Periocular Asymmetry in Infants with Deformational Posterior Plagiocephaly

ABSTRACTPurpose: To analyze the clinical significance of the periorbital features associated with the facial asymmetry that is common in deformational posterior plagiocephaly (DPP).Patients and methods: We identified 32 patients with DPP, photographed their faces and tops of their head, and performed a complete eye examination. Four examiners analyzed the patient’s periorbital features on the photographs.Results: Median age was 6.5 months (range 3–12 months). Pseudoptosis was identified in 30 patients and pseudo-brow ptosis in 19. Pseudoptosis was marked in 17 patients. Five patients were misdiagnosed with congenital blepharoptosis and received regular follow-ups for amblyopia checks until the diagnosis of pseudoptosis was established. All patients had normal levator function and symmetric eyelid crease. One patient with pseudoptosis and physiologic anisocoria was diagnosed with pseudo-Horner syndrome after a negative 10% cocaine test. None of the patients developed meridional or occlusion amblyopia.Concl...
