Cyclocryotherapy versus transscleral diode laser cyclophotocoagulation for uncontrolled intraocular pressure.

Abstract

BACKGROUND AND OBJECTIVE:

To compare the use of cyclocryotherapy and diode laser cyclophotocoagulation for the treatment of uncontrolled intraocular pressure.

PATIENTS AND METHODS:

Seventy consecutive patients (70 eyes) treated for high, unresponsive intraocular pressure during a 4-year period with cyclocryotherapy (n = 38) or diode laser cyclophotocoagulation (n = 32) with a follow-up period of at least 3 months (mean follow-up = 15.7 months) were compared for intraocular pressure, visual acuity, and complication rate.

RESULTS:

Mean intraocular pressure was reduced from 40.9 +/- 11.9 to 20.5 +/- 10.3 mm Hg in the cyclocryotherapy group, and from 35.9 +/- 9.3 to 21.3 +/- 10.7 mm Hg in the cyclophotocoagulation group. Intraocular pressure was controlled in 60.5% and 62.5% of eyes, respectively. Deterioration in visual acuity occurred in 31.5% of the cyclocryotherapy group and 37.5% of the cyclophotocoagulation group. Severe visual loss to no light perception was noted in 6 eyes and 2 eyes, respectively, and phthisis bulbi in 2 eyes in the cyclocryotherapy group (5.2%) and 1 eye in the cyclophotocoagulation group (3.1%).

CONCLUSIONS:

Cyclocryotherapy and diode laser cyclophotocoagulation are equally effective in decreasing intraocular pressure in patients with persistent uncontrolled glaucoma, with a lower rate of complications associated with diode laser cyclophotocoagulation.
