A 2-year-old child with cerebral visual impairment (CVI) was brought by the mother to the pediatric ophthalmology clinic. She underwent a detailed functional vision and developmental assessment that revealed impairments in visual developmental skills, sensory, motor, and social skills. She was admitted into an integrated, parent-centered, structured early intervention program specifically designed for her for 3-months after which there were improvements noticed in visual developmental skills such as visual fixation, attention, and tracking; sensory skills such as tactile, olfactory, and gustatory; motor skills, including neck control and fine motor grasping; and age-appropriate social and communication skills. Through this case report, we aim to bring out the benefits of an evidence-based systematic early intervention approach in a child with CVI.

Cerebral visual impairment (CVI) is increasing in prevalence in developing countries, necessitating early diagnosis and habilitation in an integrated approach to promote the wellbeing of the child and the family. In India, the gap in the current evidence includes a lack of standardized evidence-based early intervention approaches. This case report of a child with CVI who was provided early intervention in a customized manner depicts the planning, execution, and its benefits.
| Case Report|| |
A 2-year-old female was brought to the pediatric ophthalmology clinic by the mother with visual concerns noticed since birth. The child was born full-term by vacuum delivery with a birth weight of 2.8 kg. After 10 days from birth, the absence of body movements and cry were observed by the parents. She was admitted to the neonatal intensive care unit for the same and was diagnosed to have seizure disorder for which she was under medication for a few months after birth. She was diagnosed to have neonatal encephalopathy and microcephaly leading to global developmental delay by the neurologist. Her magnetic resonance imaging report showed extensive laminar cortical necrosis in the bilateral cerebral hemispheres and brainstem, and cephalohematoma in the left parietal convexity.
Baseline visual function and functional vision assessment
Comprehensive eye examination revealed insignificant refractive error, normal ocular alignment, and anterior and posterior segment evaluation. The functional vision assessment (FVA) carried out by a pediatric optometrist was based on the literature established by Hyvärinen et al. and Swaminathan et al. [Table 1]. FVA explains the use of visual functions in performing daily activities.
The study was approved by the Institutional Review Board of Medical Research Foundation, Chennai, and adhered to the declaration of Helsinki. An informed consent form was obtained from the mother before the intervention phase. The goals of early intervention were to help the child to learn to use her vision and achieve a holistic improvement.
Individualized program planning (IPP)
After assessing the other developmental areas of the child, the vision rehabilitation and early intervention specialist conducted 3 months (34 sessions, 1 hour each) of in-office habilitation followed by daily home-based habilitation, which was managed by the mother trained by the rehabilitation professional. The child underwent neuro-developmental and occupational therapy twice a week. She was also referred to a pediatric neurologist. The habilitation was based on the concepts proposed by Pletcher and Younggren., The sequence of the therapy is illustrated in [Figure 1].
Along with the existing protocol in place, the early intervention approaches [Figure 2] were adapted and modified from the early support developmental journal by Dale et al.; they were (i) visual developmental therapy, which included training visual: tracking, attention, robustness, and fixation; (ii) sensory integration therapy, including stimulation and integration of all senses; (iii) movement and mobility, including gross and fine motor training; (iv) development of age-appropriate social, communication, and language skills; and (v) independent self-care. After the completion of each session, the (i) skills trained (ii) activities performed, and (iii) specific observations were documented. The rooms that were used were kept clutter-free and noise-free.
Outcomes and follow-up
After the habilitation period, improvements were noticed in the overall development of the child [Table 2].

Due to the COVID-19 pandemic regulations and for safety precautions, an in-person follow-up was restricted; instead, a telephonic interview was opted to understand the child's progress. Currently, the child is continuing home-based habilitation and will be starting the next phase of visual skills training. She is in constant care of the neurologist, shows resolved seizures, and is on telephonic follow-up with the rehabilitation specialists and the team. The next step in intervention would be visual skills training, which would include visuomotor integration, visual perceptual skills, and concept development for preschool preparation.
| Discussion|| |
The visual cortex is highly plastic to the experiences during post-natal development, and it is important to utilize this sensitive time to intervene in CVI, which has been done in this case. The early intervention approach adopted in this case was based on two well-established studies: (1) the five foundational concepts proposed by Pletcher and Younggren which includes family-centered practice, natural environment, child and adult learning, and quality team practice;, and (2) the structured, five-themed developmental framework described by Dale et al. in their paper. We strongly believe that basing our approach on prior evidence by following a systematic, parent-centered protocol involving integrated team practice customized to the needs of the family was the contributing factor to the improvements noticed in the child, and we recommend experts to follow such an approach while intervening children with CVI.
Though we noticed functional improvements in the child, there is a possibility of natural development to have contributed to this, and with a lesser follow-up duration and absence of control, these outcomes cannot be based entirely on the intervention provided. To combat this limitation, we recommend a longitudinal study with a control group and a large sample size. Despite the availability of literature involving early intervention globally,,,, there is paucity in evidence-based approaches to early intervention in India.
| Conclusion|| |
Considering the importance of habilitation in CVI, this case report serves as a good starting point, depicting the planning and execution of early intervention thereby creating awareness among CVI experts in India to explore this area for more promising studies.
