Abstract:
AIM: To investigate the effect of nitric oxide (NO) in ocular inflammation after intraocular lens implantation. METHODS: All New Zealand rabbits were divided randomly into three groups: 1. control group, 2. L-arginine (L-Arg) group, 3. N-nitro-L-arginine (L-NNA) group. Extracapsular cataract extraction (ECCE) and posterior chamber intraocular lens implantation (IOL) were operated in all animals of each groups. The inflammatory response of all rabbit eyes, including cornea edema and anterior chamber exudation were investigated 1, 3, 7, 14, 30 days afteroperation. Meanwhile, aqueous humor was drawn for white blood cell (WBC) counting and classifying, as well as for NO- 2/NO- 3 measurement. RESULTS:NO- 2/NO- 3 contents, total WBC and anterior chamber exudation in aqueous humor of L-Arg group were higher than that in control group. While that of L-NNA group were lower than that in control group.CONCLUSION:NO plays a role in intraocular inflammatory response after intraocular lens implantation. L-NNA, a nitric oxide synthase exhibitor, decreased NO contents, therefore it may reduce intraocular inflammatory response after intraocular lens implantation.
