Identifying a need for additional care

People with visual problems do not always receive the additional care they need, because their complaints are not recognized in time. Additional care, such as (neuro)visual rehabilitation, helps people with visual problems to maintain their independence and quality of life. However, many people access this care at a late stage or not at all. This applies to individuals with eye diseases as well as those with acquired brain injury (ABI). In her PhD research, Vera Linde Dol developed two screening questionnaires to improve earlier detection.

The VQL-6 (6-item Vision-related Quality of Life and Limitations questionnaire) comprises of six questions that provide insight into the patient’s quality of life and perceived visual limitations in ophthalmic practice. The outcome of the questionnaire is visible in the electronic medical records and helps ophthalmologists to identify who may benefit from additional care. A pilot study at the UMCG showed the VQL-6 could facilitate timely referrals and was positively received by both patients and ophthalmologists.

For neurorehabilitation, the SVCq-ABI (Screening Visual Complaints questionnaire – Acquired Brain Injury) was developed. This 23-item questionnaire identifies visual complaints in people with ABI, such as blurry vision, light sensitivity, and reading difficulties. The results showed that 78% of individuals with ABI reported one or more visual complaints, highlighting the importance of systematic screening.

Both questionnaires are practical in use, easily integrated into digital patient systems, and align with the trend towards patient-centered care. They support healthcare professionals in recognizing a potential need for additional care at an earlier stage, thereby supporting the deployment of timely, appropriate care for people with visual problems.
