Purpose The aim of this study was to compare the changes in anterior segment parameters induced by pars plana vitrectomy (PPV) and silicone oil injection in phakic and pseudophakic eyes.
Patients and methods This is a prospective comparative study that included 40 eyes with rhegmatogenous retinal detachment that underwent vitrectomy and silicone oil injection. They were divided equally into two groups. Group 1 included phakic eyes and group 2 included pseudophakic eyes. Anterior segment parameters were documented by using a CSO Camera (Costruzione Strumenti Oftalmici) before and 1 month after surgery. The changes in the following parameters were compared between the two groups: anterior chamber depth (ACD), anterior chamber volume (ACV), anterior chamber angle (ACA), central corneal thickness (CCT), corneal volume (CV), horizontal anterior chamber diameter, and surgically induced astigmatism.
Results At 1 month postoperatively, in group 1, there was a significant decrease in the mean of ACA and ACV as compared with the preoperative values (P=0.024 and 0.011, respectively). In group 2, there was a significant decrease in the 1-month postoperative mean of ACD, ACA, and ACV as compared with the preoperative values (P=0.021, <0.0001 and 0.015, respectively) and a significant increase in the mean of CCT and CV values (P<0.0001 and 0.002, respectively). In group 2, there was more reduction in ACD, less reduction in ACA, and higher increase in CCT and CV as compared with group 1 (P=0.021, 0.001, <0.0001, and 0.023, respectively).
Conclusion The presence of the crystalline lens acts as a barrier which decreases the changes in the anterior segment parameters and improves the functional outcome following PPV and silicone oil injection as compared with pseudophakia. Therefore, it may be useful to stabilize the anterior segment in patients with PPV and silicone oil injection.
