Abstract
Apert Syndrome (AS) is a rare form of acrocephalosyndactyly. The aim of the manuscript was to underline the challenging squint management in a case of Apert Syndrome. A 1.5-year-old male with craniosynostosis, diagnosed at birth, with history of incomplete closure of eyes, more so in the right eye, and squinting of left eye since birth, was brought to eye OPD by the mother. Presence of acrocephaly, prominent forehead with bony irregularity, chin down with left head tilt, fused cervical vertebrae, marked proptosis, cleft palate, dental anomaly and syndactyly confirmed the diagnosis of AS. Old serial photographs of the child were examined to look for progression of squint and proptosis. Squint evaluation revealed 70-75 PD exotropia with 10PD right hypertropia in primary gaze. The right hypertropia increased further in the left gaze, whereas a left hypertropia was noted in the right gaze. The patient underwent bilateral LR recession of 9 mm with full muscle width transposition (upshift) with Inferior Oblique recession of 4:1 mm in the right eye and 3:2 mm in the left eye. Post-operative follow-up after 2 months showed that V pattern collapsed with residual exotropia of 20 PD. Post-operative follow-up after 1 year showed improvement in head posture with pattern collapsed. However, recurrent exotropia was noted on evaluation, for which bilateral medial recti resection was done later. The management of squint in AS and other craniosynostosis poses a multitude of challenges for the ophthalmologists. Frequent follow-ups are needed in patients with AS for the timely management of its ocular manifestations and better visual rehabilitation.
