Eye ExamHouston, TX
Similar to one’s physical or oral health, seeking regular eye exams is crucial to the health of one’s vision. The longer a patient avoids an eye exam, the more likely certain issues can develop and remain untreated. As a person’s vision changes with age, there is a fairly strong chance they will need some form of prescription lens or contact to help. An eye exam is a medical appointment that will allow us to measure the health, functionality and overall level of one’s vision.
Eye exams are offered at Vision Corner Uptown in Houston and the surrounding area. Since certain health conditions can negatively impact one’s vision, we will also check for specific signs of vision issues during the appointment. While the number of times a patient needs an eye exam each year can vary, we have the ability to provide an eye exam in as little as 30 minutes.
Why eye exams are important
Eye examinations make it possible to detect problems with the eyes as early as possible. It also gives an eye doctor a chance to analyze the person's vision, correct vision problems and educate patients on how to take proper care of their eyes.
There are a number of factors that determine how frequently each person needs oral examinations, like the patient's family history, age and overall health. The guidelines for how often a person needs an eye exam include:
1. Patients who are three years old and younger
An optometrist might look for signs of common eye issues, like crossed eyes and lazy eyes, when examining patients in this age bracket. Parents should bring their child in for their first comprehensive eye exams before they reach the age of five.
2. Children and teenagers
A child's vision should be evaluated before they start grade school. If the child does not show signs of any vision problems after the first test and there is no history of vision-related problems in the family, the child should only need to come in for an appointment every one to two years.
People who are healthy without any signs of vision problems should get an eye examination once every:
Others will have to get eye exams more often, like:
Those who fall into this category should follow the recommendations of an optometrist.
Benefits of an eye exam
With a regular eye exam, we can help patients receive the treatment they need to maintain healthy vision.
While it can be easy for people to assume they do not need an eye exam if there are no serious issues with their vision, an eye exam at least once every two years is important. As an optometrist, we can identify the early warning signs of any developing eye health issues. Even though the symptoms may not be immediately noticeable or impacting to the patient’s vision, they will only get worse over time.
Benefits of an eye exam at our practice include:
We will also go over various causing factors of eye issues, including genetic and environmental factors. Our goal is to help the patient continue to maintain healthy vision that does not hinder functionality by measuring how well they see. With various tests and methods, we can help determine the level of vision the patient has, even down to each individual eye. This will help us to customize the treatment.
What to expect
Eye exams consist of a number of tests that are administered to evaluate a patient's vision and to diagnose eye diseases. These tests are usually conducted by optometrists and involve the use of various instruments and charts. Each test administered during an eye examination is done to evaluate a specific aspect of the patient's vision or eyes.
Patients are advised to come in for their appointments so they feel relaxed and not rushed. Eye exams typically include:
While the eye exam can take as little as 30 minutes, there are factors that can lengthen the treatment. Regardless, our team will take every step to provide a comfortable and efficient process. If the patient needs new eyewear or needs to update a current prescription, we can help them review the possible options.
During an eye exam, we will:
These tests are fairly easy to complete and may not typically take much time during an eye exam.
Review the patient’s medical history
By reviewing the patient’s medical history, we can help take any pre-existing health factors into account. If the patient’s family has a history of a specific eye issue or condition that impacts the vision, then we can check for signs of that too. Gathering information on the patient’s current condition and medical history will allow us to customize the treatment.
Eye muscle movement and cover tests
With an eye muscle movement test, we can check the alignment of the eyes by watching them follow a pen or target as it moves in different directions. A cover test measures how well the eyes work together. The cover test involves covering one of the patient’s eyes and having them attempt to see how the eyes move. We mainly use the cover test to look for any signs of strabismus.
Examine the pupils and their reaction to light
By examining the pupils, we will measure how well they adjust to light and close objects. We can also use this to measure the whites of a patient’s eyes and the position of the eyelids.
Measure the eye’s ability to read from a distance (Visual acuity test)
During this test, the patient will view a chart with rows of letters on it. Each row gets smaller and smaller as the patient reads down the list. The patient will read the letters while covering one eye each time until they are unable to read more.
If necessary, we may dilate the patient’s pupils to help us see the back of the eye. By using a tool known as an ophthalmoscope, we can view the retina, blood vessels, vitreous fluid in the eye and the head of the optic nerve. We can check for various conditions and signs of damage as well.
The various types of eye exams
There are many other tests that might be performed during an eye exam, depending on the findings of the initial evaluation or any problems the patient is dealing with. These include:
Eye muscle test: This is done to analyze the muscles in charge of eye movement. The eye doctor examines the patient's eye as they look at a moving object.
Visual acuity test: This is used to evaluate how clearly a person can see. The optometrist asks the patient to call out letters on a Snellen chart or a screen. The eyes are tested individually, and the test is used to evaluate near and far vision.
Refraction assessment: This is used to determine the type of lens prescription that will best address the patient's vision issues. It can be done with a computerized refractor or a retinoscopy. The procedure involves having the patient look through a machine that contains different lenses while calling out letters from a chart.
Visual field (perimetry) test: This is used to determine if the patient has issues seeing out of the sides of their eyes. It can include:
Color vision testing: This test is done to evaluate how well the patient's eyes pick up colors.
Retinal examination: This is used to analyze the back of a patient's eyes and the important areas like the blood vessels that feed the retina, the optic disc and the retina. The patient's pupils are dilated to prevent them from shrinking as the optometrist shines a light inside the eyes to examine them.
Direct examination: The eye doctor shines a light into the patient's eye to examine them.
Indirect exam: The optometrist uses a bright light and a condensing lens to view the structures of the eye in great detail.
