    Abstract

    Aim: This study describes, in detail, the phenotype of late-onset retinal macular degeneration (L-ORMD) an inherited condition affecting both the retina and anterior segment. A staging based on clinical characteristics is proposed, and the relevance of this condition to current understanding of age-related macular degeneration is discussed.

    Methods: A systematic review of the literature regarding this condition supports a detailed description of the natural history. Clinical experiences in identifying, monitoring and managing patients are also presented.

    Results: L-ORMD is a rare fully penetrant autosomal dominant condition resulting from a mutation in the C1QTNF5 gene on chromosome 11. Affected individuals develop bilateral loss of vision, dark-adaptation abnormalities, fundus drusen-like yellow spots, midperipheral pigmentation, choroidal neovascularisation, chorioretinal atrophy and long anteriorly inserted lens zonules. Patients may benefit from treatment with high-dose vitamin A.

    Conclusions: Raised awareness of L-ORMD should lead to earlier diagnosis and improved care for patients. New antivascular endothelial growth factor treatment may provide a new possibility for management. A deeper insight into molecular and genetic mechanisms of L-ORMD may suggest avenues to explore new treatments of this disorder.
