Many ocular diseases develop without any noticeable symptoms.\u00a0 <\/strong><\/h2>\n

Advanced diagnostic equipment allows doctors to detect signs of ocular disease before symptoms are present \u2014preventing significant and permanent vision loss, and enabling early treatment to manage the disease.\u00a0<\/span><\/p>\n

Corneal Mapping (Topography)<\/b><\/h2>\n

Corneal Mapping, also known as Corneal Topography, is a non-invasive diagnostic tool that provides 3-D images of the cornea (the outer layer of the eye responsible for about 70% of <\/span>the eye\u2019s focusing power). <\/span>The images provide details about the cornea\u2019s shape and curvature, and <\/span>enable detection of irregular conditions.\u00a0 <\/span><\/p>\n

Corneal mapping is used to detect certain corneal diseases, abrasions, deformities, and irregular astigmatisms.\u00a0 Corneal mapping is also used to monitor and treat ocular conditions, plan eye surgery, and fit contact lenses.\u00a0<\/span><\/p>\n

The diagnostic test involves sitting in front of a lighted \u201cbowl\u201d and resting your head against a bar.\u00a0 After your data is collected, a color coded image of the corneal shape is generated, using different colors to differentiate elevations (similar to a topographic map of the earth that displays changes in the surface of the land).\u00a0<\/span><\/p>\n

Digital Retinal Imaging<\/b>\u00a0<\/span><\/h2>\n

Digital Retinal Imaging is a non-invasive, diagnostic tool that produces high resolution images of your retina, optic nerve, and other retinal structures at the back of your eye. These retinal images facilitate early detection of ocular diseases, such as glaucoma, diabetic retinopathy and macular degeneration. <\/span><\/p>\n

The images are stored electronically to allow your doctor to detect and measure any changes to your retina at each eye exam.\u00a0\u00a0<\/span><\/p>\n

Optical Coherence Tomography (OCT)<\/b><\/h2>\n

An Optical Coherence Tomography scan (commonly referred to as an OCT scan) is a non-invasive, diagnostic tool that provides color-coded, cross sectional images of the retina, allowing for early detection and treatment of ocular disease.\u00a0 <\/span><\/p>\n

The OCT scan uses a laser (without radiation) to obtain higher resolution images of the <\/span>layers <\/span><\/i>of the retina and optic nerve.\u00a0 <\/span><\/p>\n

It is a critical tool for early diagnosis of macular degeneration, glaucoma, retinal detachment, and diabetic retinal disease.\u00a0<\/span><\/p>\n

If you suspect you have an eye condition, contact an eye doctor<\/a>\u00a0near you, who can diagnose and treat the condition.<\/strong><\/p>\n
