Management of retinal detachment with choroidal coloboma

Seventeen eyes with retinal detachment secondary to retinal breaks in the colobomatous area were managed by vitrectomy procedures. Endodrainage was done through the break in the colobomatous area, with simultaneous fluid-air exchange. Endolaser photocoagulation was performed along the colobomatous margin posteriorly, while the anterior portion was treated by transscleral cryopexy. Silicone oil was then exchanged with air. In nine cases, the silicone oil had to be removed for complications such as emulsification, glaucoma, and keratopathy; in three of these eyes, oil removal resulted in recurrent retinal detachment. At the 2-month follow-up visit, there was 100% anatomic success, and 12 eyes (70.6%) recovered visual acuity of 10/200 or better. Of the 11 eyes with follow-up of more than 6 months, in 9 (81.8%) the retina remained reattached at last-follow up, and in 6 eyes (54.5%) a visual acuity of 10/200 or better was obtained.
