Test for Eye Disease in Hawaii
Managing eye diseases early and correctly is the key to effective treatment. At Retina Consultants of Hawaii, we perform five diagnostic tests — fluorescein angiography, ICG angiography, optical coherence tomography, fundus photography, and ultrasound.
Fluorescein angiography (FA) is useful for diagnosing retinal or optic nerve conditions, guiding laser surgery, and tracking the course of an existing condition. Fluorescein dye is injected into the arm, and photos are taken as it makes it way through the eye. Diabetic retinopathy, macular degeneration, retinal vein occlusions, and macular edema are some of the more common disorders diagnosed with FA.
Indocyanine green angiography
Indocyanine green angiography (ICGA) is used to view choroidal (the layer behind the retina) circulation. IGCA is excellent when patients have wet age-related macular degeneration. The abnormal blood vessels that grow underneath the retina can be blocked by blood or pigment with FA, but are visible with IGCA. ICGA is essential in the diagnosis of polypoidal choroidal vasculopathy (PCV).
Optical coherence tomography
Optical coherence tomography (OCT) is a noninvasive test where a scanning light beam provides a high-resolution cross section of the retina. It is useful in analyzing retinal conditions such as macular degeneration, macular edema, macular holes, macular puckers, diabetic retinopathy, and vein occlusions.
A fundus photograph is a photographic image of the inside of the eye. The retina, optic disc, and retinal blood vessels can be viewed with a fundus photograph. Diseases such as glaucoma, retinal detachments, macular degeneration, and diabetic retinopathy can be monitored with fundus photographs.
Ultrasound uses sound waves to help visualize the back of the eye. These are the same waves used to check the fetus during pregnancy. Ultrasound provides a quick way of obtaining a clear view of the retina when either swelling, cataracts, or blood in the front of the eye is obscuring the physician’s view of the back of the eye.
