The Optomap is a widefield photo of the back of the eye. In a split second it can take a photo, even through an undilated pupil, capturing up to 80% of the retina. The doctor can use this photo to detect many eye diseases, such as glaucoma, macular degeneration, diabetic retinopathy, retinal detachments, and many other.
The Oculus Keratography is a high resolution scan of the front of the eye. It takes just a few minutes and provides a complete dry eye analysis. It allows the doctor to qualify a variety of factors that contribute to the symptoms of dry eye. These include: meibomian gland function, tear film dynamics, tear break-up time, tear volume and ocular injection. The complete report obtained with each scan allows the doctor and patient to monitor improvement throughout the treatment of process.
The Visual Field (VF), is a test used to determine central or peripheral field loss in patients with optic nerve disease such as glaucoma, retinal diseases, and neurological diseases such as stroke.
Whereas the Optos is a wide field screening photo of the back of the eye, fundus photography is a more detailed image of the optic nerve, macula, and vasculature. Because this is a specialized camera attached to a microscope, the quality of the image is superior to that of the Optomap.
Maculogix: Adapt Dx
AdaptDx is a dark adaptometer, meaning that it measures the recovery of vision when going from daylight to darkness. It has been shown that this is the earliest detectable symptom of macular degeneration, allowing macular degeneration to be detected years prior to the doctor seeing it on an eye exam. This test takes only a few minutes to run and is 90% specific for diagnosing macular degeration!
The Optical Coherence Tomography (OCT), is a high resolution and cross sectional image of both the anterior and posterior parts of the eye. It is similar to an X-ray or CT scan in other parts of the body. This 3D view of the retina and optic nerve allows the doctor to more easily and quickly detect and treat diseases such as glaucoma, macular degeneration, retinal swelling.
The Electroretinography (ERG), is a test that measures the electrical response of retinal cells. The doctor can analyze the pattern obtained to diagnose retinal disease at an earlier point in the disease process; sooner than with most other diagnostic testing. It can be used to detect and treat various types of retinal disease, most notably macular degeneration and diabetic retinopathy, as well as optic nerve diseases such as glaucoma.
Visual Evoked Potential
The Visual Evoked Potential (VEP), is a test that measures the electrical response of the brain in response to a visual response. The doctor can analyze the response and determine whether the pathways from your eye to your brain are normal, or if there is a disease process causing that pathway to be disrupted.
