You may undergo tests such as the following so that your doctor can determine whether you have Fuchs' dystrophy. These tests will also measure the shape, clarity and thickness of the cornea.
July 22, 2014
- Visual test. You'll be asked to read letters and numbers on a chart to measure how well you see at various distances. This is called a visual acuity test and is a routine part of eye exams.
- Staging. Your doctor will try to determine the stage of your condition by examining your eye with an optical microscope (slit lamp). He or she will then study the cells lining the back surface of your cornea (endothelial cells). If you have irregular bumps (guttae) on the back surface of the cornea, you may have Fuchs' dystrophy.
- Corneal pressure test. Your doctor may numb your eyes with drops and then briefly touch your eye with a special instrument that measures eye pressure.
- Corneal thickness. Your doctor may use a special instrument to measure the thickness of the cornea.
- Corneal cell count. Sometimes your doctor might use another special instrument to record the number, shape and size of the cells that line the back of the cornea.
