Wide Field Retinal Imaging

The advent of widefield retinal imaging has shown us that indications of disease are often located in the far periphery of the retina clarus 500 is the next generation fundus imaging system from zeiss that provides true color and high resolution across an entire ultra widefield image.

Wide field retinal imaging.

White led 440 650 nm near infrared led 825 870 nm automated stereo imaging of the optic nerve head. However optos ultra wide field retinal imaging device achieves ultra widefield photography with a wide field of view of 200 without mydriatic. Older wide field retinal imaging systems had significant downsides such as the requirement of a contact lens and a clear ocular media acquiring images from the far peripheral retina was difficult requiring a skilled technician and demanded difficult tasks from. Notably wide field retinal imaging has taken center stage over the past 2.

The evolution in retinal imaging. Ultra widefield retinal imaging devices and software. Diabetic retinopathy can be diagnosed and graded with the use of a newer scanning technology called ultra wide field uwf imaging a system that generates high quality pictures showing most of. Wide field retinal imaging gives the opportunity to simultaneously visualize the central and peripheral retina in a single session.

Detection management and effective treatment of disorders and diseases evidenced in the retina. The other is a new instrument from italy that allows true color retinal imaging. In the past six months two new instruments designed to provide high resolution views of the retina have been approved by the food and drug administration one is the latest iteration of optos s wide field scanning devices. The only ultra widefield retinal imaging device with integrated uwf guided swept source oct silverstone produces a 200 single capture optomap image in less than second and enables guided oct scanning across the retina and into the far periphery.

Imaging modalities and image viewing options are detailed below. See how you can reveal more with clarus 500 the newest retinal camera from zeiss. Retinal imaging serves as a critical adjunct to the diagnosis monitoring and treatment of numerous ocular diseases. Since the invention of the direct ophthalmoscope by hermann von helmholtz in 1851 techniques to visualize the fundus have grown exponentially both in number and sophistication.

Wfi refers to imaging beyond 50 degrees field area. Retinal imaging techniques have evolved at a remarkable pace in the last two decades. This is realized by a unique optical system utilizing an ellipsoidal mirror which has a concave three dimensional shape and laser light that scans the retina. Uwfi systems can image upto 200 degrees as in optos.

Multiple imaging techniques with different light sources.
