My initial interest in the optical designs of invertebrate eyes led me to examine how visual systems squeeze real-time visual information into brains of very limited information capacity. My subsequent research into adaptive neural processing has lead to new glaucoma detection devices, the FDT and Matrix Perimeters, now being marketed by Carl Zeiss Meditec. Drs Corinne Carle and Josh van Kleef and I are now extending that work to provide objective non-contact perimetry using multifocal pupillography. The platform is now called the objectiveFIELD and is being developed with Konan Medical USA, we are being assisted by Dr Faran Sabeti of the School of Optometry and Visual Sciences at the University of Canberra. The objectiveFIELD has been shown to have value in Glaucoma, Diabetic Retinopathy, Macular Degeneration and Multiple Sclerosis. Other recent work includes the adaptive dynamics of following eye movements; the processing of texture, and brightness; and methods for diagnosing neurological disorders.
