Supplementary Material for: PHACE(S) SYNDROME WITH OCULAR INVOLVEMENTS AND NO PERIOCULAR HAEMANGIOMA

PHACE(S) syndrome is a neurocutaneous disorder with a hallmark finding of an infantile facial hemangioma (IFH) > 5cm. Eye examination of patients with PHACE(S) syndrome with no IFH at periorbital region is reported to be of low yield. We report a unique case of the syndrome with ocular manifestations without periorbital IFH or systemic findings. A 3-week-old female infant with right periauricular IFH > 5cm, extending to the neck and cheek and with lower lip IFH. Examination revealed pseudoptosis due to microphthalmia with esotropia and hypertropia. Both corneas were clear with diameters of 5mm and 10mm, right eye (RE) and left eye (LE), respectively. There was a posterior polar cataract with a poor view of the fundus RE. Ocular B-scan and magnetic resonance imaging (MRI) findings were suggestive of a dysmorphic globe, vitreous hemorrhage, spherophakia and persistent fetal vasculature RE and normal findings LE. Clinical evaluation, MRI and MR angiography revealed no other systemic abnormalities. Subsequent follow-up visits revealed progressive clouding of the cornea with neovascularization and the development of phthisis bulbi RE at which point an ocular prosthesis was placed. The IFH was managed with dye laser and with oral propranolol. At one year, the patient has remained stable with no development of new local or systemic anomalies, regression of the periauricular and lip IFH and normal development of the orbital structure RE with an ocular prosthesis in situ. Ocular involvement in patients with PHACE(S) syndrome may be present without periorbital IFH. Regardless of the location of the IFH and the presence or absence of a periocular component, it is recommended that they receive a full initial ophthalmological assessment.
