Clinician reviewing corneal and retinal scans

Netra Clinical Knowledge Hub

For Health Professionals

Independent, parameter-level interpretation guides, clinical reference articles and comanagement resources for optometrists, ophthalmologists and ophthalmic technicians. Written to be read at the slit lamp, cited to their sources, and free to download.

Diagnostic report interpretation guides

Each guide works through one instrument's report families field by field: what the number measures, how it is sampled, which reference values can reasonably be applied, and where the device stops. Every value is classed as device-defined, clinical reference or no validated cutoff.

The guides in this section are independent educational publications of the Netra Clinical Knowledge Hub, funded by Netra Eye Institute. They are not produced, sponsored, reviewed or endorsed by any instrument manufacturer, do not replace the instrument user manual, and reproduce no manufacturer screens or figures. Product names are used only to identify the instruments discussed. Each guide states its review status on its cover; a draft is not a reviewed resource.
