Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Area of Science:

  • Ophthalmology
  • Medical Imaging
  • Artificial Intelligence

Background:

  • Accurate visual field (VF) testing is crucial for diagnosing and monitoring glaucoma.
  • Standard 24-2 VF tests may not capture subtle paracentral vision loss characteristic of early glaucoma.
  • 10-2 VF tests provide higher resolution in the central visual field but are more time-consuming.

Purpose of the Study:

  • To develop and validate a deep learning model for predicting 10-2 visual fields (VFs) from standard 24-2 VFs.
  • To assess the model's ability to incorporate non-total deviation features for improved prediction accuracy.
  • To evaluate if predicted 10-2 VFs enhance the understanding of the structure-function relationship in glaucoma.

Main Methods:

  • A transformer-based deep learning model was developed using 5189 pairs of 24-2 and 10-2 VFs from 2236 patients.
  • The model utilized 52 total deviation values and nine VF test features to predict 68 10-2 total deviation values.
  • Performance was evaluated using mean absolute error, root mean square error, and R2; structure-function relationships were analyzed.

Main Results:

  • The model achieved an average mean absolute error of 3.30 ± 0.52 dB and an R2 of 0.70 ± 0.11 for 10-2 VF prediction.
  • Incorporating nine VF test features improved prediction accuracy, with age identified as a key parameter.
  • Predicted 10-2 VFs significantly improved the structure-function relationship between macular thinning and paracentral VF loss (P < 0.001).

Conclusions:

  • Deep learning models can effectively predict 10-2 visual fields from 24-2 visual field data.
  • The inclusion of additional VF test features enhances prediction accuracy.
  • Predicted 10-2 VFs show promise for improving glaucoma diagnosis and patient management.
