​​​​​​​Optovue OCT

An Optical Coherence Tomography scan (commonly referred to as an OCT scan) is the latest advancement in imaging technology. Similar to ultrasound, this diagnostic technique employs light rather than sound waves to achieve higher resolution pictures of the structural layers of the back of the eye.

A scanning laser used to analyze the layers of the retina and optic nerve for any signs of eye disease, similar to an CT scan of the eye. It works using light without radiation, and is essential for early diagnosis of glaucoma, macular degeneration and diabetic retinal disease.

With an OCT scan, doctors are provided with color-coded, cross-sectional images of the retina. These detailed images are revolutionizing early detection and treatment of eye conditions such as wet and dry age-related macular degeneration, glaucoma, retinal detachment and diabetic retinopathy.

An OCT scan is a noninvasive, painless test. It is performed in about 10 minutes right in our office. Feel free to contact our office to inquire about an OCT at your next appointment.

Visual Field Testing

A visual field test measures the range of your peripheral or “side” vision to assess whether you have any blind spots (scotomas), peripheral vision loss or visual field abnormalities. It is a straightforward and painless test that does not involve eye drops but does involve the patient’s ability to understand and follow instructions.

An initial visual field screening can be carried out by the optometrist by asking you to keep your gaze fixed on a central object, covering one eye and having you describe what you see at the periphery of your field of view. For a more comprehensive assessment, special equipment might be used to test your visual field. In one such test, you place your chin on a chin rest and look ahead. Lights are flashed on, and you have to press a button whenever you see the light. The lights are bright or dim at different stages of the test. Some of the flashes are purely to check you are concentrating. Each eye is tested separately and the entire test takes 15-45 minutes. These machines can create a computerized map out your visual field to identify if and where you have any deficiencies.

VEP/ERG

Visual Evoked Potentials (VEP) provide objective, quantitative information about the functional integrity of discrete visual pathways in a non-invasive manner. This is new information that is complementary to the structural analysis obtained from technologies such as OCT and Fundus photography, and augments subjective information from standard visual acuity and perimetry.

Electroretinograms (ERG) reflect the integrity of the optics, photoreceptors, bipolar cells and retinal ganglion cells. ERGs may be useful when patients have abnormal VEPs to differentiate between retinal dysfunction occurring in the optic nerve, optic radiations and occipital cortex.

Z-View Aberrometer

Did you know your eyes are like fingerprints? No two are alike—not even your own two eyes. And yet with conventional vision correction, thousands of people may share your same prescription. Based on measurement technology used a generation ago, it’s this ‘one-size-fits-all’ approach that can limit you from seeing beyond the ordinary. For the first time your prescription is a match to your unique optical requirements. Taking what is unique to your eyes and customizing your prescription, no one in the world will have your same iPrint.
