Ocular Trauma Score (OTS) Medical Algorithm

Description

Kuhn et al developed the ocular trauma score (OTS) to determine the severity of an ocular injury. The authors are from the United States Eye Injury Registry, Helen Keller Foundation, University of Alabama at Birmingham, University of Pecs and Mafraq Hospital in Abu Dhabi.

Parameters:

(1) injuries and complications

(1a) rupture of the globe

(1b) afferent pupillary defect

(1c) endophthalmitis

(1d) retinal detachment

(1e) perforating injury

(2) initial vision

Parameters	Findings	Points
rupture of the globe	absent	0
	present	-23
afferent pupillary defect	absent	0
	present	-10
endophthalmitis	absent	0
	present	-17
retinal detachment	absent	0
	present	-11
perforating injury	absent	0
	present	-14
initial vision	better than 20/40	100
	20/50 to 20/200	90
	19/200 to 1/100	80
	light perception or hand motion	70
	no light perception	60

total score =

= SUM(points for all 6 parameters)

Interpretation:

• minimum score: -15

• maximum score: 100

• The higher the score the better.

Total Score	OTS Category
< 45	1
45 to 65	2
66 to 80	3
81 to 91	4
92 to 100	5

where:

• The 3 highest scores based on the various combinations are 100, 90 and 89.
