The purpose of this paper is to determine the active form of matrix metalloproteinases (MMP-2 and MMP-9) in corneal ulcer and ocular surface disorder patients. A total of 35 patients of corneal ulcer, 20 patients of ocular surface disorders and 10 control subjects were included in this study and estimation of active form of MMP-2 and MMP-9 was done by gelatin zymography. Tear samples were collected by capillary tube method. Both pro-and active forms of MMP-9 were detected in 24 out of 35 patients with corneal ulcer and 15 out of 20 patients with ocular surface disorders. None of the patients were showing MMP-2 activity. Neither MMP-2 nor MMP-9 was detected in the control group. Active forms of MMP-9 are present in tears of severe ulcerative and ocular surface disorder patients. Thus, proteinase inhibitors have been recommended for the treatment of corneal ulcer and ocular surface disorders to reduced the progression of stromal ulcer and to minimize corneal scarring.
