Purpose: To determine the effect on intraocular pressure (IOP) of Selective Laser Trabeculoplasty (SLT) in patients with increased IOP secondary to intravitreal steroid injection. Methods: In a prospective study, patients with elevated IOP after intravitreal steroid injection who were evaluated by the authors underwent SLT by one of the authors (RMC) in the affected eye. Patient information included: age, gender, and race. The type, amount, and date of the intravitreal steroid injection were recorded. The date and the settings of the SLT were noted. IOP and the number of glaucoma medications both pre–operative and post–operative were documented. Results: Eight eyes of seven consecutive patients underwent 1 to 3 SLT’s. Mean patient age was 56.9±6.2(S.E.) years (range:29 to 84 yrs). 1(12%) was female, 7(88%) were male. All were white. The intravitreal steroid injection consisted of 0.1 cc of 40 mg/cc (4 mg) of triamcinolone. The average SLT settings were power: 1.01±0.1(S.E.) Mj., Application #: 67.1±2.9(S.E.), Total Energy: 66.2±3.8(S.E.). The average follow–up was 5.25±1.5(S.E.) months (range:1.25 to 13.25 m.). The average change in IOP was –12.2±4.6(S.E.) mm. Hg. (range:+3.0 to –36.0 mm. Hg.). The average IOP was 38.1±3.3(S.E.) pre–SLT and 25.3±3.4(S.E.) post–SLT (p<0.01,t–test). The average number of glaucoma medications was 3.8±0.2(S.E.) pre–SLT and 3.6±0.2(S.E.) post–SLT (p>0.3,t–test).Conclusions:SLT may be an effective treatment modality in the management of steroid induced ocular hypertension caused by intravitreal steroid injection. Multiple procedures may be necessary to obtain a successful IOP lowering effect.
