[Clinical observations of choroidal hemorrhage and choroidal effusion. A contribution on expulsive bleeding].

A prospective study covering a period of 10 years is presented, which deals in particular with expulsive and nonexpulsive hemorrhages after intracapsular cataract extraction and with massive choroidal hemorrhage. In 7230 intracapsular cataract operations 2 expulsive and 6 nonexpulsive hemorrhages were seen, as well as 1 case of choroidal effusion. During the same period 9 cases of spontaneous massive choroidal hemorrhage were referred for inpatient treatment. The importance of choroidal effusion must be pointed out, even though it is much less common than choroidal hemorrhage. The precise mechanism of choroidal effusion seems to be unknown. On the other hand a massive hemorrhage will probably lead to an expulsive hemorrhage when it coincides with opening of the bulbus. In the light of the author's statistics it appears to be a change occurrence.
