Periocular haemangioma of childhood can severely impact visual development.
Objective(S):
To review our experience with 20 periocular haemangioma patients; to review infant ocular development in the context of periocular capillary haemangioma; to identify early clinical warning signs that may precede devastating visual outcomes in the absence of timely management and to review our experience with surgical debulking for the treatment of selected periocular haemangioma.
Design:
Retrospective case series.
Interventions:
Twenty children with congenital periocular haemangiomas received care by a multidisciplinary team consisting of doctors from the specialties ophthalmology, plastic surgery, paediatrics and dermatology. The patients were separated by age at presentation to our centre (
Results:
Patients presenting to our centre after 1 year of age were more likely to have amblyopia (75% vs. 0% if presenting at
Conclusion:
Early identification and multidisciplinary treatment of 'high risk' periocular haemangiomas, at imminent risk of causing amblyopia, is essential. Some 'high-risk' lesions are clinically deceiving and display an apparent open visual axis. Early surgical debulking of these lesions can provide immediate decompression of the globe and allow for preservation of normal vision. Conversely, a 1-2-week period of visual deprivation, in children under 2 years of age, can result in permanent cortical visual deficits.
