Details |
Comparator Agent |
control |
standard therapy which will include pediatric and ophthalmological evaluation and management of childs systemic conditions, dispensing spectacles (if indicated) |
Intervention |
Visual Therapy (visual stimulation, visuomotor and visuoperceptual learning interventions) |
Intervention- a structured training
Various visual stimulation exercises will be explained at baseline and every follow up; additionally, educational videos will be shared for other caregivers at home not visiting
It will be dividd into three parts:
1) Building visual behabiour like visual attention (VS) excercise using bright colour simple toys without simple array, using tactile stimulation, movement,light in decluttered environment and opto-type presented one at a time multiple times in a day coherent with attention span of child simple target one at a time, also passive checkerboard or sine wave grating pattern or alternating checker board pattern with odd ball stimuli
2) Building and integrating attention with visual function (visual motor and visual perception) (VS + VML + initiate basic VPL exercise) using visual communication, follow, fixation, reaching out, hand eye coordination, visual search, visual recognition.
3) Further Building and refining VML + VPL and build cognition like expanding items of visual recognition, facial recognition, copying, figure ground, form constancy, short term visual memory, tasks in visual clutter, task involving distance vision, visual memory, tasks requiring planning.
Frequency and dose of advised visual exercises: 10-15 minutes every waking hour of child preferably total of 3-4 hours/day
Duration of intervention: 1 year |

Brief Summary
|
This study aims to study rehabilitative effectiveness of vision therapy in improving visual attention, visuo-perceptual, visuo-motor and visuo-cogntive behaviour in children with cerebral visual impairment by conducting a randomised controversy study where patients will be divided into two arms: one arm shall receive standard therapy and other would receive vision therapy apart from standard management. Vision therapy will include home based tailored visual stimulation, visuo-motor, visuo-perceptual and cognitive tasks depending on child’s functional vision. Children with suspected CVI will be observed and proforma will be filled up with regard to their neuro-visual behaviours, characteristic findings, visual grade, oculomotility pattern, electrophysiological tests, fundus findings, imaging findings etc. All children will undergo detailed paediatric neurological evaluation. Imaging will be analysed by radiologists and scored. The rationale of the study is that home-based visual stimulation and rehabilitative strategies (tailored to the CVI inventory responses and examination findings) if explained to carers and carefully applied, can improve visual skills and neuro-visual behavior in children with cerebral visual impairment, thereby improving everyday visual functioning, participation, and quality of life as an ultimate goal. |
