2. Blurred vision in 74-year-old man
What mineral has been shown to be at the center of these lesions?
In this image, there is a collection of both small hard drusen in the perivascular area of the macular and softer drusen (video). The softer drusen appear greyish-white in coloration, versus the highly refractile hard drusen. This patient was diagnosed with dry AMD.
Recent research from the Age-related Eye Disease Study (AREDS) has linked calcium supplementation to a lower incident risk of advanced AMD (Tisdale et al. JAMA Ophthalmology, 2019).
In this journal club's accompanying 17 min. video, Dr. Sharma will review:
- The difference between prevalence and incidence
- The biologic plausibility of calcium being linked to drusen
- What to tell your AMD patients on calcium
