Juvenile open angle glaucoma: current diagnosis and management.

Abstract

The aim of this article is to summarize up-to-date research on the diagnosis and management of juvenile open-angle glaucoma (JOAG). JOAG can be subclassified into four clinical phenotypes, and faster myopic shift is a risk factor for disease progression. Vessel density is associated with structural damage and worsening visual acuity in JOAG and can be monitored with optical coherence tomography angiography. Genetic studies have revealed molecular causes of JOAG including variants in CPAMD8, MYOC, and CYP1B1. Tube shunt surgeries as well as gonioscopy-assisted transluminal trabeculotomy have been shown to be successful in JOAG. Although genetic advances may improve future screening, intraocular pressure monitoring and fundoscopic exam remain the current mainstay of diagnosis. Medical treatment alone for JOAG is typically insufficient with patients requiring surgical management. Selective laser trabeculoplasty may delay or decrease the need for surgery. Trabeculectomy has traditionally been shown to be effective in JOAG, but tube shunt surgery and microinvasive glaucoma surgery are effective alternatives.
