Abstract:

Objective    To compare the combined therapy of trabeculectomy with cyclocryotherapy and the single therapy of cyclocryotherapy for neovascular glaucoma. Methods    32 cases of neovascular glaucoma were retrospectively analyzed and randomly divided into two groups:  the cyclocryotherapy group was  treated with cyclocryotherapy, and the combination group with trabeculectomy and cyclocryotherapy. The intraocular pressure (IOP),  anterior chamber reaction and pain intensity were carefully observed after surgery. Results    In the short term after surgery, the average IOP was higher, pain was acuter，and anterior chamber reaction was milder in the cyclocryotherapy group than in the combination group. However, there were no apparent differences in the above three indicators between the two groups during the longterm observation. Conclusion    In the treatment of neovascular glaucoma, the combined therapy of trabeculectomy with cyclocryotherapy can effectively reduce the postoperative IOP and alleviate pain, and thus achieve better therapeutic effect than the single therapy of cyclocryotherapy.
