The difference between a basic sight test and a comprehensive examination is largely a difference in what can be measured. A prescription can be determined with a trial frame and a chart. Detecting a retinal tear in the far periphery, or nerve fibre thinning that precedes any visual field loss, cannot.

Just as important as any single instrument is that results are stored and compared. Change over time is the diagnostic signal in most eye disease, and change can only be seen against a record.

A single capture that shows over 80 percent of the retina, often without dilation.

Conventional retinal viewing shows a narrow window at a time and usually needs dilating drops that leave vision blurred for hours. Optomap captures an ultra widefield image in a fraction of a second, displaying over 80 percent of the retina in one panoramic view. That coverage matters because the conditions that hide in the far periphery, retinal tears, holes and early detachment among them, are exactly the ones that cause the most damage when missed.

A three dimensional map built from over 20,000 points across the corneal surface.

Corneal topography projects a pattern of rings onto the front surface of the eye and measures how that pattern distorts, building a three dimensional map from over 20,000 surface points. Every specialty lens fitted here starts from that map. It is also the test that catches keratoconus early, because the cone shaped steepening shows on a topography map long before it shows on an eye chart.

Cross sectional imaging that shows the layers beneath the surface.

OCT uses light waves to build a cross section of the eye at microscopic resolution, the way an ultrasound builds a cross section with sound. Where topography maps the surface, OCT shows what sits underneath it. That makes it the test that distinguishes a stable finding from a progressing one, because thickness can be measured today and compared against the same measurement next year.

Maps the full extent of what each eye sees, including what it has quietly stopped seeing.

Peripheral vision loss is almost never noticed by the person losing it, because the brain fills in the gap. Visual field testing presents targets across the whole field of view and records which are seen and which are missed, producing a map of functional vision that no photograph can give. It is the standard test for glaucoma monitoring and it is also how neurological causes of vision loss are picked up.
