Routine eye exams are essential for early detection to prevent diabetes-related vision loss.
Diabetes Canada recommends that individuals with type 1 diabetes undergo an eye exam within five years of diagnosis and are then rescreened annually. Those with type 2 diabetes should have an exam at diagnosis and be rescreened every 1 to 2 years thereafter.
In addition to retinopathy, optometrists can detect other ocular signs that may indicate undiagnosed diabetes. Fluctuating vision, loss of accommodation, and sudden diplopia are among the non-retinal complications that can raise suspicion of diabetes in otherwise asymptomatic individuals.
Regular preventive eye visits allow optometrists to notice these changes early, facilitating prompt referrals for medical evaluation and diagnosis.
Timely diagnosis of diabetes is essential to minimizing the risk of complications. Delays in identifying diabetes are closely linked to a higher incidence of diabetes-related health issues, including retinopathy.
Late diagnoses of ocular diseases are also linked to poorer quality of life, including physical, psychological, financial, and social aspects.
Early detection through optometric screening enables healthcare providers to devise timely treatment plans, reducing the burden of advanced disease and improving patient outcomes.
