• Cerebral Palsy

  Types of Vision Impairment Associated with Cerebral Palsy Causes of visual impairment in children with cerebral palsy are broken up into issues related to the eye, and those related to the brain. [cerebralpalsyguidance.com]

  (B) Cerebral palsy. (C) Epilepsy. (D) Autism. [definitions.uslegal.com]

  Accompanying features of CVI include cerebral palsy and developmental delays. In many cases, partial recovery of vision is possible. Boston Children's Hospital has been named the #1 children's hospital in the nation by U.S. [childrenshospital.org]

  The resulting cerebral visual impairment is a hidden disability. Unlike cerebral palsy, it cannot be seen. Yet it can be disabling, frustrating and lead to social difficulties. It is obviously not possible to learn from what cannot be seen. [cvisociety.org.uk]

• Epilepsy

  In some patients, the link between the epilepsy and the visual impairment was not appreciated until they attended an epilepsy clinic. KEYWORDS: cortical blindness; drug-resistant epilepsy; ulegyria [Indexed for MEDLINE] Free full text [ncbi.nlm.nih.gov]

  (C) Epilepsy. (D) Autism. [definitions.uslegal.com]

  Nearly two-thirds of children with vision impairment also have one or more other developmental disabilities, such as mental retardation, cerebral palsy, hearing loss, or epilepsy. [foxcenter.pitt.edu]

• Night Blindness

  Night Blindness Night blindness results in inability to see outside at night under starlight or moonlight or in dimly lighted interior areas such as movie theaters or restaurants. [coavision.org]

  Students experience night blindness, that may be followed by loss of peripheral vision (initially as ring-shaped defect), progressing over many years to tunnel vision and finally blindness. Students typically need high illumination. [teachingvisuallyimpaired.com]

  It often leads to severe visual impairment and sometimes total blindness. People with RP first develop noticeable symptoms in childhood or their teens. The first symptom most people notice is night blindness. [support.freedomscientific.com]

• Social Isolation

  To be visually impaired after stroke reduces quality of life and causes social isolation because of difficulties in navigating/orientating in the surroundings. [ncbi.nlm.nih.gov]

  For one, there may be the fear of social isolation; for another, not being able to do the crossword. [patient.info]

  Common causes CVI in infants and young children include: hypoxic ischemic encephalopathy (HIE) (in the term born infant) periventricular leukomalacia (PVL) (in the preterm infant) traumatic brain injury due to shaken baby syndrome and accidental head [childrenshospital.org]

  Cortical Visual Impairment can be the result of a variety of different medical causes including hypoxic ischemic encephalopathy (HIE) in full-term babies, periventricular leukomalacia (PVL) in premies, traumatic brain injury, epilepsy and other causes [wonderbaby.org]

  Encephalopathy includes visual impairment caused by brain injuries, and postoperative impairment from brain tumors. [intechopen.com]

VEPs were also severely abnormal in the infants with the worst visual outcome, but were not providing a more reliable prognosis. [ncbi.nlm.nih.gov]

Prognosis The prognosis generally relates to the severity of the impairment and the ability of the aids to correct it. A good low vision exam is important to be aware of the latest low vision aids. [medical-dictionary.thefreedictionary.com]

It is important to note that not all researchers agree on the full range of causes, the prognosis or even the proper diagnostic label used to describe vision loss due to brain damage. [tech.aph.org]

Conclusions: About one-sixth of IADL limitations and one-fifth of social participation restrictions could be prevented by an optimal optical correction. These results underline the importance of eye examinations in older adults to prevent disability. [ncbi.nlm.nih.gov]

Some conditions such as Cataract and Uncorrected Refractive Error are certainly treatable and Trachoma is undoubtedly preventable. [atlas.iapb.org]

Currently, the most common form of vision loss, macular degeneration, is neither preventable nor curable (but early detection and appropriate treatment can prevent blindness). Irreversible vision loss is twice as common as dementia. [visualimpairment.org.nz]

Key facts Globally, at least 2.2 billion people have a vision impairment or blindness, of whom at least 1 billion have a vision impairment that could have been prevented or has yet to be addressed. [who.int]
