Diabetes - Optical Coherence Tomography (OCT)

Doctor Murphy may order fluorescein angiography or optical coherence tomography (OCT) to further evaluate your retina or to guide laser treatment if it is necessary. Fluorescein angiography 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:

  • Which blood vessels are leaking fluid;
  • How much fluid is leaking;
  • How many blood vessels are closed;
  • Whether neovascularization is beginning.

OCT is a non-invasive scanning laser that provides high-resolution images of the retina, demonstrating its thickness. OCT can provide additional information regarding the presence and severity of macular edema.

These tests help the doctor determine:

  • Why vision is blurred;
  • Whether laser treatment should be started;
  • Where to apply laser treatment.

"My experience with Dr. Murphy was very pleasant and professional. She took time to explain the problems and remedies. I had cataracts in both eyes. The lenses were replaced with multi-focal ones. I am extremely happy with the outcome. The staff was courteous, helpful and professional." James H.

"I was always so afraid to have anything done to my eyes, but Dr. Murphy's calm and full explanations took away this fear." Joan K.

"It is so nice to have a doctor responsive to my needs.  Dr. Murphy did both my cataracts and the multifocal lens enables me to read the smallest print.  I highly recommend Dr. Murphy and her staff." Bill S.
