放射狀角膜切開術術後併發類固醇性青光眼

Steroid-induced Glaucoma after Radial Keratotomy-2 Cases Report

摘要


本篇報告兩例接受放射狀角膜切開術(Radial keratotomy)女性病人於追蹤期間因視力波動(Visual acuity fluctuation)長期使用皮質性類固醇點眼劑(0.1% Dexamethasone)而併發續發性隅角開放性青光眼。兩例都有漸進性之視神經盤凹陷變大及視野缺損,同時眼壓均無法以藥物控制。因此兩例都接受鐳射小樑網整型術(Laser trabeculoplasty)。病例一鐳射後眼壓控制良好;病例二接受鐳射二尖失敗後,實施小樑網切除術(Trabeculectomy)。

We reported 2 cases of steroid-induced glaucoma after radial keratotomy. The 2 patients used topical corticosteroid eyedrop for a period of time. Intraocular pressure elevated, disc cupping enlarged and visual field defect were noted in both cases. Laser trabeculoplasty was done. The intraocular pressure of case 1 returned to normal after laser procedure. Case 2 received additional trabeculectomy followed the failure of 2nd laser trabeculoplasty. We found there is a close relationship between visual acuity and intraocular pressure of those cases of undercorrection after radial keratotomy.
