Résumé
BACKGROUND: Selective laser trabeculoplasty (SLT) is a relatively new treatment strategy for the treatment of glaucoma. Its principle is similar to that of argon laser trabeculoplasty (ALT), but may lead to less damage to the trabecular meshwork. METHODS: We assessed the 2-year efficacy of SLT in a noncomparative consecutive case series. Any adult patient either suspected of having glaucoma or with open-angle glaucoma, whose treatment was judged insufficient to reach target intraocular pressure (IOP), could be recruited. IOP and number of glaucoma treatments were recorded over 2 years after the procedure. RESULTS: Our sample consisted of 44 consecutive eyes of 26 patients, aged 69+/-8 years. Eyes were treated initially on the lower 180 degrees . Three of them were retreated after 15 days on the upper 180. Fourteen eyes had ocular hypertension, 17 primary open-angle/normal-tension glaucoma, 11 pseudoexfoliation (PEX) glaucoma, and two pigmentary glaucoma. Thirty-six eyes had previously been treated and continued to be treated with topical anti-glaucoma medication, ten had had prior ALT, nine iridotomy, and 12 filtering surgery. The 2-year-follow up could not be completed for eight eyes because they needed filtering surgery. In the remaining 36 eyes, IOP decreased by a mean of 17.2%, 3.3 mmHg, (19.2+/-4.7 to 15+/-3.6 mmHg) after 2 years (p<0.001). As a secondary outcome, the number of glaucoma treatments decreased from 1.44 to 1.36 drops/patient. Other results according to subgroups of patients are analyzed: the greatest IOP decrease occurred in eyes that had never been treated with anti-glaucoma medication or with PEX glaucoma. SLT was probably valuable in a few eyes after filtering surgery; however, the statistical power of the study was not strong enough to draw a firm conclusion. When expressed in survival curves after 2 years, however, only 48% and 41% of eyes experienced a decrease of more than 3 mmHg or more than 20% of preoperative intraocular pressure, respectively. CONCLUSION: SLT decreases IOP somewhat for at least 2 years without an increase in topical glaucoma treatment. However, it cannot totally replace topical glaucoma treatment. In the future, patient selection should be improved to decrease the cost/effectiveness ratio.
