CX-1
Digital Retinal Camera
Color
Establishing base Line
Fluo
Checking retinal flow for occlusions and leakage
FAF
Can contribute to the early detection of retinal changes
Red Free
Enhances the visibility of retinal vasculature, hemorrhages, drusen and exudates
Cobalt
Provides a dark background that enhances the visualization of the Nerve Fiber Layer
RGB channels
In addition to the optical filters of the CX-1 , the RX software offers also the possibility of a RGB channel filter. The Red channel can be helpful for the visualization of pigmentary disturbances, choroidal ruptures, nevi and malignant melanomas can contribute to the early detection of retinal changes.
2X magnification
In addition the CX-1 is equipped with a 2X button that provides a 2x digital magnification or depending on a setting, a 30 degrees image.
30 degrees angle
A 30 degrees angle is required for participation in studies and co-operation with most reading centers: i.e DARC, Wisconsin and VRC.
Fundus Autofluorescence (FAF)
A diagnostic technique for documenting the deposition of lipofuscin in the retinal pigment epithelium (RPE). It is easy and non invasive and provides information that may otherwise not be clinically detectable.
It can be a valuable asset in diagnosing retinal disease.
Since the introduction of fluorescein angiography (FFA) in 1959, ophthalmologists observed that even without the use of fluorescein, parts of the fundus would show areas of faint fluorescence under certain conditions. This naturally occurring fluorescence is mainly caused by Lipofuscin. Lipofuscin is a fluorescent pigment that accumulates in the RPE as a metabolic byproduct of cell function.
Lipofuscin deposition normally increases with age, but may also occur from RPE cell dysfunction or an abnormal metabolic load on the RPE. FAF imaging can visualize the deposition of lipofuscin in the retinal pigment epithelium (RPE). Areas of excess Lipofuscin accumulation will appear hyperfluorescent. But when RPE cells die or are absent, LF disappears, leading to hypofluorescence.
Green Spectrum
The CX-1 utilizes green light spectrum to stimulate the retina and captures the emission in the yellow-orange spectrum- utilizing carefully selected matching optical filters. Using the green spectrum may provide more detail in the fovea, as where blue light tends to be absorbed by the high concentration of macular pigments. Additional advantage of green light is that the longer wavelength tends to have less absorption by the crystalline lens of the eye, especially in patients with cataracts.
Am I missing something without FAF?
In this example it is clear that the FAF image is showing additional clinical information that can’t be seen in the color image!
