When to see a retina specialist
Warning signs — flashes, floaters, distorted vision — that shouldn't wait.
The retina's role in vision
The retina is the light-sensitive layer at the back of the eye responsible for capturing images and sending them to the brain. Because it plays such a central role in vision, problems affecting the retina can progress quickly and sometimes require urgent attention.
Warning signs that shouldn't wait
- Sudden flashes of light in one or both eyes
- A sudden increase in floaters, or floaters accompanied by flashes
- A dark curtain or shadow appearing in your field of vision
- Sudden blurred or distorted vision, especially straight lines appearing wavy
- Sudden, painless vision loss in one eye
Who should consider routine retina checkups
- People with diabetes, regardless of symptoms
- Those with high myopia (severe short-sightedness)
- Anyone with a family history of retinal disease
- Adults over 50, particularly with concerns about age-related macular changes
What to expect at a retina consultation
A retina evaluation typically includes a dilated eye examination and OCT (optical coherence tomography) imaging, which provides a detailed cross-sectional view of the retina and macula. This helps identify fluid, swelling or structural changes that aren't visible on a standard eye check.
Key takeaway
Sudden flashes, new floaters or a shadow in your vision are signs to seek retina care promptly rather than waiting for your next routine appointment.
