The invention of the scanning laser ophthalmoscope (slo) by webb et. The method is based on the incorporation of a polarimeter into the setup.
The confocal scanning laser ophthalmoscope (cslo) is an instrument that can be used for several retinal imaging modalities including fluorescein angiography, icg angiography and fundus autofluorescence.
Confocal scanning laser ophthalmoscopy. The confocal scanning laser ophthalmoscope (cslo) is an instrument that can be used for several retinal imaging modalities including fluorescein angiography, icg angiography and fundus autofluorescence. [ 1, 2] represented a major advance in ophthalmoscopy. The use of lasers of different wavelengths allows to obtain information about specific tissues and layers due to their reflection and transmission characteristics.
Confocal scanning laser ophthalmoscopy (cslo) is an ophthalmic imaging technology that scans an object point by point by a focused laser beam and then capturing the reflected light through a small aperture (a confocal pinhole). Some manufacturers have modified these instruments so that they are also capable of performing oct. Simultaneous detection of multiple markers was achieved by customising the.
The method is based on the incorporation of a polarimeter into the setup. [3] since the original patent, numerous instruments in many areas of science and engineering have utilized this. The optical system should be designed for diffraction limited performance over the entire field while dm holds flat.
For high resolution retinal imaging, 1 ø1 degree field is used. Adaptive optics confocal scanning laser ophthalmoscope 153 with the speed of scanning mirror (16khz for hs). The source beam aperture at the horizontal scanner is small.
This technique for precise microscopic imaging was patented in 1955 by marvin minsky, now a professor at m.i.t. However, to obtain optimized image quality, one must design the cslo around scanner technology limitations and minimize the effects of ocular aberrations and imaging artifacts. While the instrument provided good enough image quality to measure photoreceptor spacing, it did not have enough contrast to.
The commercial name of the device is heidelberg retina tomograph (hrt). Confocal scanning laser ophthalmoscopy confocal laser ophthalmoscopy (cslo) is the concept behind the heidelberg retinal tomograph. 64 retina today september 2012 developed aspects that helped lead to the creation of the direct ophthalmoscope.
The invention of the scanning laser ophthalmoscope (slo) by webb et. A confocal scanning laser ophthalmoscope with an excitation wavelength of 795 nm was operated both in tight and wide confocal imaging modes. The commercial name of the device is heidelberg retina tomograph (hrt).
Confocal scanning laser ophthalmoscopy figure 1. Some manufacturers have modified these instruments so that they are also capable of performing oct. Hrt ii and hrt iii.
Confocal scanning laser ophthalmoscope (slo). The confocal scanning laser ophthalmoscope (cslo) is an instrument that can be used for several retinal imaging modalities including fluorescein angiography, icg angiography and fundus autofluorescence. Zooming out to a larger field, the system
Two variants are used in current practice: In the confocal scanning laser ophthalmoscope this is accomplished by reusing the source optics for detection. The commercially available scanning laser ophthalmoscope is made by heidelberg engineering, and is called the heidelberg retinal tomography (hrt).
