RESUMEN
Objective:To evaluate pediatric cataract operative cases,especially traumatic cataract patients,through operative skill,intraoperative complications and their managements,postoperative vision and complications.Methods:108 eyes of 82 pediatric patients,who were diagnosed as developmental,congenital,traumatic,and after-cataract with age ranged from 2 to 14 years old,were performed cataract extraction combining with intraocular lens implantation.Analysis were carried out based on postoperative vision,intra-postoperative complications and managements.Results:102 eyes got better vision postoperatively than before.Main intraoperative complications were posterior capsular rupture and prolapse of vitreous,and main postoperative complications were posterior capsular opacity(PCO),inflammatory reaction of anterior chamber,etc.Conclusion:Cataract extraction combining with intraocular lens implantation through sclera tunnel incision is an effective method for the pediatric patients whose age was over 2 years old.There exists special postoperative complications in pediatric patients and appropriate managements at the right moment ensure satisfactory effects.
RESUMEN
Objective:To study the changes of cytochrome oxidase (CO) activity in retina of monocular deprived rats.Methods:Deprived amblyopia rat model were established by suturing the eyelids of observed eye of 14 days old rats for one month.The retina stretched preparation were processed with CO histochemical reaction and the number of CO positive retina ganglion cells were studied under light microscope.Results:The number of CO positive retina ganglion cells decreased in deprived eyes compared with control eyes( P
RESUMEN
AIM: To explore the inhibitory effect of honokiol on retinal NV. METHODS: Hyperoxia was induced in NV model in 60 mice.Twenty mice received an intraperitoneal injections of 100 mg/kg honokoil twice daily for 5 days as large-dosage group and 20 mice received 50 mg/kg as small one while 20 mice received BSS as control.The collagen IV immunohistochemical staining was used to observe retinal vessels.The effect was evaluated by counting the nuclei extending from retina to vitreous and expressions of VEGF and MMP-2. RESULTS: The reduced density of vessels in the treatment group were found in retinal.The number of nuclei was less in the treated groups,which in the lagre-dosage group was significantly less.The expressions to VEGF and MMP-2 were less in the treatment than in the control respectively.That in the large-dosage group was significantly less. CONCLUSION: Intraperitoneal injections of honokoil can effectively inhibit retinal NV,depending on dosage.

(0.05)).And there were no side effects in two groups. CONCLUSION: The Yinqiao Tablet is effective and safety in treating wind-type common cold.
RESUMEN
Objective:To investigate the operative skill of phacoemulsification for cataract patients,to explore the best access at early learning stage and to study the related complications.Methods:Learning included attending lectures (theoretical study),animal experiments and case selections.97 consecutive cases(100 eyes) of early stage patients underwent phacoemulsification under peribulbar anaesthesia,continuous curvilinear capsulorhexis(CCC)or open capsulotomy,hydrodissection or hydrodelineation,one or two had nuclear phacoemulsification and IOL implantation.Results:During the first and second half of learning stage,CCC were performed successfully in 38%and 74% of the cases respectively;furthermore the incidences of posterior capsuletearing were 30% and 12% respectively.63 eyes (53%) with postoperative corrected visual acuities over 0.5 were observed. Conclusion:CCC method with maintenance of anterior chamber and emulsification within capsule must be adopted,furthermore posterior capsule tearing and corneal edema should be prevented.Phacoemulsification could be a safe procedure even during the learning curve by means of learning step by step,training followed an appropriate programme,selecting the suitable cases and managing complications correctly.The successful transition to phacoemulsification would be completed.
RESUMEN
Objective:To study the operative skill and clinical outcome of double eyelid operation on the treatment of various upper eyelid entropion and trichiasis.Methods:330 patients (640 eyes)with various upper eyelid entropion and trichiasis underwent modified double eyelid operation combining with correction of entropion.Results:There were 313 satisfactory cases(94.85%),14 improved cases(4.21%),and only 3 ineffective cases(0.91) obtained from follow-up.Conclusion:It is suggested that modified double eyelid operation not only can treat eye disorders through correcting upper eyelid entropion and trichiasis,but get good plastic effects as well.
