Screening and Diagnosis

Screening and Diagnosis

To determine whether you have macular degeneration, you’ll undergo a thorough dilated eye examination. One of the things your eye doctor looks for while examining the inside of your eye is the presence of drusen and mottled pigmentation in the macula.
The eye examination includes a simple test of your central vision and may include testing with an Amsler grid. If you have macular degeneration, when you look at the grid some of the straight lines may seem faded, broken or distorted. By noting where the break or distortion occurs — usually on or near the center of the grid — your eye doctor can better determine the location and extent of your macular damage.

Angiography. To evaluate the extent of the damage from macular degeneration, your eye doctor may use fluorescein angiography. In this procedure, fluorescein dye is injected into a vein in your arm and photographs are taken of the back of the eye as the dye passes through blood vessels in your retina and choroid. Your doctor then uses these photographs to detect changes in macular pigmentation or the existence of abnormal blood vessels in your macula that may not be visible or recognizable during a standard examination.
Your doctor may also suggest a similar procedure called indocyanine green angiography. Instead of fluorescein, a dye called indocyanine green (ICG) is used. This test provides information that complements the findings obtained through fluorescein angiography.
Genetic testing- It is estimated that up to 70% of AMD risk is attributable to genetic variation. The test in done in your doctors office and is a check swab on both sides.  The patient’s AMD prognosis is presented on the first page of the Macula Risk PGx Laboratory Report. The following information is reported: Clinical information (age, smoking history, BMI and
AMD status); Genetic results (genotype for 15 AMD-associated genetic markers, and the Genetic Risk Subscore); The patient’s 2, 5 and 10-year risk of progression to
advanced AMD. AREDS personalized vitamin recommendation based on genetic results

Optical coherence tomography (OCT).This noninvasive imaging test helps identify and display areas of retinal thickening or thinning. Such changes are associated with macular degeneration. This test can also reveal the presence of abnormal fluid in and under the retina or the RPE. It’s often used to help monitor the response of the retina to macular degeneration treatments.

Optomap® Retinal Exam – Eye Exams without Dilation
The optomap® Retinal Exam provides a panoramic view of the back of a person’s eye (the retina).  The view provided by the Optomap displays over 80% of the retina.
