Selective Laser Trabeculoplasty for Glaucoma Secondary to Emulsified Silicone Oil after Pars Plana Vitrectomy: A Pilot Study.

Background. To investigate the efficacy of selective laser trabeculoplasty (SLT) for lowering intraocular pressure (IOP) in patients with open angle glaucoma (OAG) secondary to emulsified silicone oil (SO). Methodology/Principal Findings. Prospective, interventional, consecutive case series of 11 eyes with sustained elevation of IOP after SO removal.The mean IOP at baseline, week 1, month 1, month 3, and month 6 was evaluated. The mean baseline IOP was significantly decreased from 25 ± 2.7mmHg to 18.4 ± 5.5mmHg at week 1 (ρ = 0.01), 17.9 ± 3.1mmHg at month 1 (ρ = 0.008), 15.8 ± 3.9mmHg at month 3 (ρ = 0.003), and 16.2 ± 4.7mmHg at month 6 (ρ = 0.004). IOP < 21mmHg was achieved in 91% of the eyes without a significant complication at month 6. Conclusion/Significance. SLT may be successful for lowering IOP in patients with OAG secondary to emulsified SO which was not controlled with maximum antiglaucomatous medical treatment. [ABSTRACT FROM AUTHOR]
