Diagnosis of a Stroke Affecting the Eye
If you experience sudden vision loss, you should contact your ophthalmologist (Eye M.D.) immediately. He or she will conduct a thorough examination to determine if you have had a stroke involving the eye. Your Eye M.D. will dilate your eyes with dilating eyedrops, which will allow him or her to examine the retina more thoroughly for signs of damage.
Among the other tests that your ophthalmologist may conduct are:
- Fluorescein angiography. This is a diagnostic procedure that uses a special camera to take a series of photographs of the retina after a small amount of yellow dye (fluorescein) is injected into a vein in your arm. The photographs of fluorescein dye traveling throughout the retinal vessels show how many blood vessels are closed;
- Intraocular pressure (pressure inside the eye);
- Reflexes of your pupil;
- Photos of the retina;
- Slit-lamp examination;
- Testing of side vision (visual field examination); and
- Visual acuity, to determine how well you can read an eye chart.
