Ocular findings in Down's syndrome.

This communication presents the ocular findings in 30 patients with Down's syndrome residing in a central institution for the mentally retarded. The findings have been compared to those in matched controls consisting of mentally retarded people from the same institution. The ocular status in patients with Down's syndrome has been extensively studied previously, and to a large extent, findings in previous materials were confirmed. However, in this institution, which consisted of adult patients only, some unusual findings have also been made: nine of the 30 patients had keratoconus, which is a remarkably high figure. A compilation of data shows that only one of the patients with Down's syndrome had nearly normal ocular status.
