Imaging & eye health: why people like it
Many people assume an eye exam is mainly about glasses.
But the part most patients find reassuring is seeing and understanding what’s happening with eye health — especially when images can be compared over time.
What is retinal imaging?
Retinal imaging captures a view of the back of the eye, where the retina and optic nerve live.
It can be useful for:
- documenting baseline eye health
- supporting assessment when there are symptoms
- tracking subtle changes over time
What is OCT?
OCT is a scan that can provide cross-sectional views of retinal layers and the optic nerve area.
It’s commonly considered when:
- there are specific findings that need closer assessment
- you have risk factors where tracking detail matters
- your optometrist needs a clearer baseline for future comparison
Do I always need imaging?
No.
The right question is:
- what is recommended for my case today?
- what is optional, and what value does it add?
A good exam makes this clear.
Will you show me the images?
You should expect:
- to see the images (when taken)
- a plain-language explanation of what’s normal vs what’s being watched
- guidance on what changes would matter in future exams
What about meibography?
Meibography is a separate type of imaging used for dry eye assessment — specifically to evaluate the meibomian glands (oil glands) in the eyelids.
It uses infrared light to photograph gland structure and can show atrophy or dropout that is not visible from symptoms alone. It is not part of a routine eye exam but is offered when there is clinical reason to assess meibomian gland health more closely.
See What is meibography and does Spadina Optometry offer it? for a full explanation.
