Hyaluronidase in ophthalmic evisceration surgery.

ABSTRACT

BACKGROUND: To research the effectiveness of hyaluronidase in evisceration surgery. METHODS: A total of 34 patients were studied as three groups conventional surgery group (n = 13); isotonic fluid group (n = 8); and hyaluronidase group (n = 13). Hyaluronidase and isotonic fluid were introduced into the uveo-scleral space. Intraocular content was removed, if possible by a one-scoop method, with the aid of a spoon. RESULTS: Removing all the intraocular content as a one-scoop method was achieved in 10 of 13 (77%) in the hyaluronidase group and four of eight (50%) in the isotonic fluid group. The one-scoop method was not possible in any case without the introduction of fluid. The mean durations for the evisceration procedure were 32, 36.6 and 40.5 min in the three groups, respectively (P < 0.05). CONCLUSIONS: Using hyaluronidase in evisceration surgery greatly facilitates and speeds up the removal of all the intraocular content in ophthalmic evisceration surgery.
