Effect of Amniotic Membrane Combined with Ciprofloxacin in Curing the Primary Stages of Pseudomonal Keratitis

Background: keratitis caused by pseudomonas aeruginosa is often resulted in severe corneal ulcers and perforation, which leads to losses of vision. human amniotic membrane (ham) forms the inner wall of the membranous sac which surrounds and protects the embryo during gestation. the purpose of this study was to evaluate the effectiveness of the amniotic membrane's healing in rabbits with pseudomonas keratitis. methods: in total 14 rabbits divided in 2 groups of: 1 as control and 2 as experimental amniotic membrane combined with ciprofloxacin. a 0.05 ml suspension of pseudomonas aeruginosa atcc 27853 was injected into rabbit’s corneal stroma, with no interference in control group. in the second group, the amniotic membrane in pieces of 1.5 × 1.5 cm transplanted to the entire corneal surface by eight interrupted 10.0 nylon sutures. in the first day ciprofloxacin drop was injected to the second group every 30 minutes and through second to seventh days every 2 hours. the results of perforation in cornea and the amount of infiltration were registered. results: the results showed that amniotic membrane transplantation (amt) + ciprofloxacin group had 0% perforation and the control group 85.6%. average infiltrations were 5 mm in amt + ciprofloxacin groups and 23.75 mm in control. conclusion: the use of amniotic membrane with ciprofloxacin was effective in prevention of cornea perforation and controlling the process of pseudomonal keratitis remission. the improvement of inflammation rapidly happened in ciprofloxacin + amt group.
