Cryotherapy in Ophthalmology

چکیده
Cryogens have been used to freeze living tissue for the purpose of treating benign and malignant lesions. Within the last century, ophthalmologists have found cryotherapy to be useful in treating a variety of ocular pathologies. Here, we review the history of cryotherapy, its introduction to the field of ophthalmology, its proposed mechanism of action, and its current applications in treating surface and intraocular eye disease.
