OCT Scans Show Promise in Monitoring Neurodegeneration in Multiple Sclerosis
PLEASANTON, CALIFORNIA - Optical coherence tomography (OCT) scans may offer a valuable tool for quantifying and monitoring neurodegeneration in patients with multiple sclerosis (MS) or a history of optic neuritis, even without a formal MS diagnosis, according too a outlook published by the American Academy of Optometry. The findings underscore the importance of a holistic approach to patient assessment for optometrists, recognizing the retina as an extension of the central nervous system.
While a recent Swedish study highlighted the potential for OCT to detect retinal nerve fiber layer thinning in MS patients, the author, Lily Nguyen, OD, FAAO, of Total Vision Pleasanton, emphasizes the broader clinical implications.”As the retina is an extension of the central nervous system, it is imperative that optometrists take a holistic approach when assessing patient health,” Nguyen wrote. “Whether it be a wellness OCT scan or a focused medical visit, it is important to review systemic health and consider alternative causes of macular thinning outside of ‘typical’ ocular pathology.”
OCT scans provide detailed cross-sectional images of the retina, allowing clinicians to measure the thickness of various retinal layers.In MS, neurodegeneration can manifest as thinning of the retinal nerve fiber layer and other retinal structures. This non-invasive imaging technique could provide an objective measure of disease progression and response to treatment.
For established MS patients and those with a history of optic neuritis but no definitive MS diagnosis,Nguyen suggests OCT scans may be warranted to track potential neurodegeneration.The perspective highlights the need for optometrists to consider systemic health factors and explore causes of macular thinning beyond customary ocular diseases.
Nguyen reported no relevant financial disclosures. This perspective was powered by the American Academy of Optometry’s Communications Committee.
