Fluorescein Angiography Imaging
Conditions
Brief summary
Comparisons for vascular structure visualization in the retina and choroid.
Interventions
The Topcon DRI OCT Triton with SS-OCT Angio software is an OCT with a fundus camera used for diagnostic purposes
The Zeiss Cirrus HD-OCT 5000 is an OCT used for diagnostic purposes
The TRC-50DX retinal camera images the fundus used for diagnostic purposes

Exclusion criteria
1. Subjects unable to tolerate ophthalmic imaging 2. Subjects with ocular media not sufficiently clear to obtain acceptable OCT-A scans 3.

Concomitant use of hydroxychloroquine or chloroquine 7. Subjects where the study eye was treated after screening and before imaging RETINAL GROUP Inclusion Criteria 1. Subjects 22 years of age or older on the date of informed consent 2. Subjects able to understand the written informed consent and willing to participate as evidenced by signing the informed consent 3. Subjects who have not participated in the DRI OCT Triton with SS OCT Angio software Evaluation Prestudy 4. BCVA 20/400 or better in the study eye 5. Diagnosis of some type of retinal pathology likely to present in the vasculature in at least one eye as determined by the investigator, may include, but is not limited to: Diabetic retinopathy, Retinal Vein occlusions, Exudative AMD or Macular telangiectasia with expected presentation in the vasculature of, including but not limited to, microaneurysms, capillary dropout and/or choroidal neovascularization.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Positive percent agreement (PPA) for each OCT-A device using TRC-50DX as the reference | Day 1 | Comparison of OCT devices to TRC-50DX |
| Negative percent agreement (NPA) for each OCT-A device using TRC-50DX as the reference | Day 1 | Comparison of OCT devices to TRC-50DX |
| Agreement of pathology identification between the two OCT-A devices | Day 1 | Compare the pathology identifications between the OCT-A devices |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| OCT-A image quality score (poor, average and good) | Day 1 | Image quality score |
