Glaucoma
verified Medically reviewed by Dr. Austin Andersen, M.D. · Updated March 2026
Glaucoma is a group of eye conditions that damage the optic nerve, usually caused by abnormally high pressure inside the eye. It is one of the leading causes of irreversible blindness, but early detection through regular eye exams can prevent significant vision loss. Treatment typically involves prescription eye drops to lower intraocular pressure, with laser therapy or surgery for advanced cases.
What Is Glaucoma?
Glaucoma is a group of eye conditions that damage the optic nerve, often due to elevated intraocular pressure. At Professional Eyecare in Overland Park, we use OCT imaging and iCare rebound tonometry to detect glaucoma at its earliest stages, before noticeable vision loss occurs.

When Should You See an Eye Doctor for Glaucoma?
You should schedule a comprehensive eye exam if you have a family history of glaucoma, are over 40, or notice any changes in your peripheral vision. Because glaucoma progresses silently, annual screening is essential for early detection. If you experience sudden eye pain, nausea, or see halos around lights, seek emergency care immediately.
