Wide Field 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.

Wide field retinal imaging.

However optos ultra wide field retinal imaging device achieves ultra widefield photography with a wide field of view of 200 without mydriatic. The ultra widefield retinal image with more than 650 published studies incorporating imaging for diagnosis treatment planning and patient engagement. Wfi refers to imaging beyond 50 degrees field area. 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.

White led 440 650 nm near infrared led 825 870 nm automated stereo imaging of the optic nerve head. 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. Multiple imaging techniques with different light sources. The evolution in retinal imaging.

Uwfi systems can image upto 200 degrees as in optos. 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. 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. 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.

Ultra widefield retinal imaging devices and software. Wide field retinal imaging gives the opportunity to simultaneously visualize the central and peripheral retina in a single session. Notably wide field retinal imaging has taken center stage over the past 2. The other is a new instrument from italy that allows true color retinal imaging.

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. 60 retinal pictures in a single exposure wide field mosaic up to 110 in automatic mode and 150 in manual mode. Imaging modalities and image viewing options are detailed below. Detection management and effective treatment of disorders and diseases evidenced in the retina.

Wide field imaging wfi and ultra wide field imaging uwfi are now increasingly popular.
