Purpose:
We investigated the possibility of applying cross-linked hyaluronate hydrogel (HA gel) during trabeculectomy in rabbit eyes.
Subjects And Methods:
1. We injected 0.9% salt solution (n = 3), Opegan-HI (n = 3), or HA gel (n = 3) into the subconjunctiva to make a follicle, and investigated its size. 2. After making a limbal-based conjunctival flap and a scleral flap, we injected HA gel or 0.9% salt solution into the subconjunctiva of rabbit eyes and sutured each flap (n = 4 each). Three weeks after the operation, we incised the conjunctiva and investigated the case of peeling away the conjunctival flap or the scleral flap. 3. We performed trabeculectomy with and without subconjunctival HA gel (n = 7 and 6, respectively), and compared the reduction of intraocular pressure between the two groups.
Results:
The results showed that the formation of the follicle was excellent and it was easy to peel away the adhesion. The reduction of intraocular pressure was statistically significant 4 weeks after the operation in which the HA gel was used.
Conclusions:
It could be useful to apply HA gel in trabeculectomy to prevent adhesion.
