Whether existing methods of scotopic sensitivity syndrome treatment are appropriate and effective.

Many of these problems are grouped together under the label "scotopic sensitivity syndrome".

She left with the news she had scotopic sensitivity syndrome – also known as visual stress.

She has also claimed that a treatment for scotopic sensitivity syndrome could help a number of incarcerated individuals and delinquent children.

Dark adaptation in disabled readers screened for Scotopic Sensitivity Syndrome.

Skepticism relating to scotopic sensitivity syndrome's exact pathology, has evolved on several fronts:

The school also caters for a small number of pupils with Irlen scotopic sensitivity syndrome, a visual perceptual disorder affecting primarily reading and writing.

The association of scotopic sensitivity syndrome and dyslexia has been challenged by many authors in both the optometric and ophthalmologic communities.

Critics claim that the symptoms of those with Scotopic Sensitivity Syndrome are related to already known visual perceptual and neurological disorders.

Scotopic sensitivity syndrome (also called Irlen Syndrome)

The scotopic sensitivity syndrome is diagnosed by interviewing the client and by observing responses to certain visual tasks such as interpreting geometric figures and reading.

However there is debate over whether this is the only reason for reading disabilities, scotopic sensitivity syndrome, deficits in verbal memory and orthographic knowledge are other proposed factors.

Scotopic sensitivity syndrome is based on the theory that some individuals have hypersensitive photoreceptors, visual pathways, and/or brain systems that react inappropriately to some wavelengths of light.

Critics assert that the term "scotopic sensitivity" is a misnomer given that the symptoms of "Scotopic Sensitivity Syndrome" reportedly occur during photopic conditions.

They are intended to help people with the supposed perceptual processing difficulty known as Irlen Syndrome, also known as Scotopic Sensitivity Syndrome or visual stress.

The method is intended to reduce or eliminate perceptual processing errors; the resultant retiming of visual signals in the brain improves the reading difficulties associated with scotopic sensitivity syndrome.

Irlen Syndrome (also known as Scotopic Sensitivity Syndrome) is a visual-perceptual processing difficulty affecting 15% of the population and about 45% of those people with reading difficulties.

Scotopic sensitivity syndrome, also known as the Irlen Syndrome', is said to be a visual-perceptual defect related to difficulties with light source, glare, luminance, wavelength and black/white contrast.

The book relates Williams' diagnosis with scotopic sensitivity syndrome, and her experience with tinted lenses on her visual perceptual disorders including visual fragmentation, context blindness, face blindness, and loss of depth perception.

According to Helveston, the scotopic sensitivity syndrome and its treatment has, as a phenomenon, resulted in classic group behaviour and has the characteristics of a fad with a charismatic personality as a leader and the supporting evidence being mostly anecdotal.

The Irlen syndrome, occasionally referred to as scotopic sensitivity syndrome (SSS) or Meares-Irlen syndrome, very rarely as asfedia, and recently also as visual stress, is a condition relating to the interaction with light of the central nervous system and the eyes at a physiological level.

A 2009 report by The American Academy of Pediatrics (AAP) does not believe that there is conclusive scientific evidence for the use of coloured lenses (one treatment used to relieve symptoms of Scotopic Sensitivity Syndrome) although it does acknowledge anecdotal evidence to the contrary.
