Visual Function Assessment for Clinical Research

A complete toolbox for psychophysical assessment of visual function

Fast, accurate, and more sensitive than standard tests

For normal, defective, paediatric, ageing and low vision populations

How to Choose a Test

Metropsis is ideal for clinical, pre-clinical and drug trials:

age-related macular degeneration
multiple sclerosis
astigmatic error
side effects of prescription drugs
dry eye

retinal pigment epithelial atrophy
cardiovascular disease
neurodegenerative disease
genetic role in photo-transduction cascade
typical acquired colour vision deficiencies
normal ageing
exposure to chemicals
ocular hypertension

optic neuritis
face recognition
light and dark adaptation
neural age-related loss


Easy screening of Best Corrected Visual Acuity using the familiar chart.


Single Optotype

A finer scale of letter sizes allows detection of more subtle changes in visual acuity.

Single Optotype Acuity Test

Landolt C

Especially suitable for pre-readers, illiterates and subjects unfamiliar with the Latin alphabet.

Landolt C Acuity Test

Gabor Patch

For a more detailed characterisation of spatial visual abilities.

Gabor Patch Contrast Test


Quick, easy and efficient to score, measures contrast acuity using customised spatial frequencies.

Pelli-Robson Contrast Test

Flicker Test

Temporal contrast sensitivity “Flicker Test” is informative of light and dark adaptation abilities.

Temporal Contrast Flicker Test

Depth Discrimination

Depth discrimination is an informative measure of binocular vision.

RDS Depth Discrimination

Cambridge Colour

Rapid screening, or full assessment of changes in colour discrimination.

Cambridge Colour Test

Low Vision Colour

Uses a larger stimulus size which is more suitable for patients with low vision.

Low Vision Colour Test

Universal Colour Test

A discrimination task which is simple enough even for children as young as 5 years old.
