Why you need to beware of potential mimickers of paediatric glaucoma
Take-home: Some rare paediatric conditions can be mistaken for early childhood glaucoma.
Primary congenital glaucoma (isolated goniodysgenesis) is often a straightforward diagnosis. Classic phenotypic features include increased measured IOP, corneal haze/scarring with associated astigmatism, corneal enlargement (megalocornea) with globe enlargement (buphthalmos) and associated myopia, Descemet membrane breaks (Haab striae), iris atrophy and optic nerve cupping. These findings also occur in early developmental glaucoma. However, although the diagnosis of primary congenital or early developmental glaucoma is usually straightforward, similar phenotypic features can occur in other paediatric conditions, which are sometimes mistaken for early childhood glaucoma. Ophthalmologists who care for children with glaucoma must keep such potential mimics of paediatric glaucoma in mind.
