Dr. Nicolaas P. DeRuyter is a vitreoretinal surgeon with interests in advanced imaging and modern techniques for complex retinal disease. He cares for patients with age-related macular degeneration, diabetic eye disease, retinal vein occlusions, epiretinal membranes, macular holes, and retinal detachments, and also manages challenging lens-related problems. Dr. DeRuyter has a special interest in pediatric vitreoretinal conditions, including retinopathy of prematurity and inherited disorders, and works closely with families to guide timely care. Originally from the Yakima Valley, Dr. DeRuyter completed medical school at the University of Washington, ophthalmology residency at the Vanderbilt Eye Institute—where he served as chief resident—and a surgical retina fellowship at Vanderbilt. He is board-certified and excited to serve patients across Pacific Northwest Retina’s Seattle-area locations with clear explanations, coordinated care, and treatment plans tailored to each patient’s needs.

Dr. Avni Finn is a retina specialist at Vanderbilt University Medical Center with clinical and research interests focused on vitreoretinal diseases and surgery. She cares for patients with a wide range of retinal conditions and is committed to bringing advanced imaging and surgical innovation into everyday care. Dr. Finn’s work includes macular degeneration and other disorders that affect the retina’s structure and function. She has particular expertise in macular hole surgery and the use of intraoperative OCT imaging to guide delicate retinal procedures. Her research explores imaging-based biomarkers of retinal atrophy and scarring, along with retinal image analysis to improve decision-making and outcomes. She completed ophthalmology residency training at Massachusetts Eye and Ear/Harvard Medical School and a fellowship in vitreoretinal diseases and surgery at Duke Eye Center, and she also holds an MBA from the Tuck School of Business.

Dr. Jeffrey J. Mattingly is a cataract and glaucoma surgeon at Vanderbilt Eye Institute. He partners with patients to create practical, personalized plans--ranging from optimized drops and laser treatments to advanced cataract surgery and MIGS--to protect vision and maintain day-to-day independence. In the operating room, he offers traditional and laser-assisted cataract surgery with a range of intraocular lens options, and he performs laser and incisional procedures for glaucoma when indicated. Dr. Mattingly completed medical school and residency training before a glaucoma fellowship at the University of Miami's Bascom Palmer Eye Institute. Patients appreciate his clear explanations, attention to detail, and collaborative style. Whether evaluating a new glaucoma suspect, fine-tuning pressures after surgery, or planning cataract surgery to improve clarity, he focuses on outcomes that matter to patients and their families.
