Ocular complications of autoimmune polyendocrinopathy syndrome type 1.

PURPOSE: To report the ocular complications in a series of patients with autoimmune polyendocrinopathy syndrome, type 1 (APS1). METHODS: A retrospective study of 17 patients with APS1 syndrome treated at the department of ophthalmology, Our Lady's Hospital for Sick Children in Crumlin, Dublin, Ireland. All patients had clinical manifestations of the disease in keeping with the diagnostic criteria of APS1. Each patient had a comprehensive ophthalmic history taken and examination, including ocular symptoms, best-corrected visual acuity, slit-lamp biomicroscopy, tear film evaluation, and dilated ophthalmoscopic examination. RESULTS: Six of 17 patients (35%) had corneal changes. Two patients (12%) had severe keratoconjunctivitis requiring hospitalization and intensive topical steroids and lubricants. The inflammation resulted in visual acuity reduction in one patient secondary to central corneal scarring. Other ocular findings included reduced tear production, as tested with Schirmers tear strips (63%), lens opacities (18%), hypotrichosis (12%), hypertrichosis (5.9%), anisometropic amblyopia (5.9%), and myopia (5.9%). CONCLUSIONS: The most common and clinically important ocular manifestation of APS1 was keratoconjunctivitis associated with dry eye. This can result in progressive corneal scarring and vision loss.

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) in the Irish population.

OBJECTIVE: To determine the Irish prevalence of autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED), the AIRE mutations involved and clinical features of this population. METHODS: All patients were identified through paediatricians and endocrinologists in Ireland. Patients were invited to attend a multidisciplinary clinic. RESULTS: Thirty-one patients (2-56 years), 18 female, were identified from 19 families giving an Irish prevalence of 1:130,000. Twenty-six patients had hypoparathyroidism, 21 had adrenal insufficiency (AI) and 10 of 16 had ovarian failure. Three affected patients have died. Many with hypoparathyroidism were resistant to 1-alpha-vitamin D. Two needed daily PTH injections. Mineralocorticoid deficiency as the first manifestation of AI was common. Chronic intra-oral candidiasis affected 25 patients and three had leukoplakia. Two had keratoconjuntivitis. Of 22 with AIRE gene analysis, three different mutations were identified, one of which is novel. CONCLUSION: APECED is rare in Ireland. We saw a significant amount of non-endocrine disease but no ectodermal dystrophy. AIRE gene analysis reassured many siblings and identified individuals with APECED prior to any symptoms.

Septo-optic dysplasia with digital anomalies--a recurrent pattern syndrome.

A distinct form of septo-optic dysplasia (SOD) comprises limb malformations in addition to the characteristic CNS and ocular abnormalities. To date, there have been 4 reports, citing 5 affected patients with this combined phenotype. We now add a further case and present neuroradiological images of the CNS findings in this condition. The striking consistency of the limb malformations and their overlap with the Streeter's band phenotype is emphasized.
