Peripheral retina
We can document lesions, scars, bleeding and pigment changes outside the central retina.
Up to 200 degrees of the retina in one image
Wide-field retinal photography with Optomap
Optomap quickly creates a wide-angle image of the back of the eye. Alongside the macula and optic nerve, large areas of peripheral retina can be recorded and compared at later visits.
Understanding the procedure
More retina in one image – but not every question at once.
Special scanning laser technology captures a very large area of the retina in one image. The test is non-contact, and pupil dilation is often unnecessary for the image itself.
Wide-angle imaging is particularly useful for documenting the retina and monitoring changes over time. It does not automatically replace a careful examination with dilated pupils, especially if you have symptoms or there is concern about damage to the peripheral retina.

Used where needed
What do we use wide-field imaging for?
Its main benefits are a broad overview, documentation and easier comparison over time.
Diabetes
Vascular changes across a large retinal area can be viewed clearly and compared over time.
High short-sightedness
The peripheral retina may have additional changes that need targeted examination.
Monitoring changes over time
Images provide a reproducible record and make it easier to compare findings over longer periods.
Step by step
This is how the wide-angle image is taken.
The brief imaging session is manageable for many patients, including those with sensitive eyes.
Align
Sit in front of the device and position your eye close to the imaging opening.
Look at the target
A fixation point helps centre the image on the required area of the retina.
Capture image
The device scans the retina quickly. Images in other directions of gaze can be taken if needed.
Medical assessment
We enlarge unusual areas, compare them with earlier images and, where needed, examine them with dilated pupils.
Understanding the results
Documentation supports the examination.
A good image shows many areas at once. Edge distortion, eyelids, lashes, small pupils and clouding may hide parts of the retina or create apparent abnormalities.
Flashes, a sudden shower of dark specks, many new spots or a shadow in your visual field need an urgent eye examination, even if a wide-angle image has already been taken.
Well prepared
How to prepare for your visit
- usually no special preparation
- Contact lenses can usually be worn
- report sudden flashes or a shower of dark specks immediately
- Bring previous retinal images for comparison, if available
Frequently asked questions
Clear, concise answers.
Is Optomap the same as normal fundus photography?
Both record the back of the eye. Optomap uses ultra-widefield imaging to capture a much larger area of the retina in one image.
Will my pupils need to be dilated?
Often not for the image itself. An additional examination with dilated pupils may still be necessary, depending on the findings and clinical question.
Can Optomap exclude retinal detachment?
No. Images can provide valuable clues, but relevant symptoms require a full eye examination to rule out a condition reliably.
