Steroid (Corticosteroids) Eyedrops
These eyedrops are extremely potent and should be used only under your ophthalmologist’s guidance. Using them for an eye problem without telling your ophthalmologist is dangerous.
Whenever corticosteroids are used, they reduce your eye’s ability to fight infection and to repair injury. Using them over time can lead to glaucoma or cataracts, which can cause loss of vision.
In spite of the risks, the benefits of using steroids are so important in treating certain conditions that they must be prescribed. The generic names of common corticosteroids are:

Glaucoma is a disease of the optic nerve often related to high pressure inside the eye. Glaucoma is a leading cause of blindness, but loss of sight from glaucoma can be prevented with early treatment. Eyedrops applied every day are used to lower the pressure within the eye.
Glaucoma medications reduce the fluid pressure in the eye either by decreasing the amount of fluid forming in the eye or by increasing the eye’s ability to drain fluid. This fluid, called aqueous humor, is inside the eye and is different from your tears.Steroid (Corticosteroids) Eyedrops These eyedrops are extremely potent and should be used only under your ophthalmologist’s guidance.
