Difference Of The Intension Of Incision Between Corneal Tunnel Incision And Sclera Tunnel Incision And The Study In Histopathology

PurposeContrapose the fact that the probability of intraocular infection in the group of transparent corneal tunnel incision is higher than that of sclera tunnel incision both in phacoemulsification Aspiration. Pressurize test is developed in this paper, and has a continues 5 weeks -5 times observation of pathology slice. To compare the capability of self - atresia and intension in the 2 methods, then make the conclusions.Methods20 rabbits with the same genus, sex and similar weight were randomly divided into A,B group to have a comparison. Group A is transparent corneal tunnel incision group while Group B is sclera tunnel incision group. Right eyes were treated as standard PEA, pre - &after - operation management. After general anaesthesia, operate standard transparent corneal tunnel incision and sclera tunnel incision. Then anterior chamber ultrasonic ( energy 50% , minus pressure 300mmHg,time 30s) ,3rd day,7th day,2nd week,5th week after -operation, process local pressurize test under microscopic florescent dye, observe the instance of leakage. Choose a rabbit randomly from each group when the 1st ,2nd ,3rd ,4th ,5th week afer - operation, extirpate the right eyeball, make pathology slices of the incision. Observe, photograph and note. Then make statistical management. Use chi square test to check the result of pressurize test. ( fourfold data fisher's exact test )...
