目的 :分析准分子激光角膜切削术 ( PRK)治疗近视术后激素性高眼压的发生及预后。方法 :回顾性分析近视度数在 - 1 .75D到 - 1 9D的 91眼的激素性高眼压的发生及治疗情况 ,并与对照组做比较。结果 :激素性高眼压的发生率为 3.88% ,眼压升高多发生于术后 2月 ,男性多于女性。眼压升高时平均眼压 3.87± 0 .74k Pa,治疗后在 1 2 .2 3± 7.39d内眼压恢复正常。术后最后一次随访时裸眼视力为 1 .1 2± 0 .34( 0 .2～ 1 .5) ,剩余屈光度为 - 0 .61± 1 .1 0 ( - 3.50～ + 1 .2 5) DS。眼压升高组与对照组相比术前平均眼压高 ,角膜较厚 ,角膜屈光力较平坦。结论 :定期术后随访可及时发现激素性高眼压 ,治疗后不影响视力预后。术前认真筛选可疑病人和修订激素性青光眼的诊断标准有助于提高 PRK的安全性
Objective: To analyze the occurrence and prognosis of steroid-induced ocular hypertension after excimer laser keratectomy (PRK). Methods: The occurrence and treatment of steroid - induced ocular hypertension in 91 eyes with myopia ranging from -175D to - 1 9D were retrospectively analyzed and compared with that of the control group. Results: The incidence of steroid-induced ocular hypertension was 3.88%. The increase of intraocular pressure occurred more frequently in February than in the postoperative period. There were more males than females. The intraocular pressure (IOP) was 3.87 ± 0.74kPa when IOP was raised, and intraocular pressure returned to normal within 12.23 ± 7.39d after IOP. The visual acuity of the uncorrected eyes at the last follow-up was 1.12 ± 0.34 (0.2-2.5) and the remaining power was -0.61 ± 1.10 (-3.50 ± 1.52) DS . Compared with the control group, the intraocular pressure (IOP) increased preoperative mean intraocular pressure (IOP), corneal thickening and corneal refractive power were more flat. CONCLUSION: Hypertensive intraocular hypertension can be found timely and regularly after operation, and does not affect the prognosis of vision after treatment. Preoperative careful screening of suspicious patients and revision of diagnostic criteria for steroid-induced glaucoma help to improve the safety of PRK
