Abstract

Purpose: To characterize ophthalmic findings in patients with tetrasomy 18p, a rare chromosomal anomaly that has been previously associated with strabismus. Methods: All subjects underwent a complete eye examination to screen for ocular pathology. Results: A total of 25 subjects (13 female) were examined after they were diagnosed with tetrasomy 18p. The average age of subjects was 8.2 years (range, 13 months to 22 years). Of the 25 subjects, 18 (72% of examined subjects, 42% of the cohort) showed evidence of strabismus; 16 had esotropia (8 uncategorized, 5 infantile, and 3 accommodative), 1 had esophoria, and 1 was diagnosed with intermittent exotropia. Conclusions: The coincidence of esotropia with tetrasomy 18p indicates the need to routinely screen these patients for strabismus at the time of diagnosis.
