The visual field is all the space that an individual can see at a point in time. Perimetry is the measurement of the visual field. Standard techniques involve either moving a white light stimulus presented against a uniformly white background from an area of non-seeing until it is seen by the observer (kinetic perimetry) or gradually increasing the intensity of a white light stimulus at a fixed point in the visual field until it is seen by the observer (static perimetry). Non-standard techniques involve using stimuli which are tuned to specific channels in the visual system. This selective sampling enables abnormalities of the visual field to be detected at an earlier stage than can be accomplished using standard perimetry.
My research takes place within the Ophthalmic Research Group and primarily concentrates on statistical analysis of visual field data and examination of structure-function relationships in central retinal eye disease and in autism. Perimetry methodologies currently being investigated are standard perimetry, short-wavelength automated perimetry (SWAP), flicker perimetry, frequency doubling technology (FDT) and microperimetry. I am also applying perimetry methodologies to multi-focal electroretinography (mERG) which is an objective visual field examination.
1. Application of SWAP to the central 10-degree visual field (Cubbidge et al 2002).
2. SWAP reveals defects with no other clinical signs (Cubbidge et al 2002) and may have diagnostic utility in age-related maculopathies.
1. SWAP reveals central visual field damage not previously documented (Hilton, Cubbidge, Hosking et al 2002).
I am also investigating visual function in autistic spectrum disorders in terms of non-standard visual field methodologies and in electrophysiological and optical methods of assessing eye movements. I also have research interests in biometry applications for measuring the visual space projection on the retina and in various topics in ophthalmic lenses and ophthalmic dispensing.
