Abstract:
Objective To study the correlation between the rabbit glucocorticoid receptor(GR) and steroid-induced glaucoma(SIG).Methods The GR binding in peripheral blood leukocytes and plasma cortisol were measured in 15 adults pigmented rabbits on the first day of experiment, 0.5mg dexamethasone was injected in the right eyes of each rabbit once every 2 days, totally 15 times for 30 days. Right eyes intraocular pressure(IOP) and aqueous outflow facility were measured every week, the relation between GR, plasma cortisol, IOP and aqueous outflow facility(C) was analyzed. Results After the experiment the IOP increased by 0.67kPa±0.49kPa(P＜0.01),C decreased by 0.08±0.11(P＜0.01).GR may closely be related to IOP and C(r=0.56,P＜0.025; r=0.60,P＜0.01).Plasma cortisol was independent of IOP and C(r=0.27, P＞0.05;r=0.34,P＞0.05).Conclusion The level of GR has positive correlation with the sensitivity of tissue of eye to glucocorticoid.
