Ten patients presented with lid abnormalities leading to corneal problems. Five patients had ectropion, four of whom required skin grafting to correct the abnormality. One patient had entropion and four had chronic blepharoconjunctivitis leading to trichiasis, which was treated with double freeze thaw cryotherapy. Down's syndrome is associated with a wide variety of ECTROPION GROUP (FIVE PATIENTS) anatomical and biochemical abnormalities including Four patients had bilateral upper and lower lid congenital mental retardation, congenital heart ectropion as a result of severe lid skin shortage (Fig. defects, immune-system deficiencies, and ocular 1), and two developed spontaneous eversion of the abnormalities-most commonly cataracts, kerato- lids during sleep and on crying (Fig. 2). All had poor conus, Brushfield spots, and strabismus.

Patients and methods Fifty four patients with Down's syndrome who had attended the hospital were studied; of these 10 had eyelid problems directly related to their disease, and the rest had other congenital ocular abnormalities. There were five male and five female patients. The age range at presentation was 7 months to 55 years. Correspondence to J R 0 Collin, Moorfields Eye Hospital, City Road, London EC1V 2PD.
