Effects Of Different Operation On Neovascular Glaucoma

Purpose: To evaluate the clinical effects of different surgical management on neovascularglaucoma(NVG).Methods:57eyes in57cases with neovascular glaucoma received different surgical managements wereanalyzed retrospectively．All cases were divided into three groups：20eyes in the group A were treated bycyclocryotherapy,15eyes in the group B were treated by improved trabeculectomy,22eyes in thegroupwere treated with g1aucoma valve combined with retinal photocoagulation. Pre and post-operativeintraocular pressures (I0Ps) were observed and compared between the three groups. The changes in visualacuity were evaluated.Results: On discharge from the hospital, the intraocular pressure (IOP) in group A, B, C were respectively(28.13±4.83)mmHg,(19.24±5.48)mmHg and (21.22±4.76)mmHg, the surgery successful rate wererespectively45％,73.3％and57.1％, which was highest in group B and lowest in group A.Conclusion: Various operation ways may lower the intraocular pressure in neovascular glaucoma atdifferent degrees. Simply the ciliary body cryotherapy can play to relieve pain and reduce the role of IOP,but the effects are less stable and more postoperative complications, such surgery should not be usedvisually eye;"modified trabeculectomy combined with the operation, administration, underwater cauteryapplications can suture, this surgical procedure is simple, easy to operate, and less post-operativecomplications, IOP can be effectively controlled in the iris neovascularization subsided than other obviouseffect of surgery is the treatment of neovascular glaucoma safe, effective, economical surgery; jointall-retinal photocoagulation glaucoma valve implantation, would greatly increase the outflow of aqueoushumor, omentum tissue ischemia and hypoxia situation would be effective in improving the formation ofneovascular growth factor will be greatly reduced, and the formation of the new blood vessels in the irisand angle at will subside significantly, the intraocular pressure at normal levels, significantly reducedpost-operative complications, but the cost is higher...
