Parents notice a soft swelling near the nose. Tears collect on the lid margin. Redness can appear if infection begins. Feeding or crying can make the bulge more clear. Some cases progress to discharge.

A dacryocele is a tear sac cyst that can cause swelling near the inner corner of the eye and can become infected.
