Courses at the postsecondary level continue to rely heavily on visual material that is accessible only to fully or partially sighted students. Tactile graphics work for many pedagogical purposes, but in some cases are insufficient; other information and concepts may be better conveyed through haptic exploration of 3D printed objects. However,…

Neuro-Ophthalmological Disorders in Cerebral Palsy: Ophthalmological, Oculomotor, and Visual Aspects
Direct linkFazzi, Elisa; Signorini, Sabrina G.; La Piana, Roberta; Bertone, Chiara; Misefari, Walter; Galli, Jessica; Balottin, Umberto; Bianchi, Paolo Emilio – Developmental Medicine & Child Neurology, 2012
Aim: Cerebral visual impairment (CVI) is a disorder caused by damage to the retrogeniculate visual pathways. Cerebral palsy (CP) and CVI share a common origin: 60 to 70% of children with CP also have CVI. We set out to describe visual dysfunction in children with CP. A further aim was to establish whether different types of CP are associated with…

Phenotypical Characteristics of Idiopathic Infantile Nystagmus with and without Mutations in "FRMD7"
Thomas, Shery; Proudlock, Frank A.; Sarvananthan, Nagini; Roberts, Eryl O.; Awan, Musarat; McLean, Rebecca; Surendran, Mylvaganam; Kumar, A. S. Anil; Farooq, Shegufta J.; Degg, Chris; Gale, Richard P.; Reinecke, Robert D.; Woodruff, Geoffrey; Langmann, Andrea; Lindner, Susanne; Jain, Sunila; Tarpey, Patrick; Raymond, F. Lucy; Gottlob, Irene – Brain, 2008
Idiopathic infantile nystagmus (IIN) consists of involuntary oscillations of the eyes. The familial form is most commonly X-linked. We recently found mutations in a novel gene "FRMD7" (Xq26.2), which provided an opportunity to investigate a genetically defined and homogeneous group of patients with nystagmus. We compared clinical features and eye…

Peer reviewedO'Donnell, L. M.; Smith, A. J. – Journal of Visual Impairment and Blindness, 1994
This article describes the physiological mechanisms involved in three-dimensional depth perception and presents a variety of distance and depth cues and strategies for detecting and estimating curbs and steps for individuals with impaired vision. (Author/DB)

Peer reviewedKnoth, Sharon – RE:view, 1995
Students with monocular vision may be in need of special assistance and should be evaluated by a multidisciplinary team to determine whether the visual loss is affecting educational performance. This article discusses the student's eligibility for special services, difficulty in performing depth perception tasks, difficulties in specific classroom…

Groffman, Sidney – 1970
An experimental test of visual closure based on an information-theory concept of perception was devised to test the ability to discriminate visual stimuli with reduced cues. The test is to be administered in a timed individual situation in which the subject is presented with sets of incomplete drawings of simple objects that he is required to name…

Buys, Nicholas; Lopez, Jorge – Journal of Visual Impairment & Blindness, 2004
In-depth interviews with 20 people with monocular vision identified a number of themes associated with the impairment, including psychological, psychosocial, physical, vocational, and daily living problems. They also revealed that in many cases, these problems had profound implications for people's adjustment to daily living. The implications of…
