Masses and cysts of the eyelid and periocular region that are present at birth or appear in the first months arise from how tissues formed during embryonic development. The great majority are benign. Even so, anything occupying space in this region can affect eyelid movement, the position of the globe and the visual axis, so it deserves assessment.
Benign does not mean unimportant. A small dermoid cyst may sit quietly for years, whereas a mass that pulls the eyelid down or casts a shadow across the visual axis affects visual development directly and can lead to amblyopia. The decision to observe or to treat therefore rests on the effect on the eye, not on the appearance.

As an Ophthalmologist, Dr. Ayşe Dolar Bilge, I provide diagnosis and treatment services with my experienced team.
Dermoid cysts do not disappear on their own; they enlarge slowly and are treated surgically. Most haemangiomas, by contrast, grow in the first months and then shrink over the following years. Distinguishing the two changes the treatment completely, so examination is essential.
Surgery is advised when the lesion restricts lid movement, covers the pupil, presses on the cornea and induces astigmatism, enlarges rapidly, or causes repeated inflammation. In the absence of these, regular follow-up is appropriate, tracking size, lid position and vision together.
Yes. A mass that blocks the visual axis or pulls the eyelid down prevents a sharp image reaching the retina and can lead to amblyopia. Masses pressing on the cornea induce astigmatism and can end the same way. Every child with such a lesion therefore has a vision assessment and cycloplegic refraction.
When a dermoid cyst is removed intact with its capsule, recurrence is not expected. If the cyst ruptures during surgery and its contents spill into the surrounding tissue, an inflammatory reaction and recurrence can follow, which is why the procedure aims to keep the cyst wall intact.
The incision is placed in a natural line such as within the brow or the lid crease so that the scar is concealed. Because the skin here is thin, scars usually remain faint. Full maturation takes months, and the early redness and firmness settle with time.
The great majority of congenital periocular masses in children are benign. Even so, a lesion that grows rapidly, displaces the globe, restricts eye movements, bleeds or breaks down the overlying skin needs detailed investigation, in which imaging is decisive.
