How to use Peek Retina

Peek Retina is a portable smartphone attachment that enables the user to view and capture images of the optic nerve through a dilated pupil.  The Peek Retina camera app (Beta) allows easier capture of retinal images and videos by presenting camera features in an interface which is fully compatible with the Peek Retina hardware. 

Sales of Peek Retina closed permanently in September 2020.  This page is maintained as a service for existing users of Peek Retina devices.  We are no longer able to provide individual support for Peek Retina, except in exceptional circumstances.

Store safely when not in use. Use the Lens Cap to keep dust free. To clean the window gently rub with the dry Microfibre Pouch provided.


  • For professional use.

  • Designed for use on dilated (mydriatic) pupils; use on non-dilated(non-mydriatic) pupils will be very limited and may not offer any imaging inside the eye.

  • For best results hold within 1cm of the eye.

  • Do not use for extended periods on a single eye. Prolonged use may cause patient discomfort and risks eye damage.

  • Multiple short viewings on a single eye are more comfortable for the patient than one long viewing.

  • Total typical examination time is 1-3 minutes, skilled users may be quicker.

  • Normal use may cause the patient’s eye to water, blink or experience a temporary after-image (similar to seeing a camera flash).

  • Do not use if damaged in any way, including a cracked case or lens, broken clamping screw, or if there is any other sign of damage.

  • Follow usual patient cross-contamination guidelines. Avoid potential transfer of diseases between patients by cleaning your Peek Retina before every new patient using an anti-bacterial wipes. 

“When you meet people and you can solve their problem, it’s a great feeling - it is not just my joy, but the joy of the patient. And when you share their joy then that is double joy.”
