Visual Fields
Vision is often measured by how far down the letter chart we can read correctly. But another very important part of our everyday experience of life is our awareness of the things further out in our peripheral vision: the things we catch a glimpse of “in the corner of our eye”. This wider visual awareness is known as our visual field. Sadly there are some conditions that cause us to lose some or part of our field of vision, the most common of which is Glaucoma.
We have two pieces of high technology equipment to assess Visual Fields.
Zeiss FDT (Frequency-Doubling Technology) is a quick, efficient field screener that assesses the central field of vision and is normally included as part of our standard eye examination on all over-40s.
Humphrey Visual Field Analysis is a more in-depth assessment which we use when there is a history of field loss or when the FDT result indicates further assessment is advisable.
