Infant Hemangioma on the Forehead and Secondary Glaucoma: What to Know
Infantile hemangiomas — often called “strawberry marks” — are benign vascular tumors seen in up to ~4-10% of newborns. They usually appear in the first weeks of life and grow for several months before slowly shrinking on their own. Most are harmless, but when they occur near the eye or forehead, extra care is needed because of the potential for ocular complications, including secondary glaucoma.
What Is an Infantile Hemangioma?
An infantile hemangioma is a benign cluster of proliferating blood vessels under the skin. They grow rapidly in early infancy (usually 3-12 months) and then involute (shrink) over time. Most don’t need treatment, but certain locations and sizes can cause problems.
Why Worry About Glaucoma?
Glaucoma is a serious eye condition where elevated intraocular pressure (IOP) damages the optic nerve, risking vision loss. While hemangiomas themselves don’t directly cause glaucoma, certain patterns of vascular growth near the orbit — especially deep or extensive lesions — can indirectly affect ocular structures and lead to secondary glaucoma.
Secondary glaucoma in infants may be rare with just a forehead hemangioma, but documented case reports describe orbital hemangiomas causing proptosis (bulging eye), high IOP, corneal changes, and features that resemble congenital glaucoma.
Signs to Look for in a Newborn
If a newborn presents with:
Epiphora (excessive tearing)
Red or vascular skin lesion on the forehead or near the eye
Visible enlargement of the eye on the same side as the hemangioma
Irritability or photophobia (light sensitivity)
then a careful ophthalmologic evaluation — especially checking IOP — is essential.
Key Examination Steps
Measure Intraocular Pressure – Elevated IOP may be subtle but crucial to catch early.
Examine Corneal Diameter & Clarity – Enlargement or cloudiness can suggest globe distension from high pressure.
Assess Axial Length – A longer eye measurement on the affected side can be a sign of glaucoma.
Check Optic Nerve and Anterior Chamber Angle – This helps understand if the glaucoma pattern is open or closed angle.
If IOP is high or suspicious, inform parents promptly and schedule regular follow-ups — early detection dramatically improves outcomes.
What Literature Tells Us
Case reports show that orbital infantile hemangiomas can present like congenital glaucoma, with high IOP and ocular enlargement. In some cases, treating the hemangioma (e.g., with propranolol) reduced IOP without need for immediate surgery.
Periocular hemangiomas can threaten vision, not just through glaucoma but also by blocking visual axes or inducing astigmatism.
Large facial hemangiomas are sometimes part of PHACE syndrome, which combines vascular lesions with anomalies of the brain, arteries, heart, and eyes — reinforcing the need for multidisciplinary evaluation.
Treatment Plan: What Helps and What Doesn’t
1. Medical Management for the Hemangioma
For hemangiomas that require treatment (e.g., because of size or orbital involvement):
Propranolol (beta-blocker) is the first-line medication and often dramatically reduces lesion size.
Topical timolol may be used for superficial lesions.
Other systemic therapies like sirolimus are sometimes considered in complicated or resistant cases, though such use requires specialist oversight.
Note: Propranolol sometimes lowers IOP indirectly in cases related to vascular effects, but its effect is short-term and not a substitute for glaucoma management.
2. Glaucoma Treatment Options
If secondary glaucoma develops, treatment is tailored to the IOP level, angle anatomy, and age of the child:
Topical Medications — e.g., timolol or carbonic anhydrase inhibitors may be used initially in mild or borderline cases, but efficacy is variable in infants.
Surgical Intervention —
Yes, surgery is often necessary, especially in infants with secondary glaucoma where non-surgical methods fail or the angle is abnormal. However, the choice of procedure is nuanced:
Glaucoma Tube/Shunt Surgery (e.g., Ahmed Glaucoma Valve)
These devices help drain fluid around the eye when the trabecular meshwork is abnormal.
They are commonly used in pediatric secondary glaucoma, including refractory cases, with many centers reporting satisfactory results.
Long-term follow-up is needed because growth can cause tube movement.
Angle Surgery or Filtration Surgeries
Conventional angle surgeries (like trabeculotomy) may be less effective in some secondary forms because the resistance is often outside Schlemm’s canal.
Deep sclerectomy and cyclophotocoagulation are other options, but choice depends on individual anatomy and risk profile.
So, valve (GDD) surgery is one of the most practical solutions in many secondary pediatric glaucomas, but it is not the only option and is chosen based on a specialist’s assessment.
Does Propranolol Help With Glaucoma Before Surgery?
Propranolol primarily treats the hemangioma, not glaucoma. There have been occasional reports of IOP improvement with propranolol in infant cases, but this is not reliable enough to replace glaucoma surgery or IOP-lowering therapy. It might be useful as adjunct therapy to improve vascular congestion or as temporary perioperative support, but should not delay definitive glaucoma management.
Follow-Up and Parental Guidance
Parents should be advised to:
Watch for unequal eye size, prominent tearing, eye redness, or photophobia.
Attend all scheduled eye check-ups, especially in the first 1–2 years.
Understand that vision preservation depends on early intervention.
In Summary
Infant forehead hemangiomas located near the orbit should prompt careful eye evaluation.
Elevated IOP and signs of glaucoma warrant immediate ophthalmologic referral and regular monitoring.
Medical therapy like propranolol effectively treats the hemangioma but does not reliably control glaucoma on its own.
Surgical intervention (including valve surgery) remains central to managing many cases of secondary pediatric glaucoma, tailored to the child’s anatomy and disease severit.#newborn#hemangioma#forehead#glaucoma#valve
