Blepharitis is commonly seen in which populations, according to clinical history notes?

• A. Common in healthy adults.
• B. Common in patients with Down syndrome and eczema.
• C. Common in contact lens wearers.
• D. Common in neonates.

Answer: (D)

Blepharitis is eyelid margin inflammation often tied to inflammatory skin conditions and bacterial colonization. In clinical history notes, it is described as most commonly seen in newborns. This reflects how new-onset lid inflammation can accompany the immature tear drainage system and bacterial colonization typical of the neonatal period, sometimes with crusting and irritation around the lids.

While blepharitis can occur in various groups (for example, in adults with seborrheic dermatitis or rosacea, or in contact lens users who may have lid irritation), the neonatal presentation is the classic association in history notes. Down syndrome and eczema can be associated with ocular surface issues, and healthy adults may develop blepharitis, but these are not the standard neonatal pattern described in typical clinical histories.
