Abstract:
BACKGROUND:Currently,there are many studies concerning the pathogenesis,process,and damage of glaucoma,however,there is not an ideal glaucoma modelOBJECTIVE:To prepare rabbit intraocular hypertension models using three different material injections,and to verify the practical value of intraocular hypetension modelsMETHODS:Thidy New Zealand rabbits were divided randomly into 3 groups,with 10 animals in each group.One eye of each rabbit was served as the experimental eyes and the other eye as control eyes.Autoblood.methyl cellulose,C3F8 was injected into the anterior chamber of the experimental eyes.and the normal saline was injected into the control eyes.The intraocular pressure(IOP)was monitored prior to injection and at hours 0,24,36,48,72,96.120 and 168 after injection.RESULTS AND CONCLUSION:Intraocular hype Rension models could be induced by injecting 3 kinds of materials,and the IOP was obviously increased after injection(P＜0.05),and the ranges and periods of increasing were varied.The periods of increasing of 3 materials were 1,3 and 7 days,respectively,which could maintain for longer time for a second injection.The IOP ranged 1.86-6.65 kPa,and mild anterior segment inflammation could be found.The experiment demonstrated that intraocular hypeansion models using three different material injections are ideal models,which is characterized by simple,reliable and controllable.The suitable model can be selected for acute or chronic glaucoma research.
