Abstract:
Background Neovascular glaucoma is a type of refractory glaucoma.Biological amnion combined with glaucoma valve implantation is a primary therapy and its long-term effectiveness is noticeable. Objective The goal of this Survey was to evaluate the effectiveness of biological amnion combined with glaucoma valve implantation for neovascular glaucoma and compare the clinical outcome with simple glaucoma valve implantation. Methods This was a retrospective observational case series.The clinical data of 44 eyes of 44 patients received biological amnion combined with glaucoma valve implantation for neovascular glaucoma and 43 eyes of 43 patients received simple glaucoma valve implantation for neovascular glaucoma were retrospectively analyzed and compared.The age,sex and disease-cause were matched between these two groups.Patients were followed-up for 24 months after operation.Surgery success was identified as the intraocular pressure(IOP)<21 mmHg after operation.Written informed consent was obtained from each patient prior to the operation.Results The IOP was<21 mmHg throughout the follow-up duration in both groups.No significant difierence was found in the IOP value in 1 week after operation between two groups(t=-5.34,P=0.60).However,IOP values were lower in biological amnion combined with glaucoma valve implantation group in 3,12 and 24 months after operation than those of simple glaucoma valve implantation(t=6.64,t=5.00,t=7.81,P<0.01).Operation successful rates in biological amnion combined with glaucoma valve implantation group were 97.73％.93.18％。90.24％and 82.05％in 1 week,3 months,12 months and 24 months respectively after operation.and those in simple glaucoma valve implantation were 95.35％,71.43％,65.00％and 60.53％in corresponding time points,showing considerably significant differences between two groups (χ2=7.06,χ2=7.47,χ2=4.37,P<0.05).There was no significant difference in Ihe number of eyes with complication between the two groups(P>0.05). Conclusion The biological amnion combined with glaucoma valve implantation surgery may be more effective and safe for the treatment of neovascular glaucoma than with glaucoma va]ve only.
