Laser Trabeculoplasty in Glaucoma

Two‐year follow‐up of intra‐ocular pressure control with long duration argon laser trabeculoplasty

“…In the present report, an initial benefit for 0.2 second ALT in IOP control was found during the frrst year of follow-up, but this difference was not apparent during the second year. Both durations of ALT produced a similar fall in IOP to that in previous reports over a similar period of follow-up (Wise 1981;Pollack et al 1983;Sherwood et al 1987;Schwartz & Kopelman 1983;Schwartz et al 1985;Wise 1987;Shingleton et al 1987;Fink et al 1988;Ticho & Nesher 1989;Spaeth & Baez 1992). These were also similar to the two previous, retrospective studies of long duration ALT (Blondeau et al 1987;Hugkulstone 1989).…”

“…However, with longer follow-up it was found that an increasing number of patients lost the pressure-lowering effects of ALT (Schwartz & Kopelman 1983;Schwartz et al 1985;Wise 1987;Shingleton et al 1987;Fink et al 1988;Ticho & Nesher 1989;Spaeth & Baez 1992).

“…These were also similar to the two previous, retrospective studies of long duration ALT (Blondeau et al 1987;Hugkulstone 1989). However, there was no significant reduction in medications following ALT in t h i s study whereas others have achieved this, in a variable proportion of cases (Wise 1981;Pollack et al 1983;Schwartz & Kopelman 1983;Sherwood et al 1987;Wise 1987;Fink et al 1988;Ticho & Nesher 1989). Blondeau and colleagues (1987) also reported a small change in treatment scores at 2 years in their study of long duration ALT, as did my retrospective study (1989).…”

Long-term follow-up of laser trabeculoplasty

“…In the case of low tension glaucoma, deterioration of the visual field was the only factor that led to laser treatment. Some investigators took into account the number of anti-glaucomatous medications prescribed after LTP [4,14]. This number had to be equal to or less than the prelaser amount.…”

“…~< 19 or ~< 20 mmHg) and/or when the reduction in IOP was above a certain value (e.g. >~ 3 or ~> 4 mmHg) [4,6,12,14]. We accepted every reduction in IOP on the condition that the visual field and visual acuity showed no further deterioration on account of the glaucoma.…”
