Childhood Glaucoma

Abstract

The glaucomas arising in children comprise a diverse group of developmental and secondary disorders. Until the mid-20th century, childhood glaucoma was a uniformly blinding disease. The development of surgical approaches like goniotomy ab interno (1940s) and trabeculotomy ab externo (1960s) provided the first effective treatments for this group of uncommon disorders. Since then, additional progress in the management of adult glaucoma has quickly found its way to childhood glaucoma-including the use of antimetabolites, modern glaucoma drainage devices, and techniques of circumferential ab interno and ab externo trabeculotomy using sutures or an illuminated microcatheter. Each of these techniques requires modifications to be safely used in infants and young children. The nomenclature and classification of the pediatric glaucomas were standardized in 2013 with the Childhood Glaucoma Research Network classification system which was a foundational step in developing registries and coordinated research in the field. Modern tools of molecular genetics have begun to elucidate the underlying molecular pathophysiology and inheritance of some forms of childhood glaucoma. Single-gene, Mendelian-inherited forms of childhood glaucoma may be ideal targets for clustered regularly interspaced short palindromic repeats (CRISPR) gene-editing technologies to correct the disorder locally in the anterior chamber angle. All these advances greatly improved visual outcomes in childhood glaucoma. However, with the greatly improved visual prognosis in childhood glaucoma come unique considerations in how we care for these patients over a very long lifespan.
