Glaucoma is a disease that leads to the damage of the optic nerve, the part of the eye that carries visual information from the retina to the brain. It is a leading cause of irreversible blindness world wide. However, if diagnosed and treated early the loss of vision can be prevented. Elevated intraocular pressure (IOP) is a risk factor for glaucoma, but it is not the sole determinant of who will develop the disease. Other risk factors include family history and prior ocular surgeries. At USC Roski Eye Institute we treat the following conditions:

Conditions We Treat

  • Open Angle Glaucoma
  • Angle Closure / Narrow Angle Glaucoma
  • Congenital and Childhood Glaucoma
  • Juvenile Onset Glaucoma
  • Glaucoma Associated with Retinal Diseases

  • Glaucoma Secondary to Steroid Use
  • Pigment Dispersion Glaucoma
  • Pseudoexfoliation Glaucoma
  • Uveitic Glaucoma

Diagnostic Services

Glaucoma-related vision loss most often begins with the decline of peripheral vision. As such, people suffering from the condition generally do not notice the effects of their glaucoma until they have lost a significant portion of their sight. Glaucoma may be detected early on through routine eye exams. Glaucoma specialists examine both the structure and function of the optic nerve to assess its state of health. The earlier glaucoma is detected and treatment is initiated, the more likely visual function can be preserved. At the USC Roski Eye Institute, we provide our patients with state-of-the-art diagnostic services, such as:

  • Visual Field Testing – Standard Automated Perimetry (SAP) and Short Wavelength Automated Perimetry (SWAP)
  • Ultrasound Biomicroscopy (UBM)
  • Optical Coherence Tomography (OCT)
  • Optical Coherence Tomography Angiography (OCTA)
  • Anterior Segment Optical Coherence Tomography (AS-OCT)
  • Corneal Pachymetry
  • Stereoscopic Optic Disc Photography
  • Fluorescein Angiography (FA)

Glaucoma Treatments

When the diagnosis of glaucoma is confirmed, our specialists will develop a personalized treatment plan. This may include non-invasive treatments such as medication and lasers, a minimally invasive glaucoma surgery (MIGS), or an incisional surgical procedure.

Non-Surgical Laser Procedures

  • Laser Trabeculoplasty (SLT)
  • Laser Iridotomy (LPI)
  • Micropulse and Diode Cyclophotocoagulation (CPC)

Minimally Invasive Glaucoma Surgery (MIGS)

  • iStent®
  • Trabectome
  • Kahook Dual Blade
  • Cypass
  • Ab Interno Canaloplasty (ABiC)
  • XEN Gel Stent
  • Endoscopic Cyclophotocoagulation (ECP)

Traditional Surgical Procedures

  • Trabeculectomy
  • Glaucoma Drainage Devices: Ex-PRESS® shunt, Ahmed™, Baerveldt® and Molteno®
  • Femtosecond Laser Technology (in combination with cataract surgery)


At USC Roski Eye Institute, we pride ourselves on providing our patients with cutting-edge diagnostic and treatment options in order to optimize visual outcomes and minimize surgical risks and complications. Whether you have previously been diagnosed with glaucoma or are suffering symptoms that may indicate the presence of the disease, our doctors are here to provide you with care tailored to your specific needs. All of our physicians are fellowship-trained in glaucoma.

Advances in Glaucoma Research

The glaucoma specialists at USC Roski Eye Institute are committed to clinical and scientific research. Several examples are listed below:

  • Development and implantation of the XEN® Gel Stent, a new minimally-invasive treatment for alleviating high intraocular pressure (IOP) in glaucoma patients. The XEN is a soft stent made of collagen-derived gelatin and has been proven to be an effective means of lowering IOP with fewer risks than conventional glaucoma surgery.
  • 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.
  • Applying new forms of optical coherence tomography (OCT) technology, such as OCT angiography (OCTA) and anterior segment OCT (AS-OCT), to better diagnose and manage patients with different forms of glaucoma.
  • Development of novel intraocular pressure sensors to improve disease diagnosis and patient monitoring.
  • Development of a “smart” drug delivery system to control medication dosing and improve patient compliance. The device is an implantable, programmable, wireless pump that delivers precise amounts of medication at proper intervals directly into the eye of glaucoma patients.
  • Collaborations with basic scientists at the Keck School of Medicine to study the pathophysiology and biochemistry of different forms of glaucoma, including pseudoexfoliative glaucoma.

Whether you have been previously diagnosed with glaucoma or are suffering symptoms that may indicate the presence of the disease, the staff at the USC Roski Eye Institute can provide you with cutting edge care. All of our physicians are American board certified and fellowship trained subspecialists. Learn more by visiting the American Academy of Ophthalmology‘s glaucoma page.
