“…Oculomotor disorders are one of the main targets of rehabilitation in patients with CVI. Rehabilitation allows the child to optimize gaze behaviour and prevent abnormal ocular motility from impairing visual function , Lueck 1999. In particular, treatment improves attention and fixation times, pursuit movements, and the capacity to perform precise saccades as well as the acquisition of environment scanning strategies.…”

The aim of the study was to describe ocular motility in a sample of 56 patients affected by cerebral visual impairment (CVI) of hypoxic‐ischemic origin. The sample consisted of 56 participants (37 males and 19 females), ranging in age from 2 to 16 years. In all cases CVI was associated with MRI‐verified damage of the cerebral visual system. A complete ophthalmologic and neurological assessment was performed. Behaviour of gaze was studied in four conditions: during scanning of the surrounding environment, during fixation, execution of saccades, and pursuing. In addition, strabismus, nystagmus, and paroxysmal ocular deviations were evaluated. Ocular motility was studied by video recording the patients’eye motility during orthoptic examination. Each pattern of ocular motility studied revealed profound alterations in all the individuals examined. Typical features of ocular motility in CVI were: paroxysmal ocular deviations (present in 78%); the presence of variable angle strabismus (86%); and defective coordination of saccades (93%). Exploration of the environment and fixation were also impaired (88% and 84%, respectively). Disorders of initiation and performing saccades, absence of smooth pursuit, vergence abnormalities, nystagmus beats, instability of fixation, and difficulty in the systematic exploration of the environment were observed. These abnormalities characterize lack of gaze coordination found in children with brain damage. An early and detailed evaluation of ocular motility in individuals with CVI is important, especially when rehabilitation intervention is intended.

“…In addition, most children with CVI have other neurological sequelae, including cerebral palsy and hearing impairment, which complicates their rehabilitation and education (Flanagan et al, 2003;Good, 2001;Malkowicz et al, 2006). Thus, a team approach often works best when educating children with CVI (Flanagan et al, 2003;Lueck, Hart, & Dornbusch, 1999).…”

“…Internal, external, and social validity were discussed. Lueck, Dornbusch, and Hart (1999) They used an A-B-A single subject design. The child showed significant improvement in his visual skills, however, concurrent with his treatment he began a new seizure medication that decreased seizure activity and increased alertness.…”

“…Effective interventions were examined in very few studies (Baker-Nobles & Rutherford, 1995;Farrenkopf, McGregor, Nes, & Koenig, 1997;Lueck, Dornbusch, & Hart, 1999). While these early results were promising, future studies need to look at a wider variety of children at varying levels of severity of CVI.…”

The Reliability of the CVI Range: A Functional Vision Assessment for Children with Cortical Visual Impairment

Children identified as visually impaired under the Individuals with Disabilities Education Act (IDEA) need to have a functional vision assessment to determine how the visual impairment affects educational performance. Most current functional vision assessments have been based on the needs of children with ocular visual impairments (children with damage to the eye structures). Children with visual impairment due to brain damage, or cortical visual impairment (CVI), have unique vision characteristics that are often different from children with ocular visual impairments. Given this situation, Roman-Lantzy (2007) developed The CVI Range for conducting a functional vision assessment of children with CVI. The purpose of this study was to examine the reliability of The CVI Range. In this study, 104 children were assessed with The CVI Range. Twenty-seven children were tested by two examiners to determine inter-rater reliability; 20 children were tested on two occasions to determine the test-retest reliability; and 57 children were tested one time by a single examiner. The CVI Range had an internal consistency measure or alpha of .96. The inter-rater reliability coefficient was .98 and the test-retest reliability coefficient was .99. In addition, the CVI Range has two sections that are scored differently and the scores from the two sections were compared to determine if they provided similar scores and therefore similar implications for intervention. Kappa, or the index of agreement, for the two parts of the assessment was .88. Results of this study indicate that The CVI Range is a reliable instrument. Future research needs to focus on training requirements related to administration of The CVI Range as well as training of the many professionals that serve children with CVI. Research is also needed to determine appropriate and effective interventions for children with CVI. The CVI Range can be used to document progress and therefore determine the effectiveness of interventions and further knowledge in the field of evidence-based practices that are appropriate for children with CVI.
