Ophthalmic Ultrasound Services

The Kellogg Eye Center offers extensive ophthalmic ultrasound services to assist physicians in the diagnosis and treatment of ocular and orbital diseases. The service is staffed with highly trained, certified technicians who perform more than 1,400 ultrasounds each year.

State-of-the-art ultrasound technology allows us to provide you with evaluations of the anterior segment of the eye as well as the eye’s intraocular and orbital structures. We perform ultrasound procedures for both adult and pediatric patients. After the tests are reviewed by a Kellogg physician, we send a report—usually on the same day as testing—to the referring physician. These reports will be digitally saved.

Ophthalmic ultrasound can help physicians:

  • Detect and differentiate intraocular and orbital tumors
  • Detect vitreoretinal diseases
  • Detect inflammatory diseases
  • Detect optic nerve diseases
  • Detect and differentiate types of glaucoma
  • Take extraocular muscle measurements for Thyroid Eye Disease
  • Locate intraocular lens position after cataract surgery
  • Detect ocular trauma
  • Complete A-scan biometry for axial length measurements prior to cataract surgery

Kellogg uses the Eye Cubed™ system, with real-time imaging and advanced movie technology, with a platform equipped for:

  • 10 MHz Posterior Segment
  • 40 MHz Wide Field Anterior Segment – Ultrasound Biomicroscopy (UBM)
  • Standardized Diagnostic A-scan
  • Axial Length Biometry A-scan
