What are common symptoms of blepharitis?

• A. Dry, red, itchy eyelids that may be crusted.
• B. Severe unilateral eye pain with photophobia.
• C. Sudden vision loss and floaters.
• D. Nausea and headaches.

Answer: (A)

Blepharitis involves inflammation of the eyelid margins, often tied to meibomian gland dysfunction or skin conditions. Its hallmark symptoms are dry, red, and itchy eyelids, frequently with crusting along the lash line, especially in the morning. You may also notice a burning or gritty sensation, tearing, and lids that stick together upon waking. These features fit blepharitis best, whereas the other options describe problems with acute eye pain and light sensitivity, sudden vision changes, or nonspecific systemic symptoms that are not typical of lid inflammation.
