1/4. Delayed suprachoroidal hemorrhage following viscocanalostomy.Delayed suprachoroidal hemorrhage is a rare complication of conventional glaucoma surgery. Viscocanalostomy is one of the new surgical techniques used in glaucoma surgery that may theoretically protect against suprachoroidal effusion and hemorrhage due to the nonpenetrating nature of the procedure. Delayed suprachoroidal hemorrhage developed in a 92-year-old white woman following viscocanalostomy. This case demonstrates that the risk of suprachoroidal hemorrhage may not be completely eliminated after a nonpenetrating glaucoma procedure such as viscocanalostomy.- - - - - - - - - - ranking = 1keywords = effusion (Clic here for more details about this article) |
2/4. Expulsive choroidal effusion: case report of a rare complication of intraocular surgery.A case of expulsive choroidal effusion occurring during extracapsular cataract extraction in a 75 year old woman is presented. The episode occurred at the time of insertion of the pseudophake into the ciliary sulcus. The woman had pre-existent filtering bleb and was hypertensive, factors which may have contributed to the episode. Although this is dramatic occurrence, it needs to be distinguished from expulsive choroidal hemorrhage which carries a much worse porgnosis. In this instant, management was expectant and patient attained 6/12 with over-refraction. It is recommended that patients who may be at risk for expulsive choroidal effusion should have in the bag pseudophake fixation rather than sulcus fixation to obviate pressure on the circular vascular arcade.- - - - - - - - - - ranking = 6keywords = effusion (Clic here for more details about this article) |
3/4. Choroidal hematoma and effusion: evaluation with MR imaging.To evaluate the usefulness of magnetic resonance (MR) imagining in the evaluation of choroidal pathologic conditions, the authors studied 15 patients with either choroidal hematoma or choroidal effusion with a 1.5-T MR imager. These two lesions were reliably distinguished from each other on the basis of MR findings. Choroidal hematomas appeared as lenticular-shaped masses in the wall of the eyeball, and signal intensity depended on the age of the hematoma. Choroidal effusions appeared as crescentic or ring-shaped areas of increased signal on both T1- and T2-weighted images in an anatomic distribution corresponding to the choroidal and suprachoroidal spaces.- - - - - - - - - - ranking = 6keywords = effusion (Clic here for more details about this article) |
4/4. Survey of risk factors for expulsive choroidal hemorrhage: case reports. Substantiation of the risk factors and their incidence.To evaluate the interaction of risk factors for expulsive hemorrhage, we evaluated 3 cases of expulsive hemorrhage and 2 of acute intraoperative choroidal effusion that occurred at the University of Tsukuba Hospital over a 16-year-period and investigated the common findings in these 5 cases. We also selected randomly 500 cataractous cases operated at the University of Tsukuba Hospital and investigated the probabilities of risk factors for expulsive hemorrhage in these control cases. The 5 affected patients exhibited more than four risk factors of expulsive hemorrhage. The probability of more than four risk factors being involved in any cataract operation was approximately 0.33% (0.17 approximately 0.67%; 95% confidence interval). The incidence of expulsive hemorrhage at our hospital was approximately 0.2%, which is similar to the probability rate. Thus, we concluded that the development of expulsive hemorrhage was proved to be related to an accumulation of the risk factors for expulsive hemorrhage.- - - - - - - - - - ranking = 1keywords = effusion (Clic here for more details about this article) |
