Primary Congenital Glaucoma
Primary congenital glaucoma (PCG), also referred to as congenital or infantile glaucoma, can be evident at birth or become evident within the first few years of life. The pathogenesis of PCG is likely related to arrested development of the anterior chamber angle structures. Histologically, the anterior chamber angle retains an “embryonic” or “fetal” conformation, characterized by the following:
anterior insertion of the iris root
mesenchymal tissue in the anterior chamber angle
poorly developed scleral spur, allowing the ciliary muscle to insert directly into the trabecular meshwork (Fig 7-3)
See BCSC Section 6, Pediatric Ophthalmology and Strabismus, and Section 10, Glaucoma, for detailed discussion of PCG.
