This tutorial demonstrates proper alignment and lighting to obtain fundus photographs suitable for AI screening.
Coming soon: our own tutorial video featuring the GlaucoScan 3D-printed adapter.

To use GlaucoScan.ai, you’ll need a clear retinal image (fundus photo) of one eye. You can capture this using a smartphone, a 20D or 28D handheld lens, and our low-cost 3D-printed adapter. The image should clearly show the optic nerve and surrounding retina.
Hold the lens 2–4 cm in front of the patient’s eye, then align your smartphone flashlight through the lens until the retina is visible. Adjust angles and distance to find the clearest view. Dilation is recommended for optimal clarity.
Use our adapter to maintain stable alignment between the light source and the lens for consistent imaging. Switch to video mode (with flash), move slowly, pause when the optic disc is in focus, then grab a screenshot of the clearest frame to upload.
For best results, dim the room and ask the subject to fixate on a still object. Keeping both eyes open often reduces blinking and helps stabilization.
