Primary lasertrabeculoplasty a comparison of 50 spots in 180 degrees and 100 spots in 360 degrees of the trabecular meshwork.
Primary LTP was performed in 20 eyes with 50 spots in 180 degrees and in 26 eyes with 100 spots in 360 degrees of the trabecular meshwork. These eyes had received no earlier glaucoma medication. They were followed prospectively for 12 months. Prelaser IOP was 36.3 +/- 8.0 mmHg in the 50 spot group and 35.9 +/- 6.6 mmHg in the 100 spot group. Treatment was considered successful if IOP was less than or equal to 22 mmHg with no medication and no further disk damage or loss of visual field. The success rate 12 months after LTP was 15% in the 50 spot group and 69% in the 100 spot group.
