  • Principle of Optical Coherence Tomography (OCT) are based on the principle of low coherence interferometry. Interferometry is a method to measure the phenomenon of superimposing waves usually light, sound and radio waves in order to detect the differences occurs between them. 
  • Interferometry works because of two waves that have the same frequency and same phase will add each other while the two waves with opposite phase will substract.  
  • A light source is composed of a range of wavelengths with a broad spectral bandwidth. In such a broadband source has low coherence, while monochromatic laser light has a narrow spectral line and features a coherence length of at least several meters. 
  • Light that coming from a source will separate into two separate paths and combines the light coming back from the two paths at the interferometer output. 
  • Under certain conditions, interference can be noticed. The coherent waves superimpose and their electromagnetic field amplitudes add constructively when they reinforce each or destructively if they cancel out each other) or meet any condition in between.

    2) Thickness of retina can be measured and layers within retina can be differentiated.

    3) Early detection and diagnosis of retinal diseases and conditions.

    4) Some examples of eye conditions can be diagnosed using OCT:
    • age-related macular degeneration
    • glaucoma
    • central serous retinopathy
    • diabetic retinopathy
    • vitreous traction

    5) Examples of examination can be conducted using Cirrus HD OCT:
    • Pachymetry (measures thickness of corneal)
    • HD corneal imaging
    • Epithelial thickness mapping (thinning may reveal early signs of keratoconus)

Cirrus 6000 operates at an A-scan acquisition rate of 100 kHz whereas Cirrus 5000 has an A-scan acquisition rate of 27 kHz. The corneal motion correction algorithm (IITE 2017 – Bagherinia et al., “A self-correcting method to reduce motion artifacts in OCT corneal scans”) was applied to each scan. The algorithm outputs the x, y and z motions of each radial B-scan of a pachymetry scan pattern (24 radial B-scans over 9 mm diameter with 1024 samples; 24 x, y and z shift parameters). These parameters are obtained by minimizing error between the anterior corneal surface of OCT data and the two dimensional parametric model (e.g. quadric surface) of the corneal surface at each iteration. The almost circular projection of corneal surface contour lines on the xy-plane (see Figure 1, right) show that the motion artifacts from the unprocessed image (see Figure 1, left) were reduced by the algorithm. The standard deviation (SD) of the x, y and z shift parameters is used to determine the overall eye motion in each scan.

    Results : The comparison of the SD values for x, y and z shifts between the two systems show that the higher acquisition speed of Cirrus 6000 results in a significant reduction of motion/shift (see Table 1) while scanning (38% x-direction, 49% y-direction, 42% z-direction). Overall, the motion artifacts of faster scan acquisition are less than for slower scan acquisition.

    Conclusions : Due to a faster scan rate the eye movement during an image acquisition is naturally less. This ultimately enhances the scan quality by reducing the impact of motion artifacts.
