Optic nerve photography

The optic nerve can appear abnormal in a number of disorders, most commonly glaucoma. A change in the appearance of the nerve over time can indicate progression or worsening of disease. In our practice we use a state-of-the-art stereoscopic fundus camera, the Nidek 3Dx®, to take accurate, repeatable, stereo-paired photographs of the optic nerve and retina. Stereo pairs allow for three-dimensional viewing, providing more detail than a standard, single-image photograph. The procedure is performed as follows:

  • Dilation IS REQUIRED for this test. If you do not like to drive with your eyes dilated, you may want to arrange for someone to drive you to the office.
  • Information, such as your name, age, and certain ocular measurements, is entered into the computer.
  • The eye not being tested may be covered with a patch.
  • Sit at the device with your forehead and chin comfortably positioned against rests.
  • The technician performing the test will give you instructions, and will ask you to look into the device at a blinking fixation target.
  • The camera will be focused and you will be asked to hold very still and to not blink for a few seconds as the photo is taken. The flash may seem very bright, but is not harmful.
  • When the test is complete you are free to go. Disposable sunshades will be provided, if necessary. Results will be mailed to you after your doctor has reviewed them, and will be discussed at your next visit.
  • This test usually takes about 30 to 50 minutes to complete, depending upon how quickly your eyes dilate.
