1. A new way to see abnormal blood vessels in AMD
Callum Narita – Honours student

2. Neovascular - “wet” AMD

3. Treatment Injection of anti-VEGF into eye
Early treatment leads to better outcomes

4. Optical coherence tomography
Cross-sectional view of the eye
We can see fluid from wet AMD
We can’t see the vessels that are leaking

5. Dye angiography Dye through cannula in arm
Can see leaky blood vessels at the back of the eye (“wet” AMD)
But we don’t like to give dye to everyone

6. OCT angiography
Non-invasive view of the vessels at the back of the eye
Can see particular layers
Asymptomatic new vessels
But can’t see leak
Images retrieved from Teussink MM et al. Invest Ophthalmol Vis Sci 2015;56(9):

7. Normal detection of neovascular AMD
Symptoms
Poor vision
Distorted vision
Delay
OCT or dye angiography
Visualise fluid
Treat or image further
Asymptomatic blood vessels

8. Clinical Research What can we use it for? Can see new vessels
Identify high risk patients
Clinical
Learning about vascular changes
Research

9. What can we use it for? – research
Find changes prior to neovascular AMD
Look for blood vessel changes in dry AMD
Is new vessel growth protective?
Identifying patients for clinical trials

10. Our OCTA
New technology, allowing for faster scanning and higher resolution
International research collaboration
