Purpose To compare the effect of 90‐ and 360‐degree selective laser trabeculoplasty ( SLT ) as primary or supplement therapy in patients with glaucoma and ocular hypertension ( OHT ). Methods Patients (>30 years old) with OHT , primary open‐angle glaucoma ( OAG ), pigmentary glaucoma or pseudoexfoliative glaucoma were enrolled in a prospective randomized clinical trial. Patients were sequentially randomized to either 90‐ or 360‐degree SLT . Their intraocular pressure ( IOP ) was monitored. Results The survival periods (in days) of the two extents (90 or 360 degrees) of treatment were not statistically significantly different (p = 0.85); only pretreatment IOP level could predict survival of treatment (p = 0.02). Conclusion The 90‐degree SLT is as effective as 360‐degree SLT . Further studies are warranted to confirm the findings. High baseline IOP could be a factor that predicts treatment success.
