Observational Study of Iris Tumors
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.
Inclusion: Eyes with diagnosis of melanotic or amelanotic iris tumors; Eyes without iris defects or lesions.
Exclusion: Eyes with concurrent retinal diseases, glaucoma, or conditions that in the opinion of the investigators might affect iris circulation; Inability to give informed consent; Inability to maintain stable fixation for OCT imaging; Inability to commit to required study visits; Mature cataracts if found to limit visual potential to worse than 20/40.
