Research Title: The significance of corneal responses to rubbing-related ocular trauma in keratoconus
Chronic abnormal eye rubbing inflicts a form of corneal trauma that has a long-established association with the accelerated progression of keratoconus (KC). Rubbing-related corneal trauma has not yet been fully researched and attempts to reduce eye rubbing in KC patients by way of behaviour modification have had limited success. Demonstrating to patients that rubbing causes corneal trauma may be a useful approach to help motivate patients to break abnormal rubbing habits. Ocular itch is a well-known powerful rubbing provocation, so too are other factors such as rubbing induced stimulus of a pleasure centre, psychological influences for reducing stress and anxiety, as well as for relief of ocular surface dryness and other peri-orbital irritant stimuli.
Historically, clinical methods of detecting, measuring and demonstrating corneal responses to eye rubbing have been limited to basic corneal topography. Advances in the development of corneal topography, assessment of corneal densitometry, corneal pachymetry, biomechanical properties, the detection of tear film inflammatory markers, cellular responses and technological advances in corneal tomography have revolutionized the potential for the detection of corneal responses to rubbing trauma
This project will evaluate changes in corneal epithelial thickness and corneal transparency (densitometry) in normal and subjects with keratoconus who acknowledge having an ongoing habit of eye-rubbing will be invited to participate in a series of studies which aim to establish the impact of eye-rubbing on these parameters. A questionnaire has been developed to categorise the degree of eye rubbing to also examine the association with chronic ocular changes with rubbing history.
Allan is a graduate from the School of Optometry UNSW Class of 1994 and has been working in private optometric practice ever since. His rooms are in Kogarah NSW. He has also received the distinction of hosting the longest talk back eye program on Australian radio with his weekly show airing for 20 consecutive years on Sydney’s number one station 2GB. He is currently undertaking a PhD on the effects of rubbing related corneal trauma in keratoconus under the guidance of his highly esteemed supervisors and world authorities in the anterior segment; Scientia Professor Fiona Stapleton and Professor Charles McMonnies. His practice is highly regarded in the fitting and prescribing of specialty contact lenses for orthokeratology, keratoconus and complex corneal diseases. He was the first Australian optometrist with an Oculus Pentacam and has a keen passion for medical optometry. His rooms are equipped with the technology and expertise to deliver exceptional quality of eye treatments to his patients.
