The FDT, or Frequency Doubling Technology, is a visual field testing method that is particularly effective in detecting early visual field defects associated with various ocular diseases. This technology is particularly sensitive to changes in the visual system and can help identify issues related to the retina, optic nerve, and the visual pathways to the brain.

When it comes to the retina, the FDT can detect abnormalities that may be caused by conditions such as glaucoma, which can lead to damage of the retinal nerve fibers. Furthermore, since glaucoma primarily affects the optic nerve, the FDT is also instrumental in evaluating the integrity and functioning of this nerve.

Additionally, the FDT assesses the visual pathways that extend to the brain, providing insight into how visual information is processed. By testing for peripheral vision loss, which may indicate problems along these pathways, practitioners gain comprehensive insights into a patient's visual health.

Therefore, the capability of the FDT to detect various diseases and disorders affecting these critical components of the visual system supports the conclusion that it is effective in revealing issues across the retina, optic nerve, and visual pathways, making the statement "All of the above" accurate in the context of its diagnostic applications.
