Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To develop a database of the peripheral choroidal circulation using ultra widefield (UWF) imaging. This database will serve as a quantitative reference tool for the comparison of subjects to a database of known normal subjects.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Subjects older than 20 years old with good general health.
* Subject is capable of giving consent.
* The subject is able and willing to comply with the study procedures.
* Subjects with ocular media clear enough to allow good quality ocular imaging.
* Normal subjects with no known retinal or choroidal disease.

Exclusion Criteria

* Subjects under 20 years old.
* Subjects with contraindications to dilation.
* Subjects with a history of epilepsy.
* Subjects with a known allergy to iodine, shellfish or intra-venous x-ray contrast dyes.
* Subjects who are or who may be pregnant.
* Subjects with past history of any vitreoretinal disease or surgery such as retinal detachment, epiretinal membrane, or vitreous hemorrhage.
* Subjects with any ocular condition that interferes with good quality image acquisition, such as corneal opacities, cataract, and dense vitreous hemorrhage.
* Subjects with any evidence of any retinal or optic nerve disease including glaucoma.
* Subjects with any anterior segment disease with the exception of common ocular surface disorders (blepharitis, dry eye).
* Subjects with medical conditions that interfere with the subject's compliance to study procedures such as inability of the subject to maintain steady head or eye positioning as in patients of ataxia or nystagmus.
* Subjects with a history of Diabetes, uncontrolled blood pressure (defined as systolic \>/= 160mmHg and/or diastolic \>/= 90 mmHg), and Vascular Disease (cardiovascular, peripheral vascular, or cerebrovascular).
