Some eye conditions develop gradually and may cause few noticeable symptoms in their early stages. Appropriate eye examinations and timely assessment can help identify changes before they significantly affect vision and can support appropriate follow-up or treatment.
Why is early detection important?
Some eye conditions can progress without obvious symptoms, particularly in their early stages. An eye examination can identify changes that a person may not notice in everyday life.
Finding a problem earlier may allow appropriate monitoring, further investigation, treatment or referral depending on the condition.
What can help with early detection?
Regular professional eye examinations are an important part of maintaining eye health. The appropriate frequency depends on factors such as age, symptoms, medical history, risk factors and existing eye conditions.
Additional investigations such as intraocular pressure measurement, visual field testing, OCT or other examinations may be recommended when clinically appropriate.
Do you need an eye examination if your vision seems normal?
Good vision does not necessarily mean that the eyes are free from disease. Some conditions can develop before noticeable changes in vision occur.
People with known risk factors or existing eye conditions may require specific monitoring even when they feel that their vision has not changed.
What changes should prompt an assessment?
New or worsening blurred vision, changes in the visual field, new flashes or floaters, double vision, eye pain or other significant changes should be discussed with an eye-care professional.
Sudden or major changes in vision require prompt assessment.
What happens if a problem is identified?
The next step depends on the finding. An eye-care professional may recommend observation and repeat testing, additional investigations, treatment or referral to another specialist.
Follow-up is particularly important when an existing eye condition or risk factor requires ongoing monitoring.
