Visual Field Index

The Visual Field Index (VFI) is a measurement used by eye doctors to assess how well your peripheral and central vision are functioning. It provides a percentage score, where 100% means normal vision and 0% indicates complete loss. The VFI helps track the progression of eye conditions like glaucoma by showing changes over time. It is derived from your visual field tests, which map out areas where you can see. Overall, the VFI offers a helpful, easy-to-understand snapshot of your visual health, guiding treatment decisions and monitoring disease stability or progression.
