Meet the Orbit & Eye Movement Institute Team

The Orbit & Eye Institute in The Vision Center at Children's Hospital Los Angeles is dedicated to providing children and their families with the latest treatment strategies for strabismus, a disorder that causes one eye to be misaligned with the other when focusing, and for amblyopia, loss of vision in one eye. Led by Angela Buffenn, MD, our medical team is on the forefront of research for ocular misalignment. Each patient is designed an appropriate treatment program, which may include, for example, a combination of eyeglasses, patching or surgery. Early intervention is critical and typically effective. We specialize in addressing ocular misalignment with computer-assisted orthoptics or eye exercises and comprehensive rehabilitation after surgery.

The Vision Center is actively involved in the Eye Disease Investigator Group, a collaborative network funded by the National Eye Institute and dedicated to facilitating multicenter clinical research in strabismus, amblyopia and other eye disorders that affect children.

The Orbit and Eye Movement Institute specializes in ocular misalignment, with a comprehensive program of treatment and research into:


Orbit and Eye Movement Institute Research

Under the direction of Dr. Buffenn, research priorities include exam techniques for detecting ocular disease in infants and children, amblyopia and various forms of strabismus.

Research into the usefulness of the Red Reflex test in The Vision Center at Children’s Hospital Los Angeles is to determine the presence of eye diseases in children. “Red Reflex” refers to the red-orange spot in the center of the pupil (black spot in the center of the eye) that is made by the light that reflects out of the eye (like “red eye” from a camera flash). The test is done by shining a special light into the child’s eye. In this study, we evaluate exam techniques for detecting disease in children.
