From experimental studies we know that eyes use visual information to adjust their growth and how they are focused. My main research interest is to understand the visual signals that trigger these eye growth changes that eventually lead to myopia. In particular, I am very interested in studying the role that the peripheral retina and eye shape might have as predictors of future changes in refraction. If the periphery proves to have a significant role in the regulation of eye growth, it may be possible to manipulate peripheral optics to control myopia development, and we might be soon measuring and correcting in our clinics not only the central but also the peripheral optics of the eye.

Another of my research interests is to understand the interaction between ocular size and vascular physiology. The structural characteristics of a myopic eye include an elongated vitreous chamber, which in high myopia is related to a stretched and progressively thinned choroid and sclera. This increases the risk of choroidal and retinal changes, and a variety of other ocular diseases including macular degeneration, choroiditis and glaucoma among others. Because of the known vascular features of many of these conditions associated with pathological myopia, my research also focuses on describing the vascular changes that a non-pathological myopic eye undergoes prior to the development of posterior pole pathologies. This is of significant clinical importance, as degenerative myopia is a leading cause of blindness. In this field, I am an external collaborator with the Vascular Imaging and Research Laboratory at Aston University, Birmingham, UK to study the vascular characteristics of the eyes in patients with Alzheimer’s disease.
