INTRODUCTION: Choroidal coloboma is a congenital defect caused by an inadequate closure of embryonic fissure. About 40% of the eyes with the choroidal coloboma (CHC) develop the retinal detachment (RD). It is extremely difficult to manage these cases due to the lack of pigmentation at the site of choroidal coloboma. OUTLINE OF CASES: This is a case series of five patients with CHC and RD who were successfully operated using one of two different surgical techniques: pars plana vitrectomy (PPV)+silicone oil internal tamponade and/or scleral buckle with encircling band with laser photocoagulation (SB+EB+LPC) around the coloboma. The purpose of this paper is to present how to successfully handle patients with CHC, who have concurrent retinal detachment in the same eye and to compare two different techniques and indications for the predominant use of one of them in a specific case. CONCLUSION: Both surgical techniques can be applied with equal success in the operation of retinal detachment in eyes with the chorioidal coloboma. Which one will be used depends only of the posterior segment of eye findings. We use scleral buckling in cases with RD accompanied by CHC when the peripheral break is evident and there are no breaks in the coloboma itself. We also perform, 2-3 days after surgery, laser burns around the coloboma, which is our modification of this technique. In all other cases it is indicated to perform PPV+silicon oil internal tamponade.
