To evaluate the short(1 month) and middle term (6 months) effect of selective laser trabeculoplasty (SLT) in pigmentary glaucoma (PG).
The authors retrospectively analysed results of SLT in 32 eyes of 32 patients: included 15 in the PG group versus 17 in the Primitive open angle glaucoma (POAG) group.SLT was performed on 32 eyes of 32 patients between november 2010 and May 2011,treatment was applied to anterior trabecular meshwork for 220°.The IOP was measured at 1 hour after treatment, 1 month and at 6 months after laser treatment. We then compared the results of the two groups.
There was significant statistical differences between the two groups in relation to age factor : 43,6 +/- 11,4 years in the PG group versus 66,3 +/- 12,9 years in the POAG group, gender : 73,33 % of men in the PG group versus 76,47% of women in the POAG group, and the decrease of IOP at a 6 month period after treatment : 0,7 +/- 3,5 (3,8%) in the PG group versus 2,75 +/- 2,1 (15.5%) in the POAG group.
In our study, selective laser trabeculoplasty is less effective in pigmentary glaucoma than in Primitive open angle glaucoma at 6 months after laser treatment.
