Cyclocryotherapy in primary glaucoma: intraocular pressure reducing effects and complications.

As an alternative treatment, we performed a cyclocryotherapy in a series of 27 eyes with chronic narrow angle and chronic open angle glaucoma. Intraocular pressure control was achieved in 91% of the eyes after a mean follow-up period of 38 months. Topical anti-glaucoma medication was needed in 65%. The complications were minor and transient. No serious complications were seen.
