The Evaluation Of Surgical Effect For 40 Cases Of Neovascular Glaucoma

Objective: To observe clinical outcome for thetreatment of neovascular glaucoma(NVG) with differentsurgical management. Methods: 40cases(41eyes) of NVGwith different surgical management were analysedretrospectively. All cases were divided into three groups:Group A: Trabuculectomy with MMC was performed in 12cases(13eyes) which had visual acuity and clear refractivemedia with a little neovascularization on the surface of iris.Photocoagulation conducted by fundus fluoresceinangiography was performed in two weeks after operation.Group B:Cryotherapy on peripheral retina and ciliary wasperformed in 13cases(13eyes) which had lost visual functionand had thick neovascularization on the surface of iris. GroupC: Trabeculectomy combining cryotherapy on peripheralretina and ciliary was performed in fifteen cases (fifteen eyes)which had visual acuity and refractive media opacity.Results:The IOP in 9cases were controlled in group A. Therate of success was 69.1%. The IOP in 2 eyes was controlledwith additional drugs which could reduce the IOP. After thefollowing surgery of cryotherapy on ciliary in 2 cases , theirIOP was controlled. The IOP in 9cases were controlled ingroup B. The rate of success was 69.1%. The IOP in 2 eyeswere controlled with additional drugs which could reduce theIOP. After the following surgery of cryotherapy on ciliary in1 cases , their IOP was controlled with additional drugswhich could reduce the IOP. The symptom caused by highIOP was releaved in 1 cases, though his IOP was higher than21 mmHg. The IOP in 12cases were controlled in group C.The rate of success was 80%. The IOP in 2 eyes werecontrolled with additional drugs which could reduce the IOP.After the following surgery of cryotherapy on ciliary in2cases , IOP of 1cases was controlled. The symptom causedby high IOP was releaved in 1 cases, though his IOP washigher than 30mmHg. Group A: The visual acuity wasimproved in 5cases and was preserved in 6cases .One eyehad lost visual function. Group C: The visual acuity wasimproved in 5cases and was preserved in 7 cases .Three eyeshad lost visual function. The neovascularization on thesurface of iris was disappeared in 1~3 weeks.Thepostoperative complications were hyphema, flat anteriorchamber, choroidal detachment and atrophy of eyeball.Conclusion: Vaious surgical management for NVG can bechoosed according to the different condition. Trabuculectomywith MMC was performed in cases which had visual acuityand clear refractive media with a little neovascularizationon the surface of iris.Photocoagulation conducted by fundusfluorescein angiography was performed in two weeks afteroperation. Cryotherapy on peripheral retina and ciliary wasperformed in cases which had lost visual function.Trabeculectomy combining cryotherapy on peripheralretina and ciliary was performed in cases which had visualacuity and refractive media opacity.
