[A comparative study of thio-tepa and mitomycin C in the treatment of pterygium. Preliminary results].

概要
OBJECTIVE
To compare the efficacy of Thio-tepa and Mitomycine C to obviate recurrence; to compare cost-efficacy ratios; to evaluate their facility of use and their complications.
METHODS
In a prospective blinded study, 36 patients undergoing surgery for 46 primary and recurrent pterygium were assigned randomly to three groups: group 1 received 0.02 mg/ml of Mitomycine C three times daily for 5 days; group 2 received Thio-tepa four times daily for 6 weeks, group 3 served as a control receiving distilled water three times daily for five days.
RESULTS
Recurrence rates were 38%, in group 1; 28% in group 2; 82% in group 3 respectively. Follow-up ranged from 15 to 44 weeks (mean 27.93 +/- 8.9 weeks). Mean delay recurrence time was 6.3 weeks. Topical Mitomycin caused: iritis, conjunctival irritation, excessive lacrymation, photophobia, ocular pain; Thio-tepa caused: photophobia, foreign body sensation, headache.
CONCLUSIONS
Mitomycine C appears to be an effective and safe adjunctive treatment for this cost-efficacy and this facility of use comparison.
