About our Doctors

Dr. John T. Couvillion received his medical degree and ophthalmology specialty training at Tulane University School of Medicine in New Orleans, Louisiana. He then completed a two-year vitreo-retinal surgical fellowship at the renowned Cullen Eye Institute at Baylor College of Medicine in Houston, Texas. Dr. Couvillion was also granted a scholarship for additional training in Uveitis at McGill University in Montreal, Canada.

Following in his father's footsteps, in 1999 Dr. Couvillion established his own private practice devoted to the diagnosis and treatment of retinal diseases. Dr. Couvillion enjoys sharing his expertise with his patients. Raised in California, Dr. Couvillion and his family are proud to be amongst his family roots in south Louisiana.


Dr. Barbara A. Noguchi is a board certified ophthalmologist and New Orleans native. She graduated from high school and college in California before returning to Louisiana where she earned her medical degree and completed her ophthalmology residency, both from Tulane University School of Medicine. Dr. Noguchi completed a vitreoretinal fellowship at the Ochsner Clinic in New Orleans and went on to establish a large retinal practice there. She has also worked in private practice, several VA hospitals in the state of Louisiana, and at the Tulane University Department of Ophthalmology.

Dr. Noguchi is delighted to be working in Baton Rouge at Retina & Vitreous of Louisiana. Here she has found a wonderful fit for her to practice medical retina with the care and integrity that is so important to her.
