will help blind patients who have lost their sight through macular degeneration. Dr. Humayun and is colleagues have joined hands with the privately held Second Sight Medical Products to develop the implant, which has just got clearance from U.S. ...

6 Things You Can Do To Prevent Avoidable Blindness - How Nigeria News6 Things You Can Do To Prevent Avoidable Blindness - How Nigeria News
According to the International Classification of Diseases - 10 (ICD-10), four levels of visual function have been described viz normal vision, moderate visual impairment, severe visual impairment and lastly blindness. Hence, blindness represents the worst case scenario in the spectrum of visual function. Moderate and severe visual impairment are collectively referred to as Low Vision whereas blindness essentially refers to a complete loss of vision.. In the light of the enormous burden of visual impairment especially in the developing countries, the World Health Assembly under the aegis of the World Health Organization instituted an action plan to facilitate universal access to eye health. The aim was to achieve at least 25% reduction in the number of cases of preventable visual impairment by 2019 ...

Last year Conchita Hernández hosted a blindness workshop in the border town of McAllen, Texas. She wasnt sure how many people would show up. McAllen sits on the US border with Mexico, a city surrounded on all sides by government checkpoints - a civic purgatory for undocumented immigrants who cant move back or forward. It wasnt clear how many blind students there were in McAllen, but, when a quality service is offered, word spreads. Sixteen families showed up, each united by the same pursuits: healthier options, better information, and a better life for their blind children.. Life is not perfect for blind children in South Texas, and many blind children still do not qualify for services in the American system because of their immigration status. The prospects in Mexico, however, are worse. Blindness alone is not a qualifier for asylum, and so many families with blind children attempt to cross the border on their own. One case, in Nogales, AZ in April, saw a blind 6-year-old and her 4-year-old ...

Developments in cataract surgery: past, present and future | Points de Vue | International Review of Ophthalmic OpticsDevelopments in cataract surgery: past, present and future | Points de Vue | International Review of Ophthalmic Optics
In spite of amazing technical progress, cataracts remain the leading cause of blindness in the world, affecting almost half (45%) of the 40 to 45 million blind people worldwide according to the WHO, this number increases to 180 million when people with «visual deficiency» are included [9, 10].. Evidently, cataracts pertain to the 80% of cases of blindness that are considered avoidable and, in developed countries, they are no longer a major cause of irreversible blindness. Nowadays, for example, cataracts are considered to be the principal pathology in not much more than 2% of the affiliates of ONCE (Spanish National Organization for the blind [11]). In spite of this, demographic growth and increase in life expectancy, growing more rapidly than the availability of modern surgical treatment in vast areas of the world, will cause cataracts to contribute considerably to the increase of the total number of blind people in the world, the number of whom is estimated to reach 100 million by about 2020 ...

The investigators will use passive repetitive tactile stimulation over a period of 3 months, one hour a day for five days a week, with vertical, horizontal and oblique lines generated randomly by a tactile stimulator. Our aim is (a) to study if repetitive tactile stimulation can create cross-modality and improve recognition and localization of patterns in blind people, (b) to evaluate the impact of this training on brain activity the investigators performed high-density scalp EEG recording during the initial stimulation session and in the last one. And (c) measure the functional connectivity of the brain with resting state MRI pre and post training. The resting state MRI protocol consist on one run of T1WI and three bold runs (TE=30ms,TR=3000ms, flip angle 90º,voxel size 3mm, 124 time points, 0 gap).. Cross-modality sensory stimulation may offer a good opportunity to improve recognition, localization and navigation in blind people.

