Juvenile Open-Angle Glaucoma
Juvenile Open-Angle Glaucoma(JOAG) is a rare form of Glaucoma that accounts for approximately 1% of total cases. The clinical features of JOAG are the same as those of more common forms of glaucoma such as POAG (Primarily Open-Angle Glaucoma). JOAG differs from POAG mainly in the severity of disease and age of onset. Patients with JOAG develop disease at a much earlier age than patients with POAG (between 3 and 40 years of age).
JOAG patients also have very high intraocular pressures that frequently exceed 40 mm Hg in the absence of treatment. In many cases, JOAG clearly runs in families as a dominant trait.
