PURPOSE: The Smith-Magenis syndrome (SMS) is a multiple-anomaly, mental retardation syndrome associated with deletions of a contiguous region of chromosome 17p11.2. Prior reports have described ophthalmic anomalies with SMS, including telecanthus, ptosis, strabismus, myopia, iris anomalies, cataracts, optic nerve hypoplasia, and retinal detachment. This report defines the ophthalmic spectrum in 28 individuals with SMS subjected to a multidisciplinary clinical and molecular survey.
METHODS: Individuals with deletion of chromosome 17p11.2 detected by high-resolution cytogenetic analysis underwent complete ophthalmologic evaluation comprised of ophthalmic history, visual acuity, cycloplegic refraction, motility, and biomicroscopic and ophthalmoscopic examination.
RESULTS: Among the 28 subjects, ranging in age from 0.8 to 29.3 years, the most frequent ocular findings were iris anomalies (68%), microcornea (50%), myopia (42%), and strabismus (32%). Bilateral microphthalmos with uveal and retinal coloboma was observed in one individual. No subject had cataract or retinal detachment.
CONCLUSIONS: This is the largest single-center series of subjects with SMS that includes ophthalmic evaluation. As in prior reports, iris anomalies and strabismus were observed, but microcornea had not been noted previously. The absolute refractive error was hypermetropic in half of these subjects. Cataract, ptosis, and retinal pathology, including detachment, were not observed in any subject. All individuals with SMS should be evaluated by an ophthalmologist, with special attention to strabismus, microcornea, iris anomalies, and refractive errors.
