The United
States Eye Injury Registry (USEIR) developed the Ocular Trauma
Score (OTS) with support from the Centers for Disease Control
and Prevention (CDC)*. The OTS provides a single probability
estimate of an eye trauma patient will obtain a specific visual
range by six months after injury. The OTS can be used as an
aid in the counseling and treatment of eye injury patients,
and is able to direct attention toward resource needs and rehabilitation
during the treatment process. The OTS is meant to be a continually
evolving scoring system to be used by the clinician to facilitate
patient counseling, treatment, rehabilitation, and research. How to calculate the Ocular Trauma Score First, determine the patient’s initial visual acuity after the injury and their tissue diagnoses. Second, assign a raw point value for initial visual acuity from row A from Table 1. Then subtract the appropriate raw points for each diagnosis from rows B-F. (For example, a patient with an initial visual acuity of 1/200, scleral rupture, and retinal detachment would receive a raw OTS score of 80-23-11= 46.) Higher OTS scores tend to indicate a better prognosis. To provide an estimate of the patient’s probability of attaining a specific visual acuity range at a six-month follow-up, locate the row in Table 2 corresponding to the patient’s OTS. (A patient with a raw OTS score of 46 would have an OTS category score of 2.) Table 2 shows the estimated probability of all potential visual outcomes vision after six-months.
Note. Spearman
Correlation of OTS score (1-5) the with actual follow-up visual
acuity category (1-5) for 67% development sample of the original
1275 (n=1,461) cases of the combined data =. 71,p<. 001.
Spearman Correlation of OTS score (1-5) with the actual follow-up
visual acuity category (1-5) for 33% testing sample of original
1275 (n=690) cases of the combined data =. 68 (greater than
original) p<.001. |
