Glaucoma is an increased pressure inside of the eye. The fluid inside of the eye is produced by a "faucet" that is always turned on. Normally, there is a "drain" that allows this fluid to exit the inside of the eye into the circulation. Glaucoma means there is something obstructing the "drain," which builds up pressures inside of the eye. Increased pressures cause pain and can permanently damage vision.
Glaucoma can be either primary or secondary. Primary glaucoma occurs when the “drain” was not formed correctly and will eventually affect both eyes. There is no cure for primary glaucoma and the elevated pressure must be controlled with eye drops or specialized procedures. If the patient’s condition does not respond or becomes refractory to medications, an injection or surgical removal of the eye may be considered to keep the patient comfortable.
Secondary glaucoma occurs when there is fluid build up in the eye due to reasons not related to the natural formation of the eye’s “drain.” Causes for this can range from inflammation, to a mass, to a luxated lens - anything that secondarily obstructs fluid drainage from leaving the eye. Secondary glaucoma may not affect both eyes and can be treated by addressing the underlying cause.
Unfortunately, the prognosis for primary and secondary glaucoma is poor and the ultimate goal of treatment is always to maintain the patient’s vision and to keep the patient comfortable for as long as possible.
