Ophthalmic pathology of Nance-Horan syndrome: case report and review of the literature.
BACKGROUND: Nance-Horan syndrome (NHS) is a rare X-linked disorder typified by dense congenital central cataracts, microcornea, anteverted and simplex pinnae, brachymetacarpalia, and numerous dental anomalies due in most cases to a mutation in the NHS gene. MATERIAL AND METHODS: We present a case of clinical manifestation and ocular pathology in a patient with NHS. This article also reviews and discusses the relevant literature. RESULTS: Classic and novel ocular pathological findings of a young male with NHS are described, including congenital cataracts, infantile glaucoma, scleral staphyloma, and severe retinal cystoid degeneration. CONCLUSIONS: We report a new pathological finding of severe retinal cystoid degeneration in this NHS patient and confirm abnormal development of the anterior chamber angle structure. These findings, coupled with our analysis of the available NHS literature, provide new understanding of the histopathological basis of ocular abnormalities and vision loss in NHS.[1]References
