A.3 Referred to GBZ 76 Appendix D for benchmarks of disturbance of consciousness. A.4 should take measures to reduce intracranial pressure in severe cases in order to improve eye blood circulation and prevent optic nerve damage.

Appendix B

(Normative appendix) Eye examination requirements B.1 routine examination of visual acuity and external eyes, and stick with a glass of 0.5% fluorescein in the conjunctival sac, and then with saline Rinse under the slit lamp microscope to observe the presence of corneal epithelium damage. B.2 should be observed under natural light the size of the pupil of the eyes and the changes in light response. B.3 eye examination with eyesight eyes, pay attention to the optic disc, retinal color changes, with or without edema and blood vessels filling And so on. B.4 Check the presence of a center or sub-center with a flat view. Generally with 2 mm white and red as standard inspection Check, can also be used 1 ~ 3 mm as standard. To the arc field of view, respectively, with 5 mm red, white as the standard visual field inspection. ......
