In congenital glaucoma, children are born with a defect in the angle of the eye that slows the normal drainage of fluid. These children usually have obvious symptoms, such as cloudy eyes, sensitivity to light, and excessive tearing. Conventional surgery is typically the suggested treatment, because glaucoma medications may have unknown effects in infants and can be difficult to administer. Surgery is safe and effective. If surgery is done promptly, these children usually have an excellent chance of having good vision.

 

Secondary glaucoma can develop as a complication resulting from other medical conditions. This type of glaucoma is sometimes associated with:

 

Pigmentary glaucoma occurs when pigment from the iris flakes off and blocks the meshwork, slowing fluid drainage. A severe form, called neovascular glaucoma, is linked to diabetes. Corticosteroid drugs used to treat eye inflammation and other diseases can trigger steroid-induced glaucoma in some people.
