In general sciences like physics and chemistry it is relatively easy to quantify a value. However in medical science it is not always easy and at times we have to make a compromise. An effort has been made to quantify ocular trauma (eye injuries) based on loss of structure and loss of function. The loss of structure is graded in percentage from a formula and the loss of function is also graded in percentage mainly from loss of vision. Structural loss and functional loss gives total loss. Both are plotted on a graph paper. Recording is done at weekly interval for moderate injuries. For severe injuries it can be done at monthly interval. A horizontal line of 20 cm is drawn at the bottom of graph paper. From the centre of this line a vertical line of 10 cm is drawn. Structural damage is noted on the left side of vertical line and the functional damage on the right side at weekly interval for 8 to 10 weeks. At the end of 10 weeks usually a somewhat triangular area is formed which is labeled as ocular traumagram. Each 1 sq.cm.box enclosed in traumagram indicates one Trauma Unit (T.U.) Thus a quantitative value of ocular trauma is obtained. Further details of construction are given in the section of methods. Different types ocular traumagrams are expected in different types of injury.
