At Edison eye Care we take pride in utilizing state-of-the-art technology to offer a more comprehensive eye exam in a comfortable, welcoming environment. Our automated refraction systems allow us to quickly determine your glasses prescription while demonstrating in real time how we can improve your vision. Such instruments as our fundus camera, optical coherence tomograper, corneal topographer, and automated perimeter allow us to identify eye disease earlier than ever before. Early detection is key to better outcomes for disease prevention.
Our fundus camera images the inner portion of the eye called the retina, which is the area of light-sensitive cells at the back of your eye that is responsible for receiving light and transmitting it into messages that are sent up to the brain. This is often used to document the findings of a dilated fundus evaluation. By capturing these images yearly, our doctors are able to detect subtle changes that often go unoticed by following written documetentation alone. As they say, a picture is worth a thousand words!
Optical Coherence Tomography uses light waves to take cross-section images of your retina. The technology behind OCT enables your eye doctor to see each of the different layers that make up the retina. By being able to see these and measure them, they can obtain a much clearer picture of the overall health and condition of your eyes.
When you choose to have an OCT scan at fairly regular intervals, such as during your normal comprehensive eye exams, your eye doctor can compare newer results to previous ones. This helps them to build up a picture of the health of your eyes, and spot any changes which may be concerning, early, before they cause symptoms or have a permanent effect on your vision.
Corneal topography maps the frontmost part of the eye called the cornea. The cornea is a high power lens that in tandem with the inner crystalline lens focuses light on the retina. Corneal topography is able to detect small distortions of the cornea earlier than previous techniques. Any irregularity in the cornea will disort its optics causing blurry vision. The most common form of cornea irregularity is called astigmatism, which is improved with glasses and contact lenses. Less common distortions of the cornea include keratoconus, which often requires specialty contact lenses to provide clear vision.
Automated perimetry, often called visual field testing, detects any subtle loss of vision in specific areas of what is known as your visual field. Alongside our other diagnostic tests, this device may reveal glaucoma damage, visual distortion from macular degeneration, damage from high risk medications such as Plaquenil (hydroxychloroquine), and vision loss from a stroke or traumatic brain injury. It is an essential part of the medical eye care that we provide and provides a window into the neurology of the brain.
