To evaluate the safety and efficacy of pneumatic trabeculoplasty (PNT) in patients with primary open angle glaucoma (POAG).
28 eyes suffering from POAG under local medication of Latanoprost were enrolled in this prospective case series. At baseline intraocular pressure (IOP) ranged between 18 to 24 mmHg and was judged as to high in each case. Eyes were treated with PNT at day 0, 7 and 90, 180, 270. Assessments were performed 1 day, 4 weeks, 12 weeks after treatment includíng visual acuity, tonometry, slit-lamp and fundus examination, 30-2 perimetry and optical coherence tomography.
The mean IOP at baseline was 20.2 mmHg. Mean IOP at the last follow up was 17.4 mmHg. A mean decrease in IOP of 2.8 mmHg (P<0.01) was observed comparing the last IOP measurement with baseline IOP. The mean follow up is at 38,4 weeks. Beside conjunctival hyperemia and corneal epithelium disorder there were no unwished side effects in the treatment group. There were no significant change in VA, perimetry and RNFL thickness in both groups.
Pneumatic trabeculoplasty seems to be a safe and effective treatment to decrease IOP in patients suffering from POAG. Extended follow-up will be reported.
