Congenital glaucoma (CG), diagnosed in the first year of life, can fall into three main groups: primary CG, glaucoma associated with congenital anomalies, and secondary glaucoma of infants. The associated congenital anomaly of CG includes the autosomal dominant: Marfan Syndrome (MS), the phenotypic features of which would rarely be evident in the first year of life. Multiple other associated autosomal dominant, autosomal recessive, X-linked and chromosomal conditions that can present with CG need to be excluded. Hence, this is a retrospective diagnosis and is the first known documented case report in an Afro-Caribbean with MS presenting with CG at six weeks of age. The Marfanoid features became apparent in late childhood and adolescence.
