The Retina01:32

The Retina

71.0K
The retina is a layer of nervous tissue at the back of the eye that transduces light into neural signals. This process, called phototransduction, is carried out by rod and cone photoreceptor cells in the back of the retina.

Anatomy of the Eyeball

7.7K
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle...

Vision01:24

Vision

55.8K
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Visual System01:26

Visual System

781
Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

Area of Science:

  • Ophthalmology
  • Medical Imaging
  • Artificial Intelligence

Background:

  • Current retinal function tests are subjective, non-localized, and burdensome for patients.
  • Objective and automated methods are needed to assess retinal sensitivity.

Purpose of the Study:

  • To develop and evaluate a deep learning (DL) algorithm for predicting retinal sensitivity from structural Optical Coherence Tomography (OCT) images.
  • To establish OCT imaging as a surrogate for visual function assessment.

Main Methods:

  • A DL algorithm was trained and validated on 714 OCT volumes from 289 patients with various retinal conditions.
  • The algorithm predicted retinal sensitivity maps from OCT scans, with performance evaluated against microperimetry data.
  • External validation was performed on diverse patient cohorts, including those with diabetic macular edema and retinal vein occlusion.

Main Results:

  • The DL algorithm achieved a mean absolute error (MAE) of 2.34 dB for point-wise sensitivity (PWS) and 1.30 dB for mean sensitivity (MS).
  • Correlation coefficients demonstrated strong agreement between predicted and measured retinal sensitivity (Pearson: 0.66-0.84, Spearman: 0.68-0.83).
  • External validation confirmed the algorithm's efficacy with an MAE of 2.73 dB for PWS and 1.66 dB for MS.

Conclusions:

  • Deep learning analysis of OCT scans can accurately predict retinal sensitivity, serving as a structural surrogate for visual function.
  • This approach offers potential for improved disease progression monitoring and objective outcome measures in clinical trials.
