As Associate Director of The Vision Center and Chief of the Pediatric Ophthalmology Service, Dr. Sudha Nallasamy oversees operational aspects of the division and is intricately involved in the growth of the pediatric ophthalmology service line.

After completing her fellowship in pediatric ophthalmology and adult strabismus at Boston Children’s Hospital, she spent two years on faculty at University of Michigan/ Kellogg Eye Center, further sharpening her skills in complex strabismus surgery, prior to joining The Vision Center at CHLA.  Dr. Nallasamy joined CHLA in 2012 and has been a cornerstone of the clinical and surgical education of USC ophthalmology residents in pediatric ophthalmology. Her keen interest in education and inspiring interest in the field of pediatric ophthalmology led to the development of a USC medical student rotation in Pediatric Ophthalmology at CHLA.

Clinically, Dr. Nallasamy treats a broad range of pediatric eye conditions, with a focus on complex pediatric and adult strabismus.

Dr. Nallasamy’s research focuses on pioneering a real-time telemedicine model for pediatric ophthalmology to improve access to specialized ophthalmic care. She has also created an educational video series entitled “All Eyes Here” and is studying “edutainment” to teach strabismus and inspire interest in pediatric ophthalmology. She is on the Clinical Advisory Board for the West Coast Consortium for Technology & Innovation in Pediatrics and is an active member of the American Association of Pediatric Ophthalmology and Strabismus, the American Academy of Ophthalmology, and Women in Ophthalmology.
