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.

·AIM: To study the expressive variation of Nogo-A on rat retina in the process of chronic ocular hypertension. · METHODS: Thirty-six healthy adult male Wistars were randomly divided into control group (6 rats) and chronic hypertension group (30 rats). Chronic hypertension was created by cauterizing the superficial scleral veins. Immunohistochemistry technique was used to evaluate the expressive varieties of Nogo-A at different time points during the course of chronic ocular hypertension. · RESULTS: The success of the model was indicated by over 40% of increase in the IOP as compared with normal rats. Compared with control group, as time passed chronic hypertension group gradually had detectable morphology changes in the retina. At the 21st day of chronic ocular hypertension, retinas became thinner and the quantity of retinal ganglion cell (RGC) decreased (P<0.05). Assoicated with the morphological changes, the expression of Nogo-A was strongly increased (P<0.05).CONCLUSION: Myelin associated protein Nogo-A plays a part in the process of chronic ocular hypertension.

AIM:To compare one-site vs two-site phacotrabe-culectomy in chronic angle-closure glaucoma (CACG) coexisting with cataract.METHODS:This prospective, randomized study included 41 eyes with CACG. One-site approach was performed in 21 eyes and two-site procedure in 20 eyes. Intraocular pressure (IOP), best-corrected visual acuity (BCVA), the number of antiglaucoma medications and complications were observed. All patients were followed up for 9 months.RESULTS:There were no significant differences between the two groups preoperatively. IOP decreased from 22.7±4.9mmHg and 23.7±4.7mmHg preoperatively in one-and two-site groups to 18.0±1.2mmHg and 16.7±1.1mmHg 9 months after operation respectively(P<0.05). There were no significant differences in mean IOP between the two groups at any time (P>0.05). Decrease of the number of antiglaucoma medications and BCVA improvement were similar in both groups 9 months after surgery (P>0.05).There were no significant differences in complications between the two surgical procedures.CONCLUSION:There were no significant differences between the two groups in clinical efficacy and complications.

?AIM: To evaluate the effect for refractory glaucoma by using Ex - Press miniature implantation with deep sclerectomy.?METHODS: Thirty eyes in 24 patients with refractory glaucoma were treated by Ex- Press miniature ( P50 ) implantation with deep sclerectomy. The patients’ symptom, intraocular pressure ( IOP ) , visual acuity and complications were analyzed in a 12mo follow-up period.?RESULTS: During the follow-up period, all patients’ ocular pain was reduced. The mean IOP before operation and at the last follow-up time were 51. 15 ± 2. 60mmHg (1kPa=7. 5mmHg) and 15. 11 ± 2. 51mmHg, respectively, there was significant difference (P<0. 05). Postoperative visual acuity was improved in 8 eyes, had no significant change in 22 eyes. After operation, hyphema of anterior chamber appeared in 2 eye ( 7%) , which were obsorbed after 1wk.? CONCLUSION: Ex - Press miniature implantation combined with deep sclerectomy surgery is a relatively effective and safe treatment for the patients with refractory glaucoma. This method can significantly degrade the IOP, lessen ocular pain and reduce the complications risk.
