Intraocular pressure response to selective laser trabeculoplasty in the treatment of primary open-angle glaucoma
Gracner TOphthalmologica 2001; 215: 267-270
PURPOSE: To evaluate the intraocular pressure (IOP) response to selective laser trabeculoplasty (SLT) in the treatment of uncontrolled primary open-angle glaucoma (POAG), in a prospective clinical study. SLT is a new laser procedure that selectively targets trabecular meshwork (TM) cells without coagulative damage to the TM. METHODS: Fifty eyes with uncontrolled POAG were treated with a frequency-doubled, Q-switched Nd:YAG laser (532 nm). A total of approximately 50 nonoverlapping spots were placed over 180 ° of the TM at energy levels ranging from 0.40-0.92 mJ/pulse. After SLT, the eyes were maintained with the identical hypotensive medical therapy as that before treatment. IOP was estimated before and one and seven days, and one, three and six months after treatment. RESULTS: The mean pretreatment IOP was 22.48 mmHg (SD, 1.84). At the end of one month of follow-up, IOP was reduced by a mean of 4.86 mmHg (SD, 2.38), or 21.6%; after three months, IOP was reduced by a mean of 5.66 mmHg (SD, 2.40) or 25.2%; at the end of six months of follow-up, IOP was reduced by a mean of 5.06 mmHg (SD, 2.37) or 22.5%. CONCLUSION: SLT is an effective method of lowering IOP in the treatment of POAG.
