The Retina – A Window to Alzheimer’s Disease

In a novel study from Queen’s University Belfast, researchers demonstrate that the eye could be a window to the brain. The results of the study, recently published in the Journal of Ophthalmic Research, show how degenerative brain diseases such as Alzheimer’s Disease (AD) can be monitored via ultra-widefield (UWF) retinal imaging.  The retina is a part of the central nervous system and shares structural and functional features with the brain. Altogether 59 AD patients and 48 controls were entered into the study.  They were imaged utilizing ultra-widefield imaging from Optos.  This advanced technology, using red and green lasers, captures a 200 degree, high-resolution digital image of the retina in less than ½  second, reaching regions of the retina that have been previously inaccessible with other methods of imaging.

Measuring biomarkers, such as drusen and vasculature width gradients in delineated quadrants of the retina, the researchers found that these changes, particularly in the peripheral retina, could be associated with degenerative brain conditions such as AD. Specifically, the markers that were chiefly considered were drusen and vasculature changes. Drusen are deposits of fats, minerals, and proteins and are normal symptoms of aging that appear as yellowish spots in the layer beneath the retina.  While they are harmless and typically begin to appear after the age of 40, an increased occurrence in number and size can contribute to the degeneration of the retina.  In the study, at baseline and follow up, the optomap images revealed that drusen accumulation, particularly in the superior nasal quadrant, were increased and significantly associated with positive AD status as compared to the number of drusen that would be normally expected in the control group. An additional novel element of the study was that by utilizing the UWF view of optomap, the width gradient of the vasculature could be observed in entirety from the macula to the far retinal periphery.  The study found that people with AD have blood vessels that are wider closer to the macula and thin as they progress further into the periphery.  This can impede the flow of blood and the essential delivery of nutrients and oxygen in the periphery, leading to further damage.

The team, led by Dr. Imre Lengyel of Queen’s University, hypothesized that changes in the peripheral retina could be important to explore the association between the eye and the brain. They concluded that their research supported their original hypothesis and that UWF retinal imaging has significant potential for monitoring AD and other degenerative brain diseases via the eye.  Utilizing optomap to evaluate progression of AD may bring important value to this effort because changes in the eye are easier to measure in relation to other methods necessary to evaluate the health of the brain.  Establishing an evidential correlation between the eye and the brain would suggest that utilizing UWF imaging could provide an easier, more expedient access to that information.  Furthermore, UWF imaging provides a much less expensive option to other methods of evaluation, such as brain scans. The researchers demonstrated that by utilizing optomap, they were able to identify early markers that could manifest many years before dementia develops as well as high risk groups who would benefit from preventative guidance. The study notes that to be a reasonable marker of early disease, pre-symptomatic, or early symptomatic patients would need to be followed up over several years to determine the predictive value of the peripheral findings.  Routine optomap exams could prove to be an earlier, easier and more cost-effective method for monitoring the progression of AD, and identifying individuals at high-risk of developing AD.

UWF Imaging Assists in Discovery and Follow-Up Care of Blunt Eye Trauma

When 29-year-old Emmy came to see Uwe Canting, OD at Canting Optometry in Cary, NC, she was relatively certain that her eye was fine, but wanted to seek reassurance from her optometrist.  Emmy had received a high-impact, full-blown soccer ball to the eye during a soccer match the preceding day and while having no symptoms other than slight discomfort from the bruising, she realized that the impact was severe enough that something unseen may have occurred.

Canting notes that Emmy presented with a black eye OD, while her visual acuity was 20/20.  “The eye itself looked fine. Other than the ecchymosis, there were no immediate concerns. There was no apparent subconjunctival hemorrhage and no recession of the iris.  But, while dilated, I could see instantly that it was not normal and decided to capture an optomap image.  Sure enough, the image clearly showed the whitish sheen of Commotio retinae superiorly temporal.”  Canting recalls, “The beauty of this situation was that I had her optomap image from her last visit and I could show her, clearly and tangibly, what had occurred in her eye.”

He adds that optomap has proved to be extremely valuable for patient education in a variety of scenarios because his patients love to be able to see what he sees and better understand their ocular health. “There is a wonderful opportunity to educate my patients when I use optomap to help explain the anatomy of their eye. If the patient is anxious, we may review the image right away. Otherwise I save it for the end of the exam. If there is an issue I can easily show them, better than it could be explained. Otherwise, it simply puts their mind at ease.” In Emmy’s case Canting could show her the pathology and stress why she should have further examination. Canting referred her immediately to the retinal specialist who reported later that he would be following Emmy’s condition to ensure that no subsequent issues developed.

Commotio retinae is a term that describes the damage that occurs to the outer retinal layers, caused by shock waves that surge through the eye from the impact site of a blunt trauma, such as Emmy’s soccer ball incident.  Often the damage is recognized in the posterior pole but can also manifest, as it did for Emmy, in the periphery where it may be overlooked on a standard central pole retinal view.   While most cases of the condition resolve spontaneously within a month to six weeks, more severe cases can cause temporary or permanent vision loss.  Secondary issues can include choroidal neovascularization, retinal tears, detachment, zonular dehiscence, angle closure glaucoma and lens dislocation.

Rather than shrug off the soccer ball impact injury, Emmy was wise to seek a medical opinion and was fortunate that the injury was not more severe. Canting describes how optomap was a valuable tool in the discovery of the damage and the critical follow-up care that would give Emmy peace of mind.  “She called me later, to tell me how grateful she was that I had seen the issue and had referred her to the specialist for further evaluation.”

As May is Healthy Vision Month, let’s all use  Emmy’s story as a reminder to the importance of the often-overlooked recommendation encouraging protective eyewear for all ages in sports that could involve impact to the eye.

AAO recommends the following Daily Practices for eye health:

  • Regular eye exams to detect subtle changes in the eye
  • Wearing UV protection sunglasses
  • Wearing safety glasses while playing impact sports or doing work about the yard/house that may present hazards to the eye
  • Proper contact lens care
  • Eating a healthy and balanced diet
  • Cessation of smoking
