Eye Assessors

What is a clinical and function vision assessment for low vision bioptic driving?

(Note: These parameters are consistent with the International Council of Ophthalmology (ICO) 2006 Visual Standards report "Visual Requirements for Driving Safely" - see their report on recommendations for assessing functional vision):

  • Visual acuity better than 6/60

  • Visual acuity through the scope 6/12 or better

  • No more than 3 scotomas in the visual field

  • Vertical 110 and Harizonal 120 visual periphery

  • Can differentiate colour (can still be colour blind or deficient)

  • Contrast sensitivity that is at least age matched

  • Able to demonstrate glare recovery

  • A stable eye condition (no major variations)

  • If progressive, is regularly monitored

An optometrist can work with an orientation and mobility (O&M) specialist. After the above assessment the O&M can conduct static and dynamic in room and outdoor on foot and passenger in car assessments. These assessments contribute to understanding the candidates visual processing.

 

As an example to see how the above is done in practice with both the optometrist and O&M see Churchill Fellowship blog "17. Bioptic driving in The Netherlands and the Europrean Union".
