It has first been suggested in 1969 by S.C. Werner and delivers the following classification:
- Class 0: No signs or symptoms
- Class 1: Only signs, no symptoms (e. g. lid retraction)
- Class 2: Soft tissue involvement
- Class 3: Proptosis
- Class 4: Extraocular muscle involvement
- Class 5: Corneal involvement
- Class 6: Sight loss.
Within classes 1 to 6 the investigator has to differentiate the severeity grades 0, A, B, C.
The NOSPECS-Scheme is widely used but suffers from numerous ambiguities. A more modern and unambiguous graduation is LEMO Classification.
