Research Interests
Dr. McLellan’s main area of research focus is glaucoma, including imaging of the retina and optic nerve, electrophysiology, aqueous humor dynamics, and the genetics and pathology of glaucoma. Dr McLellan has identified a pedigree of cats with a spontaneous, recessively inherited form of congenital glaucoma that is caused by mutation in a gene that is also responsible for an identical spectrum of pediatric glaucoma in children. Her highly collaborative laboratory continues to examine structure/function correlations in these animals including the role of TGF beta signaling and ocular biomechanics on individual susceptibility to vision loss due to glaucoma. Her goal is to identify new treatments for this disabling disease in humans and animals.

     Dr. McLellan is program director for a shared, NIH-funded instrument for multimodal imaging of ocular tissues in vivo. This core resource encourages and facilitates non-invasive longitudinal studies in a wide range of species, limiting the number of animals needed for vision research studies.

     Dr McLellan also has a strong research interest in comparative ophthalmic pathology and has co-authored a textbook on the subject. She is a member, and immediate Past President, of the Executive Committee of the European College of Veterinary Ophthalmologists, serves on the Editorial Board of the journal "Veterinary Ophthalmology" and is a Trainer in the Comparative Biomedical Sciences graduate program at UW Madison.
