The eye and Down's syndrome
Down's syndrome is a common genetic abnormality that can affect most parts of the eye. Common ocular features are described, as well as those which cause reduced vision, requiring referral to an ophthalmologist.

- "As found in other studies, blepharitis and conjunctivitis, both inflammatory conditions of the eye, were found to be common conditions in individuals with Down syndrome. Blepharitis may be related to the narrow, slanted palpebral fissures characteristic in individuals with Down syndrome  or an increased susceptibility to infection associated with the impact of trisomy 21 on the immune system [22, 55, 56].

ABSTRACT: A myriad of ophthalmic disorders is associated with the phenotype of Down syndrome including strabismus, cataracts, and refractive errors potentially resulting in significant visual impairment. Ophthalmic sequelae have been extensively studied in children and adolescents with Down syndrome but less often in older adults. In-depth review of medical records of older adults with Down syndrome indicated that ophthalmic disorders were common. Cataracts were the most frequent ophthalmic disorder reported, followed by refractive errors, strabismus, and presbyopia. Severity of intellectual disability was unrelated to the presence of ophthalmic disorders. Also, ophthalmic disorders were associated with lower vision-dependent functional and cognitive abilities, although not to the extent that was expected. The high prevalence of ophthalmic disorders highlights the need for periodic evaluations and individualized treatment plans for adults with Down syndrome, in general, but especially when concerns are identified.

ABSTRACT: Down syndrome (DS) is associated with various uncommon dermatological disorders and increased frequency of some common dermatoses. This study was conducted over a 2-year period to evaluate the frequency of phenotypic and dermatologic manifestations in patients with Down syndrome in south India. The most common phenotypic manifestations that characterize DS include the epicanthic fold (93.7%), brachicephaly (90.6%), flat nasal bridge (84.2%), upward angle of eyes (83.2%), wide gap between first and second toe (81.1%), clinodactyly (77.9%), small nose (74.7%), short broad neck (72.6%), single palmar crease (61.1%), increased nuchal skin fold (61.1%), and fissured tongue (52.6%). The most common dermatological manifestation seen in patients with DS were lichenification, xerosis, dental anomaly, fine, sparse hair, and delayed dentition. Alopecia areata was seen in 9.4 percent of patients and tended to be severe. Infections were relatively less common in our study. Our study has highlighted many phenotypic features and dermatoses, which may help provide better care for patients and counseling to the families.
