    There is interobserver agreement in the assessment of various ocular signs found in coma patients. As measure for observer agreement the parameter kappa (K) was determined for (in-)equality of pupils, reaction of pupils, spontaneous eye movements, and oculocephalic responses. The agreement in the assessment of the pupils to light and in the assessment of (in-)equality of pupils appeared to be satisfactory, but more disagreement occurred in assessing spontaneous eye movements and oculocephalic responses.
