Visual Evoked Potential (VEP) and Pattern Electroretinography (ERG)
We are proud to be the first office in Alaska to acquire this instrument!
VEP measures the electrical activity in the vision system. When light from an image enters your eye, it is converted into electrical energy at the retina and travels through the optic nerve to the visual cortex of the brain, which processes vision. The Diopsys® VEP test measures the strength of the signal reaching your visual cortex and how fast it gets there.
"ERG provides objective, functional information about the performance of the inner retinal cells of the eye. ERG has been recognized as an effective test in helping to diagnose and manage disease including, age-related macular degeneration, glaucoma, and diabetic edema."

Eye Care Technology
Technological enhancements have improved our doctors' ability to manage and detect eye diseases, aid in fitting difficult contact lenses, and keeping accurate patient records.
optomap Ultra Wide Digital Retinal Imaging
The optomap image is fast, painless and comfortable. It allows a 200 degree view of the retina in one image, versus a normal exam giving the doctor a view of 45 degrees at a time. We aim to take optomap images at your Annual Eye Exam every year, but we also take new pictures whenever we do additional testing, and that can be as often as every 1-3 months.
This panoramic image of your retina allows improved diagnosis and detection of many eye diseases including macular degeneration, retinal detachments and diabetic retinopathy. Early detection means early intervention and more successful treatment.
Is it covered by insurance?
Most insurance companies set a low baseline price for retinal images taken during a routine eye exam. If the images are taken during a special testing appointment or have been deemed medically necessary, however, the price of the images will be billed to your medical insurance and the amount you would be responsible for would depend on your insurance plan and deductible amount.
Optical Coherence Tomography (OCT)
Optical coherence tomography (OCT) is an established medical imaging technique that uses light to capture micrometer-resolution, three-dimensional images from within optical scattering media (e.g., biological tissue).
The OCT scans the back of the eye and assists in the diagnosis and management of retinal eye disease and conditions, such as glaucoma, macular degeneration and retinal lesions. It provides full color, 3-dimensional images. This information is invaluable in determining the treatment process.
Zeiss OCT completes 27,000 A-scans per second. The faster speed provides an extremely high resolution for more accurate diagnosis of hidden eye conditions. This device provides color mapping of the optic nerve, retina and macula. This mapping establishes the presence and severity of a condition, such as glaucoma.
This non-invasive procedure takes about 15 minutes to complete and is covered by most insurance programs and Medicare.
Visual Fields Testing
Peripheral vision testing is important to detect problems associated with the eye, optic nerve and brain. During your Annual Eye Exam, we perform a screening visual fields testing call the Zeiss FDT. This basic visual fields test is to find more obvious issues with your peripheral vision and field of view.
For more advanced visual fields testing, we use the Haag- Streit Octopus 900, the all-in-one perimeter. Your FDT results or other findings during the exam may dictate the need for advanced visual fields with the Octopus 900 to more accurately diagnose problems with peripheral vision.
The Octopus Visual Fields is a non-invasive procedure, takes about 15 minutes to complete, and is covered by most insurance programs and Medicare. Learn more about the visual fields testing at AllAboutVision!
Kowa Digital Retinal Photos
Similar to the optomap, the Kowa Digital Retinal Photo gives a wider field of view of the retina than a traditional eye exam. The Kowa Digital Retinal Photo, however, gives us a more detailed image of specific parts of your eyes, focusing on the macula and optic nerve.
We use the photos to detect things like macular degeneration and damage to the optic nerve from glaucoma. These photos are not typically a part of your normal eye exam unless our doctors determine that a closer look at specific parts of your retina are necessary. They are more likely to be taken during special testing appointments.
Is it covered by insurance?
Retinal images are not typically covered by vision insurance. The Kowa photos are covered by most medical insurance policies, however, depending on your policy and deductible amount much like the optomap.
Digital Slit Lamp Imaging
Digital imaging systems are used to view and capture high quality contrast images of the surface of your eyes. Utilizing the newest Topcon Premier Photo Slit Lamp SL-D 7 our doctors can properly manage and identify problems on the front surface of your eye. Some common conditions include viral infections, corneal foreign bodies, and corneal ulcers, which can be digitally documented in your records using our digital slit lamp.
This imaging and examination is a part of your Annual Eye Exam!
