In-Depth Presently, Cortical Visual Impairment (CVI) is the most common cause of permanent visual impairment in children (1-3). [childrenshospital.org]

After presentation, the test card was removed and the patient was asked to fixate on the grey background and to describe the duration and colour of any after-images. Each colour was presented three times at each presentation duration. [jnnp.bmj.com]

For this reason it is important to give your child enough time when presenting an object. Difficulty with visual complexity. Children with CVI need simplicity. First, it is important that the object presented is simple. [littlebearsees.org]

It presents two parallel and interacting approaches: the psychophysical, or determining the relationship between stimuli in the environment and perception, and the physiological, or locating the biological systems responsible for perception. [books.google.com]

• Abnormal Eye Movement

  Examination of the visual system in AD may reveal visual field deficits, prolonged visual evoked potentials, depressed contrast sensitivities, and abnormal eye movement recordings. [collections.lib.utah.edu]

  Brain dysfunction must explain the abnormal visual responses, as abnormal ocular structures, abnormal eye movements, and refractive error do not. [childrenshospital.org]

However, the success of restorative treatments also depends on the way in which different visual maps in the occipital lobe communicate with each other. [york.ac.uk]

Thus, in addition to treatments directed at lowering eye pressure, still the mainstay of glaucoma therapy, there may be opportunities to develop treatments directed at the retina and the brain. [glaucoma.org]

That lack of information has hampered the translation of biologically inspired treatments from preclinical models to effective clinical treatments. [dovepress.com]

Treatment: There is no definite treatment to reverse the damage. Aspirin treatment is effective in reducing systemic vascular events but it does not appear to prevent the involvement of the other eye [ 3 ]. [intechopen.com]

Standard Therapies Treatment The lack of knowledge on the basic biology of the visual snow syndrome has caused a general deficiency of effective treatment strategies for most patients. [rarediseases.org]

Further prognosis depends on the potential existence of an underlying disease. Multiple sclerosis is the most common cause of optic neuritis ! [amboss.com]

Prognosis: The course of the illness results in poor prognosis. Visual loss is generally permanent; partial visual recovery can be achieved by steroid therapy [ 3 ]. [intechopen.com]

Especially found in the elderly, they all have an unfavorable prognosis. The kinetics of tumor growth is superior than that of low-grade gliomas, provoking fast-evolving neurological deficiencies. [em-consulte.com]

In addition, various pathologies that recognize inflammatory, vascular, neoplastic or toxic, metabolic etiology may induce other unnecessary visual system dysfunctions associated with changes in visual perception such as diplopia (paralytic strabisms) [fondazionebietti.it]

However, as Vaivre-Douret et al. (2016) emphasize, the etiology of DCD appears confused on account of the umbrella term of motor dysfunction. [frontiersin.org]
