Blunt ocular can cause persistent change of eye structure and function, the method of detection which is closely related to eye injury including B-can ultrasonography, UBM, OCT, FFA, scanning laser polarimetry, fundus autofluorescence, each examination with particular emphasis. This paper aims to review the advantages and disadvantages of different inspection methods in order to provide reference for clinical diagnosis and treatment of blunt ocular trauma.

AIM: To study the lacrimial pump functions and tear proteins of patients with functional Epiphora.METHODS: One hundred cases(200 eyes)with functional epiphora and 20 cases(40 eyes)of nonfunctional controls were recruited and under routine ophthalmic examinations, including Schirmer I test, Schirmer I test while pressing the lacrimal sac, tear film break-up time(BUT). Enzyme linked immunosorbent assay(ELISA)was used to detect main tear proteins, and the results were compared with control group. RESULTS: Compared the result of the Schirmer I test on the normal subjects while pressing the lacrimal sac with that of releasing the lacrimal sac, the difference was significant(t=-4.008, Pt=-0. 811, P>0.05). The mean BUT was significantly shorter than that in the normal subjects(t=-5.382, PPP>0.05).CONCLUSION: The damage of lacrimal pump function plays a great role in the functional epiphora and the tear proteins of functional epiphora patients changed.
