Abstract

Purpose: This study measure the changes in Anterior Chamber Depth (ACD) and Axial Length (AL) after scleral buckle (SB) surgery or Pars Plana Vitrectomy (PPV) for the repair of rhegmatogenous Retinal Detachment (RD). Methods: 102 eyes of patients undergoing rhegmatogenous retinal detachment repair were prospectively reviewed. 49 eyes of 49 patients scheduled to undergo SB surgery and 53 eyes of 53 patients scheduled to undergo PPV. ACD and AL were measured by spectral-domain optical coherence tomography (SD-OCT) and biometry, 1 day before surgery as well as 3 and 4 months postoperatively. Results: ACD was not decreased significantly for patients undergoing PPV surgeries 3 months postoperative (p=0.0843) and 4 months postoperative (p=0.2616). ACD was observed to decrease significantly 3 months (p=0.029) and 4 months (p=0.0027) postoperatively for patients undergoing SB surgeries. AL increased significantly after SB surgery 3 months postoperative (p=0.0020) and 4 months postoperative (p=0.0001). AL not increased significantly after PPV surgery 3 months postoperative (p=0.0863) and 4 months postoperative (p=0.1576). The level of statistical significance was set at p<0.005. Conclusion: Our results showed that SB surgery altered the shape of the eye by changing both ACD and AL, however, PPV not altered ACD and AL significantly. These findings should elucidate the changes to be expected after SB and PPV surgeries.

Highlights

A rhegmatogenous retinal detachment (RD) involves pathologic separation of the neural retina from the pigment epithelium because of break in the retina
Using the Anterior segment-optical coherence tomography (AS-OCT) and IOL Master, we evaluated changes in anterior chamber depth (ACD) and axial length (AL) after scleral buckling (SB) and pars plana vitrectomy (PPV) surgeries
We compare our findings for both surgeries. These results should elucidate the changes to be expected after SB and Pars Plana Vitrectomy (PPV) surgeries

Summary

Introduction

A rhegmatogenous retinal detachment (RD) involves pathologic separation of the neural retina from the pigment epithelium because of break in the retina. Rhegmatogenous RD leads to the loss of visual function and usually requires prompt surgical therapy. RDs can be managed by pneumatic retinopexy, scleral buckling (SB) or vitreoretinal surgery. SB involves the use of an encircling or segmental element and was introduced in 1957 by Schepens et al These external techniques may lead to changes in axial length but may cause a reduction in anterior chamber depth (ACD) [1,2,3,4]. SB surgery changes the shape of the eye, altering the degree of corneal curvature as well as AL [5,6,7,8,9,10]
