Canton Comprehensive Eye Exams
Periodic eye and vision examinations are a fundamental part of preventive health maintenance in our Canton Optometric. Many different eye and vision diseases have no clear indicators or symptoms. Consequently, people are generally not aware that conditions exist. Early identification and treatment of eye and vision issues are essential for retaining good vision and eye health, and when feasible, minimizing the risk of vision loss.
What is a comprehensive eye exam?
An all-encompassing adult eye examination may include, but is not restricted to, the following tests. Unique patient signs and symptoms, coupled with the professional opinion of the eye doctor, can greatly affect the testing completed.
Patient History A patient history really helps to figure out any sort of symptoms the individual is experiencing, at what time they began, the presence of any sort of overall heath issues, prescription medications needed and occupational or environmental conditions that may be impacting vision. Your optometrist at Progressive Family Eye Care will ask about any eye or vision troubles you may be experiencing and about your general health. Your eye doctor will probably also ask about any recent eye or health issues of you and your family.
Visual Acuity Reading charts are regularly used to assess visual acuity. Visual acuity measurements analyze how accurately each eye is seeing. As a component of the testing, you are usually asked to read letters on distance and near reading charts. The final results of visual acuity testing are written as a fraction like 20/40. When assessing distance vision, the top number in the fraction is the standard distance at which assessing is done, twenty feet. The bottom number is the smallest letter size you had the ability to read. A patient with 20/40 visual acuity would need to be within twenty feet of a letter that should be seen at 40 feet to be able to read it properly. Normal distance visual acuity is 20/20.
Preliminary Tests Preliminary testing could include investigation of specified elements of visual function and eye health including depth perception, color vision, eye muscle movements, peripheral or side vision, and the way your pupils respond to light.
Keratometry This kind of examination checks the curvature of the cornea, the clear outer surface of the eye, by focusing a circle of light on the cornea and measuring its reflection. This measurement is essential in identifying the right fit for contact lenses.
Eye Focusing, Eye Teaming, and Eye Movement Testing Evaluation of accommodation, ocular motility and binocular vision determines how efficiently the eyes focus, move and collaborate. In order to secure a clear, single image of what is being observed, the eyes must effectively modify focus, move and work together. This screening will search for issues that prevent your eyes from focusing accurately or make using both eyes simultaneously difficult.
Refraction: Detecting refractive error with a phoropter and retinoscope
Refraction is performed to identify the applicable lens power called for to compensate for any refractive error (nearsightedness, farsightedness, or astigmatism). Employing an instrument knowned as a phoropter, your eye doctor places a sequence of lenses in front of your eyes and measures the way they focus light employing a hand held lighted instrument referred to as a retinoscope. The doctor could decide to employ an automated instrument that automatically analyzes the focusing power of the eye. The power is then honed by the individual's responses to ascertain the lenses that provide for the clearest sight. This testing can be accomplished without utilizing eye drops to ascertain how the eyes behave under common seeing situations. In some cases, for instance for patients who can not respond verbally, or when part of the eyes focusing power could be concealed, eye drops are employed. The drops temporarily keep the eyes from switching focus while testing is performed.
Eye Health and Disease Screening
Tonometry gauges eye pressure. Elevated pressure in the eye signals an increased danger of glaucoma. Usual eye pressures range from 10 to 21 millimeters of mercury (mm Hg), averaging about 14 to 16 mm Hg. Any person with eye pressure greater than 22 mm Hg is at a raised likelihood of developing glaucoma, although many individuals with standard pressure also develop glaucoma.
Exterior evaluation of the eye includes evaluation of the cornea, eyelids, conjunctiva and surrounding eye tissue employing powerful light and magnification.
Evaluation of the lens, retina and posterior section of the eye might be performed by a dilated pupil exam to present a better perspective of the internal structures of the eye.
Supplemental testing At Progressive Family Eye Care serving residents of Canton, supplementary assessments could be called for based upon the final results of the other tests to verify or rule out possible concerns, to clarify uncertain results, or to supply a more comprehensive exam. At the completion of the examination, your optometrist will examine and review the final results of the examination to establish a diagnosis and a treatment plan. Your eye doctor will discuss with you the symptoms and causes of each eye illness found and describe available treatment options. Sometimes, referral for consultation with, or treatment by, another optometrist or a different health care specialist may be advised.
If you have concerns regarding any eye or vision conditions diagnosed, or treatment proposed, don't hesitate to request further information or clarification by contacting your Canton eye doctor.
