30 Aug A LOOK INTO OUR EYE CARE TECHNOLOGY
At our clinic, we utilize the latest in eye care technology to better help our patients. Our goal is to detect eye diseases or any other problems quicker and in a more efficient manner. If you’re interested in the technology we use, the following is a list of some of the equipment we have in our clinic. The machines are technical in nature, so we’ll let you know what they’re used for in both laymen’s and technical terms.
CIRRUS HD-OCT 500
WHAT IT DOES
The CIRRUS HD-OCT 500 is able to find retinal diseases in an easy way while using the least amount of time. It can map out your retinal condition for easy viewing.
With the new FastTrac retinal tracking system, precise macular thickness analyses, detailed layer maps and more than 100 B-scans at its disposal, CIRRUS provides the framework to effectively assess our patient’s retinal condition. CIRRUS data cubes are registered with data from prior visits after the scan is complete. This allows us to view each portrait from each of your visits side by side. CIRRUS compares measurements from the current and prior visits to provide a thickness change map that helps you determine what to do next. Click here for more information.
Glaucoma is one of the many diseases that we can detect with this technology. With CIRRUS angle imaging and central corneal thickness measurements, we have an outstanding tool for glaucoma structural assessment. Guided Progression Analysis™ (GPA) provides a powerful tool for determining change for Retinal Nerve Fiber Layer and optic nerve head parameters.
NM-1000 NIDEK CAMERA
WHAT IT DOES
The NM-1000 Nidek Camera is used for digital imaging for many diseases. It offers direct, digital-to-digital data management so the quality of images being produced doesn’t drop, which ultimately creates better images for analysis.
A few of the optical issues the machine can detect are: diabetes, glaucoma, and other retinal diseases. The NM-1000 Fundus Camera provides high-resolution megapixel 45-degree images by incorporating a new Digital Progressive Scan CCD camera. Unlike other Fundus cameras that convert digital signal into data for storage, this machine is extremely easy to use and comfortable for patients: with infrared light, the internal fixation target, patient data, photographed data and other setup information can be displayed for maximum convenience.
HUMPHREY VISUAL FIELD (HVF)
WHAT IT DOES
The Humphrey Visual Field is an industry standard test which allows our staff to look for problems in the sensitivity of the eye. For example, the central vision of the eye may be good, but the periphery of the visual field may be seriously damaged.
It is important to detect changes in the visual field in order to maintain the function of the eye. As a good eye is able to make up for poor vision in the other eye, the effects of visual field damage are often unnoticed by the patient until there is a large amount of damage done to their vision. The Humphrey visual field test is designed to pick up the earliest changes to the function of the eye. The Humphrey Visual Field Analyzer has become an industry standard machine for the diagnosis of glaucoma and other ocular and neurological diseases.
NIDEK ARK-530A AUTOREFRACTOR
WHAT IT IS
Like the other pieces of equipment mentioned above, the Nidek ARK 530A is used to measure patients with eye problems. This includes: cataracts, corneal opacities, IOLs, and post LASIK examinations. It takes the measurements of refractive errors of the optical centre, in terms of the sphere, cylinder and axis, in addition to the corneal curvature radius and orientation. It takes a full image to determine the shape of your eyes.
From a more technical perspective, the machine also utilizes Zonal Ring Image Method combined with the most sensitive CCD. The ARK-530A is fully automated with aligning, tracking, and focusing on the patients eyes which insures the most reliable and repeatable data. The ARK-530A allows the user to take keratometric measurements including sagittal radius and eccentricity. These measurements are used in corneal evaluations for contact lens fitting and refractive surgery evaluations.
HRT (HEIDELBERG RETINAL TOMOGRAPHY)
WHAT IT DOES
In laymen’s terms, the HRT allows for computer imaging technology to allow for the imaging of the sensitive nerve-fiber layer of the optic nerve by creating a three-dimensional view.
Heidelberg Retinal Tomography is used by our staff to observe and document information on the optic nerve head. This is essential for the diagnosis and management of the disease glaucoma. The HRT uses a special laser to take 3D photographs of the optic nerve and surrounding retina. This laser, which does not harm the eye, is focused on the surface of the optic nerve and takes the picture. The HRT takes images of deeper layers until the point desired has been reached. Finally, the instrument takes these pictures of the layers and puts them together to form a 3D image of the entire optic nerve. The HRT image can be used to calculate things such as the area of the optic disc, the volume of the cup, and the area of the rim around the cup.
DOES THAT HELP?
In conclusion, this proves that at our clinic, we have the best technology to help us diagnose your eyes to the fullest extent possible. Although highly technical, our state of the art equipment is designed to provide you with the best results in the most comfortable manner. If you have any problems with your eyes, come to Dr. D’Orio’s clinic for an eye assessment by our optometrists that prioritize your optical healthcare. Also, if you have any further questions about our technology, please feel free to ask or email us.
