Diagnostic Services

Glaucoma-caused vision loss most often begins with the loss of peripheral vision. As such, people suffering from the condition generally do not notice that they have glaucoma until it has taken away a significant portion of their sight. Glaucoma may be detected early through routine eye exams. The sooner treatment can begin, the less vision capabilities that are lost. For early detection, eye specialists must directly examine the optic nerve and peripheral vision, and not just rely on pressure tests such as the standard puff tests, which check for high pressure. Our glaucoma service offers state-of-the-art diagnostic technology, including non-invasive tools such as:

  • Automated Perimetry [White on White and Blue on Yellow (Short Wavelength)]
  • FDT (Frequency Doubling Technology)
  • B-Scan Ultrasonography
  • Cirrus Optical Coherence Tomography
  • Heidelberg Retinal Tomography
  • Pachymetry to Measure Corneal Thickness
  • Stereoscopic Optic Disc Photography
  • Color Vision Testing

Glaucoma Treatments

Once diagnosed, our glaucoma specialists will determine the most optimal treatment plan and assess if non-invasive procedures such as medications and lasers are more suitable than a surgical approach.

Non-Surgical Laser Procedures

  • Cyclophotocoagulation
  • Laser Iridotomy
  • Laser Trabeculoplasty

Surgical Procedures

  • XEN Gel Stent (minimally invasive)
  • Trabeculectomies
  • Glaucoma Drainage Devices: Ex-PRESS® shunt, Ahmed™, Baerveldt® and Molteno®
  • iStent® and Trabectome (minimally invasive)
  • Femtosecond Laser Technology (both glaucoma and cataract procedures can be performed)

Advances in Glaucoma Research

Our Glaucoma researchers have made great strides in advancing the field. Several examples are listed below:

  • Rohit Varma, MD, MPH, and his team of researchers at the USC Ocular Epidemiology Center have conducted the Los Angeles Latino Eye Study (LALES) from 1998 to 2014 in adult Latinos aged 40 years and older. The US Centers for Medicare began providing a glaucoma screening benefit to Latinos aged 50 years and older as a result of the high rate of glaucoma reported in Dr. Varma’s study.
  • The USC Roski Eye Institute is conducting National Eye Institute-sponsored, multicenter clinical trials studying the efficacy and safety of early surgery in the treatment of glaucoma.
  • Development of novel intraocular drainage devices, intraocular pressure sensors as well as drug delivery systems that will improve quality of life of our glaucoma patients.
  • Development of a “smart” device to control medical dosing. A tiny, implantable pump delivers precise amounts of medication as required at proper intervals directly into the eye of glaucoma patients. It is refillable, and is programmed and recharged wirelessly. For a more detailed description please visit: /basic-translational-research/.
  • Development of a more effective, less invasive treatment for alleviating high intraocular pressure (IOP) in glaucoma patients; a soft stent made of permanent, collagen-derived gelatin creates a pathway for drainage that has been proven effective to lower IOP and is preferred by physicians worldwide.
