How OCT Technology Detects Eye Disease Before Symptoms Start

When it comes to protecting your vision, early detection is key. Many eye diseases progress silently - causing no pain or noticeable vision changes until permanent damage has already occurred. At Radiant Eye Care, we use advanced diagnostic tools like Optical Coherence Tomography (OCT) to identify signs of disease at the earliest stages, often before symptoms begin.

What Is OCT Technology?

OCT is a non-invasive imaging test that uses light waves to capture detailed cross-sectional images of the retina. These images allow eye doctors to see the layers of the retina with incredible precision, revealing subtle changes that are invisible during a standard eye exam. By identifying these microscopic changes, OCT helps us monitor eye health over time and take action long before vision loss develops.

Diabetes and Diabetic Retinopathy

For patients with diabetes, changes in the tiny blood vessels of the retina can begin years before vision is affected. OCT can reveal early fluid leakage, swelling, or abnormal blood vessel growth - helping us start treatment early to preserve sight.

Glaucoma

Glaucoma gradually damages the optic nerve, often without noticeable warning signs. OCT measures the thickness of the nerve fiber layer and optic nerve structure, detecting damage long before you experience blind spots or vision loss.

Macular Degeneration

Age-related macular degeneration (AMD) is one of the leading causes of vision loss in older adults. OCT allows us to spot early deposits (drusen) and subtle changes in the macula, guiding us to recommend lifestyle changes, monitoring, or treatment before central vision is impaired.

Why Routine Retina Exams Are Essential 

Even if your vision feels perfectly fine, routine retina exams with OCT imaging are essential for maintaining long-term eye health. Many diseases are most treatable when caught early, and OCT helps ensure that nothing goes unnoticed. By scheduling regular comprehensive eye exams, you’re taking a proactive step to safeguard your sight.
