Corneal Topography
This computerized test maps the curve of your cornea. It can show problems with your eye’s surface, like swelling or scarring, or conditions such as astigmatism. You might have it before you have surgery, a cornea transplant, or a contact lens fitting. Fluorescein angiogram Applanation Tonometry This test measures the amount of pressure it takes to flatten a portion of your cornea. Pressure readings help your doctor diagnose and keep track of glaucoma. He’ll give you drops to numb your eye, then press lightly on it with a tool called a tonometer.
