What it is
The retina is the light-sensitive layer at the back of the eye. A dilated retina examination looks for changes such as diabetic retinopathy, retinal holes and tears, and age-related macular changes. For people with diabetes, a retina check is generally advised once a year even when vision seems normal, because early diabetic changes cause no symptoms.
When you might need it
- You have diabetes — an annual retina check is generally advised
- New floaters, flashes of light, or a shadow in your field of vision
- Sudden, distorted or missing central vision
- High spectacle power, or a family history of retinal problems
What happens during your visit
Dilating drops are instilled and the retina is examined in detail once the pupils widen, which takes about 30 minutes. Retinal imaging may be advised where it helps document findings. The findings are explained, and if treatment or a retina specialist's opinion is needed, you are guided to the next step.
Aftercare
Near vision stays blurred and light feels bright for a few hours after dilation. Please arrange not to drive yourself home, and bring sunglasses.
