Life-Threatening Conditions: What an Eye Test Can Reveal

Eye health isn’t just about seeing clearly; it is a window into your overall well-being. Regular eye tests are not only essential for maintaining good vision but can also play a critical role in detecting life-threatening conditions. In this blog, we’ll explore some of these conditions that an eye test may uncover and discuss how often you should schedule these tests to protect your health.

The Power of an Eye Exam

When you think of an eye exam, you might associate it with getting your prescription updated or finding the perfect pair of glasses. While this is true, comprehensive eye exams do much more than that. Optometrists are trained to look beyond your visual acuity and assess the overall health of your eyes and your lifestyle.


Detecting High Blood Pressure

High blood pressure is often referred to as the “silent killer” because it can go unnoticed until it causes severe health problems. During an eye test, optometrists can observe the blood vessels in your retina. If they notice abnormalities such as narrowing, bulging, or bleeding, it could be an indication of high blood pressure. Detecting high blood pressure early allows for timely intervention and can potentially save lives.


Uncovering Diabetes

Diabetes is another life-threatening condition that can be first detected during an eye exam. Diabetes affects the small blood vessels in your body, including those in your eyes. Optometrists can identify signs of diabetic retinopathy, a condition that can lead to vision loss if not managed properly. When detected early, diabetics can receive the necessary treatment and lifestyle modifications to prevent the condition from worsening.


Revealing Brain Tumours

Although rare, eye exams can uncover brain tumours. Optic nerve swelling, or papilledema, can be a sign of increased intracranial pressure, which may be due to a tumour or other neurological conditions. In such cases, an optometrist would recommend further tests and consultations with a medical specialist to determine the cause and develop a treatment plan.


Identifying Autoimmune Diseases

Some autoimmune diseases, like multiple sclerosis (MS), can manifest through vision problems. Optic neuritis, which is the inflammation of the optic nerve, is a common early symptom of MS. If you’re experiencing unexplained vision changes, your optometrist may recommend a referral to a neurologist for a more in-depth evaluation.


Recognising High Cholesterol

Just like high blood pressure, high cholesterol levels can have a detrimental impact on your blood vessels, including those in your eyes. Optometrists can observe cholesterol deposits in your eyes, which may indicate a need for cholesterol management and further cardiovascular assessments.


How Often Should You Get Your Eyes Checked?

Given the vital role that eye exams can play in detecting life-threatening conditions, the frequency of these tests is a crucial consideration. Here are some general guidelines to follow:


Children and Teens

For children and teenagers, it’s essential to establish a baseline for their eye health. At six months of age: The first eye exam should occur when your child is around six months old. Between ages three and five, another exam should be scheduled as your child approaches preschool age. After those initial exams, children and teens should undergo annual eye check-ups. These regular exams help ensure that any vision problems or health concerns are addressed early, preventing potential issues from worsening.



For adults, the recommended frequency of eye exams can vary based on your age and risk factors. If you are between the ages of 18 and 60 and have no underlying eye conditions, a comprehensive eye exam every two years is typically sufficient. If you wear contact lenses, have specific eye conditions, are diabetic, or have a family history of eye diseases, annual exams may be necessary. It’s essential to consult with your optometrist to determine the ideal exam schedule for your individual circumstances.



As we age, our risk of developing eye conditions and diseases increases. Therefore, seniors should prioritise their eye health. For individuals aged sixty-five and older, annual eye exams are crucial. Regular eye exams are your first line of defence against both vision problems and the early detection of life-threatening conditions. By following the recommended guidelines for your age group, you can ensure that your eyes are well taken care of.



Your eyes are more than just windows to the world; they are windows into your health. Regular eye exams can be instrumental in identifying life-threatening conditions such as high blood pressure, diabetes, brain tumours, autoimmune diseases, and high cholesterol. By scheduling eye exams at the appropriate intervals, you can take proactive steps to protect your vision and overall well-being. Do not wait until problems arise – prioritise your eye health today.
