ETDRS charts for Illuminator cabinet 4M ( 13 feet ), Ophthalmic Clinical Research4 Meter European Wide Series ETDRS Chart 1
To facilitate reliable visual acuity screening for clinical trials and exchange of patient data between doctors, clinics and researchers throughout Europe and beyond, researchers at the University of Crete (Dr. Sotiris Plainis, Prof. Miltiadis Tsilimbaris and Prof. Ioannis Pallikaris), have developed modified ETDRS® charts that contain only capital letters that are common to all three European alphabets (Latin, Greek, Cyrillic), and are thus recognizable for a much wider population.

Hertel Exophthalmometer
This instrument is used for precise exophthalmos measurements (e.g. exophthalmic goiter). The basis of the measurement for exophthalmos determination using the Hertel version is the outer orbital rim (orbital wall) and the apex of the cornea. The integral refraction mirrors with millimeter scales for the left-hand and right-hand measuring halves of the exophthalmometer are calibrated so that the zero mark on the scale will be located in the plane of the resting points of the supports. For exophthalmos measurements the supports are placed against the two temporal orbital walls so that the orbital rim contacts the deepest point of the supports.
Comes with protective metal storage case.

Mars Perceptrix Numbers Contrast Test Set
The Mars Perceptrix numbers Contrast eye chart is unlike many other Contrast tests that merely assess visual acuity using low Contrast targets, the Mars Perceptrix low Contrast test is a true Contrast sensitivity measure that indicates the lowest Contrasts your patients can perceive, rather than the smallest letters they can identify at some low, arbitrarily chosen Contrast. With the Mars test, it is the Contrast, and not the letter size, which diminishes from the beginning to the end of the chart.
