Fluorescein angiography (OCT) is an office procedure which involves injection of a dye called fluorescein into the bloodstream then photographing the movement of the dye through the retina. This test can provide valuable information to diagnose and guide treatment for many diseases including diabetic retinopathy, age-related macular degeneration (AMD), retinal vein occlusion, and many inherited conditions. The most common adverse effect is a transient feeling of nausea, which occurs in about 10% of patients. This dye is not related to other dyes used in MRI, CT, or IVP testing. Allergies to this dye are not common but can occur. For more information, please visit: https://www.aao.org/bcscsnippetdetail.aspx?id=429f2356-bb01-42a0-a845-6a535e98d9cf.
Optical Coherence Tomography
Optical Coherence Tomography is a non-invasive imaging test performed in the office. Microscopic detail of the layers of the retina can be seen providing information helpful to guiding treatment of many macular diseases including macular edema, macular pucker, macular holes, and age-related macular degeneration. Light waves are reflected from the retina and analyzed to create this very detailed image. Our offices use the most advanced type of OCT imaging.

As with other specialties, ophthalmologists can use ultrasound to study the structure of the eye. Often called B-scan, this is typically used when the view to the back of the eye is not clear, such as with vitreous hemorrhage, corneal scarring, or a dense cataract. This test is also used to better evaluate and measure tumors in the eye. This test is performed through the eyelid in the office. No anesthesia is needed and there is no pain with this procedure.

Macular Perimetry is a type of visual field testing that measures your ability to see points of light at or near your center of vision. This is a relatively quick test that will provide a map of your macular sensitivity and will reveal areas that are not functioning properly. This test is very helpful in following progression of certain macular diseases such as macular degeneration and diabetic retinopathy. Our office uses the Nidek MP-3.
