Your Spring, TX Optometrist Answers Eye Exam FAQs
Since many eye diseases do not produce symptoms until in an advanced stage, children and adults should have a complete eye exam once a year to detect eye problems as quickly as possible. In addition to diagnosing eye disorders that develop slowly, such as glaucoma, cataracts and macular degeneration, your Spring, TX optometrist may also find that minor vision issues caused by flashers and floaters, dry eye or corneal abnormalities are signs of more serious conditions requiring prompt treatment. In addition, some eye and vision problems are age-related, while others are caused by undiagnosed diabetes, heart disease, high blood pressure or venous insufficiencies.
What Should I Expect During an Eye Exam?
Eye doctors test visual acuity during eye exams using alphabet eye charts. Vision field tests evaluate how well you can see at the periphery of your vision field. If you need corrective lenses, your eye doctor will have you look through a phoropter to determine which lenses give you better vision. Color blindness, depth perception and ocular motility tests (for assessing the ability of your eyes to focus together) are also performed during a complete eye exam. All adults over 40 are given visual field tests to check for the presence of blind spots in the peripheral vision. Blind spots may indicate glaucoma or brain damage caused by silent strokes or tumors. Slit lamp tests may be necessary for detecting corneal ulcers and signs of macular degeneration, diabetic retinopathy or cataracts.
Why are Eyes Dilated During an Eye Exam?
Eye drops formulated to dilate pupils allow optometrists to examine the eye's internal structures using an optometric magnifying lens to view the retina, optic nerve, macula, and capillaries. Your Spring, TX eye doctor will wait about five to 10 minutes after placing drops in your eyes before beginning the examination. Eye dilation is also utilized to obtain accurate measurements for a corrective lens prescription.
What is Slit Lamp Testing?
If you are bothered by blurry or double vision, your Spring, TX optometrist may examine your eyes visually for signs of extraocular muscle impairment or saccadic dysfunction (the ability of your eyes to jump or move quickly from object to another). Slit lamp tests permit detailed inspection of anterior (behind the eye) structures for signs of abnormalities that may indicate eye disease. Using an upright microscope and intense beam of light, an optometrist can examine the cornea, vitreous humor, retina and lens.
