Objectives of Study: |
Primary Research Objective: To investigate the effects and mechanisms of retinal reattachment surgery on choroidal blood flow, and the differences in choroidal blood flow caused by different surgical methods (SB and PPV surgeries). Secondary Research Objectives: (1) To investigate the effects of retinal detachment reattachment surgery on retinal blood flow. (2) To explore the correlation between changes in choroidal blood flow after retinal detachment reattachment surgery and postoperative visual prognosis. (3) To investigate the effects of scleral buckle surgery on anterior chamber parameters and their correlation with increased intraocular pressure (IOP). (4) To investigate the effects of scleral buckle surgery on iris blood flow. |
