STATE OF THE ART TESTING AND EQUIPMENT

We utilize the latest advances in computerized technology to provide the most current and comprehensive eye health and vision care.

These include: Corneal Topography, Visual Fields, Visagraph, Visual Evoked Potential, Z-View Aberrometer, Eyescape Examination. Please scroll down for a detailed description of each.

CORNEAL TOPOGRAPHY

Corneal topography is a computerized three-dimensional mapping of the contours of the cornea, the clear dome over the iris and pupil. This advanced mapping shows exactly where your cornea shape changes. It is used to help fit contact lenses in complex cases, monitor corneal swelling that may occur from improper contact lens use, or to monitor corneal diseases such as Keratoconus. Corneal mapping is also used to prepare for and monitoring after laser eye surgery.

VISUAL FIELDS

A visual field analysis involves a computerized mapping of your central and peripheral vision sensitivity to light. This sophisticated, computerized instrument allows us to map the peripheral vision of each eye, which is valuable in assisting in the early detection of many diseases such as Glaucoma, Optic Neuritis, Stroke, or Brain Tumors affecting the visual pathway. These conditions may not affect your eyesight until the condition has become severe. In some cases, a visual field mapping may be the only effective way of detecting these problems, if they exist.

VISAGRAPH

What Does The Visagraph Do?
   The Visagraph gives results in terms of grade level efficiency. This is not a measure of the person’s achievement or capability, but rather a measure of how hard they have to work compared to others in their grade level. Many children may be reading on or above grade level in comprehension and fluency, but using an efficiency level far below their grade level. This means the child is working too hard for the grades they receive.

Who Benefits from the Visagraph?
   The Visagraph is not only for children who exhibit more obvious struggles with reading comprehension, speed, fatigue, headaches. But also for children who are not performing at their appropriate grade level. There is a gap between how intelligent they are and their performance level. Children who work much harder to the same results as their peers.

How Does It Work?
   The Visagraph uses infrared sensors to track eye movements with while the individual reads a passage, and then compares the eye movements with measurements taken from a large study of people. It compares the individual’s performance to the grade level norm established during the study.

   The Visagraph, in tracking the eye movements, measures whether or not the eyes are working as a team to process information. The Visagraph measures many movements that are graphed by grade level. This includes left to right movements, pausing to look at words, length of pauses, moving right to left and down to change lines, and backward movements of the eyes. When combined with a Comprehensive Learning Related Vision Exam, the Visagraph provides insight into whether the poor eye movements are causing the poor reading or whether poor reading is causing the poor eye movements.

How To Proceed
The first step is a comprehensive Learning Related Vision Examination with one of our Developmental Optometrists. This allows our Doctor to evaluate the health and function of the visual system. Utilizing the graphed information, along with the results of the Learning Related Vision Examination, a personalized plan for improving eye movement skills is developed.

VISUAL EVOKED POTENTIAL

A visual evoked potential (VEP) is an evoked potential caused by sensory stimulation of a subject's visual field. Commonly-used visual stimuli are flashing lights, or checkerboards on a video screen that flicker between black on white to white on black (invert contrast).

Visual evoked potentials are very useful in detecting blindness in patients that cannot communicate, such as babies or non-human animals. If repeated stimulation of the visual field causes no changes in EEG potentials, then the subject's brain is probably not receiving any signals from his/her eyes. Other applications include the diagnosis of optic neuritis, which causes the signal to be delayed. Visual evoked potentials are also used in the investigation of basic functions of visual perception.

The term "visual evoked potential" is used interchangeably with "visually evoked potential". It usually refers to responses recorded from the occipital cortex. Sometimes, the term "visual evoked cortical potential" (VECP) is used to distinguish the VEP from retinal or subcortical potentials.

Z-VIEW ABERROMETER

Using the Z-View Aberrometer, it only takes about a minute to take a refraction needed for the new iZon High Resolution Lenses. The customized, comprehensive prescription includes correction measures never before available. By measuring the unique qualities of each of your eyes, an iPrint is produced. The iPrint is a detailed optical map that includes the unique microscopic irregularities of the eye the cause vision distortions or compromises.

The information from your eye examination and iPrint can be combined to produce customized iZon High Resolution Lenses. While other eyeglasses are made for looking, iZon High Resolution Lenses are the first eyeglass lenses made specifically for seeing – seeing with far more sharpness, contrast and clarity than ever before possible.

EYESCAPE EXAMINATION (FUNDUS PHOTOS)

Eyescape is an advanced digital retinal exam. By taking a digital fundus photo image of the back portion of the eye (the retina), the doctors can detect and monitor ocular health on the retinal level. The screening picture that is produced captures a clear view of the optic nerve, blood vessels, macula and fovea.

Fundus photos can be a baseline measurement for future comparison. These photos will be kept as a permanent record and allows the doctor to view in detail the general health of internal portion of eye. A look at the internal view of the eye can be key in detecting high blood pressure, diabetes, and many other systemic and ocular diseases.

With an Eyescape Examination, you can expect:
- An in depth view of the retinal surface (where eye diseases manifest)
- The ability to review images with you
- A permanent record for your medical file, for serial analysis, comparisons and diagnosis
