AIM: To investigate the efficacy of selective laser trabeculoplasty(SLT)for lowering intraocular pressure(IOP)in patients with emulsified- silicone oil related secondary open angle glaucoma(SO-OAG).

METHODS: By a retrospective case study, consecutive case series of 120 eyes with sustained elevation of IOP after SO-OAG removal were treated by 360° SLT treatment. The mean IOP, mean number of glaucoma medications, and success rates at baseline 1wk, 1mo, 3mo were evaluated.

RESULTS: After the SLT treatment, the mean baseline IOP was significantly decreased from 25.02±5.93mmHg to 17.64±4.52mmHg at 1wk(P=0.002), 18.96±3.33mmHg at 1mo(P=0.04), and 18.03±5.69mmHg at 3mo(P=0.03). The mean number of glaucoma medications significantly decreased from 3.11±0.62 to 1.78±0.14 at 1wk(P=0.006), 1.95±0.56 at 1mo(P=0.04), and 1.87±0.53 at 3mo(P=0.02). The complete and qualified success rate were 68.3%(82 eyes)and(20.0%)(24 eyes)at 1wk, 61.7%(74 eyes)and 17.5%(21 eyes)at 1mo, and 64.2%(77 eyes)and 12.5%(15 eyes)at 3mo.

CONCLUSION: SLT may be effective for lowering IOP in patients with SO-OAG which was not controlled with maximum antiglaucomatous medical treatment.
