Presentation
Acute subperiosteal hematoma of orbit is a rare condition and its presentation with rapid severe diminution of vision is even rarest. Urgent intervention is required for these patients presenting with visual compromise. [ncbi.nlm.nih.gov]
[…] for less developed countries and even higher for more developed countries, in the number of persons with presenting visual acuity less than 6/60 as compared with presenting visual acuity less than 3/60 [12, 23, 24]. [bmcmedicine.biomedcentral.com]
Cortical/Cerebral Visual Impairment, Part 1 Webinar | Approximately one hour This first session of the presentation covers the causes, definition and classification of cortical/cerebral visual impairment and is presented by staff of the New England Eye [perkinselearning.org]
Entire Body System
- Inflammation
SOCT may provide objective data of the cellular load of the eyes with posterior segment inflammation. [ncbi.nlm.nih.gov]
Broad categories of conditions that impair vision include infections (e.g., gonorrhea or congenital rubella infection), inflammations (e.g., uveitis ), congenital or hereditary diseases (e.g., retinitis pigmentosa ), tumours, cataracts, trauma or mechanical [britannica.com]
The artery to the optic nerve can be blocked in the same ways and can also be blocked by inflammation (such as may occur with giant cell [temporal] arteritis). [msdmanuals.com]
- Asymptomatic
Marked improvement in vision was observed and at 3 months of follow-up the patient was asymptomatic. [ncbi.nlm.nih.gov]
Health care professionals often recommend that all people should have periodic and thorough eye examinations as part of routine primary care, especially since many eye diseases are asymptomatic. [en.wikipedia.org]
Standardization of qualitative and quantitative imaging criteria will further help in the identification of asymptomatic changes and allow for the use of countermeasures to mitigate potential long-term vision damage. [nasa.gov]

- Surgical Procedure
PURPOSE: Chiasmapexy is a poorly described surgical procedure adopted to correct the downward displacement of suprasellar visual system (SVS) into an empty sella (ES) causing visual worsening. [ncbi.nlm.nih.gov]
In 2019, surgical procedures and corrective lenses can’t correct all of these. Depending on the cause of the impairment, vision can be affected in different ways. [visionsource-avcma.com]
Ears
- Hearing Impairment
RESULTS: Adjusting for sociodemographic factors, hearing impairment and comorbidity, fixed effects regressions revealed that the onset of mild visual impairment decreased the social support score, in particular the emotional support score. [ncbi.nlm.nih.gov]
Hearing impairment is defined as a loss of 70 decibels aided or speech discrimination of less than 50% aided. Visual impairment is defined as 20/200 corrected in the better eye or a visual field of 20 degrees or less. [definitions.uslegal.com]
It is also common for children with visual impairments to also have with additional disabilities such as traumatic brain injury, hearing impairments, physical impairments, or cognitive impairments. [wmich.edu]

Eyes
- Scotoma
Abstract Visual impairment associated with Age-related Macular Degeneration (AMD) often results in a central scotoma which is an alteration in the central vision, leading to distortion or loss of vision. [ncbi.nlm.nih.gov]
This can be caused by a number of different impairments, such as blindness, achromatopsia (color-blindness), hyperopia (far-sightedness), myopia (near-sightedness), and scotoma (blind spots). [webplatform.github.io]
[…] acuity is acceptable for difficult-to-test pupils; and § (b) for pupils not yet enrolled in kindergarten, measured acuity must be significantly deviant from what is developmentally age-appropriate; § (2) visual field of 20 degrees or less, or bilateral scotomas [revisor.mn.gov]
Common problems of the visual field include scotoma (area of reduced vision), hemianopia (half of visual field lost), homonymous hemianopsia and bitemporal hemianopia. [en.wikipedia.org]
Psychiatrical
- Fear
Furthermore, individuals with VI showed a greater fear of falling. [ncbi.nlm.nih.gov]
Experience The blind child is often hesitant to explore because of fear of the unknown. He is also often discouraged from exploration by adults who are overprotective. [tsbvi.edu]
Although they may have a great desire to belong to a group, they may have fears about how to go about it. [intellectualdisability.info]
A visually impaired child may also be hesitant to explore the world around them due to fear of the unknown and also may be discouraged from exploration by overprotective family members. [en.wikipedia.org]

Neurologic
- Confusion
[…] likenesses and minor differences Confuses same word in same sentence Repeatedly confuses similar beginnings and endings of words Fails to visualize what is read either silently or orally Whispers to self for reinforcement while reading silently Returns [sites.trinity.edu]
It is also important to keep the color of materials constant to avoid confusion. This also applies to visual cues in general which should also be consistent over time and location. [sfsu.edu]
Placing a red "cancel" button next to a green "submit" button, for example, might cause visual confusion to a user who is red-green colorblind. [mashable.com]
Even black can be confused as dark green or dark blue. [disabilityinfosa.co.za]
The effects of poor vision in older people are wide reaching and include falls, confusion and reduced quality of life. Much of the visual impairment in older ages can be treated (e.g. cataract surgery, correction of refractive error). [ncbi.nlm.nih.gov]
- Irritability
[…] and waning gray-white lipid depositing in the peripheral, superficial stroma can occur and is known as pseudogerontoxon.[2] Keratoconus has been shown to be more prominent in VKC patients as well; possibly due to increased eye rubbing of chronically irritated [eyewiki.aao.org]

Workup
After additional workup including lumbar puncture with an opening pressure of 55 cm H2O, a diagnosis of IIH was confirmed. [ncbi.nlm.nih.gov]
Treatment
The mutant constructs could not rescue the PGAP1-deficient CHO cell lines resistance to PI-PLC treatment. [ncbi.nlm.nih.gov]
See the Health A-Z topic on: Macular degeneration - treatment for more information about the treatment options for dry and wet AMD. [hse.ie]
Prognosis
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]
Etiology
The potential etiologies of postoperative visual loss are reviewed, and recommendations for avoiding this complication are discussed. [ncbi.nlm.nih.gov]
The team observed the development of early and late AMD over a period of around 18 years in the participants of the Atherosclerosis Risk in Communities (ARIC) Study which investigated the etiology and clinical outcomes of atherosclerosis, a disease in [hindi.gujaratfinancialexpress.com]
Epidemiology
Abstract Epidemiological data describing the prevalence of blindness and visual impairment in Haiti are sparse. The Haitian National Committee for the Prevention of Blindness (CNPC) estimates the prevalence of blindness at 1 %. [ncbi.nlm.nih.gov]
Pathophysiology
However, its aetiology and pathophysiology remain unclear. The clinical course of this disease is usually benign and self-limiting, but a minority of patients will face very debilitating and sight threatening complications. [ncbi.nlm.nih.gov]
[…] study exhibited a 4% prevalence in African schoolchildren.[8] The majority of VKC occurs in patients between the ages of 5-25 years old with an age of onset between 10-12 years old; however there are reports of patients as young as 5-months-old.[3][9] Pathophysiology [eyewiki.aao.org]
Prevention
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]
