A group of 15 eyes underwent conjunctival advancement only while the other 13 eyes did conjunctival advancement with partial thickness scleral graft. In both study groups, we considered the intraocular pressure(IOP) as our primary outcome and visual acuity(VA) as our secondary outcome. Both were assessed pre-and post-operatively till the last followup possible point. Additionally, we classified the patients according to complete and qualified success criteria.RESULTS: The mean age of the conjunctival advancement group was 36.87±19.25 y, while it was 44.08±18.04 in the other group. In both study groups, the mean IOP significantly increased after revision surgery at 1, 2, 3 mo and the last follow-up visit when compared to prior the surgery(P<0.001). Moreover, VA was significantly improved(P=0.03) in the final follow-up for both surgical techniques. When we compared the change from baseline in both groups, there was no significant difference between IOP improvement in 1 mo(P=0.263), while the difference was significant in 2 mo(P=0.03), 3 mo(P=0.02) and in the final follow-up visit postoperatively. However, this difference was not significant regarding VA(P=0.5).CONCLUSION: The both adaptive techniques of conjunctival advancement and conjunctival advancement with scleral graft are effective for treating patients with lateonset hypotony. Yet, more prospective studies are needed to assert upon these results.展开更多
