At Fedorov Restore Vision Clinic, we are dedicated to diagnosing eye conditions and improving patients’ vision using the latest advancements in eye care technology. One of the most exciting advancements we offer is Optical Coherence Tomography Angiography (OCTA), a cutting-edge, non-invasive imaging technique. OCTA provides detailed, three-dimensional imaging of the eye’s blood vessels, enabling the early detection of eye diseases with remarkable precision.
Unlike traditional imaging methods, OCTA does not require dye injections or invasive procedures. Instead, it uses laser light to scan your eyes quickly and painlessly, producing high-resolution images of the retinal and optic nerve vasculature. This cutting-edge technology enables us to diagnose and monitor conditions like glaucoma, diabetic retinopathy, and age-related macular degeneration earlier than ever before, giving us the opportunity to intervene and protect your vision before irreversible damage occurs.
Beyond early detection, OCTA is invaluable for long-term monitoring. Its non-invasive nature makes it safe for frequent use, and its high-resolution, three-dimensional imaging allows us to track subtle changes over time. By combining this advanced technology with personalized treatment plans, we can intervene earlier, improve outcomes, and provide the best care possible.
Why Early Detection Matters The earlier glaucoma is detected, the better the chances of preserving vision. Traditional VF tests and optic nerve assessments may only identify the disease after significant damage has occurred. With OCTA, our clinic can catch glaucoma in its earliest stages—before symptoms develop—ensuring timely intervention and better outcomes.
One of the most transformative benefits of OCTA lies in its ability to detect glaucoma early. Known as the “silent thief of sight,” glaucoma often progresses without symptoms until significant vision loss has occurred. Traditional detection methods, like visual field (VF) tests and optic nerve exams, may miss the earliest signs of the disease. OCTA changes this by identifying subtle vascular changes in the retina and optic nerve head—such as reduced blood flow, capillary dropout, and lower vascular density—before structural or functional damage becomes visible.
The earlier glaucoma is detected, the better the chances of preserving vision. Traditional VF tests and optic nerve assessments may only identify the disease after significant damage has occurred. With OCTA, our clinic can catch glaucoma in its earliest stages—before symptoms develop—ensuring timely intervention and better outcomes.
OCTA changes this narrative. It identifies early-stage glaucoma by detecting subtle vascular changes in the retina and optic nerve head, such as:
• Reduced blood flow
• Capillary dropout
• Lower vascular density
These changes occur before structural damage or vision loss becomes apparent, allowing for timely intervention and better outcomes. Early detection not only improves the chances of preserving vision but also helps us create tailored treatment plans that adapt to your specific needs.
How OCTA Excels in Glaucoma Detection
OCTA is unique in its ability to identify microvascular changes that traditional imaging methods often miss. Key capabilities include:
• Reduced Blood Flow Detection: OCTA highlights decreases in blood supply to the optic nerve head, an early marker of glaucoma.
• Capillary Dropout Identification: Subtle gaps in the vascular network can indicate early glaucomatous damage.
• Layer-Specific Imaging: Detailed scans of the radial peripapillary capillaries and deep capillary plexuses allow us to focus on the most affected regions.
In addition, OCTA provides quantitative metrics, such as vessel density and perfusion indices, which enable precise monitoring of glaucoma progression. Even in patients with normal visual field tests, OCTA can reveal early signs of vascular changes, providing a critical early warning system.
The Advantages of OCTA in Glaucoma Care Compared to traditional imaging methods, OCTA offers significant advantages:
1. Non-Invasive and Safe: No need for dye injections or invasive procedures, making it suitable for frequent monitoring.
2. Early Detection: Identifies vascular changes well before structural or functional damage occurs.
3. High-Resolution Imaging: Provides unparalleled detail of the eye’s vascular structures in three dimensions.
4. Repeatability: Its safety and ease of use allow for consistent monitoring over time.
By integrating OCTA into glaucoma care, we can diagnose earlier, monitor more effectively, and tailor treatments to each patient’s unique condition.
What OCTA Images Reveal
To illustrate the power of OCTA, consider these two scans:
• Healthy Right Eye: The image shows a dense, well-organized vascular network surrounding the optic nerve. This structure ensures adequate blood flow and nourishment, critical for maintaining clear vision.
• Eye Left Eye with Glaucoma: In this image, capillary dropout (right corner, top) and reduced vascular density are visible around the optic nerve. These subtle changes indicate reduced blood flow and early optic nerve damage, often before the patient experiences symptoms.
These examples demonstrate how OCTA provides critical insights that help us detect glaucoma at its earliest stages, long before traditional methods reveal abnormalities.
Expanding the Understanding of Glaucoma: Linking Optic Neuropathy and Vascular Health
Glaucoma is traditionally described as a condition of elevated intraocular pressure (IOP) leading to optic nerve damage, but modern research suggests a more complex reality. Emerging evidence positions glaucoma as a Primary Vascular Optic Neuropathy, where blood supply deficiency to the optic nerve head (ONH) plays a central role in disease progression. While IOP remains a risk factor, studies highlight diminished ocular perfusion pressure (OPP) and reduced ocular blood flow (OBF) as critical contributors to ischemic injury and nerve fiber loss.
