Classification of Glaucoma
1. Congenital glaucoma
2. Acquired glaucoma
1. Congenital glaucoma
Defect in angle of anterior chamber obstruct outflow of aqueous humor, causing damage to optic nerve.
a. True congenital glaucoma
IOP raised during intrauterine life.
b. Infantile glaucoma
c. Juvenile glaucoma
2. Acquired glaucoma
a. Primary open angle glaucoma (POAG)
Primary open angle glaucoma/ glucoma simplex/ chronic open angle glaucoma.
Result from overproduction or obstruction of outflow of aqueous humor through trabecular meshwork or schlemm's canal, causing increased IOP and damage to optic nerve.
Primary open-angle glaucoma occurs when drainage channels are open, but fluid do not drain properly.
b. Primary angle closure glaucoma/ narrow angle glaucoma/ pupil block glaucoma/ acute congestive glaucoma
Obstruction cause narrow angle between bulging anterior iris and posterior corneal where drainage angle of eye is located.
Thickened iris/ Bulging iris; bulging iris press on trabecular network closing angle.
b. Secondary glaucoma
Secondary glaucoma result of another disease problem such as;
Uveitis (inflammation in middle layer of eye; uvea).
Intraocular hemorrhage
