Objective To evaluate the clinical efficiency of fresh amniotic membrane transplantation in treatment of stenosis of conjunctival sac. MethodsThirty cases (30 eyes) of stenosis of conjunctival sac were treated with fresh amniotic membrane transplantation. Amniotic membrane was obtained under sterile conditions after elective cesarean delivery. The woman’s serum was negative for HBsAg, syphilis, and human immunodeficiency virus. The placenta was first washedfree of blood clots with sterile saline. Under sterile conditions, the inner amniotic membrane was separated from the chorion by blunt dissection, and was cleaned of blood with the sterile saline again. The membrane was then flattened onto a surgidrape adhesive paper with the epithelium surface up. The paper with the adherent amniotic membrane was then cut into 5 cm×8 cm pieces, and then rinsed in solution containing 4×106 U/L of gentamycin and stored at 4℃. It could bestored for 12 hours after preparation. The-adhesiotomy was performed firstly. The separation between the conjunctiva and scar tissue should be complete and wide enough to reach to the orbital margin. The adhesiectomy was taken secondly. The scar tissues were removed completely. The fresh amniotic membrane was flattened onto the conjunctival defect with epithelium side up. The fresh amniotic membranewas 10 mm more than the conjunctival defect by trimming off the excess portion.This fashioned membrane was then secured to surrounding conjunctival edge with continuous 7-0 nylon sutures. The necessary mattress suture of inferior conjunctival fornix via skin next to the inferior orbital margin was performed simultaneously. The retrobular implantation of the an artificial globe made of hydroxyapatite was performed on some patients with sunken eye. Correction of traumatic ptosis was performed on a few patients.Results The operation ofreconstruction of partial conjunctival sac for 30 cases was successful. All amniotic membrane grafts were alive. The cosmetic result was complete favorable. The infection and contracture of the graft, immunologic rejection and amniotic lysis were not observedin all cases during the follow-up period of 13-18 months.Conclusion Fresh amniotic membrane transplantation can be used in reconstruction of the partial conjunctival sac effectively and can be popularized in thelocal hospital in China because the amniotic membrane can be obtained easily.
PURPOSE:To evaluate the value of the apoptosis-suppressing oncogene bcl-2 protein expression in the development and progression of uveal and conjunctival melanomas. METHODS:Using flow cytometry and immunofluorescence methods to detect the bcl-2 protein expression in 40 cases of uveal malignant melanomas (UMM), 5 cases of conjunctival nevi (CN) and 7 cases of conjunctival malignant melanomas (CMM). RESULTS :The expression content of bcl-2 protein in CMM was significantly higher than that in CN (P<0.05);the bcl-2 protein positive expression percentages in CMM and UMM were 85.71% and 72.50% respectively. The expression content of bcl-2 protein in UMM was not related to pathological classfication, scleral invasion,ciliary body involvement,and tumor dimensions (P>0.05). CONCLUSIONS: The over-expression of bcl-2 protein and apoptosis suppressing might be related to the pathogenesis of CMM and UMM;bcl-2 protein expression might be helpful in discriminating CN from CMM, but unavailable in evaluating the patholgical malignancy of UMM.

We compared the sensitivities of human embryo conjtmctival fihroblasts(HECF)and rabbit conjunctival fibroblasts(RCF)m five anlineoplasties in vitro.When the concentration of vincrismum and doxorubicin was 0.001~10mg/L.5-FU was 1~1000mg/L and cisplatin was 0.01~10mg/L,the sensitivities of HECF to tile drugs were lower than that of RCF (Plt;0.01).while the difference of the sensitivilics be;ween HECF and RCF to VP-16 was not significant (P<0.05). The results suggested that the selection of therapeutic agents for intraocular proliferative disease wilh'hunmn conjunctiva fihroblasts may be more valuable than that with RCF.

Methods The clinical data of 160 patients with cataracts between January 2007 and December 2010 were collected. The patients were randomly divided into two groups with 80 patients (160 eyes) in each group. The patients in group A underwent the small-incision choper ECCE surgery with non-conjunctival flaps; while the patients in group B underwent the traditional conjunctival flaps. Then the total effective rate, incidence of complications, and satisfaction rate of the two groups were analyzed and compared. Results One month after the surgery, the comfort was found in 154 eyes (96.25%) in group A and in 141 eyes (88.13%) in group B; the difference was significant (χ2=7.332,Plt;0.05). The complications after the surgery including conjunctiva retraction, nutation, and huge scar were found in 7 eyes (4.38%) in group A and in 29 eyes (18.13%) in group B, and the difference was significant (χ2=15.149,Plt;0.01) . The visual acuity of the patients one day, one week and one month after the surgery in the two groups were: one day: 120 eyes (75.00%) in group A and 128 eyes (80.00%) in group B (χ2=1.467,Pgt;0.05); one week: 130 eyes (81.25%) in group A and 132 eyes (82.25%) in group B (χ2=0.084,Pgt;0.05); one month: 138 eyes (86.25%) in group A and 139 eyes (86.86%) in group B (χ2=0.027,Pgt;0.05). The cornea edema was alleviated half month after the surgery. Conclusion Compared with the traditional way, non-conjunctival flaps ECCE may save the surgical time, reduce the damage of the ocular surface, improve the visual acuity and received higher satisfaction rate and less conjunctive complication, which is a good surgical method in local hospital.
