目的 :探讨准分子激光角膜切削术 (PRK)后应用不同皮质类固醇激素高眼压的发生情况。方法 :将 84 6例13 98眼PRK术后分A( 2 5 6眼 )、B( 4 3 1眼 )、C( 70 7眼 )三组 ,分别使用 0 .5 %醋酸可的松、0 .1%地塞米松、0 .1%氟甲松龙 (FML) 4～ 5月。结果 :激素性高眼压的发生率为 7.1% ( 99眼 )。A、C组高眼压的发生率 ( 1.95 %、1.84 % )较B组 ( 18.80 % )低。高度近视眼中高眼压的发生率 ( 10 .9% )明显高于中低度近视 ( 5 % )。结论 :RPK术后合理选择用药可以减少激素性高眼压的发生 ,并应加强对PRK术后病人 ,特别是高度近视患者的眼压的观察和随访。
Objective: To investigate the application of different corticosteroid intraocular pressure after excimer laser keratectomy (PRK). Methods: A total of 846 PRH patients with 1398 eyes were divided into three groups: A (2.56 eyes), B (431 eyes) and C (707 eyes). The patients were treated with 0 .5% cortisone acetate, .1% dexamethasone, 0.1% fluorometholone (FML) from April to May. Results: The incidence of steroid-induced ocular hypertension was 7.1% (99 eyes). The incidence of ocular hypertension in group A and group C (1.95%, 1.84%) was lower than that in group B (18.80%). The incidence of high intraocular pressure in high myopia (10.9%) was significantly higher than that of moderate to low myopia (5%). CONCLUSIONS: Rational choice of medication after RPK can reduce the occurrence of steroid-induced ocular hypertension and should strengthen the observation and follow-up of intraocular pressure in post-PRK patients, especially those with high myopia.
