What Can An Eye Exam Tell You About Your Health?
As 2025 begins, many people are looking at ways to improve their health for the year ahead. While diet and exercise are often the main things we focus on, eye health is an equally important aspect that is sometimes overlooked.
In fact, eye health may be linked to your overall well-being more than you realise. The eyes can act as a window to the rest of your body and reveal early signs of conditions that might otherwise go unnoticed.
Our experts discuss why annual eye exams are so important and how they can benefit your wider well-being, by helping to detect various health issues early.
Why should you have regular eye exams?
Eye health can change subtly over time, often without obvious symptoms, making regular eye examinations a vital tool to keep your overall wellness in check. By examining the eyes, optometrists can detect early signs of issues that could lead to vision loss or, if left untreated, more serious health concerns.
Catching these problems early is crucial, as timely intervention plays a key role in managing conditions effectively. Routine eye exams also help track changes in vision, ensuring your prescription remains accurate and supports your quality of life.
What can an eye exam detect?
Let’s take a look at some of the top health concerns that eye examinations can catch early:
- High blood pressure (hypertension): Because symptoms are not always obvious, high blood pressure, medically known as hypertension, can sometimes go unnoticed. However, during an eye test, our expert optometrists can spot signs of this condition by examining the blood vessels in the retina, which detects light before it’s turned into visual images by the brain. For example, narrowing or damage to blood vessels in the retina can be a sign of elevated blood pressure in the eye. Since untreated hypertension can lead to serious health issues like heart disease or stroke, early detection is important.
- Diabetes (diabetic retinopathy): Diabetes can significantly impact eye health, particularly through a condition called diabetic retinopathy. This condition develops when high blood sugar levels damage the small blood vessels in the retina. As the blood vessels weaken or leak, it can lead to vision problems and, in severe cases, blindness. An eye exam can detect early signs of diabetic retinopathy, often before any noticeable symptoms appear. Early detection allows for better management of diabetes and helps reduce the risk of serious vision loss.
- Glaucoma: Glaucoma is a group of eye conditions that causes damage to the optic nerve, which is the part of the eye that sends visual information from the retina to the brain. This damage is often caused by increased pressure inside the eye, a condition known as intraocular pressure. Glaucoma typically develops gradually and without noticeable symptoms, so it can go undetected until significant vision loss occurs. Regular eye exams are essential, as they include tests to measure eye pressure and evaluate the optic nerve for signs of damage.
- Age-related macular degeneration: Age-related macular degeneration (AMD) is a condition that affects the macula, which is the central part of the retina responsible for sharp, detailed central vision. AMD is a leading cause of vision loss in older adults, particularly as it progresses with age. The condition causes the cells in the macula to deteriorate, leading to blurry or distorted vision. However, these symptoms often don’t appear until the condition is advanced. An eye exam can identify early signs of AMD, such as changes to the retina, allowing for timely interventions to help preserve vision and manage the condition.
- Brain tumours: Although rare, brain tumours can sometimes be detected through an eye exam. Optometrists may observe increased pressure in the brain, which can cause swelling in the optic nerve – a condition known as papilloedema. Swelling of the optic nerve can indicate problems such as a brain tumour. If papilloedema is found, it can lead to further investigations to confirm the diagnosis and begin appropriate treatment.
Comprehensive vs advanced eye exams
Not all eye exams are the same. We offer advanced eye examinations that go beyond the standard vision tests of standard comprehensive eye exams. These use state of the art technology, such as optical coherence tomography (OCT).
This non-invasive imaging technique captures high-resolution, 3D cross-sectional images of the retina, allowing optometrists to examine its layers in detail. An OCT scan can help detect early signs of conditions like glaucoma, AMD, and diabetic retinopathy, even before symptoms appear. We aim to catch issues early so we can create a tailored plan to manage your eye health effectively.
The importance of advanced eye exams
By detecting early signs of conditions such as high blood pressure, diabetes, or even brain tumours, an eye exam can prompt timely referrals to specialists. This proactive approach ensures that health concerns are addressed promptly. Ultimately, this can lead to better outcomes, peace of mind and a greater sense of control over your well-being.
