AIM: To investigate the clinical effectiveness of reformed nonperforating trabeculectomy (NPT) in the patients with primary glaucoma.METHODS: 30 eyes of 21 patients with primary glaucoma patients underwent reformed NPT, in which 1.0mm3.0mm out layer of trabecular meshwork with Schlemm's canal was excised, but the innermost tissue was reserved. The clinical effectiveness was observed with short-term follow-up (1wk;1,6mo) and the long-term follow-up (1a and over, 10a the longest).RESULTS: The intraocular pressure (IOP) was controlled in 28 eyes (93%) without anti-glaucoma medicine during short-term follow-up, and in 27 eyes (90%)for long-term ones. There were no serious post-operative complications in all cases.CONCLUSION: The elevated IOP in patients with primary glaucoma can be effectively reduced by reformed NPT during short-term and long-term follow-up. The post-operative complications are much less because of no intra-operative penetration of the anterior chamber. The reformed NPT is an ideal surgical procedure for primary glaucoma.

AlM:To observe the effects of double incision combined surgery of single - stab trabeculectomy and phacoemulsification.
METHODS: Totally 28 cases ( 30 eyes ) with glaucoma and cataract undertook the modified combined surgery of single - stab trabeculectomy and phacoemulsification. After traditional phacoemulsification, cut the bulbar conjunctiva and Tenons capsule from the 11 o'clock to 1 o'clock, then puncture into the anterior chamber in 2mm behind the corneal limbus with 3mm tunnel knife, shaping a 3mm wide, 1/3-1/4 thickness scleral tunnel. Getting into the trabecular tunnel, bite off 3 pieces of trabecular tissue about 1mm × 1mm size. The changes in the imtraocular pressure ( lOP ) and the visual acuity before and after the surgery as well as filtering bleb ( OCT confirmed) and complications were carefully observed in 3-6mo postoperatively.
RESULTS: The postoperative visual acuity in 1wk postoperatively less than 0. 1 was found in 3 eyes, from 0. 1 to 0. 3 was found in 6 eyes,from 0. 3 to 0. 6 in 13 eyes, from 0. 6 to 0. 8 in 8 eyes. One eye had malignant glaucoma, and 8 eyes had cornea edema and slightly fibrin exudation in the pupil area; ln all cases maintained function conjunctival blebs of filtering, OCT confirmed this. lOP remained normal in 28 eyes in 3-6mo follow up, lOP of 2 other eyes could be controlled by anti-glaucoma eye drops.
CONCLUSlON:Double incision combined surgery of single- stab trabeculectomy and phacoemulsification is effective and safe, reduces the postoperative complications and is worthy of promotion.

Background Neurofilament 200 (NF200) is an indirect indicator of the specific distribution of axons.It reflects the condition of the maintenance of neuronal morphology.Whether NF200 is involved in the damage of the visual pathway after retinal ischemia reperfusion injury (RIRI) should be further examined.Objective The present study was to investigate the expression of NF200 in retinal ganglion cells (RGCs),lateral geniculate nucleus (LGN),superior colliculus and visual cortex following RIRI.Methods Forty SD rats were randomized into the RIRI 1-,2-,3-,4-,6-,8-week groups,sham operation group and control group.Acute intraocular hypertension was induced in the right eye by anterior chamber perfusion of normal saline solution for 60 minutes to elevate the intraocular pressure to 110 mmHg.The animals were sacrificed at different time points for the preparation of the retina,LGN,superior colliculus and visual cortex sections.The expression of NF200 in RGCs,LGN,superior colliculus and visual cortex was assayed by immunohistochemistry.Results The expression level (A value) of NF200 in the RGCs was significantly different among the 8 groups after reperfusion (F =78.855,P =0.000),and that in the 1-week group was significantly lower than in the control group (t =36.563,P＜0.01).In the RIRI 1-week group,the expression of NF200 in the contralateral LGN in the experimental group was significantly lower than that in the control group (t =6.483,P＜0.01).In the 4-week group and 6-week group,the expression of NF200 in the contralateral LGN was significantly higher than that in the control group (t =2.904,4.313,P＜0.01).One week after RIRI,the expression of NF200 in contralateral superior celliculus in the experimental group was significantly lower than that in the control group (t =2.966,P＜0.05),and in the 2-week group,the expression of NF200 in the contralateral superior colliculus was significantly higher than that in the control group (t =7.397,P＜0.01).In the 2-week group,3-week group and 4-week group,the expression of NF200 in bilateral visual cortex was significantly higher in the experimental group than that in the control group (contralateral ∶ t =18.728,18.213,15.088,P＜0.01 ; ipsilateral ∶ t =8.690,5.704,7.805,P＜0.01).Conclusions RIRI can induce axonal damage of RGCs,contralateral LGN,superior colliculus and bilateral visual cortex neurons.

Abstract?AlM: To investigate the effect of zebularine ( Zeb ) loaded Poly ( ethylene glycol ) - block - poly ( ε -caprolactone) methyl ether ( MePEG-PCL) nanoparticles ( NPs) on the viability, attachment, and apoptosis of in vitro cultured lens epithelial cells ( LECs) .?METHODS: In vitro cultured infant human lens tissue HLE B-3 immortalized cells were distributed randomly divided into six groups. Each group was administered with free Zeb 50μmol/L ( ZebF1 group ) , 100μmol/L ( ZebF2 group) , Zeb -loaded MePEG-PCL NPs 50μmol/L ( ZebNP1 group) , Zeb -loaded MePEG-PCL NPs 100μmol/L ( ZebNP2 group) , MePEG-PCL empty NPs( NPs group) or blank medium (group C) respectively. A tetrazolium dye assay ( MTT) test and modified MTT test were performed to determine cell viability and cell attachment. DNA ladder was used to detect the cell apoptosis.?RESULTS: Determined by MTT colorimetric method:Cell proliferation rate of LECs were suppressed by all Zeb administration groups in a concentration-time dependent manner (P<0. 05). Compared with the free Zeb groups, the viability of LECs were suppressed more effectively by the same dose of Zeb loaded MePEG-PCL NPs after 24, 48, 96h ( P < 0. 05 ). Determined by improved MTT colorimetric method: The attachment of LECs were decreased in all Zeb administration groups, Zeb loaded MePEG-PCL NPs had better effect on suppressing the attachment of LECs than the free Zeb groups with same dose (P<0. 05). The DNA ladder confirmed that after administration of 96h, group C, NPs group and ZebF1 group showed no DNA fragment, however the DNA fragment were performed in ZebF2, ZebNP1, ZebNP2 groups and displays the trend of ZebNP2> ZebNP1>ZebF2 (P<0. 05).?CONCLUSlON: Zeb loaded MePEG-PCL NPs had better effect on suppressing the viability and attachment of in vitro cultured LECs than the free Zeb groups , as well as enhancing the apoptosis.
