ABSTRACT

Objective: compare the results of treatment with diode laser transscleral cyclophotocoagulation using Nidek probe and G-probe for eyes with painful absolute glaucoma of patients cared for at the Glaucoma Service of "Ramón Pando Ferrer" Cuban Institute of Ophthalmology during one year.
Methods: a prospective comparative study was conducted of 50 eyes randomly distributed in two groups: 25 treated with Nidek probe and 25 with G-Probe. The following variables were analyzed and compared: intraocular pressure, pain, hypotensive drugs used, and postoperative complications before and after application of the treatment.
Results: before treatment, the 50 eyes were hypertensive, whereas three months later intraocular pressure values were considered to be normal in both study groups. A statistically significant variation was found (p= 0.0000). All the patients stated having had ocular pain previously. The two groups showed a satisfactory reduction in pain, with similar results between them. The number of hypotensive drugs was significantly reduced, and most eyes did not require any more drug therapy after three months. The number of associated complications was slightly higher in the eyes treated with Nidek probe. Uveitis and hypertensive peaks in the immediate postoperative period were the most outstanding events with the use of both probes.
Conclusions: diode laser transscleral cyclophotocoagulation satisfactorily reduces intraocular pressure values and pain with the use of both probes. Most of the eyes treated do not require hypotensive drug therapy after 3 months. The cyclodestructive procedure is safe, causing a slight number of complications with the use of both probes.
