The document discusses different types of glaucoma, including primary congenital glaucomas, primary open angle glaucomas, and primary angle closure glaucomas. Primary congenital glaucoma is caused by angle dysgenesis and impaired aqueous outflow, presenting from birth to age 2 with large eyes, corneal edema, and elevated intraocular pressure. Primary infantile glaucoma has a similar etiology but later onset from ages 3 to 10. Glaucoma can also be associated with certain congenital anomalies. The autonomic nervous system regulates aqueous secretion through adrenergic receptors.