Ive been a science geek for as long as I can remember. We talk about there being no limits. Although I grew up blind, the idea was never planted in my head that there could be limits in the first place.

by Donna J. Jodhan Would it be fair to say that in general, the blind community could be one of the most misunderstood groups? If so, then why? Could it be that we are misunderstood because maybe and just maybe, the mainstream society has probably not taken enough time to get to know us? Or maybe is it because that they have not been exposed to our world enough? I guess that we could probably offer several explanations for this but at the end of the day, this is the situation. As for my humble opinion, I offer these possibilities: I believe that when it comes to blind people in general, most of our mainstream society have somehow managed to erect artificial barriers towards us. These would include attitude, perception, and belief. Let us first look at attitude. There seems to exist an attitude from many mainstream people that blind people should probably be viewed as not being fully able to be contributors to society. In short, we may be viewed more as people who need to be helped rather than as ...

in the field can understand. This model of blindness is expressed through heartfelt concerns about security and safety, and even by enforced custody and care. Clients of agencies holding this view of blindness will generally be passive, minimally involved in training and marginally employed, often in a sheltered setting; and regardless of how many services they receive, they will usually be seen to need even more.. The second view for blindness is in the minority, but it is the one we do our best to apply at the Colorado Center for the Blind. We consider blindness to be a physical characteristic and little more. Its problems, for the most part, are rooted in social attitudes each of us has internalized to such an extent that the problems attributed to blindness seem real. Since blind people are already using safe and effective methods of daily living, independent travel and communication, we think the problems of blindness are best addressed through an active program of individual skills ...

Jageland Hampus, a Swedish designer, has developed a spice range targeted towards the visually impaired: I decided to create an identity, packaging, and product design, which is suitable for blind people as well as visually impaired. Blind people cook just as much as people who are visually able, but to make it easier for them, they use a number of different methods including placing text in Braille on all of their products. The identity logo I designed for the ingredient range is made out of the Braille representation of the letters a and b. Consequently, by only using the elements that is building up the regular letters a and b, Hampus communicated the name of the ingredient range in a strong and simplistic way, which both can be read by blind and visual able.

Change Blindness ImagesChange Blindness Images
Abstract: Change blindness refers to human inability to recognize large visual changes between images. In this paper, we present the first computational model of change blindness to quantify the degree of blindness between an image pair. It comprises a novel context-dependent saliency model and a measure of change, the former dependent on the site of the change, and the latter describing the amount of change. This saliency model in particular addresses the influence of background complexity, which plays an important role in the phenomenon of change blindness. Using the proposed computational model, we are able to synthesize changed images with desired degrees of blindness. User studies and comparisons to state-of-the-art saliency models demonstrate the effectiveness of our model ...

Blindness can be defined physiologically as the condition of lacking sight. The definition as it applies to people thus legally classified is, however, more complex. The term blindness also applies to partial visual impairment: In North America and most of Europe, legal blindness is defined as vision of 20/200 (6/60) or less in the better eye with correction. People with normal acuity who nonetheless have a visual field of less than 20 degrees - the norm being 180 degrees - are also classified as being legally blind. The World Health Organization (WHO) defines legal blindness as vision of 20/400 (3/60) or less in the better eye with correction. They also accept people with a visual field of less than 10 degrees under that heading. Approximately ten percent of those classified as being legally blind are actually sightless. The rest have some vision, from light perception alone to relatively good acuity. ...

Researchers reverse congenital blindness in mice - IMPC | International Mouse Phenotyping ConsortiumResearchers reverse congenital blindness in mice - IMPC | International Mouse Phenotyping Consortium
Researchers funded by the National Eye Institute (NEI) have reversed congenital blindness in mice by changing supportive cells in the retina called Müller glia into rod photoreceptors. The findings advance efforts toward regenerative therapies for blinding diseases such as age-related macular degeneration and retinitis pigmentosa. A report of the findings appears online today in Nature. NEI is part of the National Institutes of Health.. This is the first report of scientists reprogramming Müller glia to become functional rod photoreceptors in the mammalian retina, said Thomas N. Greenwell, Ph.D., NEI program director for retinal neuroscience. Rods allow us to see in low light, but they may also help preserve cone photoreceptors, which are important for color vision and high visual acuity. Cones tend to die in later-stage eye diseases. If rods can be regenerated from inside the eye, this might be a strategy for treating diseases of the eye that affect photoreceptors.. Photoreceptors are ...

