Diabetic Eye Disease
Leakage of blood vessels in the back of the eye is an early sign of diabetes. Background diabetic retinopathy is an early sign of damage to the retina at the back of the eye, where blood vessels begin to weaken and leak. The leakage causes accumulations of yellowish proteins and fatty substances. Here are symptoms of diabetic eye disease:
- Fluctuating vision
- Eye floaters and spots
- Development of a scotoma or shadow in your field of view
- Blurry and/or distorted vision
- Corneal abnormalities such as slow healing of wounds due to corneal abrasions
- Double vision
- Eye pain
During an eye examination, your eye doctor will look for other signs of diabetic retinopathy and diabetic eye disease. Signs of eye damage found in the retina can include swelling, deposits and evidence of bleeding or leakage of fluids from blood vessels.
Comprehensive Eye and Vision Examination
A comprehensive adult eye and vision examination may include, but is not limited to, the following tests. Individual patient signs and symptoms, along with the professional judgment of the doctor, may significantly influence the testing done.
- Patient History--Detailed questions to determine symptoms, medications, general health and family history.
- Visual Acuity--Measurements to see how clearly each eye is seeing.
- Preliminary Tests--Testing may include visual function and eye health tests such as peripheral or side vision, depth perception, eye muscle movements and pupil responses to light.
- Refraction--Measurements of the appropriate lens power to compensate for any refractive error. (Nearsightedness, farsightedness & astigmatism)
- Eye Focusing, Eye Teaming, and Eye Movement Testing--Assessment of accommodation, ocular motility and binocular vision to determine how well the eyes work together.
- Eye Health Evaluation--Tonometry measures eye pressure for glaucoma. The external eye is evaluated with a microscope. The internal eye evaluation may include a dilated pupil for a better view.
What is glaucoma?
- Glaucoma is an eye disease in which the internal fluid pressure of your eye rises to a point that the optic nerve is damaged. The pressure that builds up is usually due to inadequate drainage of fluid normally produced in your eyes. Glaucoma is one of the leading causes of blindness in the U.S..
- Glaucoma most frequently occurs in individuals over the age of 40, and there is a hereditary tendency for the development of the disease in some families.It is estimated that over 2 million Americans have glaucoma and this number is expected to rise as more of our population grows older.
- If diagnosed at an early stage, glaucoma can often be controlled and little or no further vision loss may occur. If left untreated, first peripheral vision and then central vision will be affected and blindness may result.
- A comprehensive optometric examination will include tests for glaucoma. A simple, painless procedure called tonometry measures the internal pressure of your eye. Your optometrist will also look into your eye to observe the health of the optic nerve and measure your field of vision.
- Glaucoma is usually effectively treated with prescription eye drops and medicines that must be taken regularly. In some cases, laser therapy or surgery may be required. The goal of the treatment is to prevent loss of vision by lowering the fluid pressure in the eye.
A cataract is a clouding of the eye's natural lens, which lies behind the iris and the pupil. Cataracts are the most common cause of vision loss in people over age 40 and are the principal cause of blindness in the world. Today, cataracts affect more than 22 million Americans age 40 and older.
A cataract starts out small and at first has little effect on your vision. You may notice that your vision is blurred a little, like looking through a cloudy piece of glass or viewing an impressionist painting. A cataract may make light from the sun or a lamp seem too bright or glaring. Or you may notice when you drive at night that the oncoming headlights cause more glare than before. Colors may not appear as bright as they once did.
If you think you have a cataract, see us for a comprehensive exam to find out for sure.
Benefits of 3-D Vision
The ability to perceive depth in a 3D presentation turns out to be a highly sensitive test of a range of vision health indicators and much more sensitive than the standard eye chart that has been in use for 150 years. This is because 3D viewing requires that both eyes function in a coordinated manner, as they converge, focus and track the 3D image. The good news is that for the 1 in 4 children that may have underlying issues with vision, 3D viewing can help identify and even treat these undetected problems. Symptoms indicating a potential problem viewing images in 3D can vary, but some common symptoms include headaches, blurred vision, nausea and dizziness.
These conditions generally respond well to treatments afforded by a comprehensive eye exam. As an added benefit the treatments will additionally assist the child in most all reading and learning tasks.
Vision and Learning
Reading requires the integration of a number of different vision skills: visual acuity, visual fixation, accommodation, binocular fusion, convergence, field of vision, and form perception. Of these, only one is checked by the typical school eye chart test. A comprehensive optometric examination, however, does cover these vision skills. It is a must for every child who is having trouble reading.
- Visual Acuity: Visual acuity is the ability to see objects clearly. It is usually the only skill assessed in a school vision screening. The typical school eye chart is designed to be seen at 20 feet and measures how well or poorly the child sees at that distance.
- Visual Fixation: Fixation is the skill utilized to aim the eyes accurately. Pursuit fixation is the ability to follow a moving object with the eyes.
- Accommodation: Accommodation is the ability to adjust the focus of the eyes. Children frequently use this vision skill in the classroom as they shift their attention between their book and the chalkboard.
- Binocular Fusion; Binocular fusion refers to the brain's ability to gather information received from each eye separately and form a single, unified image
- Convergence: Convergence is the ability to turn the two eyes toward each other to look at a close object. School desk work is one instance in which a child depends on this vision skill.
- Field of Vision: Field of vision is the wide area over which vision is possible
- Perception: Visual perception is the total process responsible for the reception and understanding of what is seen. Good visual perception is necessary for successful school achievement.
- Regular optometric care can help assure that a child will have the visual skills necessary for successful classroom performance.
