Evaluation of Vision Behaviors in Children with Cortical Visual Impairment Due to Cerebral Palsy (CP)

Abstract

Background and Objective: Cortical Vision Impairment in children is one of the visual disturbances which are occurring due to brain disorders. There are not eye disorders as usual. It has been shown that the image processing in the brain has been affected. Among brain disorders, cerebral palsy (CP) is one of those disorders that leads to at least two third of cortical blindness among these patients. Observation of the vision behaviors is an appropriate way to evaluate the amount of vision as well as provide low vision rehabilitation. Method: vision behaviors were evaluated by interview with parents of children under 15 years old. Consent was achieved before interview and participants were informed well about the process. Attendance of one of parents was enough to run the interview preferably mother. Semi-structured individual interview was used to discover vision behaviors of children in daily life. The interview was recorded then transcribed verbatim into text word for thematic analysis. Results: 22 parents of 18 children with CP participated in this study. (Mean age 37.4±2.51). Parents did not have enough information to deal with their children. They needed special education. Rehabilitation programs from occupational therapists were very effective. The most effective one was physical rehabilitation. There are very significant behaviors which were common among children. This behavior is not being observed among visually impaired children with ocular causes. Conclusion: Parents do not have much concern about vision of their children. They believe physical rehabilitation is much important than vision rehabilitation. Parents need more education to participate in rehabilitation programs for these children.

Validation of the Functional Vision Evaluation for Children (FVEC) battery

“…and Dundon, Bertini, Ladavas, Sabel & Gall (2015) have represented this great concern in visual rehabilitation, pointing to the need to evaluate themselves in an appropriate and integrative way, seeking elements that allow clarity for the therapeutic decision of restorative or compensatory treatment. Our evaluation battery, allowing the identi cation of local and global losses, presents itself as a robust alternative to support this decision of fundamental Braddick, 2012) and behavioral measures that can help understand the functional use of vision(Riazi, 2018). Assessment methods for children with low vision, especially with cortical visual impairment, aiming to improving the quality of measures of basic visual functions such as visual acuity, and even behavioral measures that can help understand the functional use of vision.…”
