Non-Contact Tonometer - This instrument measures your intra-ocular pressure(IOP), your eye pressure. Just like your blood has pressure, so do your eyes. Some know it as the "glaucoma test". It is actually part of a battery of tests that we use to diagnose glaucoma [Starting with family history, IOP, optic nerve appearance, nerve fiber layer density (GDx), visual fields, presence of high myopia]. Fixation Target: Red Dot
Auto-Refractor/Auto-Keratometer (Auto's) - This instrument determines your prescription; that is, how nearsighted, farsighted or how much astigmatism you have. It is accurate enough to prescribe from. It also measures your central corneal curvatures, which is essential to have for fitting contact lenses and in diagnosing and following corneal eye diseases. Fixation Target: Airplane
Corneal Topographer (Topo's) - This instrument measures 8,000 curvature points across the entire corneal surface. It is used in fitting contact lenses, in diagnosing and following corneal eye diseases (especially keratoconus), and in pre- and post-op eye surgeries (especially Lasik). And because an even tear layer is essential for this instrument to get good reading, it can assess tear quality and diagnose dry eye. Fixation Target: Red dot down the middle of all the circles.
Auto-perimeter (Visual Fields) - This instrument maps your peripheral vision. In the screening mode, it detects generalized losses in peripheral vision. In the full threshold mode, it specifically determines where peripheral field defects are located and how deep they are. It is used to diagnose and follow many eye, optic nerve and brain diseases (diabetic retinopathy or macular degeneration, glaucoma or multiple scleroses, pituitary gland tumor or stroke). Fixation Target: Black dot
GDx: This instrument measures the exact density of the nerve fiber layer at the optic nerve head. An average optic nerve consists of 1 1/2 million individual optic nerve fibers, and losses of nerve fiber layer can occur up to five years prior to detectable losses in vision or changes in optic nerve appearance. It can detect glaucoma and other optic verve diseases (multiple sclerosis) very early, when treatment is more effective. Fixation Target: Blinking red dot looks like an "Equal Sign"
OptoMap Retinal Photography - The OptoMap digital retinal imaging instrument captures a highly detailed view of your optic nerve, the blood vessels in your eye, and your macula (the most sensitive part of the retina). Having photographic documentation of your retinas allows for better and earlier diagnosis of most major eye diseases (including macular degeneration, glaucoma, and retinal bleeding from diabetes or high blood pressure). The photos only require a few minutes to take/develop, and do not require dilated pupils. Fixation Target: Green circle with red rim.
