How to Refer a Case

Referring a case to any of our disciplines is easy - simply call one of our dedicated Referral Administration Team on 01454 521000 and they will guide you through the process.

Alternatively you can email us: 


If you are looking to make a referral to Rowe for an Ophthalmology case please contact the Reception Team on 01454 521000 option 1 or email We aim to contact the client within 24 hours to book them in for an initial assessment. Emergencies will be dealt with immediately, and emergency appointments can usually be offered on the same day.

If you would prefer to speak to an Ophthalmologist for advice on a case, we offer this service free of charge by calling 01454 521000 option 1. Photos and / or clinical notes can also be emailed to

Photographing the eye advice

Photographing the Eye

Modern digital cameras allow excellent quality macro photography with little practice or financial outlay. The use of flash allows critical evaluation of structures posterior to the pupil as well as the use of retro-illumination to highlight subtle corneal lesions. The high resolution now readily available allows magnified views equivalent to that obtained with high end slit lamps with the added advantage that the patient only has to stay still for the few seconds required to focus and take the image.


We are always happy to view images without any obligation (as are many ophthalmologists). Email us: (it's worth ringing us (01453 844337) to say you will be sending images in case our spam filter is one of its over zealous moods) and definitely if the query is urgent. It also allows sequential record keeping – "is this stromal abscess getting smaller?", "is this catarct getting bigger?". It’s amazing how much more information you can get studying a still image on a screen – sometimes we don't see the wood for the trees.

Which camera?

Digital SLRs:


  • Rapid focussing
  • Minimal delay between shots
  • Burst mode useful for moving patients
  • Good quality lenses improve image quality
  • Availability of dedicated macro lenses
  • Standard macro capability of most included lenses often sufficient


  • Cost, size and fragility
  • Built in flashes further from cameras “visual axis” thus often require more distant position to obtain good tapetal reflex

Compact digital cameras: 


  • Cost, often more robust, pocket sized
  • Ease of use
  • Flash often much closer to optical axis allowing macro photography with tapetal reflection


Slow to focus, slow to ready for next shot – however newer compacts better than ever before.
Some noisy to focus which can reduce compliance when used at closest position
Not all have ability to select spot focus

Camera phones:


  • Always with you
  • Increasingly impressive camera technologies
  • Allows rapid telemedicine referrals
  • Video function often readily available
  • Accessible for owners for use in monitoring where appropriate
  • Flash often very close to lens and therefore allows use as a direct ophthalmoscope where able to have camera LED continuously illuminated allowing distant direct views and close direct fundic views


  • Macro photography may be limited without use of additional lenses
  • LEDs often very bright requiring adjunctive methods to reduce illumination intensity

Shopping list (for all cameras):

  • Macro setting
  • P (programme) setting – allows more control over cameras functions
  • Spot or centre focussing selectable
  • Force flash always on
  • Disable red eye reduction facility
  • Rapid, quiet focussing
  • Shortest delay between photo’s
  • Burst mode useful on digital SLRs (rarely fast enough on compacts to be of use
  • Good quality memory card with rapid write speed
  • Long battery life and / or option to use readily available batteries (eg AA)

Tips for taking ophthalmic photographs:

"Flash, Flower and Focus""Flash"

Force flash always on, turn red eye reduction off.

Macro setting on
Zoom off (select widest angle lens allows)

Allow camera to focus lock before photograph taken, usually half depress button and wait until an audible signal or focussing grid or spot changes colour to confirm focussed.

Practice - ensure comfortable with minimum focus distance by using e.g. text.

Spot or centre focussing selected (without cameras tend to focus on the prominent equine eye lashes)
If autofocus focuses on corneal reflection then focus at lateral canthus, obtain focus lock before moving back to axial view of the eye to obtain focus at level of iris.

Other tips

  • Try and reduce shutter speed to minimum by increasing ISO although note at some very high ISO settings image quality may reduce. This is rarely required if flash on.
  • Clean discharge and remove hairs from cornea.
  • Avoid holding lids open if possible as will obtain corneal reflection of hand and distort lid anatomy.
  • Avoid wearing white or red clothes as these will often cause striking corneal reflections.

Take standard views for all patients:

Whole face – aim to get both tapetal reflections
Whole eye, straight on – aim to fill screen with eye if macro allows, aim to get tapetal reflection – talk to patient just before take picture.
Whole eye, lateral view – aim to skyline corneal curvature and anterior chamber.
Lid anatomy (where relevant)
Eyes open
Eyes closed – induced blink
Lid margins everted if pathology
Third eye lid prolapsed

Fundus photography

Fundus photographs are possible using a compact or DLR with an indirect lens, practice, patience and a dilated pupil. A light source can be secured to the lens of a digital SLR (e.g. pen torch and rubber band) or with a compact a head torch can aid in correct positioning.

Some smart phone cameras lend themselves to fundic photography e.g. iPhone4S
