April is Women’s Eye Health and Safety Month, which may, at first glance, seem a bit of a niche concern. However, according to the organization Prevent Blindness, women make up the majority of the 4.4 million Americans, age 40 and older, who are visually impaired or blind. More women than men have age-related macular degeneration, cataracts, and glaucoma. These numbers will only continue to increase in the years to come.
Although there are no cures for some of these diseases, many of the effects may be lessened through early detection and treatment. A 2015 survey found that one in four women had not received an eye exam in the past two years. Since women may not be aware that they are at greater risk than men of developing eye disease that could lead to serious vision impairment, practitioners can take the opportunity during Women’s Eye Health and Safety Month to stress the importance of paying attention to eye health and the importance of an annual eye exam.
A comprehensive eye exam should include a thorough examination of the retina, including an optomap, which is complementary to a DFE and an excellent tool for screening and for patient education. Because an optomap image …
When Vince Young, OD introduced the Daytona from Optos in his practice, he volunteered to be the imaging guinea pig while his staff was being trained on the device. He was unnerved when he reviewed his images with the trainer and somewhat uncertain about what he was actually seeing. He knew what a posterior subcapsular cataract (PSC) looked like through the slit lamp but was surprised by what the optomap image laid evident. While optomap is known for being able to penetrate through medial opacities far better than white light modalities, a PSC, which tends to be denser than other types of cataract, will cast a shadow on the retina revealing the issue. A concerned Dr. Young sent the image to his wife, Lindsey Brewer Young, OD. When she reviewed the image on her phone she immediately responded, questioning whose eye she was regarding. Learning it was her husband’s image she returned to the clinic, conducted a dilated exam, and confirmed that it was indeed a PSC that had been revealed in the optomap image.
As a private practice optometric physician and professor of optometry near Portland, Oregon, Lorne Yudcovitch, OD had the opportunity to experience optomap technology on a frequent basis for nearly a decade, both in the clinical setting and as a tool for instructing his students. While he valued the ultra-widefield view and the innovative capabilities, he did not purchase an Optos device until 2012.
“I felt that the optomap technology had improved not only in resolution, but it was more user-friendly, making it much easier to position the patient – and we loved the autofluorescence modality. That has become really invaluable.” Yudcovitch explained how optomap Daytona can quickly and easily reveal issues that might otherwise go unnoticed.
He describes a recent scenario when Lila, a 54-year-old Caucasian female, came to the clinic with night vision complaints. Yudcovitch shares that she was correctable to 20/20 vision in each eye and that he found no retinal abnormalities with conventional imaging and ophthalmoscopy. However, the optomap af image revealed significant hyper and hypo fluorescence mottling in the posterior pole in both eyes. Yudcovitch immediately referred her for further retinal examination and genetic testing which revealed a hereditary PRPH2 gene mutation variant.

Getting in early? Join us, Thursday, March 15th at the Lambs Club at 6:30 pm for our Clinical Insights on AMD panel discussion, moderated by Dr. Jeff Gerson, FAAO.
Key topics include: • The epidemiology of AMD and the global burden of the disease • Combining traditional retinal exam methods with new technologies to facilitate early AMD detection • How to customize treatment plans for patients with exudative and non-exudative AMD • Implementing evidence-based nutritional management when appropriate • The roles of macular pigment optical density testing, OCT, and dark adaptometry in building a retina/AMD practice
As an eyecare professional, providing comprehensive exams is tantamount to patient care. By adding tools, such as ultra-widefield (UWF™) retinal imaging with multiple modalities, the ability to detect pathology, which may be missed with single-image modality and/or conventional narrow-field fundus photography, is a game changer.
UWF retinal imaging is performed by a specially designed scanning laser ophthalmoscope (SLO) that generates a high-resolution digital image covering 200 degrees (or about 82 percent) of the retina, in a single capture. By comparison, conventional 7 standard field (7SF) ETDRS and fundus camera photographs produce a relatively narrow view (75 degrees or less) of the retina. The SLO simultaneously scans the retina using two low-power lasers (red – 633 nm and green – 532 nm) that enable high-resolution, color imaging of retinal substructures. The resulting UWF digital image – optomap or optomap af – UWF retinal imaging utilizing fundus autofluorescence (FAF), is produced.
What is Fundus Autofluorescence?
FAF, is an imaging modality used to provide information on the health and function of the retinal pigment epithelium (RPE). Over time, the retinal photoreceptors naturally age and produce a metabolic waste known as lipofuscin. Lipofuscin is the fatty substance found in the retinal pigment epithelium. Excessive amounts can …
