Method: Pseudophakic patients who undergo PPV were enrolled in this prospective study between October 2012 and April 2015. Study included patients in whom intraocular tamponade was not used during PPV operation. UBM measurements were performed both before and 10 days after the operation. Anterior chamber depth (ACD) was measured using axial images of anterior segment. Trabecular meshwork-iris angle (TIA), ciliary body thickness (CBT), sclera thickness (ST), trabecular meshwork-ciliary process distance (T-CPD), iris-ciliary processes distance (I-CPD), and iris thickness (IT) were measured at temporal quadrant based on radial section images of the angle. Values measured before and after the operation were statistically compared with each other. Results: This study included 30 patients (18 females, 12 males) that underwent an operation ultrasound biomicroscopy (UBM) after pars plana vitrectomy (PPV) operation without use of tamponade. Mean age was 69.6 ± 9.1 (55 - 85) years. Eighteen operations occurred on the left eye whereas twelve operations occurred on the right eye. CBT1, CBT2, CBT Max, T-CPD, and I-CPD were significantly decreased after operation when compared with the values of baseline (before) (p = 0.018, p = 0.012, p = 0.001, p = 0.033, p = 0.015, respectively). Other evaluated parameters did not show statistically significant changes after the operation (p > 0.05). Discussion: PPV results in significant changes in ciliary body morphology together with changes in anterior segment parameters in pseudophakic cases.展开更多
