Abstract :
Introduction: Ciliary body destruction has been performed with many techniques with considerable differences in efficacy and complication rates. Among these methods, cyclo-cryotherapy is noninvasive, Simple and very economical to treat uncontrolled IOP in refractory absolute glaucoma.
Objective: To assess the efficacy of cyclo-cryotherapy, in painful blind refractory absolute glaucoma.
Methods: Prospective study of 34 patients with blind refractory absolute glaucoma who were treated with Cyclo-cryotherapy. Cyclo-cryotherapy treatments were performed with retinal cryoprobe of 3.3 mm diameter. The temperature of each Cyclo-cryotherapy spot was -80°C and each spot was maintained in Place for 60 seconds. Four Cyclo-cryotherapy spots were placed in each quadrant. Repeated measures ANOVA was used to find the difference between preoperative and postoperative intraocular pressure.
Results: The mean baseline pretreatment intraocular pressure (IOP) in all eyes was 59.76 /-5.14 mmHg, which was decreased to a mean IOP at last follow-up of 16.29 /-2.42 mmHg.
Conclusions: Cyclo-cryotherapy is a simple effective procedure to lower IOP and is a reasonable treatment option for refractory absolute glaucoma patients who experience with ocular pain and headaches, in rural health care setup.
