Acute Angle-Closure Glaucoma Prevention and Prognosis Regular eye examinations with an ophthalmologist might identify those who are at risk for acute angle-closure glaucoma. In some social people who are at high risk, a laser iridotomy could be performed to prevent an attack of severe angle-closure glaucoma. If a patient has developed primary severe angle-closure in one eye, the ophthalmologist may suggest laser beam iridotomy in the other eye to prevent an attack. The prognosis for acute angle-closure glaucoma is normally favorable with early recognition and treatment. Vision loss can occur without prompt treatment. If pain and/or decreased vision occur, the individual should promptly seek professional treatment from an ophthalmologist..Samples had been processed as explained previously28 at each regional hospital. Subjects who were found to possess a hemoglobin degree of 75 ng per milliliter or even more were invited to endure colonoscopy. Information regarding quality indicators for colonoscopy are given in the study protocol and in Desk 1 in the Supplementary Appendix, available at NEJM.org. The companies weren’t involved in the design of the analysis, in the evaluation or interpretation of the data, or in the preparation of the manuscript.
