What is a macular cube?

The macular cube 512 x 128 Combo has 200 horizontal line scans comprising 512 A-scans each. The capture method chosen for the 3-D disc is the macular cube scan, which is able to create a thickness map of the tissue from the ILM to the RPE in the macular area.

What does red on an OCT scan mean?

“Red disease” occurs when an OCT mistakenly identifies an area or eye as abnormal. Here, the thinner RNFL of a high myope doesn’t conform to the limits identified by the normative database and is thus colored red.

Can an OCT scan detect retinal detachment?

An optical coherence tomography scan (OCT scan) is a critical tool for early diagnosis of macular degeneration, glaucoma, retinal detachment, and diabetic retinal disease.

What is normal retinal thickness?

The mean ± SD central foveal thickness was manually measured as 170 ± 18 μm, approximately 12 μm less than the value automatically obtained from the OCT3 software….Table 1.

Region Retinal Thickness in the Healthy Eves, Mean ± SD
Manually determined 170 ± 18
Inner ring (1.5-mm radius)
Superior 255 ± 17
Inferior 260 ±15

Can an OCT scan detect retinal tear?

OCT can detect signs of glaucoma, retinal detachment, macular degeneration, diabetic retinopathy and more at an incredibly early stage.

What is the normal retinal thickness?

Table 1

Automatically determined 182 ±23
Manually determined 170 ± 18
Inner ring (1.5-mm radius)
Superior 255 ± 17

Can OCT scans be wrong?

There are probably dozens of ways in which OCT measurements can be distorted, given the complexity of the technology. However, some artifacts occur more often than others.

What can Oct be used for in optometry?

However, large, multi-centered clinical studies have used OCT in the assessment of macular thickness, and there is extensive literature demonstrating that RNFL and ganglion cell analyses are valuable in the diagnosis and management of glaucoma.

What are the different types of Oct units?

There are currently two distinct OCT technologies commercially available: the older time domain technology and the newer spectral or Fourier domain OCT technology.

What are the different types of OCT scans?

Here’s a how-to on differentiating OCT models and reading their scans. Optical coherence tomography (OCT) has evolved over the last several years from a device used in only a few practices to one found in many primary eye care clinics.

What are the benefits of the new Oct software?

Two more benefits of new OCT software are 3D reconstruction of the retinal image and structural comparison functions, which compare a lesion within an area of the OCT image to the associated location visible on a retinal photograph.
