Postural behaviour of intraocular pressure following trabeculoplasty.

Postural behaviour of intraocular pressure (IOP) was studied in 29 glaucomatous eyes before and after argon laser trabeculoplasty (ALT) and compared with that of 60 normal eyes. Although argon laser trabeculoplasty was successful in lowering the IOP below 21 mm Hg, it produced little effect on the postural behaviour of the IOP. No significant change was observed in the amplitude of postural rise of IOP in ALT treated eyes.
