Senile scleral plaques are benign, age-related changes in the sclera (the white part of the eye) that are common in older individuals. These plaques typically appear as well-defined, greyish, or whitish areas, often located just in front of the insertion points of the horizontal rectus muscles. While usually asymptomatic, they can sometimes become calcified and appear more opaque.
Key characteristics of senile scleral plaques:
Age-related: Primarily found in older individuals, with prevalence increasing with age.
Location: Commonly situated just in front of the medial and lateral rectus muscle insertions.
Appearance: Greyish, well-defined, and sometimes rectangular or ovoid areas of increased scleral translucency.
Calcification: May undergo calcification, becoming more opaque and white.
Symptom: Generally asymptomatic, but can be mistaken for foreign bodies on imaging.
Prevalence: Increases with age, with some studies indicating a prevalence of 25% in those aged 80 and over, according to Radiopaedia.org.
Etiology: Believed to be caused by a combination of factors including actinic damage (sun damage) and tractional forces from eye muscles, according to the National Institutes of Health (NIH).