Cortical blindness and Anton syndrome in a patient with obstetric hemorrhage<...Cortical blindness and Anton syndrome in a patient with obstetric hemorrhage<...
TY - JOUR. T1 - Cortical blindness and Anton syndrome in a patient with obstetric hemorrhage. AU - Argenta, Peter A. AU - Morgan, Mark A.. PY - 1998/5. Y1 - 1998/5. N2 - Background: Cortical blindness is characterized by loss of vision in the presence of intact anterior visual pathways. Anton syndrome, a form of anosognosia, is a rare complication of cortical blindness involving compromise of the visual association centers, with resulting patient denial of blindness. Both syndromes have been associated with computed tomography findings of localized cortical ischemia. In most cases, both the clinical and radiologic features are reversible. Case: A woman with hemorrhage from an incomplete abortion at 21 weeks experienced cortical blindness and visual anosognosia. Conclusion: Cortical blindness and anosognosia are unusual manifestations of severe hemorrhage but should be considered in the differential diagnosis of a patient with atypical visual symptoms.. AB - Background: Cortical blindness is ...

Cortical blindness - WikipediaCortical blindness - Wikipedia
The prognosis of a patient with acquired cortical blindness depends largely on the original cause of the blindness. For instance, patients with bilateral occipital lesions have a much lower chance of recovering vision than patients who suffered a transient ischemic attack or women who experienced complications associated with eclampsia.[2][3] In patients with acquired cortical blindness, a permanent complete loss of vision is rare.[2] The development of cortical blindness into the milder cortical visual impairment is a more likely outcome.[2] Furthermore, some patients regain vision completely, as is the case with transient cortical blindness associated with eclampsia and the side effects of certain anti-epilepsy drugs. Recent research by Krystel R. Huxlin and others on the relearning of complex visual motion following V1 damage has offered potentially promising treatments for individuals with acquired cortical blindness.[10] These treatments focus on retraining and retuning certain intact ...

Double dissociation in monocular blindness: Enhanced contrast but impaired motion perception | JOV | ARVO JournalsDouble dissociation in monocular blindness: Enhanced contrast but impaired motion perception | JOV | ARVO Journals
Previous research has shown that early monocular blindness from unilateral enucleation (surgical removal of one eye) results in equivalent or enhanced form perception but impairments in aspects of motion processing (see Steeves et al., 2008). To further investigate the effects of early monocular blindness on form and motion processing, we compared binocularly and monocularly viewing controls to individuals who were unilaterally enucleated within the first few years of life. Thresholds were measured on three tasks that had not before been tested in this population; 1) contrast discrimination, 2) horizontal speed discrimination, and 3) horizontal coherent motion discrimination. Preliminary data are consistent with previous research showing early monocular blindness results in equivalent or enhanced sensitivity compared to binocularly and monocularly viewing controls at some contrasts. It also results in higher motion discrimination thresholds for lower speeds and a nasalward bias in the perception ...

Legal blindness in normal tension glaucoma: a subgroup analysis | IOVS | ARVO JournalsLegal blindness in normal tension glaucoma: a subgroup analysis | IOVS | ARVO Journals
Purpose : To compare the probability of going blindness between low and high maximum intraocular pressure (IOP) groups in eyes with normal tension glaucoma (NTG). Methods : We retrospectively investigated 380 patients diagnosed as bilateral NTG between 1985 and 2007, and followed for at least 5 years. We reviewed the patients data of best-corrected visual acuity and visual field from our records. A cut-off value of maximum IOP was tentatively set as 18 mmHg. The blindness was defined according to the World Health Organization (WHO) criteria. The probabilities of blindness were calculated using Kaplan Meier life-table analyses. Results : The mean age at diagnosis was 55.8 ± 11.8 years. Men were 158, and women were 222. The mean follow-up period was 14.0 ± 5.7 years. The low IOP group included 205 patients (53.9%). Nineteen patients (5.0%) had already had unilateral blindness due to glaucoma at diagnosis. Twenty-two cases (12.6%) in the high IOP group and 16 cases (7.8%) in the low IOP group ...

