Research

VISIT THE MCLELLAN LAB

Dr McLellan’s main area of research focus is comparative glaucoma, including imaging of the retina and optic nerve, electrophysiology, aqueous humor dynamics, genetics and pathology of glaucoma in animals and humans

Dr McLellan also has a strong research interest in Alzheimer's disease, its association with glaucoma and similarities to feline cognitive dysfunction syndrome in older cats.  More general interests include comparative ophthalmic pathology; diseases of the retina and optic nerve in dogs and cats; the ocular and systemic effects of vitamin E deficiency in dogs, and drug toxicities affecting the retina in humans and animals.
