[Pre- and postoperative choroidal detachment in retinal surgery (author's transl)].

Detachment of the choroidea after retinal detachment surgery is a very common finding. The combination of rhegmatogenous retinal detachment and preoperative choroidal detachment is a very rare condition with poor prognosis which has received only very little attention in the literature. Therefore, we reviewed the last 1000 consecutive case histories of patients who had undergone surgery for retinal detachment in our clinic. We found choroidal detachment postoperatively in 102 cases, but the combination of rhegmatogenous retinal detachment with preoperative choroidal detachment only in four of the 1000 patients. To evaluate the causative factors we recorded some datas, e.g., preoperative IOP, previous ocular trauma, refractive error. The congruent findings in the four cases are discussed.
