Corneal Topography

The cornea is the transparent dome-shaped covering on the front of the eye and covers the pupil, iris, and anterior chamber of the eye. Read More

Visual Fields

The visual field refers to the space or range where objects can be seen while the eyes are focused on a central point. Visual field testing, or perimetry. Read More

Ocular Coherence Tomography

Optical coherence tomography (OCT) is an imaging test that provides detailed images of the layers in the optic nerve and retina.  Read More

Fundus Autofluorescence

Fundus autofluorescence (FAF) imaging is an advanced diagnostic technique for observing the fundus. Read More

Electrodiagnostics

Electrodiagnostic testing measures the amount of electrical activity in certain areas of the body. Read More

Macula Risk Testing

The macula is an oval-shaped yellow spot in the eye, located near the center of the retina, which is the layer of tissue light-sensitive located toward the back of the eye. Read More

Electrodiagnostics

Electrodiagnostics is the measurement of electrical activity in the body and can be performed in many areas, including muscles and nerves. In optometry, electrodiagnostic testing is used to observe the functioning of the patient’s retina and optic nerve as it sends electrical signals to the brain. Like many other types of visual diagnostic testing, electrodiagnostic testing is non-invasive and painless.

Electroretinography (ERG) is a common type of electrodiagnostic testing that is similar in function to an electrocardiogram (ECG) for the heart. The patient is subjected to flashes of light, during which the retina’s electrical signals are recorded. This helps the patient’s professional eye care practitioner find abnormalities in the way signals are sent by the retina.

Visual Evoked Response (VER) is another common form of testing that focuses on the pathways that are used to carry electrical signals from the patient’s retina to the brain. During VER testing, the patient is asked to view a moving pattern while activity in the visual pathways is recorded.

Advanced diagnostic and surgical technology plays a crucial role in modern optometry. In many cases, technology is the only means for eye care professionals to diagnose and treat eye disease. More importantly, diagnostic technology is critical for patients who exhibit early stages of devastating eye diseases. Diagnostic testing can be the sole factor that prevents a patient from losing his or her vision from a condition such as age-related macular degeneration (AMD) or glaucoma.

Diagnostic Technology

Optometric technology is paramount upon examination of the retina, cornea, optic nerve, and macula. These areas of the eye contribute significantly to the patient’s vision and can reveal important insight into abnormalities and dysfunction of the eye. Diagnostic technology is helpful for creating treatment plans specific to each patient.

Keratron

The Keratron performs corneal topography. The cornea is the transparent covering over the front of the eye. During corneal topography, the surface of the patient’s cornea is measured on thousands of points. This computer-assisted videokeratography (CAVK) testing device then creates a three-dimensional corneal map, or a color-coded visual, that provides in-depth information about the patient’s corneal structure.

Corneal topography with the Keratron is non-invasive and pain free. In seconds, the eye care professional is provided with information regarding the curvature of the patient’s cornea. This information can be used to determine abnormalities in the cornea. Eye care professionals may also use the results for simulation of contact lens fitting and analyzing a patient’s candidacy for refractive surgery.

Spectralis

Spectralis is an innovative testing system that utilizes optical coherence tomography (OCT) along with other diagnostic technology. OCT provides detailed imaging of the different layers that make up the retina and optic nerve. The Spectralis system also utilizes advanced technology such as spectral-domain optical coherence tomography (SD-OCT). The Spectralis system offers impressively high-resolution images of the eye that are magnified up to one micron, or a thousandth of a millimeter. Spectralis can be used to diagnose conditions such as glaucoma and age-related macular degeneration (AMD).
