Dr Raj is passionate about educating and empowering the community on health issues. She has featured on A Current Affair to promote the need for diligence in monitoring chronic eye disease, and is a regular contributor to promotional material used to launch the annual Macular Degeneration Awareness Week campaign.

Dr Raj continues to be an ambassador for Vision Australia, a not-for-profit organisation devoted to caring for vision-impaired individuals. She has pioneered several hospital and community programs that educate the community about Vision Australia services, and is a benevolent supporter of Vision Australia's Carols by Candlelight.

Her philanthropic work in the area of indigenous eye health is remarkable. Having worked in indigenous communities throughout her medical training, she now partners with not-for-profit teams to investigate how to deliver outreach services to these communities.

Dr Raj’s early research with investigators at the Save Sight Institute in New South Wales looked at pathological processes of drusen that led to the irreversible sequelae in age-related macular degeneration. This research contributed to the understanding of this disease process, and has been instrumental in determining how the disease is managed today. Today, she dedicates much of her clinical time to investigating the pathological processes behind other retinal diseases, in particular, diabetic retinopathy.

Dr Raj is currently involved in clinical trials investigating outcomes of patients presenting with cataract and diabetic retinopathy. She is also an affiliate of Professor Wilson Berka’s clinical research group looking at complications of diabetic retinopathy, The Baker IDI and The University of Melbourne. She has co-authored a chapter on diabetic retinopathy in a renowned medical textbook – Textbook of Vascular Disease, Elsevier Press.

In the area of cataract surgery, Dr Raj’s work focuses on the impact of cataract surgery for predisposed individuals with retinal disease. She is also currently investigating refractive outcomes of patients with high myopia, focusing on refractive options and retinal changes.

Dr Raj continues to co-edit and author key feature articles contributing to the Continuing Professional Development of optometrists in the ophthalmic magazine, Mivision.

Through her role as a RANZCO clinical tutor and examiner for ophthalmology trainees, she is presently conducting an audit into surgical training and looking at ways in which this can be enhanced through the use of web-based technology.
