How to read OCTs: 8 fundamental diseases - EyeGuru
Full-thickness macular holes (FTMH) are very easy to diagnose with OCT. They are always a foveal, full-thickness defect that can have associated cystoid macular edema. Here, there is traction from the posterior hyaloid membrane that opens the hole in a “can opener” effect.
Optical coherence tomography imaging of macular oedema
The identification, localisation, quantification and long-term follow-up of fluid collections are the most important capabilities of OCT. Since the introduction of OCT in clinical practice, it has become an invaluable diagnostic tool and different patterns of ME have been reported.
Optical coherence tomography (OCT) for detection of macular …
OCT exams were carried out by a trained OCT technician, masked to the physician’s assessment of foveal edema, using six 6 mm radial scans. Each scan was interpreted by a second masked observer, who assessed the quality of the OCT image and recorded the retinal thickness at the centre of the macula.
Macular Edema - Patients - The American Society of Retina
Macular edema refers to an abnormal blister of fluid in the layers of the macula. From the side, it looks like the snake that ate too much. Like a droplet of water on your computer screen, the swollen retina distorts images—making it more difficult to see clearly.
What Is Optical Coherence Tomography? - American Academy of Ophthalmology
2024年9月26日 · Optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA) are non-invasive imaging tests. They use light waves to take cross-section pictures of your retina. With OCT, your ophthalmologist can see each of the retina’s distinctive layers and the optic nerve fiber layer.
Macular edema and OCT - American Academy of Ophthalmology
2024年11月19日 · Optical coherence tomography (OCT), is a more novel imaging technology that uses a laser source of light to create an optical cross section of the macula similar to ultrasonography. It is a useful technique in the diagnosis and monitoring of diabetic macular edema, especially cystoid macular edema (CME).
Diabetic Macular Edema: Diagnosis and Management
2021年5月1日 · Diabetic macular edema has overtaken proliferative diabetic retinopathy as the most common cause of vision impairment in individuals with diabetes mellitus. What you need to know.

2022年1月14日 · Clinicians frequently utilize fundus fluorescein angiography (FFA) and optical coherence tomography (OCT) for diagnostic purposes, as diagnosing macular edema clinically can be challenging in patients with mild disease or when adequate visualization of …
Optical Coherence Tomography - StatPearls - NCBI Bookshelf
2024年10月6日 · Optical coherence tomography (OCT) is a noninvasive imaging technique that uses visible and infrared electromagnetic waves to provide detailed, cross-sectional images of body tissues. OCT has widespread application in ocular imaging to diagnose and monitor various ophthalmic pathologies in both the anterior and posterior segments.
Spectral-Domain Optical Coherence Tomography for Macular Edema
2014年5月14日 · OCT is considered the best reference standard for detecting and quantifying macular edema compared to ultrasound, retinal thickness analysis, and scanning laser ophthalmoscopy [ 6, 7 ]. Compared to biomicroscopy and FA, OCT has superior sensitivity and greater resolution for detecting macular edema and subretinal fluid [ 8 – 10 ].
