What is normal macular thickness on OCT?
Results. Foveal thickness (mean thickness in the central 1000-μm diameter area) and central foveal thickness (mean thickness at the point of intersection of 6 radial scans) on the OCT3 were 212 ± 20 and 182 ± 23 μm, respectively.
What should retinal thickness be?
The retina was thickest in the inner circle (mean 334.5 μm, median 334.8 μm) and thinnest in the center subfield (285.4 μm, median 285.0 μm). Retinal thickness was most variable in the center subfield (SD 22.3 μm, range 172–368.0 μm) and least variable in the outer circle (SD 13.6 μm, range 238.0–331.0 μm).
What is a normal macular thickness?
Foveal thickness in males was measured to be 232.68±21.07 µm, while in females it was 222.87±18.72 µm (p<0.0001). Mean macular thickness in males was 266±14.20 µm, while in females it was 258.21±10.03 µm (p<0.0001)….Table 1.

What is normal central subfield thickness?
On average, central subfield thickness was 201 ± 22 microns. Central subfield thickness was significantly greater in retinas from men than retinas from women subjects (mean 209 ± 18 microns versus 194 ± 23 microns, P<0.001).
How can I improve my retina thickness?
How to Improve the Health of the Retina
- Healthy and balanced diet.
- Avoiding unhealthy foods and drinks.
- Drinking plenty of water.
- Regular exercise.
- Wearing sunglass when out in the sun.
- Quitting smoking.
- Wearing eye protection.
- Regular eye check-up.
How do you read an October?
Interpretation of the OCT image requires understanding that the image was based on light waves. Thus, the image is subject to the characteristics of light waves, and one can see reflections, attenuations, interfaces, and shadows in the image due to this property of light.
What do the colors on a retinal thickness MAP Mean?
In general, all machines have a thickness map displaying the average retinal thickness values in 1 mm, 3 mm, and 6 mm diameter circles divided into sectors with color map. Warm colors indicate thicker retinal areas and cool colors indicate thinner retinal areas [ Fig. 7 ].
How is the retinal thickness deviation map generated on an Oct scan?
The 12 × 9-mm 2 macular volume SS OCT scan was performed, and the retinal thickness deviation map was generated automatically using the built-in software. On this map, yellow (retinal thickness, <5% of the normative level) or red (<1% of the normative level) pixels were defined as abnormal.
Can we measure normal macular thickness using OCT mapping software?
Objective To report normal macular thickness measurements in healthy eyes using the latest commercially available optical coherence tomography (OCT) mapping software, version 3.0, from the Stratus OCT (OCT3). Methods Thirty-seven eyes from 37 healthy subjects underwent a complete ophthalmologic examination, including OCT.
What do the colors on the Oct scan map mean?
Thousands of points are measured in a single OCT scan and these are plotted on a map using colors to represent thickness value. Warm colors, such as red and white, are relatively thicker areas of the RNFL, while cooler colors, such as green and blue represent relatively thinner areas of the RNFL.
