Abstract:
Background Glucocorticoid drugs have been used increasingly in ophthalmology.It has been established that glucocorticoid are associated with a rise in intraocular pressure (IOP) and the development of glaucoma.Selective laser trabeculoplasty (SLT) is thought to be effective in treating patients with glucocorticoidinduced elevated IOP.Objective This study was to assess the efficacy of SLT in lowering IOP in patients with glucocorticoid-induced ocular hypertension.Methods A retrospective case series study was adopted.SLT around 360° chamber angle was performed in 9 eyes of 9 patients with glucocorticoid-induced glaucoma in Eye & ENT Hospital of Fudan University,including 5 eyes of 5 patients owing to use of glucocorticoid eye drops for long-term after laser in situ keratomileusis (LASIK) and 4 eyes of 4 patients who received intravitreal injection of 0.1 ml triamcinolone acetonide (TA) (4.0 mg) for macular edema induced by central retinal vein occlusion(CRVO).All of the patients were lack of preexisting glaucoma or ocular hypertension and underwent unsuccessful maximum tolerated medical therapy before SLT treatment.The base IOP was 35-44 mmHg and glucocorticoid drugs were ceased for 2-12 months prior to the SLT.The patients were followed-up for 6 months.IOP was measured and recorded before and 1 hour,1 week,1 month and 3 months,6 months after SLT.The difference of IOP was compared by repeated measures analysis of variance and multiple comparison analysis.Results All the patients received single SLT operation.The mean IOP was (40.0±2.9) mmHg before operation,but the IOP was (37.9±8.1),(34.9±5.9),(27.6±6.7),(21.6±6.9) and (17.9±2.9)mmHg 1 hour,1 week,1 month,3 months and 6 months after SLT.The IOP at 1 month,3 months and 6 months after SLT were significantly lower than that before operation (all at P＜0.05).Two patients received a filtration surgery for uncontrolled IOP at 1 month and 3 months after SLT respectively,and another patient still used 2 kinds of lowing-IOP eye drops until the end of following-up duration.Conclusions SLT reduce IOP in 6 eyes of 9 patients with glucocorticoid-induced increased IOP from the initial 1 month through 6 months after SLT.
