All About Optical Coherence Tomography (OCT) Imaging

What Is It?

A non-invasive imaging examination that employs light waves to snap cross-section representations of the retina, OCT is employed successfully by ophthalmologists everyday.

Using this method, eye doctors can map and assess the thickness of each distinctive layer of the retina: the light-sensitive tissue that covers the rearmost part of the eye. These determinations allow them to diagnose and develop a treatment plan for retinal diseases and glaucoma.

Prior to the OCT exam, your ophthalmologist may insert diluting eye drops with the goal of widening your pupil and assisting with retinal assessment. You will sit directly in front of the machine doing the optical coherence tomography with your head supported so that it remains motionless.

The mechanism will scan your eye, without making physical contact, for approximately five to ten minutes. If pupil dilation occurred, your eyes may be light sensitive for several hours following the exam.

What Are the Associated Conditions?

A number of eye conditions can be diagnosed using optical coherence tomography. These include:

  • Glaucoma
  • Age-related macular degeneration
  • Preretinal membranes
  • Macular pucker
  • Macular hole
  • Macular edema
  • Central serous retinopathy
  • Diabetic retinopathy

Furthermore, OCT is regularly employed to assess optic nerve disorders. Consisting of a number of nerve fibers, the optic nerve transmits retinal signals to your brain, where they are interpreted as the visuals you view. The OCT test can help identify alterations to optic nerve fibers, for example those induced by glaucoma.

As OCT depends on light waves, it cannot be employed successfully in concert with any illness that conflicts with light transmitting through the eye, for example significant vitreous bleeding or dense cataracts.

Important Information About OTC Imaging:

What are the treatment plans following an OCT test?

Depending on the diagnosis that results from an OCT exam, your eye doctor will decide on the proper course of treatment.

If the diagnosis is glaucoma, next steps could include pills, eye drops, surgery, or a blend of these.

If you are found to have macular degeneration, options might involve laser therapy, anti-angiogenic medication, vitamins, or a combination of these.