Cataract Blindness In India | HelpMeSee India FoundationCataract Blindness In India | HelpMeSee India Foundation
India has made huge strides from 2007 to 2019 in improving vision care according to Health Ministry with a reduction of the prevalence of blindness by 47% and a reduction in visual impairment by 51.9% . India has additionally reduced the number of blind from 12 million to 4.8 million during that same period. Despite this phenomenal success, cataracts continue to be a challenge.. In those 50 to 90 years of age, cataracts contribute to 66.2% of overall blindness, 80.7% of visual impairment and 70.2% moderate visual impairment. Additional causes of blindness include glaucoma at 5.50% and corneal opacity at 7.40%. Interestingly, 7.2% of blindness in India is due to complications from cataract surgery. Improvements in the quality of cataract surgery training quality should reduce this last number.. Today, there are 116 million Indian citizens aged 60 years or older. 15.42% currently suffer from visual disabilities. By 2050 the number of Indian senior citizens will increase to 330 million.

Leber congenital amaurosis (LCA) accounts for approximately 15 % of congenital blindness. This largely recessively inherited disorder manifests with signs of very poor visual function and roving eye movements or nystagmus. Eye-poking or eye-rubbing, the oculodigital sign, may be present and may eventually lead to sunken orbits, cataract and keratoconus. The majority of patients have normal fundi at presentation, but disc pallor, vessel attenuation and pigmentary changes may follow. The ERG is typically severely reduced or undetectable from early infancy (Fig. 9.2B).. Was this article helpful?. ...

Amygdala Activation for Eye Contact Despite Complete Cortical Blindness | Journal of NeuroscienceAmygdala Activation for Eye Contact Despite Complete Cortical Blindness | Journal of Neuroscience
Cortical blindness refers to the loss of vision that occurs after destruction of the primary visual cortex. Although there is no sensory cortex and hence no conscious vision, some cortically blind patients show amygdala activation in response to facial or bodily expressions of emotion. Here we investigated whether direction of gaze could also be processed in the absence of any functional visual cortex. A well-known patient with bilateral destruction of his visual cortex and subsequent cortical blindness was investigated in an fMRI paradigm during which blocks of faces were presented either with their gaze directed toward or away from the viewer. Increased right amygdala activation was found in response to directed compared with averted gaze. Activity in this region was further found to be functionally connected to a larger network associated with face and gaze processing. The present study demonstrates that, in human subjects, the amygdala response to eye contact does not require an intact ...

SARMA: Dialogues on blindness II.SARMA: Dialogues on blindness II.
The word blindness refers to a range of visual impairments that cause a severe to total reduction of the experience of sight. It is also charged as a metaphor, blindness being a synonym of ignorance or not-knowing. Over the ages, both meanings got also mixed up, whether deliberately or out of convenience, blindness was romanticised and invested with misconceptions. And more recently in cultural theory, the blind spot has become an omnipresent metaphor to reflect upon the limitations of our perception, knowledge and opinions. Yet it is not my aim here to deconstruct the term blindness and apply a strategy against interpretation to it. Rather to explore its potential within the field of the performing arts, through a series of dialogues with artists. Interestingly, a large number of dancers and choreographers have broached the issue in the past decades: through working with blind people, as Anne Kilcoyne and Steve Paxton in Touchdown Dance (since 1986) or Wim Vandekeybus in Her Body ...

The World Sight Day Challenge, slated to take place on October 9, 2014 is an annual awareness day that aims to focus global attention on blindness and vision impairment worldwide.. The day aims to create awareness that blindness can be avoided if there is universal access to quality vision and eye care services for all those in need. Worldwide, many cases of vision impairment are simply due to the lack of a pair of eye glasses that would help correct a refractive error. The underlying vision of the campaign is to ensure that the quality-of-life and future livelihood of children and adults is not impacted because they do not have sufficient eye care.. According to Optometry Giving Sight, the organization overseeing the campaign, over 600 million people around the globe do not have access to the eye care and eyewear they need.

