What are angioid streaks?
The macula is the small, specialized area of the retina that gives us our straight-ahead reading and driving vision. Angioid streaks result from an abnormal brittleness to the eyewall beneath the macula. They are often very difficult to find since they resemble the normal blood vessels that radiate out from the yellow optic nerve. The most common cause is pseudoxanthoma elasticum.
New blood vessel growth beneath the macula (macular neovascularization, MNV) can develop in some patients with angioid streaks. These vessels cause the macula to swell with fluid and blood and often lead to permanent central vision loss. There are many causes of CNV including age-related macular degeneration, choroidal rupture, degenerative myopia, idiopathic, and ocular histoplasmosis,
How are angioid streaks diagnosed?
Angioid streaks are found during a dilated retinal examination. Fluorescein angiography is often used to confirm the diagnosis and assess the severity of the retinal damage. OCT scanning is used as well to help diagnosis MNV.
How are angioid streaks treated?
Avastin, Lucentis, and Eylea belong to a new class of potent medications, VEGF inhibitors, that prevent MNV from growing and leaking. They have been extensively studied in patients with age-related macular degeneration, and are also highly effective in angioid streaks. Click here to learn more.
What happens if I lose my reading vision?
Except for airplane pilots, military personnel, surgeons, etc., most patients who lose reading vision in one eye usually continue their normal lifestyle and job without change. The major problem is adjusting to the initial lack of depth perception required for near vision. Eventually, patients learn to compensate for this and obtain new clues from the environment to judge close distances. Patients are usually able to thus gain back much of their lost depth perception. Patients should be able to drive a car as long as their vision in the good eye is at least 20/40 to 20/60.
Low Vision services and examination.
We may recommend that you see a specialist for a low vision examination. Magnifying lenses or other devices can be prescribed to help with reading and other central vision tasks.
