Primary juvenile glaucoma is a subtype of primary congenital glaucoma that develops due to ocular hypertension and is diagnosed between three years of age and early adulthood. It is caused due to abnormalities in the anterior chamber angle development that obstruct aqueous outflow in the absence of systemic anomalies or other ocular malformation.
Juvenile glaucoma becomes clinically apparent after three years of age and before age 40, according to certain authors. Infantile glaucoma presents between one month and three years, while true congenital glaucoma causes signs of increased intraocular pressure within the first month of life. True congenital glaucoma, infantile glaucoma and juvenile glaucoma together constitute the primary congenital glaucomas.
