Diagnostic Imaging

Fluorescein and Indocyanin Green (ICG) Angiography

Frequently fluorescein angiography is performed to evaluate the blood vessels in the eyes for retinal disease. This study requires a small injection of vegetable dye into a vein in your arm. Sometimes a second dye is also used which is called Indocyanin Green (ICG). Serial photographs are taken of your retina through a dilated pupil. The test takes approximately 15-20 minutes. Most patients tolerate this test very well without any side effects and do not require any pre-medication. Some patients feel nauseated for a few minutes.

Autofluorescence

A digital image that looks at the health of the retinal pigmented epithelium which helps nourish the retina can become damaged in the setting of certain retinal diseases.

Optical Coherence Topography (OCT)

This is a non-invasive and non-contact retinal scan used to study the anatomy of the retina in fine detail. It requires dilation of the pupils.

Fundus Photography

High-resolution digital images of the retina is sometimes necessary to document changes in the eye because of different diseases that affect the retina. These images help us accurately monitor for any changes that may suggest worsening of your retinal eye disease. 

B-Scan Ultrasonography

This is a non-invasive imaging device for the eye which allows us to evaluate the retina when there is poor visualization by examination.
