ENLARGE TEXT

Optical Coherence Tomography, or OCT, is a laser-based, noncontact, noninvasive imaging technique that is capable of obtaining high-resolution images of the retina and its components.

 

OCT is analogous to ultrasound imaging except that light rather than sound waves is used, resulting in a much higher resolution of approximately 10µm in the retina. OCT provides direct, real-time, cross-sectional images of retinal tissue layers, allowing improved resolution and diagnostic capabilities of a variety of eye diseases.

  • RPE: Retinal Pigment Epithelium
  • ILM: Inner Limiting Membrane
  • CC: Choriocapillaris

  • GCL: Ganglion Cell Layer
  • IPL: Inner Plexiform Layer
  • IS/IOS: Inner & Outer Photoreceptor Segment Junction
  • OPL: Outer Plexiform LayerLorem Ipsum

OCT has been shown to be clinically useful for imaging and directly visualizing selected macular diseases including macular holes, macular edema, age-related macular degeneration, central serous chorioretinopathy, epiretinal membranes, schisis cavities associated with optic disc pits, and retinal inflammatory diseases.

Diabetic Macular Edema
Analysis of diabetic macular edema reveals thickening of the neurosensory retina with nonreflective cystic spaces visible in the fovea. Macular thickness is quantified; intraretinal or subretinal fluid accumulation can be monitored after treatment.
Macular Hole
A macular hole can be detected even when otherwise unseen. Quantitative information aids in staging and in evaluating surgical intervention.
Age Related Macular Degeneration
In age-related macular degeneration, geographic atrophy and other pathologic changes can be directly viewed. Measurements of retinal thickness provide an objective means of monitoring edema and subretinal fluid.

  • My first eye exam at Boulder Eye Surgeons was very thorough and informative. The technician that gave the eye exam was very friendly and explained exactly what was going on behind these blue peepers regarding my far sightedness! Dr. Keller is my favorite eye doctor and I would recommend him for any serious eye difficulty.

    - Charles C.

  • Pre and post cataract surgery followup with BES staff was excellent. All staff members were very knowledgeable and efficient as I called several times with questions. Surgery with Dr. Cuevas was excellent and I am very happy so far with results. Dr. Cuevas was clear and transparent with answers to my post-surgery questions and spent substantial time with me pre-surgery to make sure we came up with the best solution to meet my athletic vision requirements. I highly recommend Boulder Eye Surgeons.

    - Michael L.

  • The professionalism of the entire staff is impressive. Dr. Nichols spent adequate time with me explaining everything thoroughly. My daughter came with me and he took the time to address her concerns and answer her questions. The Optical department is just as 5 star as the rest of the practice. I am so grateful to these people for how they are addressing my problems with my eyes which involve a complex medical condition.
