| Abstract | ||||
| Background: Although pars plana vitrectomy [PPV] is a posterior segment surgery. It may also affect anterior segment parameters. This study aimed to assess anterior chamber angle [ACA] changes following PPV using anterior segment optical coherence tomography [AS-OCT] imaging. The aim of the work: This study aimed to assess changes in anterior chamber angle parameters following pars plana vitrectomy for different etiologies using anterior segment OCT imaging Patients and Methods: This prospective study included twenty-nine cases [thirty eyes] whom indicated for pars plana vitrectomy surgery. AS-OCT imaging of ACA was done before and after three months post-operatively then ACA in degrees and AOD 500 was measured. Results: In this study, we enrolled 29 patients [30 eyes as one patient was operated bilaterally] undergoing PPV [with or without intraocular tamponade]. The median [IQR] age of them were 50 [35 – 54] years. Twelve patients [40%] were males, and seventeen [60%] patients were females. According to the patient’s diagnosis, 40% were tractional retinal detachment [on top of advanced diabetic eye disease], 30% were rhegmatogenous retinal detachment and 30% were diagnosed as diabetic vitreous hemorrhage. The anterior chamber angle parameters were measured using AS-OCT imaging before and 3 months following PPV. The ACA° and AOD 500 values were changed [reduced] significantly following PPV at three months postoperatively [P = 0.001]. Conclusions: Despite the limitations of this study, ASOCT demonstrated that there was a significant difference between preoperative and post-operative ACA & AOD500 measurements following PPV. | ||||
