ZEISS CIRRUS HD 4000 OCT-STRATUS III OCT

CIRRUS applications currently available for the treatment of glaucoma include RNFL, ONH and evaluation angle in addition to the new analysis of the basal ganglia (GCA). If the state ONH and RNFL are not defined, GCA can provide more information. With the imaging angle of CIRRUS and central corneal thickness measurements, you have the complete state of the art instrumentation for structural assessment of glaucoma
It allows the acquisition of high resolution images (less than 5 microns) of the retina and optic nerve, providing an amount of data and information hitherto unimaginable.
The applications of OCT (short for Optical Coherence Tomography), and in particular of the Cirrus HD-OCT are innumerable.
The examination, ultrasound with a similar principle, consists of a series of photographs taken by the reflection of infrared laser beams on the retina.
By ultrasonography is distinguished mainly because the latter uses acoustic waves, but also for the accuracy, as in this exam you arrive at a resolution equal to about 7-10 thousandths of a millimeter (nanometers).
The examination takes place without the use of drops to dilate the pupil and without the injection of contrast substances. The patient simply has to look into the lens of a camera, doing the shooting in a few moments, without any glare from the patient. The exam has a duration ranging from 5 to 10 minutes because the images are obtained in fractions of a second and the retinal map is ready soon after.
The spectral domain OCT high-resolution endeavor of modern techniques for studying the tissue of the retina.
The test is suitable for all diseases involving the macula, but is more frequently used in the following conditions:
retinal atrophy
corioretinopatie acute and chronic
age-related macular degeneration and youth with or without subretinal neovascularization
serous and hemorrhagic detachment of the retina and pigment epithelium
macular edema of various origins
macular holes and pseudori
glaucoma
injury vitreoretinal interface. Vitreoretinal traction.
epiretinal membranes intraretinal and preretinal neovascularization diabetic retinopathy
OCT (Optical Coherence Tomography) also allows you to perform early diagnosis of all retinal diseases involving the macula. It 'a non-invasive, easily repeatable, non-destructive and very accurate, which represents an important step forward in the field of preventive medicine.
The apparatus used in our study Ophthalmology is the latest generation of high-definition (Carl Zeiss Meditec Cirrus HD-OCT) and allows, in addition to the study of the macular area, also the irido-corneal angle display and study of the Papilla Optics with assessment of nerve fibers.
