Toronto—Ultra-widefield retinal imaging enables a comprehensive assessment of retinal pathology, and studies evaluating this technology show that is helping to improve clinical diagnosis and management, said Wai-Ching Lam, MD.
“The ultra-widefield technology provides a high-resolution, nonstered image with up to a 200º field of view that represents 80% of the retina. In addition, the acquisition is non-contact, non-mydriatic, and is very fast, about 0.25 seconds, which makes the procedure very comfortable for patients,” Dr. Lam said. “Furthermore, the digital images are immediately available for review and stored electronically, which is convenient for serial follow-up and telehealth applications.”
The ultra-widefield imaging technology can be used to obtain color images, red-free images, fundus autofluorescence, fluorescein angiography, and indocyanine green (ICG) angiography.
Studies evaluating the images acquired compare favorably with those obtained using standard fundus photography, and because ultra-widefield imaging improves identification of pathology in the peripheral retina, the technique is helpful for imaging eyes with a variety of retinal diseases.
For example, research by Aiello et al. demonstrated the feasibility of ultra-widefield imaging for grading diabetic retinopathy severity. In addition, they also reported that the peripheral retinal lesions visualized using this technology can be a predictor of progression of diabetic retinopathy……
