Ocular Trauma Score

The Ocular Trauma Score (OTS) was proposed by Kuhn et al in the early 2000s to provide a simple system with few variable to predict final visual outcome of an injured eye. Approximately 2,500 patients were evaluated and over 100 variables were selected from to build the OTS.

The variables used in the OTS are initial vision, rupture, endophthalmitis, perforating injury, retinal detachment (RD) and afferent pupillary defect (APD).

Per the chart to the top right add A+ B+C+D+ E+F to get your raw score. Conversion of raw points into the OTS can predict likelihood of final vision into categories per the chart to the bottom right.

Significance of the OTS

Patient- quality of life, anxiety relief, economic decisions

Ophthalmologist- counseling, triage, management, research
