Neovascular (Wet) Age-related Macular Degeneration (AMD)NCT02253030
OCT Angiography in Wet AMD
An observational study of Neovascular (Wet) Age-related Macular Degeneration (AMD), run by Oregon Health and Science University at 1 site in United States.
Trial summary
The primary goals of this study are to use optical coherence tomography (OCT) angiography (blood vessel mapping) to: 1. diagnose the presence of new blood vessels in wet age-related macular degeneration (AMD) 2. evaluate patients undergoing treatment for wet AMD 3. Read more about this study

About this study
Official title: Optical Coherence Tomography Angiography in Neovascular Age-related Macular Degeneration
The primary goals of this study are to use optical coherence tomography (OCT) angiography (blood vessel mapping) to:
- diagnose the presence of new blood vessels in wet age-related macular degeneration (AMD)
- evaluate patients undergoing treatment for wet AMD
- determine if reduced flow to the choroid is a risk factor for developing wet AMD.
- Being tested
- Optical Coherence Tomography
- Keywords
- AMD, OCT, Angiography, Macular degeneration
- Medical subject headings
- Macular Degeneration
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Optical Coherence TomographyDevice
| Study group | Role | What they receive |
|---|---|---|
| Newly-diagnosed, untreated wet AMD | This group will be adults newly diagnosed with wet AMD who have not undergone any treatment for the condition. Their data will be gathered only once, prior to treatment. Receives: Device: Optical Coherence Tomography | |
| Wet AMD undergoing "as-needed" treatment | This group will be adults undergoing treatment as-needed for wet AMD. They will be followed monthly over the course of 1 year. Receives: Device: Optical Coherence Tomography | |
| High-risk eyes | This group will be adults with wet AMD in one eye and findings of dry AMD in the other. The eye with dry AMD will be followed every 6 months for 3 years. Receives: Device: Optical Coherence Tomography | |
| Wet AMD undergoing a "treat and extend" strategy | This group will be adults with wet AMD undergoing treatment under the "treat and extend" strategy. (The "treat and extend" strategy increases the intervals between treatments as long as the macula remains dry.) They will be followed over the course of 1 year with extra imaging before extending follow-up intervals. Receives: Device: Optical Coherence Tomography |
