AIM:To observe the protective effects of salvianolate on retinal nerve fiber layer thickness after glaucoma filtration surgery.

METHODS:In the research,We studied 65 patients(65 eyes)with acute angle-closure glaucoma who were selected from September 2012 to September 2013 and treated with trabeculectomy. During the 2wk treatment, postoperatively group A were given conventional therapy according to clinical pathway of glaucoma treatment. Besides these treatment, group B were treated with salvianolate 200mg intravenously per day. The changes of the intraocular pressure(IOP)and retinal nerve fiber layer(RNFL)thickness in the two groups were observed and analyzed statistically before surgery, at 1wk and 3mo after surgery.

RESULTS:The IOPs of the two groups at 1wk and 3mo after operation were lower than that before operation but the difference between the two groups was not significant(P>0.05). In group A, the RNFL thickness at 1wk after surgery was less than that before operation at temporal, superior, nasal and inferior(P>0.05). The RNFL thickness at 3mo after surgery was significantly less than those before operation and at 1wk after surgery at temporal, superior, nasal and inferior. In group B, the RNFL thickness at 1wk after surgery were less than that before operation, but the those at nasal and temporal were without statistical significance. The RNFL thickness at 3mo after surgery was less than that before operation(P<0.05)and that at 1wk after surgery(P>0.05). The superior and inferior RNFL thickness of group B were less than those of group A at 1wk after surgery, and the temporal, superior and inferior RNFL thickness in group B were higher than those in group A at 3mo after surgery.

CONCLUSION:Salvianolate can reduce optic RNFL edema and delay its thinning after glaucoma attack.
