Abstract

Background: During the reinsertion of extraocular muscle to the sclera, the risk of scleral perforation is possible. Endophthalmitis may also result in sequelae of scleral perforation. Reattachment of extraocular muscles using fibrin glue is an alternative option in muscle recession surgeries.
Aim of the study: to evaluate the efficacy of fibrin glue as an adhesive agent and to compare it with muscle suturing.
Materials and methods: In this prospective comparative experimental study, fifty-six eyes of twenty-eight rabbits of the same species (white New Zealand) weighing approximately 2.240 to three kg. All the superior rectus muscles (SRM) were disinserted and recessed 5 mm from the insertion and then reattached to the sclera either by fibrin glue (group 1) or sutures 6/0 vicryl (group 2).
Results: After two weeks, of surgical exploration of SRM in the glued group (28 eyes); 23 eyes (82.14%) the SRM was found in the same location of insertion (5mm recession). While the SRM in the remaining five eyes (17.86%) was slipped with posterior displacement of the muscle. on the other hand, surgical exploration of SRM in the control group was found in the same location of insertion. The correlation between inflammation and slippage was significant.
Conclusion: we concluded that fibrin glue was effective as an alternative to sutures to re-attach rectus muscles during recessions (even in small muscle recession) in strabismus surgery, however postoperative slippage of the muscles and inflammation are considerable complications.
