Care at Milton S. Hershey Medical Center

At Penn State Eye Center, our specialists are skilled at treating all types of glaucoma. Our glaucoma surgeons have more experience with specific glaucoma procedures than you’ll find at most eye centers. We feature the latest diagnostic technology, operated by staff who have special training and certification.


To diagnosis glaucoma, we’ll perform a complete eye exam, which includes:

  • Tonometry, a test that checks your eye pressure
  • Gonioscopy, examination of the drainage system of the eye
  • Pachymetry, measurement of your corneal thickness
  • Examination of your optic nerve

We may order additional tests to confirm your diagnosis, such as optic nerve imaging and visual field testing.

Our treatment focuses on preventing further vision loss. Your treatment will depend on the type of glaucoma you have.

  • If you have open-angle glaucoma, the most common type, your doctor will likely give you medicated eye drops to lower the pressure in your eye.

Your treatment may also include laser procedures. Eye surgery is sometimes performed in the operating room for glaucoma, which may include cataract removal, trabeculectomy, or glaucoma drainage device insertion.

  • Closed-angle glaucoma may be a medical emergency in some variants of angle closure, but is also may be chronic in nature. It occurs when the intraocular drainage system in the angle of the eye (trabecular meshwork) is blocked.

Treatment for this type of glaucoma also involves medications, such as eye drops. However for this type of glaucoma, you may require an iridotomy, which uses a laser to open a new channel in your iris. Closed-angle glaucoma is also treated surgically, in some cases, with cataract removal, trabeculectomy, and glaucoma drainage shunts. 


Treatment for diabetic retinopathy involves interdisciplinary care from several departments, including:

Research & Clinical Trials

We have an active clinical science research program, and we frequently seek volunteers to participate in clinical trials. These studies help our scientists improve diagnostic techniques, develop better treatments, and collaborate with other researchers.

Symptoms, Diagnosis & Outlook

Glaucoma refers to a group of eye diseases that damage the optic nerve, usually through the buildup of fluid in the front part of the eye. Glaucoma leads to progressive vision loss, but blindness can often be prevented with early treatment.
