“…However, gain in children with visual impairments may follow different maturation pathways. Importantly, pursuit can be improved by training (Salati et al 2002;Coetzee & Pienaar 2013). Gain might improve when children learn to compensate for pursuit impairments, e.g.…”

“…As a consequence, impairments in oculomotor behaviour can have a detrimental effect on vision (Hyv€ arinen 2010). In recognition of a close relationship between oculomotor dysfunction and visual impairments (Salati et al 2002), visual and oculomotor training and visual rehabilitation tools are increasingly available for visually impaired children (Trauzettel-Klosinski 2011;Coetzee & Pienaar 2013). The sooner oculomotor and visual problems are detected, the sooner intervention can start to provide better opportunities when children reach school age.…”

“…[ 17 ] Coordination disorder is defined as any problem or limitation in motor coordination, resulting in a lower than expected performance, depending on the patient's chronological age. [ 18 ] Improvement of eye–hand coordination as a perceptual-motor skill depends on the visual system as well as efficient eye muscle control. [ 19 ] Vision therapy is recognized as an individualized intervention to improve the binocular system, ocular motor control, visual processing, visual motor skills, and perceptual or cognitive deficiencies.…”

[ 18 ] According to several studies, vision therapy could improve binocular skills, ocular motor control, visual attention, visual perception, and visual processing skills. [ 20 21 22 23 24 ] Since the first essential stage of normal eye–hand coordination is the visual detection of the target, reduced visual acuity could affect stereo-acuity and eye–hand coordination.…”

Purpose:To evaluate the enhancing effects of vision therapy on eye–hand coordination skills in students with visual impairments.Methods:Thirty-five visually impaired patients who underwent vision therapy comprised the treatment group, and 35 patients with impaired vision who received no treatment comprised the control group. Full ophthalmic examinations were performed, including biomicroscopy, retinoscopy, and assessments of subjective refraction and visual acuity. Eye–hand coordination was evaluated using the Frostig test. Vision therapy in the treatment group was performed using the Bernell–Marsden ball, perceptual-motor pen, random blink test, and random shape assessment.Results:Data were analyzed for the 35 visually impaired patients and 35 control participants. The mean age was 11.51 ± 3.5 and 11.09 ± 3.1 years in the treatment and control groups, respectively. Female participants comprised 80% of the treatment group and 57% of the control group. Before treatment, the mean scores on the Frostig test were 22.74 ± 4.32 and 21.60 ± 4.10 in the treatment and control groups, respectively, and after treatment, the mean Frostig test scores were 24.69 ± 3.99 and 21.89 ± 3.92, respectively. Statistically significant intergroup differences were found in eye–hand coordination (P < 0.05). No significant intergroup differences were noted in the distance and near visual acuity values.Conclusion:The results demonstrated that vision therapy could significantly improve eye–hand coordination, but no enhancement was found in near or distance visual acuity.

“…The development and improvement of perceptual and motor skills such as spatial orientation, coordination (hand–eye, foot–eye, hand–foot–eye coordination), balance, and body awareness are dependent on an effective visual system as well as good eye muscle control ( Willoughby and Polatajko, 1995 ; Cheatum and Hammond, 2000 ; Coetzee and Pienaar, 2013 ). In this way, if there is any defective input of information by way of the visual system, the reaction of the motor output to such information will also be defective, leading to visuo-motor or motor deficiencies and poor concentration ( Peens and Pienaar, 2007 ; Coetzee and Pienaar, 2013 ).…”

Cerebral visual impairment (CVI) has become the primary cause of visual impairment and blindness in children in industrialized countries. Its prevalence has increased sharply, due to increased survival rates of children who sustain severe neurological conditions during the perinatal period. Improved diagnosis has probably contributed to this increase. As in adults, the nature and severity of CVI in children relate to the cause, location and extent of damage to the brain. In the present paper, we define CVI and how this impacts on visual function. We then define developmental coordination disorder (DCD) and discuss the link between CVI and DCD. The neuroanatomical correlates and aetiologies of DCD are also presented in relationship with CVI as well as the consequences of perinatal asphyxia (PA) and preterm birth on the occurrence and nature of DCD and CVI. This paper underlines why there are both clinical and theoretical reasons to disentangle CVI and DCD, and to categorize the features with more precision. In order to offer the most appropriate rehabilitation, we propose a systematic and rapid evaluation of visual function in at-risk children who have survived preterm birth or PA whether or not they have been diagnosed with cerebral palsy or DCD.
