The optic nerve and retina cannot be repaired once damaged, which is why regular check-ups and management are essential. One of the representative methods for retinal examination is Optical Coherence Tomography (OCT), which allows for precise evaluation of the current state of the cornea, retina, choroid, and optic nerve through cross-sectional imaging. OCT plays a crucial role in the early detection of severe eye diseases by analyzing the retina and optic nerve in three dimensions. Today, let’s take a deep dive into OCT testing!
The precise principle of OCT testing.
The OCT exam, often referred to as the “CT of the eye,” is a test that uses light to meticulously observe the cross-section of the eye’s tissues. By measuring the distance based on the wavelength of light reflected from different structures, it scans the retina and optic nerve, providing high-resolution images. This allows for a more accurate assessment of the patient’s condition. OCT can detect even subtle changes that may be difficult to diagnose with just a fundus examination, as it provides 3D high-resolution images.
Eye diseases that can be detected with OCT.
The OCT is highly useful for diagnosing a variety of ophthalmic conditions by capturing detailed images of the internal structures of the eye. It is especially effective in early detection of glaucoma, macular degeneration, and diabetic retinopathy. Glaucoma causes damage to the optic nerve, macular degeneration leads to central vision loss, and diabetic retinopathy results in vascular changes, all of which can be accurately detected using OCT. This enables early diagnosis and aids in treatment planning. Additionally, OCT can identify other serious eye conditions such as retinal vein occlusion, diabetic macular edema, macular holes, macular membranes, retinal membranes, and central serous chorioretinopathy.
Q&A
Questions about OCT Testing
Q: Why is an OCT test necessary even if my vision is normal?
A: Conditions like glaucoma and diabetic retinopathy often show few symptoms in the early stages, so it’s important to have regular check-ups even if your vision seems fine. OCT testing can help detect diseases early, allowing for timely and appropriate treatment.
Q: How often should I have an OCT test?
A: If you have a family history of glaucoma or diabetes, or if you have conditions like high blood pressure or diabetes, it’s recommended to have regular check-ups every 6 months to a year.
Q: Is the OCT test painful or uncomfortable?
A: The OCT test is non-invasive and typically not painful, with very little discomfort. During the test, you’ll need to keep your eye still for a short period, and you may experience a brief bright light, but most patients find the test comfortable!
Huvitz HOCT-1/1F
Five Functions in One!
The Huvitz “HOCT-1/1F,” an all-in-one OCT, not only diagnoses various anterior and posterior segment diseases but also provides information for intraocular lens (IOL) surgery. With its powerful optical technology and innovative imaging software, it offers rapid scanning and high-quality images, enabling accurate data verification, which is beneficial for precise examinations and diagnoses.
You can conveniently perform five types of tests—3D OCT, Fundus Camera, Angiography, Biometry, and Topography—all in one place, allowing for faster and broader diagnosis of eye diseases.
The eyes are precious organs, and once damaged, recovery can be difficult. By using HOCT testing to detect major eye diseases such as glaucoma, age-related macular degeneration, and diabetic retinopathy early on, you can significantly reduce the risk of blindness! Huvitz always emphasizes the importance of “regular eye examinations” to help you take proactive care of your eye health. Your eye health is something Huvitz is dedicated to protecting! 🙂
