Eye abnormalities in the Smith-Magenis contiguous gene deletion syndrome.
We present the results of ophthalmologic assessment in 10 patients with interstitial chromosome deletions of 17p11.2, otherwise known as the Smith-Magenis syndrome (SMS). The most common abnormalities noted were strabismus, Brushfield spots, high myopia, and retinal detachments. We have previously reported high myopia and retinal detachments in 6 patients with SMS (Finucane et al.: Am J Hum Genet 49:262A, 1991). We present additional details on these individuals, as well as findings in 4 newly reported patients. Ocular pathology appears to be very common in SMS, significantly contributing to disability in people with this syndrome. The combination of high myopia, self-injurious head-banging, aggression, and hyperactivity among these patients makes them particularly susceptible to retinal detachments. Detailed ophthalmologic assessment should be included in the clinical work-up and monitoring of all patients with SMS resulting from deletion 17p11.2.
