Optical Coherence Tomography in Glaucoma
The optic disk and the RNFL are the principal sites of apparent glaucomatous damage which precedes glaucomatous visual field alterations. RNFL defects are known to precede detection of visual field defects by approximately 6 years. Accurate early detection and monitoring of ONH and RNFL defects has become the prime focus of effective management of glaucoma. Optical coherence tomography employs ...
متن کامل[Anterior segment optical coherence tomography in glaucoma].
In recent years, the rapid development of diagnostic optic devices has generated optical coherence tomography (OCT) as a new, non-invasive diagnostic method. With technical progress of the infrared spectrum at 1,310 nm, OCT of the anterior segment also became feasible. With anterior segment OCT different examinations which so far were ruled out by ultrasound in contact manner could be executed ...
متن کاملOptical coherence tomography angiography in glaucoma : a
The advent of optical coherence tomography angiography (OCT-A) provides a new opportunity to visualize the retinal vasculature in a non-invasive and dye-free manner which may help identify vascular abnormalities in glaucoma. While a reduction in retinal and optic nerve head vessel densities and blood flow indexes measured by OCT-A has been demonstrated in patients with glaucoma in many studies,...
متن کاملCirrus high-definition optical coherence tomography compared with Stratus optical coherence tomography in glaucoma diagnosis.
PURPOSE To compare the retinal nerve fiber layer (RNFL) evaluation using Cirrus optical coherence tomography (OCT) and Stratus OCT in glaucoma diagnosis. METHODS One hundred thirty normal and 86 patients with glaucoma were included in this prospective study. The signal strengths of the OCTs were evaluated. The sensitivities and specificities of global RNFL average thickness were compared in t...
متن کاملClinical Applications of Optical Coherence Tomography in Ophthalmology
Assessment of the peripapillary nerve fiber layer and macular thickness can be determined in ophthalmology using optical coherence tomography (OCT). Decreased nerve fiber layer thickness and macular ganglion cell thickness in optic nerve ischemia have been correlated with visual field loss. OCT allows deep optic nerve head evaluation which helps understand pathophysiology of diseases. Furtherm...
