Glaucoma is a leading cause of blindness and affects over three million Americans; however only 50% of those with glaucoma know they have it. Because there are often no presenting symptoms, glaucoma is often referred to as the silent thief of vision. Though glaucoma can cause permanent vision loss and there is no cure, early detection and treatment can prevent complete blindness.

The Yale Glaucoma Department is comprised of internationally respected physicians and research scientists who seek to decrease preventable blindness from glaucoma through medical and surgical management, research, and community awareness. Dr. Christopher Teng, Dr. Ji Liu, Dr. Soshian Sarrafpour, and Dr. James Martone offer a complete range of services for patients with glaucoma and related anterior segment diseases. With continued study to improve their understanding of the diagnosis and management of glaucoma, our physicians offer the latest advances in diagnosing and treating all forms of glaucoma. Our physicians are fellowship trained and engage in and keep up with all the latest research. We offer the most sophisticated technologies and techniques in the field. Most importantly, our physicians get to know you as a person, not just as a patient, and they work with you to protect your vision.

The Yale Glaucoma Service utilizes the most technologically advanced instrumentation including computerized perimetry, Swept Source and Spectral Domain Optical Coherence Tomography (OCT), OCT angiography, high-resolution wide field Optos fundus photography, ultrasound biomicroscopy and Pascal, Argon, SLT, Nd-YAG, and micropulse laser systems. The state-of-the-art operating rooms have the most advanced equipment including Femtosecond laser, intraoperative aberrometry, the newest operating microscopes and phacoemulsification systems, and the most cutting-edge devices for surgical glaucoma management.

Special services offered include:

  • Cataract surgery: no stitch cataract surgery, femtosecond laser assisted cataract surgery, and interoperative aberrometry
  • The most advanced intraocular lens options including trifocal lenses, multifocal lenses, extended depth of focus lenses, and toric lenses
  • Surgeries for dislocated lenses, lens exchanges and repositionings, pupil repair surgeries, and complex cataract surgeries
  • Computerized and manual visual field assessment with custom programs
  • Optical Coherence Tomography and Angiography
  • Gonioscopy, slit lamp examinations, optos wide field fundus photography, and ultrasound biomicrocopy
  • Laser procedures including Pascal Synthesis Ophthalmic Scanning Lasers, Argon laser procedures, YAG capsulotomies and iridotomies, selective laser trabeculoplasty (SLT), and micropulse laser procedures
