The Effect of Some Treatment Variables on the Results of Trabeculoplasty

The Effect of Some Treatment Variables on Long-Term Results of Argon Laser Trabeculoplasty

“…Randomisation was performed without seeing the patient, the laser power level was not changed regardless of the trabecular pigmentation or visible burn effect. The results o f this study have been published previously [17,18]. Sixty patients (65 eyes) could be obtained for re-examination 5 years after the first ALT.…”

“…The role of TM pigmentation in the production of elevat ed IOP in glaucoma is controversial, but several authors have found better results of ALT with more pigmented TM [9,18,22,23], The results presented here are similar in that 23 respect. The effect of pigment may be mediated by better absorption of laser light on pigmented TM.…”

Effects of Argon Laser Trabeculoplasty in the Early Manifest Glaucoma Trial

“…Considering the small number of eyes with exfoliation glaucoma in our material, it is obvious that non-significant findings might be explained by insufficient statistical power regarding exfoliation status. Many studies have shown that IOP reduction is larger in exfoliation glaucoma than in POAG, 2,5,19,22,32,38 even after performing multivariate analyses to correct for differences in pre-ALT IOP between these two types of the disease. 3 There is no agreement as to whether the pressure-lowering effect of ALT is influenced by trabecular pigmentation or pigmentation grade, 3 -5,22,24,37,38 and we found no significant impact of either of those aspects in our investigation.…”

Acute ultrastructural changes of the trabecular meshwork after selective laser trabeculoplasty and low power argon laser trabeculoplasty

“…To minimize coagulation damage following ALT variation of laser settings were studied and the same IOP lowering effect was achieved with smaller number of burns and less power (500 mW) and only half or less of the angle treatment [7][8][9]. Shirakashi et al [10] reported long term efficacy, applying low power (450 mW, 50 mm, 0.1 second) over 90-1208 of the TM.…”
