Having access to technology designed especially to detect asymptomatic eye problems allows optometrists to start treating disorders in their earliest stages. At Lehigh Valley Eye Care Associates, patients from the surrounding areas of Lehigh Valley, Allentown, Whitehall, Bethlehem, and Easton, PA enjoy the benefits of state-of-the-art vision technology as well as the highest quality of care for a comprehensive range of eye diseases, including glaucoma, cataracts, dry eyes, flashers/floaters and diabetes-related eye problems.
An imaging technology providing cross-sectional, high resolution images of your retina, OCT examines retinal and choroidal thickness for signs of disease. Situated between the sclera and retina, the choroid is the pigmented part of your eyeball that supplies oxygen and blood to the retina. A thickened choroid can impair blood flow and promote development of macular degeneration, diabetic retinopathy, glaucoma and other vision-reducing disorders.
During an optical coherence tomography examination, patients sit in front of an OCT machine for about 10 minutes. Scanning occurs without any equipment touching your eyes. In some cases, your Lehigh Valley eye doctors may dilate your eyes to improve results of an OCT.
An optomap ultra-widefield retinal image captures nearly 85 percent of the retina during a scan. Since the image is panoramic, optometrists have a much better view of the retina as well as possible diseases affecting the retina. Traditional methods only reveal 15 percent of the retina. Benefits of this technology include facilitating early detection of vision disorders and high risk diseases such as cardiovascular disease and cancer. Early detection of retinal abnormalities means Allentown eye doctors can administer treatment as soon as possible to mitigate vision and health problems.
Utilizing electrophysiological technology, Diopsys ERG and VEP vision testing provides the most advanced methods for detecting glaucoma, macular degeneration and other serious vision disorders before they begin impairing your ability to see clearly. VEP is the acronym for "Visual Evoked Potential", which analyzes electrical activity throughout your vision system. Specifically, VEP calculates the strength and speed of electrical signals connecting to the visual cortex. Pattern electroretinography (ERG) measures how well your retina functions in response to conversion of light into electrical energy. Healthy retinas immediately transmit electrical impulses to your brain for processing. Retinas suffering impairment delay transmission of electrical impulses.
A corneal topography maps your cornea's surface curvature to determine the quality of cornea and vision health. Lehigh Valley eye doctors use corneal topographies to screen patients before refractive surgery, for examining a patient's eye health following cataract or astigmatism surgery or to assess ocular and corneal surface disorders. CTs may also be indicated for proper fitting of contact lenses or monitoring of corneal vs. ocular wave front aberrations associated with age-related vision diseases.
Visual field technology incorporates devices that monitor your ability to remain fixated on images while maintaining a forward gaze. This type of testing is used to screen for glaucoma, test for signs of macular degeneration and peripheral retinal disease and evaluate functioning of the optic nerve if Allentown eye doctors suspect vision impairment due to tumor, undetected stroke, dietary deficiencies or poor circulation.