Amaurosis fugax | MetaAmaurosis fugax | Meta
Presentation of the etiology, diagnosis, possible complications and treatment of amaurosis fugax. amaurosis fugax is a transient monocular loss of vision, usually affecting the entire visual field. Amaurosis fugax is caused by transient retinal ischemia resulting from embolism, hemodynamic insufficiency or ocular vascular disease. In view of the high complication rate (annual blindness rate 1%, annual risk of an ischemic insult 2%, myocardial infarction 30%, and an 18% mortality rate), an immediate search for the underlying causes is mandatory. Diagnostic evaluation should include ophthalmological, neurological and cardiovascular investigations. Management of amaurosis fugax comprises, in the first instance, treatment of the underlying disease and administration of anti-platelet agents. In cases in which stenosis of extracranial vessels presents, endarterectomy may sometimes be considered. ...

KCNJ13 Gene Augmentation Therapy to Treat Blindness due to Kir7.1 Defects | IOVS | ARVO JournalsKCNJ13 Gene Augmentation Therapy to Treat Blindness due to Kir7.1 Defects | IOVS | ARVO Journals
Purpose : Mutations in the KCNJ13 gene, encoding the inwardly rectifying potassium Kir7.1 ion-channel in the RPE, cause autosomal dominant snowflake vitreoretinal degeneration (SVD) and autosomal recessive Lebers congenital amaurosis (LCA16). Molecular and biophysical analysis of the mutant protein revealed a non-functional protein product. With a goal of restoring retinal function via gene augmentation therapy, we tested the efficacy of Kir7.1 channel functional rescue using an in vitro model of CHO cells expressing disease - associated mutations. Methods : We cloned human Kir7.1-WT (wild-type) and W53X (mutant) into Flip-In™ expression vector (ThermoFisher Scientific) and transfected them into Chinese Hamster Ovary (CHO) cells to express the protein products. Expression of Kir7.1 was verified through PCR and Restriction fragment length polymorphism (RFLP) analysis. Whole-cell configuration of patch-clamp technology was used to measure Kir7.1 current. Protein expression was confirmed by ...

Legal Blindness in the United States, where normal vision is considered to be 20/20, legal blindness is defined as visual acuity with best correction in the better eye worse than or equal to 20/200 or a visual field extent of less than 20 degrees in diameter. Most states use these standards to provide rehabilitation services and benefits to people who are visually impaired. Some of these benefits and services include an IRS income tax exemption, free telephone directory assistance, free Talking Book Library Services through the National Library Service and Vocational and Independent Living Services through individual state programs. Please note the term Legal Blindness does not mean that a legally blind person is blind or has no usable vision. Most people defined as legally blind have usable vision and can perform most daily tasks with the use of special glasses or low vision aids ...

Several studies have shown that rehabilitation can augment the brains inherent plasticity (Eickhoff et al., 2008; Kao et al., 2011; Martinez et al., 2009; Merabet & Pascual-Leone, 2010; Schlaug et al., 2009; Schneeberger et al., 2006, 2007). We are only beginning to understand how this finding applies to the use of AVDs in the field of artificial vision. New vision technology and efforts at ocular regeneration offer the eventual promise of meaningful improvement in the lives of people who are blind. However, this burgeoning field risks failure unless appropriate rehabilitative components are developed and multidisciplinary involvement occurs. Our results show that without instruction, the blind participants performed no better than chance when using the BrainPort vision device. However, after even a short amount of directed training in core skill acquisition, performance on the majority of outcomes significantly improved. Moreover, the scores for object and word recognition continued to improve ...

