HEM300 Hertel Exophthalmometer – Precision Exophthalmos Measurement

The HEM300 Hertel Exophthalmometer is a specialized ophthalmic instrument designed for accurate and reliable exophthalmos measurements, including assessment of exophthalmic goiter (Graves' disease). Whether you're a clinician, ophthalmologist, or medical professional, this tool delivers consistent results you can trust.

How It Works

The Hertel method measures exophthalmos by referencing two key anatomical landmarks:

• The outer orbital rim (orbital wall) – provides a fixed reference point
• The apex of the cornea – the measurement target

The integral refraction mirrors feature millimeter scales for both the left-hand and right-hand measuring halves. These scales are precisely calibrated so that the zero mark aligns with the plane of the resting points of the supports.

Simple, Accurate Measurement Procedure

For exophthalmos measurements, place the supports against the two temporal orbital walls, ensuring the orbital rim contacts the deepest point of the supports. This stable positioning allows for repeatable, precise readings every time.
