Diopsys Vision Testing: Visual Evoked Potential (VEP)

Harper’s Point Eye Associates announces the addition of the Diopsys® NOVA-VEP Vision Testing System to our practice. The new vision testing system helps eye care professionals detect vision deficits, including glaucoma and other neuro-visual disorders.
Glaucoma is the second leading cause of blindness in the world, reports the World Health Organization. According to Prevent Blindness America, glaucoma is often called the "sneak thief of sight" because half of all patients who have it do not know it. Many optic nerve disorders are asymptomatic since central vision may not be affected until later stages of the disease. Also, diagnosis and management of optic nerve disorders are often based on structural or visual field tests which are limited in their ability to detect disease early.

The Diopsys® NOVA-VEP allows clinicians to objectively assess vision disorders earlier than traditional vision tests because it uses Visual Evoked Potential (VEP) technology and proprietary software to evaluate the entire vision system from the eye to the visual cortex. “VEP is an objective, functional test that can help discriminate between healthy and glaucomatous eyes,” says Alberto González García, M.D., neuro-ophthalmologist and Research Director at Diopsys, Inc., the device manufacturer. Eye care professionals may use VEP in addition to traditional testing methods to enhance diagnosis and treatment.

The Diopsys® NOVA-VEP records the electrical response of a patient’s entire vision system and provides easy-to-read reports that give the doctor a simple way to evaluate optic nerve function. Physicians are able to compare tests over time to track disease progression.

ReSeeVit Endothelium specular microscope attachment

The endothelium is the deep layer of the cornea. In a young subject it is about 5 micrometers in thickness and contains about 300,000 hexagonal cells. The endothelium is important for correct corneal function. For this reason, analysis of the endothelium is of fundamental importance for diagnosis of the health of the eye. The most important characteristic of endothelial cells is their lack of reproductive capacity. Age, surgical treatment, and use of contact lenses are factors influencing their quantity and form.

IVue Ocular Coherence Tomograph

IVue is an ultra-high speed, high resolution OCT retina scanner used for retina imaging and analysis. It is based on the next generation Fourier-Domain Optical Coherence technology just emerging from clinical research in the last two years. The ultra-high speed and high resolution features enable the FD-OCT to visualize the retinal tissue with ultra-high clarity in a fraction of seconds.

Glaucoma Analysis Using the Confocal Scanning Laser Ophthalmoscope (cSLO)
The Heidelberg Retina Tomograph (HRT) is a confocal scanning laser ophthalmoscope. A laser light scans the retina in 24 millisecond sequential scans, starting above the retinal surface, then capturing parallel images at increasing depths. The stacks of images can be combined to create a three-dimensional (3-D) topographic image of the retina. Images are aligned and compared using TruTrack™ software for both individual examinations and for detecting progression between examinations.

 
 


TruTrack™ Image Alignment Detects Image Variability and Disease Progression

The Topographic Change Analysis (TCA) software uses TruTrack™ software to look for signs of disease progression. By examining the variability of the three scan sets in an individual examination, sequential examinations can be compared for significant differences by eliminating differences due to image variability such as eye movements and fixation losses. More than simple serial analysis which only subtracts the difference between two examinations, the software identifies statistical differences between examinations, accounting for the within-examination variability. This approach has been validated against a patient series with over ten years of follow-up.

Octopus 300 Threshold Visual Field Analysis

Octopus 300 Pro Perimeter

We have a new staff member: the Octopus 300 Pro Perimeter, which measures field of vision for neurological eye and brain disorders (i.e., glaucoma, brain tumors, and other conditions). This will allow us to be 95% more accurate in determining your field of vision. It also reduces the time it takes for us to test your vision, by ten minutes in some cases.  The Octopus is another way for us to stay at the leading edge of technology and fulfill our commitment to bring you the best eye care possible.

UBM High-frequency A/B-scan

The AVISO modular platform brings QUANTEL MEDICAL technology to the high-end performance level. AVISO combines a high-quality image with unrivalled modularity for ultrasonic imaging of the eye. Ultrasound technology allows our doctors to clearly see parts of the eye that would otherwise be invisible. This has unparalleled value when accessing, glaucoma, flashes and floaters, ocular tumors and retinal detachments.

The PASCAL Dynamic Contour Tonometer (DCT)

This is a digital contact tonometer for ophthalmological applications. The slitlamp mounted device furnishes a numeric output of intra-ocular pressure (IOP) and of ocular pulse amplitude (OPA) upon touching the cornea for a few seconds.

Unlike applanation tonometers which are influenced by corneal thickness and other characteristics of the cornea, and hence may produce misleading estimates of IOP, the PASCAL tonometer provides an accurate and direct measurement of true IOP for more precise glaucoma diagnosis and management.

Dr. Kirstein is the Glaucoma Research Director for Ziemer Ophthalmology, the developer of the Pascal tonometer. Since 2003, he has been closely involved in the development and scientific validation of this exciting new device.

The Topcon SL-D2/D4 Slit Lamp Imaging System

This is a compact, seamless solution for digital documentation of the anterior and posterior segment. It combines the Topcon SL-D2 or D4 Digital Slit Lamp with Topcon's IMAGEnet™ Lite software package.

This system allows the examining doctor to capture, store and share high resolution digital photographs of the front or back of the eye for accurate and efficient documentation of eye disease.
