In Office Technology

Here at the Optometric Center and Eyewear Galleria  we are on the cutting edge of technology to detect eye disease and visual disorders. Early detection of eye disease can often save your sight and in some cases, may save your life. Dr. Johnson and Dr. Duong may order a specialized test to aid them in a diagnosis of an eye disease or to rule one out. Each instrument is specifically designed to aid ine tdetection of vision abnormalities, so that treatment can begin immediately to minimize complications. Our specialized testing instruments include:

 

OCT

Our new RTVue scanner is used for a variety of purposes. The most common way we use this machine is to evaluate the optic nerve and surrounding area of your retina. We are able to see a 3-D image allowing Dr. Johnson to see swelling of the optic nerve, blood vessel damage and nerve fiber layer atrophy. This instrument allows for early detection of glaucoma so treatment can begin as early as possible to prevent loss of vision. Among other things, we also use the RTVue to take images of nevi (“moles”) on the retina to determine if they are benign or require further evaluation for possible malignancy. In addition to that, we can take a “pachymetry” image of the cornea, allowing us to see corneal thickness. This helps to determine thickness and depth of corneal scars, corneal thickness as it relates to corneal surgery and/or refractive surgery and corneal health.

 

 

 

Auto Refractor

The Auto-refractor is a quick test that allows Dr. Johnson and Dr. Duong to get an objective baseline of a patient’s prescription. This test is done on all patients having a comprehensive exam allowing Dr. Johnson and Dr. Duong to compare the subjective (response driven) prescription to the objective (non-response driven) prescription allowing for the utmost accuracy in spectacle prescriptions.

 

 

Non-Contact Tonometer

Commonly referred to as the “air-puff test,”  this test is essential in detecting changes in your eye health. This too, is part of a comprehensive exam. We are measuring intra-ocular pressure by puffing air at the front of the eye (the cornea) and a reading is taken of how much the cornea has been indented by the air. It is simple, fast and allows Dr. Johnson and Dr. Duong to monitor increases in intra-ocular pressure which can be a sign of glaucoma, ocular hypertension and other eye diseases.

 

 

Visual Fields

- Our visual fields machine is routinely  done with every comprehensive exam. In its “screening mode” it runs approximately 1 ½ to 2 minutes on each eye showing flickering black and white bars to check a patients peripheral or “outer” vision. The patient clicks on a button every time they see the bars flash on the screen. By recording the pattern of bars versus patient clicks, Dr. Johnson and Dr. Duong can check for defects in the vision that may be indicative of glaucoma, retinal tears or any other vision deficiencies.

 

 

Topographer

Our Corneal topographer will map the front of your eye, the cornea. This is done for contact lens wearers, those who have had corneal surgery, including Lasik and other refractive surgeries and those with irregular corneas. This machine quickly takes an image of the cornea and converts it into data for Dr. Johnson and Dr. Duong, such as curvature of the cornea, steepness of the cornea and may show corneal swelling.

 

 

Optomap

The Optomap takes a digital image of the back of the eye (the retina)  and takes less than a second. It is a quick, painless and absolute essential part of the comprehensive eye exam. Optomap takes the place of dilation in most cases and gives Dr. Johnson and Dr. Duong a 200 degree view of the retina which allows them to check for retinal disorders and abnormalities as well as signs of systemic diseases, including but not limited to; hypertension and diabetes. The Optomap was originally designed for a child and is appropriate for patients of all ages. Vision loss and visual symptoms are often a late sign of eye diseases and may be difficult or impossible to improve or reverse at that stage.  Many eye diseases, if detected at an early stage, can be treated successfully without total loss of vision. 

 

 

Foresee

The Foresee is a Macular Degeneration (AMD) test that can help save your sight. The Foresee is a simple, quick and non-invasive was to detect abnormalities in the macula that may suggest the presence of the severe form of AMD. If you have AMD or are an AMD suspect, Dr. Johnson and/or Dr. Duong will monitor your disease with the Foresee and the OCT on a regular basis, as often as every 3 months. Regular monitoring with these instruments, after initial detection, can let Dr. Johnson and Dr. Duong know if your AMD is progressing to severe, wet form of the disease before you experience visual symptoms, at the stage of the disease when treatment is most effective.

 

 

 

Diopsys NOVA-VEP vision Assessment

The Diopsys NOVA-VEP Vision Testing System is a painless, non-invasive test that objectively measures the function of the entire visual pathway from the eyes to the vision center of the brain. The Diopsys NOVA device does this by using a technology called Visual Evoked Potential (VEP). VEP has been demonstrated to aid in the diagnosis and treatment of many disorders including amblyopia, brain injury, stroke, glaucoma, multiple sclerosis, and other vision-related issues. The purpose of this series of tests is to provide comprehensive diagnostic information to better plan your treatment and monitor the results.
