Research summary
Many children with neurological disabilities have impaired vision. As most vision tests require co-operation from the child, it is currently difficult to obtain a measurement or even an estimate of their visual function. This is particularly true for tests of the peripheral visual field, which is essential for locating objects and navigating in space.
Parents and carers are often anxious to know how much their child can see. As vision develops and matures after birth and requires stimulation and feedback, it is desirable to know the extent of the child’s vision, to provide optimal support and stimulation.
As a formal assessment of visual fields is usually not possible in young children or those with neuro-disabilities, children may miss out on the benefits of being registered.
A new visual field test (saccadic vector optokinetic perimetry, SVOP) may be more accessible for children than current visual field tests (VFT). The overall aim of the proposed study is to gather data supporting rationale, feasibility and methods for a subsequent diagnostic test accuracy study comparing the new SVOP with the current clinical standard (Goldmann visual field test, GVFT).We propose to carry out an exploratory observational study with two study groups: A) children age 1 to 16 years with neurodisability attending Great Ormond Street Hospital (GOSH), Moorfields Eye Hospital (MEH), or the Child Development Centre in Bedford (CDCB) and unable to co-operate with current visual field tests; B) children age 10 to 16 years with confirmed or suspected visual field defect attending GOSH or MEH and able to co-operate with Goldmann visual field testing. Data from group B will be used for an exploratory observational method comparison study of SVOP and GVFT.
