[Comparison of the methods of surgical treatment of retinal detachment caused by dialysis retinae at the ora serrata].

In the period of 1972-1973 in the Poznań Department of Ophthalmology were performed 23 operations of scleral infolding with diathermocoagulation in cases of ora serrata dialysis (giant tears were not included in this group). Fifteen years later 20 persons were called for examination. Examined were: the visual acuity, evaluation of the lens and the condition of the retina was checked by a tree-mirror lens with a particular attention for the site of infolding and the appearance of the macula. The 2d group consisted of 20 cases of ora serrata dialysis who underwent surgical procedure of scleral invagination with the use of Lincoff sponge in the form of a parallel implant--connected with cryopexy (period 1984-1985). After such a long time both methods showed to be successful in the term of anatomical effect (90-95%) instead the functional result depended on macular changes, the period of detachment, the character of the trauma, the presence of demarcation lines and on pigmentary changes of the retina.
