What is Glaucoma?

Glaucoma refers to a series of conditions that damage the optic nerve. Usually, this serious problem stems from excess pressure in the eye. Early detection and treatment are vital steps for reducing vision loss and other damage from eye conditions like glaucoma, making it imperative to maintain regularly scheduled eye care visits at our Roseville, CA office. Wilmarth Eye and Laser Center provides a wide variety of eye care services, including complete checkups and glaucoma screenings. Our board-certified ophthalmologist, Dr. Stephen Wilmarth, is highly experienced in the treatment and care of glaucoma.


Increased pressure within the eye (medically known as intraocular pressure) damages the optic nerve and can lead to vision loss and possibly blindness. Pressure can grow within the eye since the flow of fluid nourishing the cornea (aqueous humor) becomes blocked.

In the case of open-angle glaucoma, the most common type of optic nerve damage is very gradual, exhibiting few noticeable symptoms over time except for progressive deterioration of peripheral vision.

Less common but often more serious is acute or angle-closure glaucoma, where structures in the eye block drainage of the fluid and cause intraocular pressure to rise rapidly. Patients should seek help as soon as possible if they experience these symptoms of angle-closure glaucoma:

  • Sudden eye pain
  • Loss of vision
  • Halo shapes around light sources
  • Headache
  • Nausea

Evaluation & Diagnosis

The best defense against glaucoma is regularly scheduled eye exams accompanied by glaucoma screenings. Glaucoma damage isn’t reversible, but the risk to eye health and sight can be more manageable with early detection.

During a full eye care examination, Dr. Wilmarth will test the following to check for glaucoma:

  • Internal eye pressure (tonometry)
  • Field of vision
  • Condition of the optic nerve (dilated pupil exam)
  • Cornea thickness

Starting at age 40, eye doctors recommend undergoing a glaucoma screening in tandem with a full eye exam every 1 – 3 years. Patients aged 60 and older are at the highest risk of glaucoma and should undergo screenings annually.
