In retinal detachment surgery, the treatment of the choroid to create an exudative chorioretinitis may cause vitreous shrinkage. Clinically, this shrinkage may be seen when excess reaction is created with either photocoagulation or diathermy. Such vitreous change could lead to a recurrent retinal detachment secondary to the vitreous traction or to "massive vitreous retraction" (massive preretinal fibrosis). These phenomena are well documented in the literature.1-7
In view of the recent interest in the use of cryopexy for the treatment of retinal detachment, the present investigation was undertaken to assess the histologic effect on the vitreous of subfreezing temperatures applied to the sclera. The changes were compared with those which occur with minimally applied Mira diathermy and Zeiss photocoagulation. We found that with the cryopexy treatment, the vitreous changes were quite insignificant. Thus, cryopexy may be more innocuous than diathermy or photocoagulation as far as the vitreous is concerned.
