La Computerized Optical Tomography (OCT) is a non-invasive diagnostic technique that provides detailed images of the ocular structures, particularly the retina, optic nerve, and cornea. Due to its high precision, the OCT exam has become essential for the early diagnosis and the monitoring of numerous ocular pathologiesBut what exactly does this test consist of and why is it important to perform it?
Meaning and objectives of the OCT exam
The acronym OCT stands for Optical Coherence Tomography, or Optical Coherence Tomography. This is an imaging technique that uses low-coherence light waves to obtain high-resolution scans of cross-sections of ocular tissuesIn simple terms, OCT works similarly to an ultrasound, but instead of using ultrasound, it uses light. This allows the different structures of the eye to be visualized with a microscopic precision, allowing us to identify even minimal anomalies that could escape a traditional ophthalmological examination.
The main objectives of the OCT exam are:
- Early diagnosis: identify eye diseases in their early stages, when therapies are most effective.
- Monitoring: follow the evolution of an eye disease over time and evaluate the response to treatments.
- Surgical planning: provide detailed information for planning eye surgeries, such as cataract or vitreoretinal surgery.
- Pre- and post-operative evaluation: check the condition of the ocular structures before and after surgery.
What diseases can be seen with OCT?
OCT is particularly useful for diagnosing and monitoring various eye diseases, including:
- Age-Related Macular Degeneration (AMD)OCT allows us to visualize changes in the macula, the central part of the retina responsible for clear vision, enabling early diagnosis and accurate monitoring of AMD, both in its dry and wet forms.
- GlaucomaOCT measures the thickness of retinal nerve fibers and the morphology of the optic nerve head, providing crucial information for the diagnosis and monitoring of glaucoma, even in its early stages.
- Diabetic retinopathyOCT can detect macular edema, a complication of diabetic retinopathy that causes swelling of the macula and can impair vision.
- Macular hole: OCT visualizes the presence and size of a macular hole, a lesion in the macula that causes central vision loss.
- Macular Pucker (Epiretinal Membrane): OCT identifies the presence of this membrane that forms on the surface of the retina and which can cause visual distortions.
- Vitreous Detachment: OCT can highlight the separation of the vitreous from the retina and the presence of any vitreoretinal traction.
- Optic Nerve Pathologies: OCT is useful in the diagnosis of pathologies such as optic neuritis.
How and when to perform the OCT exam
The OCT exam is Quick, painless e non-invasiveIt does not require any special preparation, although in some cases pupil dilation may be necessary, at the discretion of the ophthalmologist.
The procedure is simple: the patient sits in front of the OCT machine and is asked to focus on a bright target. The machine acquires images of the ocular structures in a few seconds. The exam it does not cause any discomfort.
The frequency of OCT testing depends on the patient's ocular condition and the ophthalmologist's recommendations. Generally, it is recommended in the presence of diagnosed ocular diseases or in cases of a family history of conditions such as glaucoma or AMD.
OCT exam preparation
- Fasting is not necessary.
- It is advisable to bring your glasses and/or contact lenses, as well as any previous eye exam reports.
- Inform your doctor of any systemic diseases or ongoing drug therapies.
