Understanding Iris Tumors Using Advanced Eye Imaging
Observational Study of Iris Tumors
In Plain English
This study is watching and learning—not treating. Researchers at Oregon Health and Science University want to understand iris tumors (tumors in the colored part of your eye) better by using a special camera called OCT angiography. This camera takes detailed pictures of blood vessels in your eye and can show whether a growth is a melanoma (dark tumor) or another type of iris lesion. You won't receive any new treatment in this study. Instead, doctors will compare images from healthy eyes to images from eyes with iris tumors to figure out what patterns help identify different types of tumors. This information could help doctors diagnose iris melanomas faster and more accurately in the future.
What This Trial Does
This is an observational study using OCT angiography to assist with tumor characterization in melanotic and amelanotic iris lesions. OCT angiography data from healthy eyes will be compared to eyes with various types of iris tumors.
Who Can Join
- Inclusion Criteria for tumor group:
- Eyes with diagnosis of melanotic or amelanotic iris tumors
- Inclusion Criteria for healthy control group:
- Eyes without iris defects or lesions
- Exclusion Criteria (both groups):
- Inability to give informed consent
- Inability to maintain stable fixation for OCT imaging
- Inability to commit to required study visits
- Eyes with concurrent retinal diseases, glaucoma, or conditions that in the opinion of the investigators might affect iris circulation
- Mature cataracts if found to limit visual potential to worse than 20/40
