Treatment of neovascular glaucoma by ciliary body cryotherapy combined with peripheral retinal cryotherapy

Objective To observe the treatment of ciliary body cryotherapy combined with peripheral retinal cryotherapy for neovascular glaucoma.Methods A retrospective analysis of the drug can not control or failure of other anti-glaucoma surgery received peripheral retinal cryotherapy ciliary body cryotherapy combined surgical treatment of 48 cases of neovascular glaucoma(48 eyes).To observe the change of intraocular pressure,visual acuity,iris neovascularization and complications.Results IOP: the IOP of 28 eyes all controlled uder 21mm Hg,the IOP of 19 eyes which joint antiglaucoma medications controlled under 30mm Hg.Iris neovascularization decreased in 31 eyes(64.58%),neovascularization significantly reduced compared with the preoperative thinning 17 eyes(35.42%).Visual acuity: visual acuity was improved in 14 eyes(29.17%),no change in 21 eyes(56.25%),decreased vision in 13 eyes(27.08%).Postoperative complications: early majority had transient elevation of intraocular pressure.One case of ocular atrophy occurs.Conclusions Ciliary body cryotherapy combined with peripheral retinal cryotherapy can reduce intraocular pressure,so that some patients to retain the original vision,a small number of them has increased.This treatment is a simple operation,easy to master and have safer surgical techniques.
