Your glasses still work well. You can read comfortably. So why might your eye doctor suggest another test?
This October, take a broader view of eye health. A stable prescription tells us something useful about your vision, but it cannot answer every question about your eyes. At Inclima Eye Care in West Haven, comprehensive eye exams bring together your history, vision measurements and eye health findings to help us recommend care that fits you.
How Different Types of Eye Tests Work
During an exam, each assessment has a specific purpose:
- Clarity: An eye chart checks how clearly you see at tested distances. Refraction, the “better one or two?” portion, helps determine the lens prescription that brings objects into focus.
- Eye pressure: Tonometry measures pressure inside the eye. Your doctor interprets the result alongside the optic nerve examination and other findings. A reading within the usual range does not, by itself, rule out glaucoma.
- Retinal health: Examining the light-sensitive tissue at the back of the eye provides information about its condition. Dilation may help your doctor see the retina and optic nerve more fully.
These findings complement each other. No single measurement rules out every eye condition.
Why Your Exam May Include Additional Tests
Your exam starts with a conversation. Share medications, medical conditions, family eye history and changes in comfort or daily activities, even if your prescription seems unchanged.
Your doctor may recommend OCT imaging for a closer view of retinal layers, visual field testing to assess areas of your vision, or corneal topography to map the curvature of the cornea, the eye’s clear front surface. The choice depends on a question raised by your history or exam.
For example, persistent contact lens discomfort may call for assessment of the tear film or corneal shape. That information can help guide dry eye care or a scleral lens evaluation when appropriate.
Two people with the same prescription may therefore need different assessments. What matters is the reason for each test and how the information will help guide your care.
Where Specialized Retinal Testing May Fit
In selected cases, your doctor may recommend electroretinography (ERG) testing. ERG records the retina’s electrical response to light, providing information about retinal function.
It is a specialized assessment chosen for a particular clinical question. It is not a routine requirement for everyone, and it cannot detect or rule out every eye disease. Your doctor interprets it alongside your history and other results.
What Do Your Results and Follow-Up Mean?
A recommendation for another test is not a diagnosis. Your doctor may want to clarify an unexpected finding, establish a starting point for future comparisons or monitor a known condition.
Ask:
- What will this test help clarify?
- How could the result change my care?
- What does follow-up involve, and when should I return?
You can also ask whether extra testing will happen today or at a separate visit, and whether you need to prepare.
Follow-up may mean a repeat measurement, treatment review or eye disease co-management. Your clinician recommends the timing of your next exam based on your history, risk factors and findings.
