Clinical observation of sodium hyaluronate application in adherent strabotomy / 眼科新进展

ABSTRACT

Objective　To observe the effects and explore the mechanism of orthopia by using viscoelastic substance (sodium hyaluronate)in adherent strabismus(AS).Methods　A total of 29 cases(33 eyes)of AS which were caused by various factors were performed strabotomy,in which sodium hyaluronate was poured into cap tenon space and /or around ocular muscles in which preserved after operation.Ocular movement was requested in 12～24 hours post-operation lest ocular muscles adhered to other tissues again.The main index we observed were the effectiveness of strabotomy and ocular movement.Results　All 33 eyes achieved good results:17 eyes(51.5%) were cured,26 eyes(78.8%) obtained distinct improvement(DI). The operative results have reference to the cause of adherent strabismus,period of muscular adherence and visual function post-operation.No complications were found.Conclusion　 Our observation support that sodium hyaluronate can prevent ocular muscles from re-adhering to other tissues around after strabotomy.Most of the patients can obtain better effects by this viscoelastic therapy.
