It has been proposed that immediate postoperative choroidal detachment is caused by the imbalance between the tissue tension and the intravascular pressure, which occurs following sudden hypotonia.The purpose of my study was to determine the incidence of immediate choroidal detachment following operations for glaucoma. Ideally, the fundi should be examined immediately after surgery. I was unable to do so, for all these patients had received miotic therapy before surgery. The fundi were examined by indirect ophthalmoscopy after they had achieved full mydriasis, usually 14 to 18 hours after the operation.The patients fell
