The modified NOSPECS classification (Table 2) was devised in 1977 as a way of summarizing the severity of GO [49], with an assumed rank order attached to the various clinical features. It is now generally accepted that summary scores are of little value in assessing outcomes [4], and there are 2 further disadvantages to NOSPECS. Firstly, the order of features relates poorly to the order in which an efficient examination is performed: class I eyelid retraction, class II soft-tissue involvement, class III exophthalmos, class IV extraocular muscle involvement, class V corneal involvement, class VI visual loss. Secondly, the features are poorly defined. Without accurate definitions scoring patients remains impossible. Despite this, the mnemonic NOSPECS remains a useful reminder of the features that should be assessed.
