In assessing your glaucoma, the ophthalmologist will dilate your eyes so that he or she can get a magnified, 3D view of your optic nerve. This helps to determine the status of your optic nerves and glaucoma.
He or she will assess the shape, colour, depth, size, and vessels of the optic nerve. In order to avoid such irreversible visual debilitation, it is important to have your eyes examined for glaucoma by an ophthalmologist, especially if you carry some of the known risk factors, such as family history of the disease. It is crucial to have some basic understanding of the tests for glaucoma so that you can make an informed decision about your treatment options under the guidance of your doctor.
