Optometric practices face growing and more complex patient loads as they support the special needs of an aging population, an increase in diabetic patients and the complications associated with their condition, and manage patient flow so to strike a balance between patient experience and staff productivity. Many optometrists are satisfying all of these demands by incorporating ultra-widefield (UWF™) retinal imaging into their practices.
About Ultra-Widefield Retinal Imaging
UWF retinal imaging is performed by a specially designed, table-top scanning laser ophthalmoscope (SLO) that generates a high-resolution digital image covering 200° (or about 82%) of the retina. (this compares to other imaging techniques with fields of view typically under 45°).
The SLO simultaneously scans the retina using two low-power lasers (red and green) that enable high-resolution, color imaging of retinal substructures. The resulting UWF high resolution digital image – the optomap – is produced in a single capture without pupil dilation. Tabletop systems designed for optometric practice (Daytona) provide both UWF color imaging and UWF autofluorescence modalities in a single scan.
Unlike routine slit lamp examinations, optomap can be performed by a trained technician. The image is captured in less than a second using automatic prompts that position the patient for an accurately. …
The need to increase the rate and accessibility of ocular health screenings is significant. For example, of the 415 million adults worldwide who are afflicted with diabetes, 45 percent are undiagnosed. A large percentage of these undiagnosed individuals will develop diabetic retinopathy (DR) and DME diabetic macular edema (DME). Also important is the diagnosis of other conditions, many of which are found in aging populations, including age-related macular edema (AMD), branch retinal vein occlusion, glaucoma, and cataracts.
One way to widen the availability of ocular health screenings is through telehealth and telemedicine programs. These initiatives are growing worldwide as stakeholders in the health community take advantage of advances in medical and communications technology. One such innovation with particular utility in ocular telehealth is ultra-widefield (UWF™) retinal imaging, which offers an effective, rapid, and easy-to-use means bringing state-of-the-art diagnostics to underserved populations. This technology, developed by Optos, has been deployed in a variety of telehealth settings.
