Details

Cerebral Visual Impairment (CVI) is a neurologically based visual disorder which arises from dysfunction or injury involving the visual pathways or cortical visual processing areas (including the occipital, parietal, and temporal lobes). Ocular conditions may co-exist however the primary visual difficulty is exhibited by visual processing dysfunction. Information pertaining to CVI is predominantly directed towards children. However, there is a significant lack of awareness of adults living with paediatric onset CVI. This gap in clinical and habilitation supports to adults subsequently results in many not being able to access their vision to participate in everyday activities. Nevertheless, adults with CVI may be able to also achieve meaningful functional gains through targeted rehabilitation strategies, structured environmental modifications, and multidisciplinary neuro visual intervention. Vision rehabilitation can play a vital role in improving the quality of life in adults with paediatric onset CVI. A range of orthoptic specific intervention can be employed to improve quality of life and participation in daily activities. This case presentation will showcase a 31-year-old female with a diagnosis of Mucolipidosis Type IV (ML4). This is a progressive condition that affects the whole body and presents with neurodevelopmental delay, psychomotor developmental delay and vision loss. Visual processing difficulties were first identified in orthoptic assessments when she was 26 years old. While she presents with numerous typical CVI characteristics, she does not have an official diagnosis of CVI. This client has both ocular and neurological visual impairment including significantly reduced near and distance vision, reduced visual field, oculomotor dysfunction and visual processing difficulties including visual crowding intolerance, visual latency, reduced visual attention and reduced object recognition. This client has received regular fortnightly orthoptic intervention in her home for the last five years. The aim of this presentation is to highlight the instrumental role of regular orthoptic intervention in improving this client’s visual ability to participate in various daily living tasks such as using her vision more consistently during mealtime by recognising her favourite foods and using her vision to make midday snack choices. Furthermore, this client is also more responsive to visually engage in new activities to support her daily activities. She has also recently moved into independent supported living accommodation, and orthoptic services have been instrumental in this life transition. The presentation will also outline improvement in vision including acuity, contrast, fixation, visual response time and visual crowding tolerance. This case aims to illustrate the benefits of regular orthoptic interventions and strategies to support daily activities. Further, the patient outcome demonstrates the pivotal role of low vision management for better quality of life.