Snow blindness symptoms Reston VASnow blindness symptoms Reston VA
While some people may worship sun, sand, and beaches, youd trade all of that away in exchange for a day on the slopes. Winters your season - the snow is fresh, theres always a mug of hot cocoa to enjoy, and theres nothing better than cozying up in a warm sweater.. Before you start making the most of winter, however, its important to be aware of one of the biggest dangers to your eyesight this winter…Snow blindness.. What is Snow Blindness?. Snow blindness - also known as photokeratits - is a painful, potentially severe eye condition that occurs when your eyes come into contact with UV rays. The reason why this condition became known as snow blindness is because UV rays bounce off the surface of snow, thus increasing the strength of the UV rays. When these rays hit your eyes, they burn the surface layer of the cornea.. Snow blindness can also refer to what happens when your eyes are exposed to too much cold, dry air. The corneas surface can freeze when in contact with cold, dry air for ...

AN ANALYSIS OF PLANT BLINDNESS IN TURKISH TEXTBOOKS USED AT THE BASIC EDUCATION LEVEL | Journal of Baltic Science EducationAN ANALYSIS OF PLANT BLINDNESS IN TURKISH TEXTBOOKS USED AT THE BASIC EDUCATION LEVEL | Journal of Baltic Science Education
The importance of plants is not as clearly understood as that of animals. This lack of attention is called plant blindness and is considered one of the most important problems in biology education. Textbooks do not put much emphasis on plants and, therefore, they may contribute to plant blindness. In this research, ten textbooks used for teaching at the basic education level in Turkey were analyzed for plant blindness using the document analysis method. The words and photographs associated with plants and animals were analyzed. The data analysis did not find any evidence that could lead to a conclusion of plant blindness based on the text and photos of these textbooks. However, if the number of plant and animal species covered is increased, and more words and photos are used to introduce these species, children will become more familiar with plants and animals. Besides textbooks, other educational tools can be analyzed in terms of plant blindness to expand on the related literature.. ...

The first part of the study is observational, in which the body clock rhythms of blind individuals are assessed for variability in patterns across subjects. The second part of the study involves a melatonin treatment (0.025-20 mg). The dose for each subject will be determined by the previous, observational data collected on the specifics of their individual body clock. The purpose of the intervention is to find an optimized dosing regimen and administration time to synchronize the body clocks of blind individuals, that seem to operate independent of the 24-hour environmental light/dark cycle, to the 24-hour day ...

The Marrakesh Treaty to Facilitate Access to Published Works for Persons Who Are Blind, Visually Impaired, or Otherwise Print Disabled (MVT) is the latest addition to the body of international copyright treaties administered by WIPO. It has a clear humanitarian and social development dimension and its main goal is to create a set of mandatory limitations and exceptions for the benefit of the blind, visually impaired and otherwise print disabled (VIPs).. It requires Contracting Parties to introduce a standard set of limitations and exceptions to copyright rules in order to permit reproduction, distribution and making available of published works in formats designed to be accessible to VIPs, and to permit exchange of these works across borders by organizations that serve those beneficiaries.. The Treaty clarifies that beneficiary persons are those affected by a range of disabilities that interfere with the effective reading of printed material. The broad definition includes persons who are blind, ...

TY - JOUR. T1 - Change blindness. AU - Simons, Daniel J.. AU - Levin, Daniel T.. PY - 1997/10. Y1 - 1997/10. N2 - Although at any instant we experience a rich, detailed visual world, we do not use such visual details to form a stable representation across views. Over the past five years, researchers have focused increasingly on change blindness (the inability to detect changes to an object or scene) as a means to examine the nature of our representations. Experiments using a diverse range of methods and displays have produced strikingly similar results: unless a change to a visual scene produces a localizable change or transient at a specific position on the retina, generally, people will not detect it. We review theory and research motivating work on change blindness and discuss recent evidence that people are blind to changes occurring in photographs, in motion pictures and even in real-world interactions. These findings suggest that relatively little visual information is preserved from one ...
