Optical Coherence Tomography in Glaucoma Diagnosis and Monitoring
Understanding Optical Coherence Tomography
Optical Coherence Tomography uses light to create detailed pictures of the layers inside your eye, offering a clear view of structures that are invisible during a routine exam.
This high tech scanner is a critical tool for our glaucoma specialists when assessing retinal health and diagnosing early signs of eye disease.
Imagine a camera that can look inside your eye, layer by layer, to spot even the smallest changes before they affect your vision.
OCT quickly identifies abnormalities that might otherwise go unnoticed, allowing for prompt treatment and better outcomes.
How the OCT Scanner Works
An OCT scanner uses light waves to capture images of your eye’s interior layers, much like an optical ultrasound that relies on light instead of sound.
Traditional imaging relies on photographs or sound waves, but OCT reflects light within the eye to build detailed images of tissue structure.
During the scan, light bounces off different layers of your eye, and the returning light constructs a map that highlights variations in tissue density.
Brighter areas show denser layers such as the retinal nerve fiber layer, while darker areas reveal less reflective tissues like the vitreous gel, all captured in seconds without discomfort.
Monitoring Progressive Eye Conditions
Routine OCT scans are essential for patients managing chronic eye conditions, providing a clear record of changes over time.
Glaucoma causes gradual retinal changes, and OCT helps us follow these alterations closely to protect your sight.
OCT shows whether medications, laser therapy, or surgery are effectively stabilizing or improving your condition.
Consistent imaging alerts our team to subtle shifts before they impact daily life, supporting timely adjustments in care.
Types of OCT Technology
Advancements in OCT technology provide greater speed and image clarity, giving us more information to guide your treatment.
The earliest OCT version offers helpful images, though slower speed and lower resolution may miss very fine details.
This common technology is faster and sharper, minimizing motion artifacts and delivering highly accurate images.
The most advanced form captures images rapidly and reveals deeper layers such as the choroid, ideal for complex cases.
What to Expect During an OCT Scan
OCT scans are quick, painless, and require no contact with your eye, making the experience comfortable and stress free.
You will sit with your chin on a support, and your pupils may be dilated to improve visibility of internal structures.
Looking straight ahead, you will notice a soft light as the device aligns itself for imaging.
The scanner glides across your eye, capturing cross sectional images within seconds, often before you realize it.
Our glaucoma specialists examine the images right away and explain any findings so you understand your eye health.
Key Imaging Terminology
Understanding the language of OCT helps you follow along as we discuss your results.
This layer carries visual signals to the brain, and thinning here is an early indicator of glaucoma.
The RPE nourishes and supports the retina, and OCT can reveal degenerative changes or abnormalities in this layer.
The blood vessel rich choroid supplies nutrients to the retina, and advanced OCT techniques visualize it clearly.
These photoreceptor layers are important for sharp vision, and OCT highlights any disruptions that could affect sight.
Diagnosing Eye Conditions
OCT offers exceptional clarity when diagnosing many retinal and macular conditions that other tests may overlook.
OCT illustrates how the vitreous gel pulls on the retina, helping us decide if intervention is needed.
Detailed imaging shows the size and depth of a macular hole, guiding decisions about surgical repair.
A thin, shiny layer of scar tissue becomes visible on OCT, allowing us to assess its effect on your vision.
Fluid pockets appear as dark spaces on OCT, signaling swelling that may require prompt treatment.
OCT reveals a smooth dome shaped elevation under the retina, characteristic of CSCR.
Yellow deposits linked to diabetic retinopathy stand out on OCT, enabling close monitoring over time.
White patches that indicate nerve fiber swelling are easily distinguished from other retinal changes on OCT.
Small deposits beneath the retina signal early macular degeneration, and OCT tracks their size and spread.
OCT confirms the benign nature of this thickened RPE layer and rules out more serious problems.
This mole like spot inside the eye is measured with OCT to ensure it remains stable.
Supporting Early Detection
Good eye care habits complement OCT imaging and keep your eyes comfortable, especially if you wear specialty lenses.
Following these steps helps maintain clear vision and reduces irritation.
- Use preservative free saline to fill scleral lenses and protect the tear reservoir.
- Clean lenses every day with a solution compatible with highly oxygen permeable materials.
- Store lenses in a clean case dedicated to them, and replace lenses as directed.
- Attend regular follow up visits so we can confirm lens fit and address any concerns early.

I've never been to an eye doctor and felt so comfortable! As soon as I walked in I was greeted by the friendly staff. Everything was recently renovated and it looks amazing! Definitely will be back!

I wanted to express my deepest gratitude for the remarkable care and expertise Dr. Garrana provided during my PRK surgery with cross-linking. Her skills and dedication have truly changed my life in ways I never thought possible. Thanks to the exceptional treatment, my vision has been transformed.
