[Cryo-marker for scleral marking of retinal holes (author's transl)].

According to the Lincoff's procedure, a cryoprobe is used for the localization of retinal holes. A cryo-marker developed for Keeler-cryoprobes simplifies the marking of the scleral impression of the cryoprobe, which is often invisible after thawing. The cryo-marker is fixed on the cryoprobe before cryotherapy. During thawing the toothed ring of the cryo-marker is pushed downwards and placed on the sclera. The centre of the ring on the sclera can now be marked by cauterization after the removal of the cryoprobe.
