Abstract:
Cyelocryotherapy using nitrogen monoxide was performed on 28 patients (28 eyes) with secondary glaucoma following penetrating keratoplasty, which had failed to respond to anti-glaucoma drugs and routine filtering procedures. All patients were followed up for more than one year. Intraoeular pressure was well under control in 89% of the eyes. The graft remained clear in 85%. The effective visual function was preserved in 82%. Our study showed that timely intervention, precisely controlled temperature) timing, extent of cryotherapy, and post-operative use of anti-rejection agents were key factors to suceess. Over-treatment, which may lead to atrophy of the eye, must be avoided. The effort should not be given up following under-treat-ment in the initial procedure.
